Depending on the circumstances, your dentist might recommend:
Desensitizing toothpaste. After several applications, desensitizing toothpaste can sometimes help block pain associated with sensitive teeth. There are a variety of products available over-the-counter. Ask your dentist which product might work best for you.
Fluoride. Your dentist might apply fluoride to the sensitive areas of your teeth to strengthen tooth enamel and reduce pain. He or she might also suggest the use of prescription fluoride at home, applied via a custom tray.
Desensitizing or bonding. Occasionally, exposed root surfaces can be treated by applying bonding resin to the sensitive root surfaces. A local anesthetic might be needed.
Surgical gum graft. If your tooth root has lost gum tissue, a small amount of gum tissue can be taken from elsewhere in your mouth and attached to the affected site. This can protect exposed roots and reduce sensitivity.
Root canal. If your sensitive teeth cause severe pain and other treatments aren’t effective, your dentist might recommend a root canal — a procedure used to treat problems in the tooth’s soft core (dental pulp). While this might seem like a significant treatment, it’s considered the most successful technique for eliminating tooth sensitivity.
