Once you’ve found the problem, there are things your dentist can use to help ease your pain, including: Toothpaste for sensitive teeth; Fluoride gel; Fillings that cover exposed roots; Sealants; Desensitizing pastes (not used with a toothbrush) you can get from your dentist; If your case is serious, your dentist might suggest a root canal. It’s also important not to shy away from dental care because of tooth pain. Ignoring your teeth can make things worse. Brush and floss twice a day to help keep your smile bright and pain-free.
