Root canals treatment is a dental procedure needed when the blood or nerve supply of the tooth (known as the pulp) is infected through decay or injury. If the pulp becomes infected, the infection may spread through the root canal system of the tooth. This may eventually lead to an abscess. If root canal treatment (RCT) is not carried out, the infection will spread and the tooth may need to be taken out.
A root canals treatment doesn´t hurt. In some cases a local anaesthesia is used. Also we offer specialized sedation for a root canals treatment. This sedation dentistyr allows to our doctors to provide a root canals procedure safely and comfortably for patients who experience anxiety when visiting the dentist.
Root Canals. The procedure.
A root canals treatment has as aim to remove all infection from the root canal. The root is then cleaned and filled to prevent any further infection. Root canals treatment is a skilled and time-consuming procedure. Most courses of treatment will involve two or more visits to your dentist. The secuence of a root canals procedure is as fallows:
Local anaesthesia: Applied to numb the tooth to be treated and the surrounding tissues.
Dental Dam: A dental dam will be placed over the affected and adjacent teeth. The tooth undergoing treatment protrudes through a hole punched in the dam, isolating it from the rest of the mouth. This allows the root canals treatment to be carried out in a sterile environment free from contamination by bacteria found in saliva or the rest of the mouth. A small access hole is drilled through the biting surface of an affected back tooth or from behind a front tooth, allowing access to the pulp chamber and root canals for treatment.
Remove the diseased and dead pulp: is removed from the tooth with specially designed instruments used to clean out the root canals and pulp chamber. This is not painful; the area is numb and the tissue being removed is either dead or dying. Once the pulp, along with the nerves contained in it, is removed, the tooth itself can no longer feel pain. The canals are disinfected with antiseptic and antibacterial solutions.
Fillings and sealers: The canals are then shaped with tiny flexible instruments to allow them to receive root canal fillings and sealers. The canals are washed and cleaned again to remove root canal debris prior to sealing them. Root canal fillings are selected that will exactly fit into the freshly prepared canals. Usually a rubber-like material called gutta-percha is used to fill the canal space. It is a thermoplastic material (“thermo” – heat; “plastic” – to shape), which literally is heated and then compressed into and against the walls of the root canals to seal them. Together with adhesive cement called a sealer, the gutta-percha fills the prepared canal space. Sealing the canals is critically important to prevent them from becoming reinfected with bacteria. A temporary or permanent filling material will then be placed to seal the access hole that was made to treat the canals, and the dental dam is removed. If the tooth lacks sufficient structure to hold a restoration (filling) in place, the dentist or endodontist may place a post (either metal or a very strong plastic) in one of the canals inside the tooth to help retain it.
After the procedure: An antibiotic may be prescribed to treat or prevent infection. Be sure to follow the instructions of your dentist or endodontist carefully. After-effects of treatment are minimal, generally lasting from a couple of days to about a week. It is normal to have some minor discomfort after treatment including slight soreness that can usually be managed with over-the-counter (aspirin, ibuprofen) medications or prescription (codeine-type) drugs, or a combination of the two.
Permant Restoration (Dental Crowns):Your tooth will need a permanent restoration — a filling or a dental crown — to replace lost tooth structure, and provide a complete seal to the top of the tooth. Your endodontist will send you back to your prosthodontist to determine which type of restoration is best for you. This step is of particular importance since many studies show that if the filled root canals are recontaminated with bacteria from the mouth, there could be a recurrence of infection around the tooth.
