What are interproximal caries?

Cavities. Interproximal are cavities between the teeth. These are usually caused by lack of flossing.
Between teeth! These are cavities BETWEEN your teeth! I tell all my patients: before bedtime, after they brush their teeth(before they rinse their mouth) to FLOSS IMMEDIATELY ! Then rinse with water and go to sleep. This should prevent further development of Interproximal caries!!!!
