How long does a root canal take? All information

How long does a root canal take: The root canal is the natural anatomical space inside the root of the tooth. It consists of a pulp chamber (within the crown of the tooth), the main canal, and more complex anatomical branches that can connect the root canals to each other or to the root surface.

Root canal treatment is a process of removing the damaged pulp, cleaning the inside of the root canal cleanly, filling the medicine with a lid to prevent bacteria from entering, then covering with a lid and ending. Will be opened.

It may seem easy to write like this, but in reality, the root canal has a complicated shape and is different for each person, so it is difficult to remove the pulp. If you leave even a little damaged pulp, the pain may not disappear even after the treatment, so you must treat it carefully.

After removing the pulp, it is necessary to clean the inside of the root canal as cleanly as possible. Careful cleaning of the intricate root canals is a very difficult task to avoid pain and swelling. Also, the accuracy of this procedure depends on whether the tooth can be left for a long period of time to function. In this article you can know, how long does a root canal take & additional information about root canal treatment.

Root canal treatment generally goes through two major steps, the first anti-inflammatory, the second root canal treatment, with a time interval of one week, if successful, it will be completed within a week. Sometimes it will be a little different depending on the individual’s specific situation or the doctor’s method, it may be 3 days apart, or it may be longer. If the tooth decay progresses too much, nerves will be infected and inflammation will occur. If that happens, you have to take measures to remove the nerves in your teeth.

In the process of root canal treatment, if it is anterior teeth, about 20 minutes each time, if it is posterior teeth, about 40 minutes each time, generally need to come to the hospital for follow-up after root canal surgery to ensure the recovery of teeth.

Root canal treatment is unlikely to be completed in a few hospital visits like general caries treatment. Since it requires very delicate operations as described above, please expect that it will take 3 to 4 weeks. If the root canal has a complicated morphology or a high degree of infection, it is not uncommon to require a treatment period of 2-3 months. Once the nerves are infected, it takes about 2 to 3 months to complete the treatment, although there are individual differences.

First, remove the inflamed nerves, put a medicine to remove the inflammation, and put on a temporary lid. Since it is difficult to completely get rid of nerves at once, the medicines are exchanged several times, and when inflammation disappears, the final medicines are put and the root canal treatment is completed.

However, the treatment is not over here, but this time we will restore the teeth to their original shape. This is the so-called false tooth condition.

The treatment is completed when the base is first laid, then the cover is modeled, and the finished product is attached. It will take about 2-3 months at the earliest to get your teeth back to their original condition, depending on the length and frequency of your visit and the degree of inflammation. If you do not complete the treatment properly, you may lose your important teeth, so be sure to attend to the treatment properly!

Symptoms & Causes of root canal Infection

It is important that seriously damaged or damaged teeth are treated as soon as possible. Untimely tooth treatment can lead to root canal infection. In our dentistry you can receive both preventive care and root canal treatment (endodontic treatment) of infected teeth.

Root canal infection includes an infection of the pulp located inside the tooth. When this flesh is infected, it can cause toothache and tooth abscesses. The spread of root canal infection can cause serious damage to the jawbone, gum tissue and adjacent teeth, so it is important to take control of the problem as soon as possible.

What causes root canal infections?

Bacteria are usually found in the mouth. Infections occur when tooth decay or tooth enamel and dentin damage allow bacteria to access the flesh inside the tooth. Common causes usually include poor oral hygiene and oral injuries.

Tooth sensitivity

Many people who start an infection will notice that their teeth are sensitive to hot and cold temperatures. Keep this in mind when enjoying food or drinks.

Pain and discomfort

Tooth sensitivity can develop into severe pain and discomfort. Many patients who come to our clinic complaining of a toothache find out that they suffer from a root canal infection.

Tenderness and swelling of the gums

As the tooth pulp infection worsens, this leads to swelling of the gum tissue around the tooth. Gum sensitivity is not uncommon for people with root canal infections.

Discoloration of the affected tooth

As the disease progresses, the tooth may become discolored. An infected tooth usually gets darker. Infection of the internal structures of the teeth usually leads to a darkening or yellowing of the external color of the tooth.

Chronic unpleasant breathing

Serious bad breath is not uncommon for people suffering from this disease. It can also be a sign of the development of a dental abscess. If you notice a combination of the above symptoms, you should contact your dentist as soon as possible.

Treatment of an infected tooth

When treating a root canal infection, it is important to remove the infected tooth pulp. The dentist then sterilizes and fills the pulp chamber to destroy all bacteria and control the infection. The treated tooth will be closed with a crown so that patients can bite and chew again.

