Root canal treatment

The vast majority of root canal treatments are due to the fact that the nerve of the tooth is damaged, either in the form of an inflammation of the nerve or if the nerve after a blow to the tooth is exposed because the tooth is broken. In very sheep cases, a tooth must be rooted for another reason, for example, if the tooth needs a crown and there is very little tooth substance left.


Do I have pain from a tooth that needs root canal treatment?

Inflammation of the nerve of a tooth

You don't necessarily feel anything from a tooth that needs root treatment. Often it is only detected in connection with an X-ray at the dentist. However, the tooth can be sore when chewing, giving a throbbing or pulsating sensation. But

Inflammation of the bone around the tooth

symptoms may also be severe dacing when consuming cold or hot food or drink, swelling or outright tooth pain. If a tooth nerve has been dead for a long time, the color of the tooth can also be changed to darker.

An untreated inflammation of a tooth can spread to the bone around the tooth and eventually spread to the bloodstream. It's a potentially deadly condition. Fortunately, this is a very rare complication, but still makes us always recommend treating a tooth root infection. This even if there are no symptoms from the tooth or area. 


How to do a root canal treatment?

First part of root canal treatment - removal of nerve and inflammation of the tooth

A root canal treatment is typically done in two séances, every week. At the first séance, a hole is drilled down through the tooth into the root canal. After that, the inflamed nerve and bacteria can be removed. This part of the treatment ends with a drug in the root canal that disinfects the duct. This is done to remove any remaining bacteria. A temporary filling is laid over the hole in the tooth. After the first round of root canal treatment, you can be a little sore from the tooth. Occasionally, the treatment can be completed as early as this first treatment session.

Otherwise, treatment is continued at the second and final treatment. Here, the root canal is filled with a rubber material that fills the cavity. This means that no new bacteria can enter the tooth. When the root treatment itself is complete, the tooth is closed with a plastic filling. This filling can sometimes be the final restoration for the tooth. However, it is often recommended that the tooth be given a crown afterwards. This is done to make sure that the very weakened tooth does not split and therefore needs to be removed.

Kofferdam as protection

For a successful result of a root canal treatment, it is important that the treatment takes place without new bacteria coming from the oral cavity into the tooth. Therefore, all root canal treatments are carried out during shielding of the tooth with a rubber cloth called kofferdam. It uses sterile instruments and the root canal is purged with sterile disposable files. At the same time, we use an electronic technique to determine the length of the tooth root, this is a technique that is more accurate than simply taking X-rays of the tooth.
