Can you tell me if a tooth gets pulled do others start falling out ?

Depends: Are the other teeth suffering from periodontal disease? If left untreated, periodontal problems compromise the bony support and the teeth will need extraction.

Tooth removal: If you have one tooth removed the neighboring teeth may shift position because they loose support. If the reason the tooth was removed was because of periodontal disease and poor bone support, then other teeth teeth with bone loss may be lost soon. It is best to have this discussion with your dentist so you can get your mouth back to a healthy condition.
