Painless Dentistry (formerly Painful Dentistry) is a dentistry where The Simpsons have gone for their dentistry needs.
During "Last Exit to Springfield", Lisa receives braces from Dr. Wolfe, who is the assumed owner. Marge is saddened that they can no longer afford braces, as they no longer have a dental plan. Because of this, Lisa must get much cheaper braces which are not even stainless steel. Ralph Wiggum is the only other known customer.
