A filling repairs and restores the surface of a tooth that has been damaged by decay, fracture, or wear.


Tooth whitening enhances the brightness of natural teeth; but it’s not for everyone. Discuss it with your Dentist before you take action.


Stay calm. Focus on stopping the bleeding and protecting the injured tooth or area by following the appropriate instructions in this section.
