This is why your dentist takes x-rays. You can see by the photo that the teeth look fine. But when the radiograph is taken you can see an interproximal cavity in-between the teeth on the right side of this upper bicuspid tooth. The bacteria that eat your teeth Streptococcus mutans are facultative gram negative anaerobic bacteria that cannot live in oxygen which is why they grow best in-between the teeth where there is no air containing oxygen and can only be cleaned with dental floss. Did you floss today? When was the last time you had a dental exam that included x-rays?
