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.
