Symptoms that indicate the need for endodontics treatment:

Root canal treatment method

Root canal treatment requires one or more treatment sessions
.Moreover, it can be done by a dentist or an endodontist in a dental clinic. Choosing the type of dentist depends on the type and severity of the root canal problem.
An endodontist is a dentist who specializes in the causes, diagnosis,
Prevention and treatment of dental pulp diseases and injuries.

Root canal:

The first step in this procedure is to take an X-ray to see the shape of the root canals and determine if there are signs of infection in the surrounding bone.

The dentist or endodontist will use local anesthesia near the tooth.

Anesthesia may not be necessary because the nerve is dead
However, most dentists do it to make the patient calmer and more comfortable.

At this stage, to keep the area dry during the treatment,
Your dentist will place a rubber dam (a sheet of rubber) around the tooth.

Then a hole is created to access the tooth.
The pulp is removed from the tooth along with bacteria and associated debris.
This process is done using root canal cleaning files.

The dentist inserts files with different diameters into the root canal and drains the entire length of the tooth root canal.

Once the tooth is thoroughly cleaned, the canals need to be sealed.

Some dentists wait a week for the tooth infection to disappear completely
Moreover, some may clean the tooth on the same day.

If the root canal treatment is not completed on the same day, A temporary dressing is placed in the outer hole of the tooth to prevent infection.

and to fill the outer part of the tooth created at the beginning of the treatment, It is filled with amalgam or composite.

In the final stage of tooth restoration, Due to extensive destruction, the need for extensive fillings, and sometimes due to the absence of tooth walls and weakened teeth Post & Core or cover is used.

For the first few days after treatment, The tooth may be sensitive due to inflammation of the natural tissue. Especially if you have pain or infection before endodontics treatment.

This sensitivity or discomfort is usually controlled with pain relievers such as ibuprofen or naproxen.

Complications of root canal treatment

New infections may develop despite the dentist’s efforts to clean and seal the tooth.

Among the possible reasons for this are:

  • There are more than the average number of root canals in the tooth, and one of them is not denervated
  • Invisible fracture and detection in the root of the tooth
  • Inadequate tooth restoration allows bacteria to enter the inner parts of the tooth and infect that area
  • Decomposition of the materials used in sealing (closing) the root eventually causes re-infection.

Re-endodontic treatment (RE-ENDO) can be successful.

Sometimes, the endodontist will try to save the tooth, the most common surgical procedure being an apicectomy or root removal.

This procedure relieves inflammation or infection in the bony area around the end of the tooth.

In this procedure, the gum tissue is opened, the infected tissue is removed, and sometimes the end of the root is removed.

An alternative to root canal treatment

Your teeth allow you to eat various foods to maintain proper nutrition.
Root canal treatment is a good choice of treatment to save teeth. The only alternative to the root canal method is tooth extraction.

After extraction, the tooth can be replaced with a bridge, implant, or removable prosthesis to restore chewing function and prevent the change of adjacent teeth. These options are not only more expensive than root canal treatment. Instead, they need more time for treatment and additional methods for adjacent teeth and tissue support.

Since some reasons include:

  • extensive tooth restoration,
  • Multiple treatments on a tooth and extensive decay of the dental pulp cause inflammation and infection.
  • Maintaining oral and dental hygiene ( brushing twice a day, Using antiseptic mouthwash at least once a day, and scheduling regular dental visits)
    It may reduce the need for a root canal procedure.

In order for the teeth not to face problems and damage, and to ensure the health and beauty of the teeth, observe the following points:

  • Keeping teeth clean (including using dental floss and toothbrush)
  • Not consuming too much sweet food
  • Quit smoking if you smoke
  • Do not crush nuts and hard materials like these with your teeth.

Is it possible to treat tooth root infections at home?

Tooth infection is not a problem that can be solved at home with home remedies. Therefore, it is better to avoid home remedies and try methods that may be dangerous. Instead, it is better to see a dentist or an endodontist.

However, if we do not have access to a dentist at the moment, the following instructions can be followed to remove some of the symptoms of tooth root infection:

  • Taking over-the-counter pain relievers such as ibuprofen or acetaminophen to relieve the pain of a root infection.
  • Rinsing the mouth with lukewarm salt water (it is better to do this slowly without putting extra pressure on the teeth and gums).
  • Avoid very hot or cold foods and drinks (as much as possible).
  • Chewing food with the opposite side of the infected tooth.
  • Brushing teeth with soft-bristled toothbrushes.
