Bumps on My Teeth Near the Gumline

Posted by AllSmiles

Hello. I used to brush my teeth very roughly. As a result (I think), I have a lot of notches or bumps on my teeth along the gumline of my teeth. I put “I think” in parentheses because when I mentioned this to a friend of mine who is a dental hygienist, she said the bumps on my teeth are probably from TMJ. Is this true? Will these bumps cause more problems with my teeth, like stains and cavities? Will I eventually need dental crowns? How can I get rid of the bumps? Thank you. Miguel


Thank you for contacting Radiant Smiles in Rocky Hill about the bumps on your teeth.

What Causes Bumps on Your Teeth?

Recent studies show that biting stress or bruxism is the most likely cause of bumps or notches on your teeth near the gumline, as opposed to aggressive brushing. According to a dentalcare.com article on the clinical signs of bruxism, you or your dentist may notice the following:

  • Worn tooth edges
  • Tooth flexing that leaves scoops or notches
  • Chips
  • Breaks
  • Cracks
  • Fractures

Identifying the Cause of Bumps on Your Teeth

An experienced dentist can examine and x-ray your teeth to identify the cause of the notches or bumps on your teeth. Rather than using cosmetic dentistry immediately to cover the imperfections, the dentist will determine how to minimize them. Still, it is unlikely that you will need treatment as aggressive as dental crowns to conceal the bumps. If you grind or clench your teeth, the dentist will recommend a custom night guard to reduce the pressure and protect your teeth.

We recommend scheduling an appointment with a cosmetic dentist with advanced TMJ training to explore whether you grind your teeth. The dentist will also ask questions to determine if you have TMJ symptoms, including headaches, earaches, or jaw pain.
