Interproximal

Interproximal describes the area or surfaces between adjacent teeth, commonly called the contacts or spaces where teeth touch. These interproximal areas are prone to plaque accumulation and are often harder to clean with a toothbrush alone, making them a common site for cavities and gum inflammation if not cleaned properly.

Dental professionals examine interproximal surfaces when checking for decay, assessing gum health, and planning restorations or orthodontic treatment, since fillings, crowns, bridges, or interproximal reduction can change how teeth contact one another. Regular interdental cleaning with floss or interdental brushes, combined with routine dental check-ups, helps keep interproximal areas healthy and reduces the risk of decay and periodontal problems.
