Interproximal cavities, more popularly known as the cavities in between your teeth, are actually pretty common. They start to form when there is a breakdown of the outer, calcified enamel of the tooth that is caused by bacteria in your mouth.

What causes interproximal cavities?

A cavity between two teeth is called an interproximal cavity. Just like any other cavity, interproximal cavities form when enamel is worn away and bacteria sticks to the tooth and causes decay.

How do you get rid of interproximal cavities?

When detected at an early stage, interproximal cavities can be recalcified with fluoride gel – only if the cavity has reached halfway into the enamel of the tooth. If the interproximal cavity is much deeper than that, your dentist may choose to fill the affected tooth.
