Why do cavities often occur in the back teeth?

American Dental Association answered:Tooth decay often occurs on the chewing surfaces of the back teeth. These surfaces have pits and grooves that trap plaque, bacteria and bits of food. The pits and grooves are hard to keep clean, because toothbrush bristles cannot reach into them.

Dr. Peggy Rosen answered:Cavities often occur in the back teeth because:
- Back teeth are being used during chewing; the chewing surfaces of back teeth have pits, grooves that can trap foods inside causing cavities at the top of the teeth
- Foods trap inside the gap between two teeth in the back causing cavities at the side of the teeth
- Improper flossing to remove foods between the teeth in the back
