Dental overhang

What are the symptoms of an overhang?

Overhangs occur when a filling is not placed flush with the tooth surface.
These extensions create areas that collect plaque bacteria.
The overhanging filling prevents the tooth being cleaned effectively, as it catches the floss, and makes brushing that area almost impossible.

Overhangs can be created not only from fillings, but from poorly fitted crowns, veneers or excess of dental cement. It is important to have the excess of dental material removed to prevent further damage to the tooth or the supporting bone from decay or gum disease.
