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.
There are many types of filling materials available, each with their own advantages and disadvantages. You and your dentist can discuss the best options for restoring your teeth. Composite fillings, along with amalgam fillings, are the most used today. Composite fillings are tooth colored and can be closely matched to the color of the existing teeth; thus, making them more suited to be used on the front teeth or the more visible areas.
As with most dental restorations, composite fillings are not permanent and may someday have to be replaced.
Composite fillings are usually placed in one appointment. While the tooth is numb, your dentist will remove decay as necessary. The space will then be thoroughly cleaned and carefully prepared before the new filling is placed. If the decay was near the nerve a special medication will be applied for added protection. The composite filling will then be placed, shaped and polished; restoring your tooth to its original shape and function.
It is normal to experience sensitivity to hot and cold when composite fillings are first placed, however this will subside after the tooth gets acclimated to the new filling.
