What are the symptoms of pulpitis?

Sometimes the infection can spread to other parts of your body. If you have an abscess, the tooth is very painful and is sensitive to pressure or tapping with a dental tool.

How can dentists tell if I have pulpitis?

Dentists will check your tooth's pulp by:

  • Testing to see if your tooth is sensitive to hot, sweet, or cold things

  • Using an electric pulp tester to see if the pulp is alive

  • Tapping on your tooth to see if the nearby tissue hurts

  • Doing x-rays to see how far the problem has spread

How do dentists treat pulpitis?

For mild pulpitis, dentists will take out any decay and fill the cavities. Sometimes dentists use a temporary filling with pain medicine in it for 6 to 8 weeks before putting in a permanent one.

If the pulp is badly damaged and can't be healed, dentists will give you pain medicine and either:

  • Do a root canal to remove the pulp from your tooth and then fill and seal the tooth canal

  • Take out the tooth if it can't be saved

If you have an infection, they'll also give you antibiotics.
