Cosmetic Fillings
There are alternative, natural-looking materials to conventional
silver-colored fillings – materials made from porcelain
and composite resins, which are colored to match natural
tooth enamel. Unfortunately, few materials can match the
strength and durability of dental amalgam and such, may need
more frequent replacement.
Common amalgam alternatives include:
Composite fillings -- As stated, composite fillings are
just what the name implies: a mixture of resins and fine
particles
designed to mimic the color of natural teeth. While not
as strong as dental amalgam, composite fillings provide
a pleasing
aesthetic alternative. Sometimes, composite resins need
to be cemented, or bonded to a tooth to allow for better
adhesion.
Ionomers -- Like composite resins, these materials are
tooth-colored. Ionomers are made from a combination of
various materials,
including ground glass and acrylic resins. Ionomers are
typically used for fillings near the gum line or tooth
root, where
biting pressure is not a factor. They are more fragile
than dental amalgam, however. A small amount of fluoride
is released
by these compounds in order to facilitate strengthened
enamel in the affected area.
Porcelain (ceramic) -- This material is usually a combination
of porcelain, glass powder and ceramic. Candidates for
porcelain fillings are typically crowns, veneers and
onlays and inlays.
Unlike ionomers, porcelain fillings are more durable
but can become fractured if exposed to prolonged biting
pressures.
