The long-term success of implants is determined, in part, by the forces they have to support. As implants have no periodontal ligament, there is no sensation of pressure when biting so the forces created are higher. To offset this, the location of implants must distribute forces evenly across the prosthetics they support.(pp15–39) Concentrated forces can result in fracture of the bridgework, implant components, or loss of bone adjacent the implant. The ultimate location of implants is based on both biologic (bone type, vital structures, health) and mechanical factors. Implants placed in thicker, stronger bone like that found in the front part of the bottom jaw have lower failure rates than implants placed in lower density bone, such as the back part of the upper jaw. People who grind their teeth also increase the force on implants and increase the likelihood of failures.(p201–208)

Planning for dental implants focuses on the general health condition of the patient, the local health condition of the mucous membranes and the jaws and the shape, size, and position of the bones of the jaws, adjacent and opposing teeth. There are few health conditions that absolutely preclude placing implants although there are certain conditions that can increase the risk of failure. Those with poor oral hygiene, heavy smokers and diabetics are all at greater risk for a variant of gum disease that affects implants called peri-implantitis, increasing the chance of long-term failures. Long-term steroid use, osteoporosis and other diseases that affect the bones can increase the risk of early failure of implants.(p199) Dental Implant Patient from London, UK - 15/09/2016
Females generally have slightly whiter teeth than males, partly because females' teeth are smaller, and therefore there is less bulk of dentin, partially visible through the enamel layer. For the same reason, larger teeth such as the molars and the canine (cuspid) teeth tend to be darker. Baby teeth (deciduous teeth) are generally whiter than the adult teeth that follow, again due to differences in the ratio of enamel to dentin. As a person ages the adult teeth often become darker due to changes in the mineral structure of the tooth, as the enamel becomes less porous and phosphate-deficient. The enamel layer may also be gradually thinned or even perforated by the various forms of tooth wear. What different dental implants are available?
To whiten the natural tooth shade, bleaching is suggested. It is a common procedure in cosmetic dentistry, and a number of different techniques are used by dental professionals. There is a plethora of products marketed for home use to do this also. Techniques include bleaching strips, bleaching pens, bleaching gels and laser tooth whitening. Bleaching methods generally use either hydrogen peroxide or carbamide peroxide which breaks down into hydrogen peroxide.

It has been suggested that radiotherapy can negatively affect the survival of implants. Nevertheless, a systemic study published in 2016 concluded that dental implants installed in the irradiated area of an oral cavity may have a high survival rate, provided that the patient maintains oral hygiene measures and regular follow ups to prevent complications.

Another purported method of naturally whitening the teeth is through the use of activated charcoal. Technically, activated charcoal doesn't "whiten" your teeth, it simply helps remove stains from the surface your teeth. It is important to highlight some dentist believe activated charcoal should not be used for teeth whitening whilst others believe there is rational for using activated charcoal for teeth whitening as it may help absorb discolourations in your tooth enamel. Dr. Bashar - Dental Implant Expert in London
More than 60% of Americans have naturally sensitive teeth. This is most often caused by genetics, thin enamel, or crack/damaged teeth. During the whitening process, it is completely normal for sensitivity to occur. The teeth become temporarily dehydrated which reduces their ability to insulate the nerve from changes in temperature. Sensitivity will disappear 12-36 hours after whitening. Dentists and hygienists recommend a post-whitening fluoride treatment to nourish the teeth and promote rehydration. 24 Hour Emergency Dentist Kings Cross
While Crest Gentle Routine strips are great for sensitive teeth, the lower peroxide level means it also takes longer to see full results — 28 days compared to Glamorous White’s 20 days — which is something to keep in mind if you’re whitening for an upcoming event. Additionally, the experts we consulted, our testers, and findings from beauty sites such as TotalBeauty.com and Men’s Health agreed that the higher the peroxide content, the better the final results.

