Posted on Apr 3, 2015 Gum disease is a common condition that often begins with plaque buildup around the gumline. Without treatment, unchecked periodontal disease can damage both teeth and gums and necessitate a root canal in Belmont or even tooth extraction.This video demonstrates how a dentist finds plaque. Plaque is not always easily detectable, as its light yellowish color may not stand out against tooth enamel. So to find plaque, a dentist might apply a special solution to the teeth that stains only this sticky substance. Then he can perform an extensive cleaning of the teeth to remove it. Even though plaque may not cause pain, its effects on oral health can be severe. To avoid needing extensive dental treatment such as a root canal, see your dentist at least twice a year.
