Even if you're absolutely scrupulous about daily flossing and brushing after you eat, plaque and tartar have a tendency to build up on your teeth over time. Plaque is a bacterial film, which calcifies into tartar if it's not removed. The presence of tartar can mobilize your body's immune system, which is why your gums become red and inflamed when you have a lot of it. This inflammatory response can actually lead to the destruction of gum tissue and the underlying bone if the tartar isn't removed through teeth cleanings. Regular cleanings and yearly X-rays
give us the opportunity to check on the health of those parts of your teeth that lie under the gums.
