A cavity that is not filled grows bigger and deeper until it touches the nerve. Germs travel inside the tooth’s root and start an infection called an abscess. Pus forms at the end of the root, inside the bone. As the pus increases, it causes great pressure. This is why an abscess causes severe pain.  Signs:
Treatment:If there is no swelling, take out the tooth immediately (unless you are able to give root canal treatment). This allows the pus to escape and relieves the pain. See Chapter 11. If there is swelling, treat the swelling first. Take out the tooth only after the swelling goes down. This is necessary because an anesthetic (see Chapter 9) will not work if there is swelling. To treat the swelling, give an antibiotic. Penicillin by mouth is best. Use an injection only when the person is in immediate danger. For example, inject penicillin when the person has a fever or if the swelling is pressing against the throat. But remember you can treat most serious infections with simple penicillin by mouth. For the doses for serious infections, look at the box below. If you still think an injection is necessary, look at the section on procaine penicillin. Adults and children over 25 kg (60 pounds) of weight should take the same amount of oral penicillin. Children under 25 kg should take ½ as much. For most infections, penicillin by mouth is taken 4 times a day for 10 days. The person should take all of the penicillin, even if the pain or swelling goes down. See below for the correct doses.
For serious infections, it may be necessary to double the doses shown in the table and paragraph above. If the infection does not heal, you may need a different medicine. Usually you can take out the tooth 1 or 2 days before the end of the antibiotic treatment, but the person must continue to take all of the tablets, even after you have taken out the tooth. If not, the infection might come back even stronger than before. If the swelling is ‘pointing,’ open it with a sharp sterile knife to release the pus. Cover the wound with a sterile dressing to keep it clean. If you are not able to do that, explain how to reduce the swelling with heat. As often as possible until the swelling goes away:
