Fillings

Restoration of missing parts of single teeth (Fillings)

Silver amalgam has been used for about 160 years for tooth restoration. This alloy contains silver, tin, copper, zinc, and about 50 percent mercury. It has been a highly successful, but unsightly material. Use of mercury in the body has been criticized since its inception, but amalgam use is still supported strongly by the American Dental Association and other health groups worldwide. A few people in the overall population may be allergic to the elements in silver amalgam. However, you have several other options for restorations (fillings).

Your choices for restoration of missing parts of single teeth (Fillings):

  • Silver amalgam.

    Average longevity about 15 years, silver colored, low-moderate initial cost. Best used in small-to medium-sized restorations of posterior teeth (premolars and molars).

  • Gold inlays and onlays.

    Average longevity 20 years to life, gold colored, moderate to high initial cost. May be used in most locations where metal is not displayed to an objectionable level.

  • Resin (plastic) – direct (one-day appointment placement).

    Average longevity 10-15 years, tooth colored, moderate cost. Best used in small-to medium-sized restorations for any teeth. Considered at this time to be comparable to silver amalgam’s service potential.

  • Resin (plastic) – indirect (two-appointment placement).

    Average longevity (expected) 10-15 years, tooth colored, moderate to high initial cost. Best used in medium to large restorations for posterior teeth (premolars and molars).

  • Ceramic – indirect (two-appointment placement).

    Average longevity 10-15 years, tooth colored, moderate to high initial cost. Best used in moderate to large restorations for any teeth.
