After decay
is removed from a tooth, something must be placed in that space
to give strength back to the tooth. Fillings
are the most common restorative procedure. Fillings can be silver
or white.
Silver
(amalgam) fillings: Silver fillings have been used reliably
for many years. Typically, silver fillings are placed on back teeth
(molars). They are an economical way of providing a lasting restoration
for most cavities. The material is specially
formulated to withstand years of chewing pressure.

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 most commonly used for:
- Cosmetic
reasons
- Patients
who prefer mercury-free fillings
- Patients
with sensitivity to heat or cold
- the composite resin doesn't conduct temperature changes as fast
