Bleaching products brighten teeth that have been stained or darkened by food, tobacco use, injury or aging. In-office teeth bleaching takes place over a series of one-hour appointments at the office. First, your teeth will be examined and cleaned to make sure there are no cavities, loose fillings, gum problems or other issues that may be exacerbated by the bleaching process. A custom-fit mouthtray will be made for your teeth. Then the bleaching gel is applied to your teeth in the tray.
Dental bonding can improve the appearance of chipped, broken, cracked and stained teeth and fill in spaces between teeth. Dentists apply a thin layer of tooth-colored composite resin to the teeth to restore chips and cracks, fill in gaps or cover stains, and provide patients with a more attractive and functional smile.
First, a thin layer of plastic material is applied to the tooth's surface. Then the dentist sculpts the bonding material to the desired shape and bonds it to the tooth using a special light. The bonding material comes in many colors so it will be possible to match the shade of your teeth. Once the plastic has hardened, it is polished until it is entirely smooth. The dental bonding procedure takes one to two hours and its results last about 10 years.
A dental bridge (also known as a fixed partial denture) is a dental prosthetic that effectively replaces a missing tooth. Most bridges are situated between two dental crowns that hold the prosthetic in place. To ensure that a successful repair is made, the teeth adjacent to the target area are reduced to the proper pattern that will fit the new tooth's material and shape. This also allows for seamless integration with the teeth directly above or below the replacement during chewing. Precise affixation of this implant is vital to proper functioning of the tooth once the patient leaves their dentist's office.
Careful planning must be followed to ensure the pontic will be supported adequately by the crowns on either side. The rule that most dentists employ is called Ante's Rule, which states that, "the combined roots' Surface Area of the abutment (supporting) teeth must be equal or larger than that of the tooth being replaced." If the teeth immediately next to the missing tooth do not satisfy this requirement, additional abutment teeth may be employed.
