A dental implant is a structure that replaces a missing tooth. With screw-like devices, the surgeon inserts an implant into the jawbone, and it acts as an anchor for an artificial tooth, called a crown. A device called an abutment connects the artificial tooth to the dental implant.

The crown is custom-made to fit the person’s mouth and match the color of their teeth. Crowns look, feel, and function like natural teeth.

Implants have several advantages. Trusted Source over dentures, which are removable artificial teeth. Implants:
1. Are more natural and comfortable.
2. Have a higher success rate.
3. Improve chewing function.
4. Lead to a lower risk of cavities developing in nearby teeth.
5. Lead to better maintenance of bone at the site of the lost tooth.
6. Cause decreased sensitivity in nearby teeth.
7. Do not need to be taken out and cleaned every night.

However, dental implants are not suitable for everyone. The implanting devices must bond with the jawbone, so a person’s bones must be healthy before they can undergo implant surgery.

Oral surgery deals with the diagnosis of, and the surgery required by, diseases, injuries, and defects of the human jaws and associated structures. Both dentists and physicians refer a wide variety of special dental problems to the oral surgeon. These may include the removal of impacted and infected teeth and the treatment of cysts, tumours, lesions, and infections of the mouth and jaws. In addition, there are more complex problems, such as jaw and facial injuries, cleft palate, and cleft lip.

Endodontics deals with the treatment of diseases of the inside of the tooth, including the pulp chamber, the pulp canal, and contiguous structures. Root canal therapy and bleaching of nonvital teeth are standard treatments rendered by endodontists.

Minimal intervention dentistry is focused on filling only cavitated regions, leaving non-cavitated decay to be remineralised, thus restoring the tooth while removing as little of the tooth structure as possible, enhancing the strength and aesthetics of the restoration.

Decay is the process or result of demineralisation (softening) of an area of dental tissue, creating a decayed lesion on the tooth. The process of restoring decay begins with an analysis of the decayed lesions together with their location and severity, with particular regard to the state of reversibility. Where decay is reversible, it is referred to as non-cavitated decay, where healing is possible by the hardening process of remineralisation. Where a cavity has formed from excessive demineralisation, the decay has reached the point of no return where the tooth structure has been lost and the decay is permanent and non-reversible. In this situation of cavitated decay, the cavity will have to be filled to restore the tooth.

Orthodontics takes as its aims the prevention and correction of malocclusion of the teeth and associated dentofacial incongruities. Orthodontics has been practiced since ancient times, but methods of treatment involving the use of bands and removable appliances have been prominent only since the beginning of the 20th century. The United States gave impetus to the development of orthodontics, which was recognized as a specialty with the formation of the American Society of Orthodontists in 1900.

The demand for this service extends from the child to the mature adult, although human bone responds to tooth movement best in a person under 18, and it is generally agreed that children benefit more from treatment than do adults. In general, oral health and physical appearance are the two most important reasons for undertaking a course of orthodontic care.

Teeth whitening is a procedure to lighten the color of your teeth and remove stains. You can have it done at a dentist's office, or do it yourself at home.

Tooth whitening is most often done using peroxide-based bleaching agents. At-home systems contain from 3% to 20% peroxide (carbamide or hydrogen peroxides). In-office systems contain from 15% to 43% peroxide.

Generally, the stronger the solution and the longer you keep it on your teeth, the whiter your teeth become. But the higher the percentage of peroxide in the whitening solution, the shorter it should stay on your teeth. Keeping it on longer will dehydrate teeth and increase tooth sensitivity. There are pros and cons to each option, but before you try at-home tooth-bleaching kits, talk to your dentist. Not everyone will see good results. Bleaching will not whiten porcelain crowns or tooth-colored composite bondings.
