Silver fillings, otherwise known as Amalgams, are
an alloy of several metals ( Silver, Zinc, Tin etc. ) and Mercury. Once
mixed, they make up dental amalgam. This restoration has been used successively
for many, many years and has stood the test of time. Periodically, reports
are generated about the possibility of mercury toxicity from old existing
silver fillings. To date, it is the opinion of the American Dental Association
that there is no substantial proof that dental amalgam poses any threat
to the safety of the dental public.
Initially, the decayed tooth is excavated and all
the decay is removed.
The tooth is then shaped in a specific manner in
order to accept a silver filling.
Finally, a band is placed around your tooth and the
amalgam is condensed into the prepared tooth. The final filling is then
carved and adjusted to your bite.
Once placed, it takes almost two (2) weeks for your
new filling to become fully hardened. You may, however, safely chew
on it after twenty-four (24) hours.But, please, chew carefully
!
New silver fillings can be sensitive to hot and cold
liquids and other foods for the first four to six weeks or in some special
cases, even longer. If the sensitivity should continue for an extended
period of time or if the discomfort is extreme, call your dentist so
that he/she can evaluate the situation and prescribe the appropriate
therapy.
Sometimes, due to the effects of the local anesthesia,
it is quite difficult to make sure that your bite is exactly right.
If you feel any discomfort in chewing, call your dentist. A minor adjustment
is usually all it takes to make you comfortable. Don't wait too long!
Teeth can become quite sensitive if the bite is " high ".
You can generate in excess of 40,000 pounds per square inch when chewing
on your back teeth. Fillings which have not had the appropriate amount
of time to harden, or are " high ", cannot stand this kind
of pressure and may break.
