A composite (tooth colored) filling is used to repair a tooth that is affected by decay, cracks, fractures, etc. The decayed or affected portion of the tooth will be removed and then filled with a composite filling.
As with most dental restorations, composite fillings are not permanent and may someday have to be replaced.
Reasons for composite fillings:
It is normal to experience sensitivity to hot and cold when composite fillings are first placed. However, this will subside shortly after your tooth acclimates to the new filling.
