Where in the mouth do cavities often develop?

Dr. Jeanne Morrison, PhD
Family Practitioner

Cavities will most likely develop in your back molars and premolars. This is a common location for cavities because the pits and grooves of your back teeth are harder to reach with a toothbrush. If these teeth cannot be properly cleaned, food is more likely to get stuck and plaque builds up. Cavities are more likely to occur because the bacteria are allowed to produce the acid that decays your tooth.

Cavities typically occur where the gums and teeth come together. Recession of the gums away from the teeth, combined with an increased incidence of gum disease, can expose tooth roots to plaque.

They are also common in the back teeth, as these can be tougher to keep clean when brushing and are then prone to plaque buildup.
