A new tooth cuts through the gums when it grows into the mouth. Germs can easily go under the gums in that place and cause an infection. When the opposite tooth bites against the sore gum it can make an infection worse.

  • Toothache at the back of the jaw.
  • Mouth cannot open properly.
  • A bad taste coming from the back of the mouth.
  • Sore throat.
  • Skin over the new tooth is sore and hurts when you touch it.
  • The age of the person is the right age for growing a new molar tooth.
a new tooth at the back of the mouth.
Infection in the gums and pressure from the new tooth are painful. Notice the 'flap' of skin over the new tooth.

Do not take out a new tooth while there is still infection and pain. Wait for the infection to finish. Then decide if there is room for the tooth to grow in. A dental X-ray can help you make that decision. New molar teeth are often difficult to take out. Ask an experienced dental worker to take out the tooth, if it must be done.

What you can do

First, treat the infection. Then wait for the new tooth to grow more into the mouth. Tell the person what is happening. Tell him what he can do to keep the gums healthy while the tooth grows in:

  • Rinse the area with warm salt water. Make 4 cups each day until the mouth opens normally again. Then make 1 cup each day to prevent the problem from returning. Keep rinsing this way until the tooth grows all the way in.
  • Hold a warm wet cloth against the jaw as often as possible each day.
  • Take aspirin for pain.

Give penicillin if there is fever, a swelling, or if he is only able to open his mouth a little.
