Bacteria lives in our mouths and if not removed daily through proper brushing and flossing it can cause bone loss.
You may not see the bone loss as it can occur underneath the gum tissues. However, plague and tartar are present on the roots of the teeth and the gums become red and loose.
Once the bone has been destroyed it cannot grow back. But by removing the bacteria we can prevent the bone loss from becoming worse and hopefully prevent the loss of your teeth.
