When cavities arise, they must be removed and the tooth filled to ensure continued oral health. At My Family Dentists, we use a composite resin, or white filling, that is colored to match your tooth.
Tooth fillings are normally scheduled after a complete dental examination if one or more of your teeth is found to have cavities. Fillings can normally be completed in a single visit. When you arrive, you’ll be given a local anesthetic which will numb your month to prevent any pain. The dentist will also check the color of your teeth against a color chart to properly match the resin color to your tooth color.
After the numbing agent has taken effect, the dentist will begin working on the decayed part of the tooth while an assistant uses a suction tube to remove the freed decay. The dentist works first with drills, lasers, or air abrasion technology to remove the greater portion of the cavity. He/she may then used manual instruments to ensure there is absolutely nothe decay left behind.
Once your tooth is completely free of decay, the dentist will fill the resulting hole. To help the resin adhere more solidly to the tooth, acid is briefly applied to the holeto create small abrasions. Afterward, the correctly colored resin is placed into the hole and shaped to match your tooth’s contours. The resin then must be cured to harden. Curing is a simple process that requires your dentist to direct a laser, which just looks like a blue light, onto the resin for several seconds.
Once the resin is cured, the dentist with smooth it to match the feel of your teeth. Composite resin fillings normally last between five and eight years.
Amalgam, or silver fillings, are also available, if you would prefer. These do not require curing or color matching and normally last longer than the resin composite alternative.
