Dental fillings are used to treat a cavity. The decayed portion of the tooth is removed and cleaned then the dental filling is filled where the decayed portion was removed.
Fillings are also used to repair cracked or broken teeth and teeth that have been worn down.
When the tooth decay or fracture is so extensive that a direct restoration, such as filling with composite resin, would compromise the structural integrity of restored tooth or provide substandard opposition to occlusal (i.e., biting) forces, Inlay or Onlay is used.
An inlay or onlay is an indirect restoration (filling) consisting of a solid substance (such as gold, porcelain or less often a cured composite resin) fitted to a cavity in a tooth and cemented into place. This technique involves fabricating the restoration outside of the mouth using the dental impressions of the prepared tooth, rather than placing a soft filling into the prepared tooth before the material sets hard.
Inlay or onlay can be done in a single day in our clinic with CAD/CAM system.