Next, the bone around the implant heals in a process called osseointegration. What makes an implant so strong is that the bone actually grows around it and holds it in place. Osseointegration means “combines with the bone” and takes time. Some patients might need to wait until the implant is completely integrated, up to several months, before replacement teeth can be attached to the implant. Other patients can have the implants and replacement teeth placed all in one visit. Cosmetic Dentistry - London Cosmetic Dentists londonsmile.co.uk Video
As with most treatment procedures in dentistry today, dental implants not only involve scientific discovery, research and understanding, but also application in clinical practice. The practice of implant dentistry requires expertise in planning, surgery and tooth restoration; it is as much about art and experience as it is about science.

It is also possible to have stains inside the tooth. These are called intrinsic stains. For example, intrinsic stains can be caused by exposure to too much fluoride as a child while teeth are developing. Other causes include tetracycline antibiotics. They can stain a child's teeth if taken by a mother during the second half of pregnancy or by a child who is 8 years old or younger. Teeth are still developing during these years. Trauma may also darken a tooth. Dentist in london- what is root canal treatment pt 1
The gingiva surrounding a tooth has a 2–3 mm band of bright pink, very strong attached mucosa, then a darker, larger area of unattached mucosa that folds into the cheeks. When replacing a tooth with an implant, a band of strong, attached gingiva is needed to keep the implant healthy in the long-term. This is especially important with implants because the blood supply is more precarious in the gingiva surrounding an implant, and is theoretically more susceptible to injury because of a longer attachment to the implant than on a tooth (a longer biologic width).(pp629–633) Cheap Dentures London UK | Cerec Dentistry | Dental Implants Costs | Invisible Braces Central London
The aim of the oral hygiene phase of treatment is to reduce the number of bacteria in the mouth and therefore reduce the level of inflammation. Your dental practitioner will first explain the causes of your periodontitis and explain exactly how to keep your teeth and gums clean. You will be given individual advice on how to use the various cleaning aids most effectively; for example, the most appropriate tooth brushing technique and the correct use of dental floss and interdental brushes.

In some people, gingivitis progresses to periodontitis – with the destruction of the gingival fibers, the gum tissues separate from the tooth and deepened sulcus, called a periodontal pocket. Subgingival microorganisms (those that exist under the gum line) colonize the periodontal pockets and cause further inflammation in the gum tissues and progressive bone loss. Examples of secondary causes are those things that, by definition, cause microbic plaque accumulation, such as restoration overhangs and root proximity.

For whitening at home, your dentist can make trays to hold the whitening gel that fit your teeth precisely. Home whitening gel usually needs to be applied daily for two to three weeks. Over-the-counter kits also are widely available for home use. They provide trays to hold the gel, or whitening strips that stick to your teeth. Talk to your dentist if you want to use these home products. Be sure to follow directions to avoid overuse and possible damage to your teeth and mouth.
In the first phase of your implant procedure, you’ll receive a local anesthetic to keep you free from pain. Then the doctor will place screws, usually titanium, into your jaw bone to serve as the roots of your new teeth. At this point, the implant looks like a small metal bead on the surface of your gum. Over time, the titanium fuses to your jawbone, making dental implants a much longer lasting solution than dentures.

When it comes to whitening, higher peroxide contents and greater contact time with your teeth deliver better results. Unsurprisingly, the low contact time of pens mean they aren’t the most powerful whiteners, which is why we recommend the Go Smile pen as a supplement to your whitening regimen. In other words, the Go Smile pen isn’t the best bet for deeper whitening, but is a handy sidekick to any of our other picks.
Whitening toothpastes are different to regular toothpastes in a way that they contain a higher content of abrasives and detergents to fight off tougher stains. Most contain low concentrations of carbamide/hydrogen peroxide (bleaching agents) – this lightens the colour of teeth. These whitening toothpastes make teeth one to two shades lighter. Toothpastes (dentifrices) which are advertised as "whitening" rarely contain carbamide peroxide, hydrogen peroxide or any other bleaching agent. Rather, they are abrasive (usually containing alumina, dicalcium phosphate dehydrate, calcium carbonate or silica), intended to remove surface stains from the tooth surface. Sometimes they contain enzymes purported to break down the biofilm on teeth. Unlike bleaches, whitening toothpaste does not alter the intrinsic color of teeth. Excessive or long term use of abrasive toothpastes will cause dental abrasion, thinning the enamel layer and slowly darkening the appearance of the tooth as the dentine layer becomes more noticeable. An alternative method of whitening at home, which competes with the use of a whitening paste, is the use of a patent whitening mouthwash. The mouthwash shows marginally better efforts at whitening compared to the use of paste. Dental Implants Dentist Camden
Eat more vitamin C-rich foods. It's not just lemons that can help with gum disease, but also other foods full of vitamin C such as oranges, grapes, guava, kiwi mango, papaya, bell peppers, and strawberry.

A toothache is a pain on or around a tooth. It may be caused by a variety of things from a cavity, abscess, or even sinusitis. Toothache symptoms include pain, headache, ear ache, bad taste in the mouth, and gum swelling. Dental X-rays and other tests performed by a dentist are used to diagnose the cause of a toothache. Tootache treatment depends on the underlying cause. Taking proper care of the teeth and gums can help prevent toothache. Part 1-Dental Implant Placement with Bone Grafting and Membrane
Antibiotic therapy can be combined in various ways to help treat gingivitis, periodontal disease, and especially ANUG. Chlorhexidine (Peridex) is an antibiotic mouthwash that can be used under direction of a dentist to help reduce the bacteria that cause gum disease. Pellets or gels like PerioChip that contain the antibiotic chlorhexidine or doxycycline can be placed in deep gum pockets after deep scaling and root planing to kill stubborn bacteria and reduce the size of periodontal pockets. These modes of delivering antibiotic therapy are very effective because the antibiotic is released slowly over the course of about seven days. Additional treatment such as xylocaine and NSAIDs may be needed for pain control in chronic gingivitis and ANUG. Dental London - The Dental Implant Centre

Tray-based tooth whitening systems, purchased either over-the-counter or from a dentist, involve filling a mouth guard-like tray with a gel whitening solution -- which contains a peroxide-bleaching agent. The tray is worn for a period of time, generally from a couple of hours a day to every day during the night for up to four weeks and even longer (depending on the degree of discoloration and desired level of whitening).

The dentist or oral health professional will examine your gums with a probe to measure the spaces between the tooth and gum. This will determine the health of your gums and supporting structures. If necessary, the dentist or oral health professional will instruct you in tooth cleaning techniques or may clean your teeth professionally to remove any plaque and calculus (hardened plaque).
There are plenty of websites devoted to teeth whitening that claim to know the exact breakdown, but, since there's no way to verify their information, we did not accept those as reliable. However, experts generally agree that home teeth whitening products have up to 10 percent hydrogen peroxide, while professionally applied tooth whitening treatments can contain from 25 to 40 percent. As a result, we would suggest being skeptical if you read anything not directly attributable to the manufacturer that claims that an over-the-counter whitening product contains more than 10 percent whitening agent.

As dental plaque or biofilm accumulates on the teeth near and below the gums that is some dysbiosis of the normal oral microbiome. As of 2017 it was not certain what species were most responsible for causing harm, but gram-negative anaerobic bacteria, spirochetes, and viruses have been suggested; in individual people it is sometimes clear that one or more species is driving disease. Research in 2004 indicated three species gram negative anerobic species: Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Bacteroides forsythus and Eikenella corrodens.

If the progress of periodontal inflammation is not halted, the supporting structures of the teeth, including the surrounding bone, are destroyed. The teeth eventually loosen and are lost, or require extraction. Other problems patients may experience include painful abscesses, drifting of the teeth which may interfere with eating, and unsightly lengthening of the teeth with exposure of the roots, as a result of gum recession.
If you have periodontitis, regular follow-ups with a dentist are essential to ensure that the disease doesn’t continue. You’ll have to change your dental hygiene habits and cooperate fully with your dentist’s instructions for a positive outcome. The long-term outlook depends on your own efforts with oral hygiene and the ongoing assessment of your dentist.
As with any toothache, you can keep abscess pain under control with cold compresses, salt water rinses, and sticking to soft foods. Your dentist may prescribe antibiotics for you to take before you come into the office; this often helps alleviate pain as it helps your body fight off the infection. Abscesses are often treated with a root canal procedure. If the tooth is badly infected, an extraction is an affordable treatment option.

