A typical conventional implant consists of a titanium screw (resembling a tooth root) with a roughened or smooth surface. The majority of dental implants are made out of commercially pure titanium, which is available in four grades depending upon the amount of carbon, nitrogen, oxygen and iron contained.[53] Cold work hardened CP4 (maximum impurity limits of N .05 percent, C .10 percent, H .015 percent, Fe .50 percent, and O .40 percent) is the most commonly used titanium for implants. Grade 5 titanium, Titanium 6AL-4V, (signifying the titanium alloy containing 6 percent aluminium and 4 percent vanadium alloy) is slightly harder than CP4 and used in the industry mostly for abutment screws and abutments.[54](pp284–285) Most modern dental implants also have a textured surface (through etching, anodic oxidation or various-media blasting) to increase the surface area and osseointegration potential of the implant.[55](p55) Refresh Dental a Dental Clinic in London for Cosmetic Dentistry or for Dentist
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[citation needed] 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?
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. Clara Had Pain Free, Top Notch Treatment at Chalton Street
We recruited 39 participants across a wide range of ages to try out our top products. The experiment began with each tester matching their teeth shade to a professional teeth shade guide and snapping a “before” pic. After using the teeth whitening product for the recommended length of time, our testers took an “after” photo, evaluated their new shade, and completed a survey describing the experience.

The information in this 10-module syllabus is intended (1) to meet elements of initial educational/training requirements for Dental Students, Dental Hygiene Students, and Dental Assistant Students related to dental radiography; (2) to provide a framework for an in-service training program in oral healthcare settings to meet annual educational/training requirements as mandated by federal, state, local and professional organizations; and (3) to serve as a resource for oral healthcare personnel wishing to review evidence-based information on specific topics related to dental radiography. A PDF is available for each module that may serve as a convenient resource. Harley Street Dental Clinic - Harley Street Dentist - 020 7486 1059

The long-term complications that result from restoring teeth with implants relate, directly, to the risk factors of the patient and the technology. There are the risks associated with appearance including a high smile line, poor gingival quality and missing papillae, difficulty in matching the form of natural teeth that may have unequal points of contact or uncommon shapes, bone that is missing, atrophied or otherwise shaped in an unsuitable manner, unrealistic expectations of the patient or poor oral hygiene. The risks can be related to biomechanical factors, where the geometry of the implants does not support the teeth in the same way the natural teeth did such as when there are cantilevered extensions, fewer implants than roots or teeth that are longer than the implants that support them (a poor crown-to-root ratio). Similarly, grinding of the teeth, lack of bone or low diameter implants increase the biomechanical risk. Finally there are technological risks, where the implants themselves can fail due to fracture or a loss of retention to the teeth they are intended to support.[47](pp27–51)
The final prosthetic can be either fixed, where a person cannot remove the denture or teeth from their mouth, or removable, where they can remove the prosthetic. In each case an abutment is attached to the implant fixture. Where the prosthetic is fixed, the crown, bridge or denture is fixed to the abutment either with lag screws or with dental cement. Where the prosthetic is removable, a corresponding adapter is placed in the prosthetic so that the two pieces can be secured together.
In the situation where an implant is to be placed in the maxilla (upper jaw) in the back or posterior region, sometimes the available amount of bone may be limited by the presence of the maxillary sinus (air-filled space found in the bones of the face). "Sinus augmentation" or "sinus lift" is performed to raise the sinus floor and graft more bone into the sinus. This will make more bone available to support a dental implant.

Regular teeth cleaning by a dentist removes plaque that may develop, even with careful brushing and flossing. This is very important for getting at areas that are hard to reach on your own. Professional cleaning includes scaling and polishing. This procedure uses instruments to loosen and remove deposits from the teeth. Routine exams may include dental x-rays. Your dentist can catch problems early, so they do not become more serious and expensive to fix.

An estimated two in three Americans have one or more missing teeth, mainly due the rise in  periodontal disease as the population grows older.  Tooth loss and other oral health problems in older Americans recently prompted AARP to declare the “Over 50 Dental Crisis.”  In 2006, Dental Economics reported that more than 30 million Americas are missing all their teeth in one or both jaws.
