Root canal treatment (also called a root canal) is done when decay will likely damage or has already killed a tooth. The dentist removes the pulp (including the nerve) from the tooth and fills the pulp cavity. This can prevent further painful infection in the pulp that may spread to other teeth. A root canal can also treat an infection that has developed into an abscess. This procedure can relieve toothache, stop infection, and promote healing.

•First, the dentist will numb your gums with a local anaesthetic.
•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.
•After the root canal, a permanent filling or crown is often needed. If a crown is needed, the dentist makes an impression of the tooth. A laboratory technician uses the impression to make a crown that perfectly matches your other teeth.
•The tooth may be fitted with a temporary crown until the permanent crown is made and cemented into place.

What To Expect After Root Canal Treatment

After a root canal, you may have throbbing pain, which you can treat with pain medication. The pain usually lasts only a day or two.


If you have an infected tooth, bacteria from the mouth can enter the bloodstream and cause infections in other parts of the body. Patients who struggle with fighting off infections, those who have had artificial joint replacements and those who have artificial heart valves, or were born with heart defects may need to take antibiotics before and after a root canal.