Sometimes, a surgical procedure is carried out to clean away plaque bacteria and deposits that are under the gum within periodontal pockets and on the root surfaces at the furcations (where the roots diverge). These areas are inaccessible to brushes and floss and inflammation will persist in these sites as long as bacteria are allowed to colonize them. Under local anaesthesia, the gum is lifted away and the root surfaces are cleaned under direct vision to ensure that all bacteria are removed. Sometimes, it is possible to treat bone loss at the same time using a special regenerative treatment. At the end of the procedure, the gums are sutured back into place around the teeth.

The first thing to do is visit your dental team for a thorough check-up of your teeth and gums. They will measure the 'cuff' of gum around each tooth to see if there is any sign that periodontal disease has started. X-rays may also be needed to see the amount of bone that has been lost. This assessment is very important, so the correct treatment can be prescribed for you. Eastman Dental Hospital
If gum disease is more advanced, scaling and root planning can be performed to treat diseased periodontal pockets and gum infection. A dental hygienist uses an ultrasonic scaling device to remove plaque, tartar and food debris above and below the gum line, and hand scales the tooth and root surfaces to make them smooth and disease free. Laser treatments are also sometimes used to remove tartar deposits. If periodontal pockets are more than 5 millimeters deep, that is, if you have moderate to severe periodontitis, gingival flap surgery may be performed by a periodontist to reduce periodontal pockets, as well as bone grafting to restore lost bone.

Age: There is a direct correlation between tooth color and age. Over the years, teeth darken as a result of wear and tear and stain accumulation. Teenagers will likely experience immediate, dramatic results from whitening. In the twenties, as the teeth begin to show a yellow cast, whitening may require a little more effort. By the forties, the yellow gives way to brown and more maintenance may be called for. By the fifties, the teeth have absorbed a host of stubborn stains which can prove difficult (but not impossible) to remove.
Many people do things that can compromise their teeth, without realizing it. For instance, chewing on ice, crunching hard candy or eating popcorn kernels can crack teeth without you even knowing. If you use your teeth to tear open packages instead of using scissors, this can cause tiny cracks in your teeth and in the enamel that protects you teeth that you can’t see with the naked eye.

The more dangerous bacteria are able to thrive and multiply, producing some harmful by-products which stimulate the body’s defensive inflammatory response in the gums. As the disease progresses, chronic inflammation causes the bone of the jaw to be destroyed and the teeth to be lost. In many people, this is a gradual process that takes place over many years and, if detected and treated, can be halted. However, some young adults have a very active form of the disease which causes early loosening and loss of the teeth.

Dental implants are artificial tooth roots that provide a permanent base for fixed, replacement teeth. Compared to dentures, bridges and crowns, dental implants are a popular and effective long-term solution for people who suffer from missing teeth, failing teeth or chronic dental problems. Because they fit, feel and function like natural teeth, dental implants are quickly becoming the new standard in tooth replacement.

