What is Root Canal Treatment?
Root canal treatment is done when decay will likely damage or has already killed a tooth. During a root canal, a dentist or endodontist removes the pulp from the center of a tooth and fills the pulp cavity. This can prevent the development of a painful infection in the pulp that may spread to other teeth. A root canal can also treat an infection that has developed into an abscessed tooth. This procedure can relieve toothache, stop infection, and promote healing.
Procedure
1. Depending on severity of the case, the dentist may inject a local anesthetic that will completely numb the teeth, gums, tongue, and skin in that area. Sometimes nitrous oxide gas will be used to reduce pain and help you relax.
2. The dentist may separate the decayed tooth from the other teeth with a small sheet of rubber on a metal frame. This protective rubber sheet also helps stop liquid and tooth chips from entering your mouth and throat.
3. The dentist will use a drill and other tools to remove the pulp from the tooth and will fill the inside part of the tooth below the gum line with medicines, temporary filling materials, and a final root canal filling.
4. After the root canal, a permanent filling or crown (cap) is often needed. If a crown is needed, the dentist removes the decay, and then makes an impression of the tooth. A technician uses the impression to make a crown that perfectly matches the drilled tooth. The tooth may be fitted with a temporary crown until the permanent crown is made and cemented into place.
What To Expect After Surgery
After a root canal, your lips and gums may remain numb for a few hours until the anesthetic wears off. Later you may have throbbing pain, which you can treat with pain medicines, such as ibuprofen, acetaminophen, or a stronger prescription painkiller. The pain usually lasts only a day or two.
Crowns that seal the top of the tooth and strengthen it may come loose over time. They may need to be repaired, redone, or cemented on again.
