Cavities between teeth (interproximal cavities) are caused by plaque buildup where brushing cannot reach. They often develop silently and require professional dental treatment such as fillings. Daily flossing and regular dental checkups are essential to prevent cavities between teeth.

Cavities between teeth—also known as interproximal cavities—are one of the most common dental problems we treat at Dent Blanche Dental. These cavities develop in the tight spaces between teeth where toothbrush bristles cannot reach.

Cavities Between Teeth: Causes & Treatment

What Is a Cavity Between Teeth?

A cavity between two teeth forms when bacteria break down enamel in the contact area between adjacent teeth.
