Titanium Implants

Dental Implants have become a common and predictable way to replace missing teeth.  A dental implant is a titanium root which is placed in the jaw.  It takes about 2 to 3 months for the dental implant to become fixed in the jaw.  After this period, a tooth can be fabricated out of porcelain to be fixed on top of the implant. The porcelain tooth looks and feels natural and functions like any other tooth in your mouth.

Internal Whitening of a Single Tooth

In this blog,  we are going to talk about single tooth discolouration and the procedure involved in whitening a single discoloured tooth.

Discolouration of a single tooth usually occurs after trauma to that tooth.  A tooth may become discoloured due to the leakage of blood into the porous dentin layer. This changes the color of the dentin, which can be seen through the enamel. In adults, the teeth can turn pink or red right away or over  time,  they can also turn brown or gray.

The type of dental treatment depends upon the colour the tooth takes and the type of injury.

If the tooth needs a root canal, this will not change the color of the tooth. A procedure called “internal bleaching” has to be done. This is a low risk, routine procedure used to improve the esthetics of a single discoloured tooth.

Although it is very low risk, there is still the risk of cervical root resorption and also of recurrence, so the procedure may have to be redone five or ten years later.

Materials used are peroxide (hydrogen or carbamide). The tooth is accessed from the back or lingual side and the pulp chamber is sealed. Materials are left in place and results are assessed a few days after. If necessary, the procedure can be redone to a maximum of three times. With the materials available today, this procedure is fairly predictable and often results in a dramatic change in tooth colour.
