Root canal how does it work




















Once it has taken effect, a local anesthetic will be injected into your gums. You may feel a sharp pinch or a burning sensation, but this will pass quickly. When your tooth is numb, the endodontist or general dentist will make a small opening in the top of the tooth. Once the infected or damaged pulp is exposed, the specialist will carefully remove it using special tools called files. Once the pulp has been removed, the dentist may coat the area with a topical antibiotic to ensure that the infection is gone and to prevent reinfection.

Once the canals are cleaned and disinfected, the dentist will fill and seal the tooth with a sealer paste and rubber-like material called gutta-percha. They also may prescribe you oral antibiotics. The dentist will end the procedure by filling the small opening in the top of the tooth with a soft, temporary material.

This sealant helps prevent the canals from being damaged by saliva. Your tooth and gums might feel sore when the numbing medication wears off. Your gums may also swell. Most dentists will have you treat these symptoms with over-the-counter pain medications such as acetaminophen Tylenol or ibuprofen Advil.

Call your dentist if the pain becomes extreme or lasts for more than a few days. You should be able to resume your normal routine the day after the procedure. If you prefer, the dentist may place a permanent crown on the tooth. Slide show: Root canal treatment.

The premolars and back molar teeth chewing teeth have 2 or 3 roots, each containing either 1 or 2 root canals.

If the treatment needs to be carried out over several sessions, your dentist may put a small amount of medicine in the cleaned canal in between visits to kill any remaining bacteria. If you have symptoms from the infection, such as a raised temperature or large swelling, you may be given antibiotics to help manage and prevent further infection.

At your next visit, the temporary filling and medicine within the tooth is removed and the root canal filling will be inserted. Root-filled teeth are more likely to break than healthy unrestored teeth, so your dentist may suggest placing a crown on the tooth to protect it.

In some cases a root-filled tooth may darken, particularly if it's died as a result of injury like a knock to the tooth.

There are several ways your dentist can treat discolouration, such as whitening the tooth using chemicals. A crown is a cap that completely covers a real tooth. It might be necessary to use a crown after root canal treatment to prevent the tooth fracturing.

A mould of your tooth will be taken to ensure the crown is the right shape and size, and fits your tooth accurately. If there's only a small amount of tooth left after the root canal treatment, a post can be cemented in the root canal and used to help keep the crown in place.

One of the great fears about this kind of treatment is that it will be painful, but the treatment that is carried out by a trained dental surgeon should be relatively painless.

The pain that is felt comes from the infection and not from the treatment. The treatment does not cause pain; it helps to alleviate it. The dental surgeon will relieve the pain of the procedure by numbing the tooth and surrounding area with local anesthesia. After the treatment, some tenderness is normal. It is temporary, and over-the-counter OTC pain medication may be enough to relieve it. If needed, prescription drugs, such as codeine, are available.

The dentist may prescribe an antibiotic to treat or prevent infection. The bacteria will eventually destroy the pulp. If the bacteria penetrate through the root openings, it can cause an infection in the bone. An infection will weaken the bone and break it down. The ligaments around the tooth will swell, and the tooth will become loose.

A pulp injury will make the tooth sensitive to high and low temperatures. There may be pain when chewing, and some people have a continuous, throbbing pain. Without treatment, the infection will spread. Eventually, the tooth will become loose and need extracting.

Some patients opt for extraction, especially if it hurts a lot or if the tooth cannot be restored, for example, if there is large decay, trauma, or loss of bone due to periodontal, or gum, disease. However, removing a tooth may mean that the surrounding teeth start to move and become crooked.
