Tooth decay can be prevented and sometimes even reversed with routine cleanings. Teeth that are showing early signs of decay can be treated with fluoride and composite fillings. A tooth that has become infected can still be salvaged with a root canal. Teeth that are badly decayed can be capped with a beautiful and natural-looking dental crown or resurfaced with dental veneers. As a last resort, teeth that are very badly decayed may be extracted and the function of your bite and smile can be restored with an implant or bridge. There are many treatment options available depending on your exact circumstances.
