Composite Fillings


Your dentist at True Dental in Grapevine uses the highest quality materials to provide function and esthetics back to a decayed tooth. Cavities are caused by a specific type of bacteria called streptococcus mutans. The bacteria can be passed on from person to person through kissing, sharing straws, spoons or anything else that goes in the mouth. Depending on several factors, the bacteria can easily penetrate your enamel, grow rapidly or spread to multiple teeth. If the cavity is small, a tooth colored filling called a composite can be used to replace the diseased tooth structure.


The advantages of a composite are:

  • Conservative removal of decay
  • Better looking than silver fillings and come in a variety of shades
  • Quicker placement
  • Can last several years depending on size and hygiene
  • Can be used to fill cavities or repair small chipped teeth or pits


Some disadvantages are:

  • Can cause sensitivity to cold
  • Is commonly replaced after 5-7 years
  • Can stain
  • Is dependent on proper technique


How it's done

After the dentist numbs the area where the filling is to be placed, she will remove any decayed portions that are discolored or soft. After the tooth is prepared, a blue colored solution called etch is then applied to help clean the tooth and prepare it for bond which holds the filling in the tooth. The tooth colored filling is then applied in a putty form and then hardened with a blue light. Similar to the lights that harden acrylic nails at a nail salon. After the composite has hardened, the filling will be adjusted to your bite, smoothed and polished. It is important to Dr. Sing that you bite feels just right before you leave the office. If the bite is high for too long, hypersensitivity can occur. Call the office right away if you notice that a filling feels high.