Many women who become pregnant think that they should avoid the dentist to keep their pregnancy safe, but they shouldn't miss their dental cleanings as long as they feel strong and comfortable enough. During pregnancy, women are at risk of developing pregnancy gingivitis. Because of the increase in hormones that occurs with pregnancy, the gum tissues are more susceptible to attack from bacteria and other pathogens. Pregnant women will often notice an increase in swollen, bleeding gums even if their oral hygiene has remained consistent. It may be necessary to get dental cleanings more often than usual during pregnancy to help combat this increased risk.
Dentists and dental hygienists measure periodontal disease using a device called a periodontal probe. This thin "measuring stick" is gently placed into the space between the gums and the teeth, and slipped below the gumline. If the probe can slip more than 3 mm (0.12 in) below the gumline, the person is said to have a gingival pocket if no migration of the epithelial attachment has occurred or a periodontal pocket if apical migration has occurred. This is somewhat of a misnomer, as any depth is, in essence, a pocket, which in turn is defined by its depth, i.e., a 2-mm pocket or a 6-mm pocket. However, pockets are generally accepted as self-cleansable (at home, by the person, with a toothbrush) if they are 3 mm or less in depth. This is important because if a pocket is deeper than 3 mm around the tooth, at-home care will not be sufficient to cleanse the pocket, and professional care should be sought. When the pocket depths reach 6 to 7 mm (0.24 to 0.28 in) in depth, the hand instruments and cavitrons used by the dental professionals may not reach deeply enough into the pocket to clean out the microbial plaque that causes gingival inflammation. In such a situation, the bone or the gums around that tooth should be surgically altered or it will always have inflammation which will likely result in more bone loss around that tooth. An additional way to stop the inflammation would be for the person to receive subgingival antibiotics (such as minocycline) or undergo some form of gingival surgery to access the depths of the pockets and perhaps even change the pocket depths so they become 3 mm or less in depth and can once again be properly cleaned by the person at home with his or her toothbrush. Dentist In Holborn Outstanding 5 Star Review by Kate S.
Fillings, crowns, and other restorations. Tooth-colored fillings and resin composite materials used in dental restorations (crowns, veneers, bonding, bridges) do not whiten. Therefore, using a whitening agent on teeth that contain restorations will result in uneven whitening -- in this case, making the teeth without restorations appear lighter than those with restorations. Any whitening procedure should be done prior to the placement of restorations. Cosmetic Dental Surgery - London Smile Dental Practice W1
If the soft bacterial plaque is not removed by brushing, minerals are deposited within it over time and it becomes a hard deposit on the tooth called tartar. The presence of tartar encourages the growth of the bacterial plaque towards the tooth roots. As the inflammation progresses deeper, the attachment of the gum to the root is disrupted and a gap or periodontal pocket is formed between them. This pocket is an ideal place for harmful bacteria to colonize and in which to multiply, therefore driving the disease process forward. In their new habitat, the bacteria release toxins as products of their metabolism, which further trigger the body’s defence mechanisms.

It is possible to have gum disease and have no warning signs. That is one reason why regular dental checkups and periodontal examinations are very important. Treatment methods depend upon the type of disease and how far the condition has progressed. Good dental care at home is essential to help keep periodontal disease from becoming more serious or recurring. Remember: You don’t have to lose teeth to gum disease. Brush your teeth twice a day, clean between your teeth daily, eat a balanced diet, and schedule regular dental visits for a lifetime of healthy smiles.
The perception of tooth color is the result of a complex interaction of factors such as: lighting conditions, translucency, opacity, light scattering, gloss, the human eye and brain. Teeth are composed of a surface enamel layer, which is whiter and semitransparent, and an underlying dentin layer, which is darker and less transparent. These are calcified, hard tissues comparable to bone. The natural shade of teeth is best considered as such; an off-white, bone-color rather than pure white. Public opinion of what is normal tooth shade tends to be distorted. Portrayals of cosmetically enhanced teeth are common in the media. In one report, the most common tooth shade in the general population ranged from A1 to A3 on the VITA classical A1-D4 shade guide. Cosmetic Dental Surgery - London Smile Dental Practice W1

In some cases, the abutment is attached to the dental implant metal post when the post is implanted. That means you won't need an extra surgical step. Because the abutment juts past the gumline, however, it's visible when you open your mouth — and it will be that way until your dentist completes the tooth prosthesis. Some people don't like that appearance and prefer to have the abutment placed in a separate procedure. Glow dentistry, www.glowdentestry.co.uk, hampstead dentist, Mill Hill Dentist. London Dentist
Vital whitening may not improve the appearance of a tooth that has had root-canal treatment because the stain is coming from the inside of the tooth. If this is the case, your dentist will use a different procedure that whitens the tooth from the inside. He or she will place a whitening agent inside the tooth and put a temporary filling over it. The tooth will be left this way for several days. You may need this done only once, or it can be repeated until the tooth reaches the desired shade.
