After decay is removed from a
tooth, something must be placed in that space to give strength
back to the tooth.
Inlays and onlays: In addition to fillings, lab fabricated
inlays and onlays are sometimes used. Although many patients
think of these as fillings as well, they are actually different
since they are laboratory fabricated.

White fillings: White fillings are an alternative
to silver (amalgam) fillings. White fillings are made
of a strong composite resin that is matched to the surrounding
tooth color. In the past, white fillings were placed
only on front teeth, but recently a stronger more durable
material has been developed that can withstand the chewing
pressure of back teeth.
White fillings are often preferable because:
- Cosmetic reasons
- Many patients prefer mercury-free fillings
- Patients with sensitivity
to heat or cold find metal-free fillings to be more
comfortable.

White Porcelain or Resin inlay or onlay: A porcelain
or resin inlay or onlay is used when the cavity
is too big for a filling, but isn't so big that a crown
is required. An inlay is a filling within the cusp tips
of the tooth. Onlays (also known as overlays) will overlay
one or more cusps in order to protect and strengthen the
tooth. |
| An inlay or onlay may also be made of gold. |
