Silver Fillings (Amalgams)
- 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.
