If you have a tooth that’s badly infected, it’s important to get it treated right away. Prompt treatment can relieve pain, stop infection from spreading and allow you to get back to your normal routine.

杜牙根 removes the infected tissue within a tooth and saves it from needing to be extracted. It’s a nonsurgical procedure that requires the dentist to drill into your tooth’s pulp chamber and root canals to clean them.

If the inside of your tooth is infected, a dentist can perform a 杜牙根 to save it. This treatment usually involves cleaning the tooth's pulp (the soft tissue inside a tooth).

The procedure begins with an injection of numbing medication into your gums. You may feel a pinch or a burning sensation when the anesthetic takes effect, but it will pass quickly.

During the treatment, the infected pulp is removed using small files and drills. The dentist then cleans, shapes and decontaminates the hollow area in the tooth. They will also use special irrigation solutions to flush away the infected material.

After a root canal is completed, the dentist will fill the empty space in the tooth with a rubber-like material called gutta percha. They will then cover the biting surface with a filling or crown to protect the tooth from breaking during future chewing.

Root canal therapy used to be painful, but dental advances and local anesthetics have made it much less uncomfortable. In most cases, the pain is minimal and goes away with a few days after the procedure. However, if you have a lot of pain or your treated tooth is still sensitive to hot or cold foods or drinks, contact your dentist for an evaluation and possible treatment.
Root Canal Treatment

Root canal treatment (endodontic therapy) is a dental procedure that removes infected or damaged tissue from inside the tooth’s core. This core, called the pulp, contains blood vessels and nerves that are essential for a tooth to survive.

If a tooth’s pulp becomes infected, this can lead to severe pain and swelling inside the mouth or jaw. This can also cause the tooth to crack, fall out or require tooth extraction.

To treat a painful or infected tooth, your dentist will first examine the affected area and take X-rays of the tooth to see how deep the infection is and where it’s located within the pulp. Next, the dentist will administer a local anesthetic to numb the area.

Once the area is numb, your dentist will remove the infected tissue and clean out the interior of the tooth. They will then place a rubber-like compound called gutta percha into the space and seal it off with a filling.

Once a tooth has had a root canal, it can usually last a long time as long as you take good care of it and keep up with regular dental exams. It is important to maintain proper oral hygiene and avoid consuming a lot of sugary foods.

When the pulp inside your tooth becomes infected or damaged, you may need root canal treatment to remove the infection and save your tooth. This procedure requires a visit to your dentist who numbs your mouth and makes an opening through the crown of the tooth into the pulp chamber, where the infected or unhealthy tissue is removed and the canals are cleaned and filled with a material that will prevent future infections. After the treatment, a dental crown will be placed to protect and restore your tooth. The procedure is usually quick and painless, but some people may experience discomfort after the treatment. If you are apprehensive about getting a root canal, talk to your dentist about the process before you make an appointment.