Root canal treatment Procedure

Take X-ray film before surgery

The preoperative X-ray film reflects the objective conditions of the affected tooth and periodontal tissue: root canal length, periapical alveolar bone density, etc., which is the basis for the doctor’s treatment; the root canal preparation needs to be checked during the operation. For those with more difficulties, it is necessary to insert the needle and take X-rays while preparing the root canal to monitor the direction and degree of root canal preparation for good treatment effect; postoperative X-ray film is to test the two-dimensional effect of root canal filling Objective standards are essential. For special cases, long-term follow-up observation is required. In addition to the clinical manifestations of the patient, X-ray film is also an important observation indicator.

Uncover the medullary cavity

If there is pus, it should be that the pulp has been necrotic and has developed to the apex of the tooth, and it is a more serious stage. The first diagnosis should be aimed at “drainage” to alleviate the inflammation around the apical period. Stage treatment.

Determine the working length of the root canal

The parallel projection X-ray method and root canal length measuring instrument are used to determine the degree of root canal.

Root canal preparation

The purpose of root canal cleaning and shaping is to remove the infectious materials on the root canal wall, remove the infected dentin through the cutting action of root canal instruments and clean the root canal wall bacteria to facilitate root canal filling.

Root canal irrigation and disinfection

The purpose of root canal irrigation is to remove microorganisms, wash away residues, lubricate root canal instruments and dissolve organic residues. Then, sterilize the root canal again to make the root canal aseptic.

Root canal filling

Close the entire root canal system, block the main root canal and lateral auxiliary root canal outlets, and prevent microbial and liquid leakage. Either the lateral compression method or the vertical compression method, the root canal filling should be dense. After the root canal filling, there is no root canal cavity on the X-ray film, nor can it exceed the apical foramen.

Root canal piling

Due to excessive tooth defects, the strength of the teeth (performance to withstand strength) is greatly reduced, and it cannot well withstand the force of chewing. The purpose of piling is to increase the strength of the tooth root and crown, and increase the stability of the affected tooth.

Complete dental restoration

X-ray film showed that the root canal filling was intact, temporary or permanent tooth restoration was performed, and a crown was taken to protect the affected tooth. Root canal treatment can only be considered completed at this point, and follow-up visits are required after root canal treatment. The general cycle can be 3 months, half a year, 1 year, 2 years, or longer.

How to extend the life of teeth?

  • Use less treated teeth to bite harder food (the same is true for healthy teeth).
  • In order to prevent the filler from falling off, friends who have just finished filling their teeth should eat less sticky food as much as possible.
  • Brush your teeth carefully, use dental floss, and do a good job in oral cleaning.
  • Carry out regular oral health examinations and wash your teeth every six months or a year.

The problem of tooth life has a lot to do with your personal habits, treatment techniques, and whether or not crown restoration. There will not be any doctor who dare to pat the chest to ensure that I will use it for XX years. As long as you pay attention to the above points, the affected tooth can be used for a long time.

What to pay attention to after dental root canal treatment?

After the root canal treatment, it is best to use braces to reduce the chance of fracture and ultimately achieve the purpose of retaining your own teeth. If a small number of posterior teeth after root canal treatment are to be a single crown, as long as the remaining dentin is repaired enough, there is no need to make stakes, but if the posterior teeth after root canal treatment are to be used as the prop For teeth, no matter how much teeth are left, it is best to make piles. Before you do crown protection, you must pay attention to eating and maintain good oral hygiene. In addition to brushing your teeth, you will develop the habit of gargle after meals. After root canal treatment, the teeth will become brittle. Try not to use the affected teeth to chew too hard things, so as not to break the affected teeth; eat fewer sweet things and drink less carbonated drinks, which is very corrosive to the teeth.

How long does the tooth thus restored last?

The teeth or teeth treated and restored in this way can last a lifetime if cared for properly. The treated teeth can suffer cavities; therefore, it is essential to adopt good oral hygiene habits and go to regular dental exams to avoid future problems.

Since these treated teeth no longer have the pulp that kept them alive, they become brittle and more prone to fracture. This is important in deciding to place a crown instead of filling the tooth after root canal treatment.

To determine the success or failure of root treatment, the most reliable method is to compare new radiographs with those taken before treatment. This comparison will establish whether bone loss continues or if bone is regenerating.

Is a root canal painful?

The key thing to understand is that it is not the root canal therapy itself that causes the pain that many patients experience during the procedure. In fact, thanks to the progress made in anesthesia and surgical techniques, the discomfort experienced during a root canal therapy is no more intense than that of a filling.

Usually, to the point where surgery is required, the psychological feeling is more painful than experiencing the root canal surgery itself. Signs of pulp infection include swelling, sensitivity, and pain when biting and pressing.

In contrast, dental pain is usually caused by damaged and infected tissues, such as the dental pulp; root canal therapy solves this major problem by cleaning the affected area, stopping the infection and offering pain relief. The treated tooth and the surrounding area may be painful for a few days, but in this case the dentist will be able to prescribe drugs to relieve the symptoms and be able to return to normal almost immediately after the treatment.
