What is the general sequence of a root canal procedure?
First, the canals must be shaped. The dentist will use tiny instruments to shape the canals, so they will be ready to receive the filling material. Once shaped, the canals are cleaned a second time. Filling the canals The dentist will use gutta-percha to fill the canals. This rubber-like material is placed inside the canals and then heated.

What is root canal treatment?
Root canal treatment is one type of endodontic treatment. To understand endodontic treatment, it helps to know something about the anatomy of the tooth. Inside the tooth, under the white enamel and a hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves and connective tissue and creates ...
How many appointments are needed for a root canal?
Most root canals can be done in one to two appointments. The first appointment is the procedure itself when the infected pulp is removed. The second (and maybe third) appointment is when the root canal gets cleaned and filled with a crown or other filling to prevent infections.
How do you know if you need a root canal?
There are a few symptoms that mean you might need a root canal—. Severe pain while chewing or biting. Pimples on the gums. A chipped or cracked tooth. Lingering sensitivity to hot or cold, even after the sensation has been removed. Swollen or tender gums. Deep decay or darkening of the gums.
What is the material used to fill a root canal?
After space is cleaned and shaped, the endodontist fills the root canals with a biocompatible material, usually a rubber-like material called gutta-percha. The gutta-percha is placed with an adhesive cement to ensure complete sealing of the root canals. In most cases, a temporary filling is placed to close the opening.
What to eat after a root canal?
After a root canal, try to eat soft foods that require very little chewing, like applesauce, yogurt, eggs, and fish. Avoid hard or hot foods that might hurt your teeth. Some dentists suggest to not eat for a few hours until the numbness in your mouth wears off so you don’t bite your cheek or tongue.
Does a root canal kill a tooth?
A root canal does not kill the tooth, and after a root canal is complete, the tooth will be able to function as it normally does. However, root canals do remove the nerves inside the tooth, but these nerves serve very little function in a fully formed tooth.
Do you need a crown after a root canal?
Needing a crown after a root canal depends highly on the location of the tooth in the mouth—teeth towards the back of the mouth like molars and premolars are needed more for chewing, and generally require crowns, where incisors or canines which aren’t needed for chewing don’t always require crowns.
What is root canal treatment?
Root canal treatment (also known as endodontic therapy, endodontic treatment, or root canal therapy) is a treatment sequence for the infected pulp of a tooth which is intended to result in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion. Root canals, and their associated pulp chamber, are ...
What is the filling material for a root canal?
Filling the root canal. The standard filling material is gutta-percha, a natural polymer prepared from latex from the percha tree ( Palaquium gutta ). The standard endodontic technique involves inserting a gutta-percha cone (a "point") into the cleaned-out root canal along with a sealing cement.
Why use rubber dams?
The use of a rubber dam for tooth isolation is mandatory in endodontic treatment for several reasons: 1 It provides an aseptic operating field, isolating the tooth from oral and salivary contamination. Root canal contamination with saliva introduces new microorganisms to the root canal which compromise the prognosis. 2 It facilitates the use of the strong medicaments necessary to clean the root canal system. 3 It protects the patient from the inhalation or ingestion of endodontic instruments.
What is endodontic therapy?
Endodontic therapy involves the removal of these structures, disinfection and the subsequent shaping, cleaning, and decontamination of the hollows with small files and irrigating solutions, and the obturation (filling) of the decontaminated canals.
How to treat irreversible pulpitis?
Treatment options for an irreversibly inflamed pulp (irreversible pulpitis) include either extraction of the tooth or removal of the pulp . Removing the infected/inflamed pulpal tissue enables the endodontist to help preserve the longevity and function of the tooth.
What is pulpectomy?
In the situation that a tooth is considered so threatened (because of decay, cracking, etc.) that future infection is considered likely or inevitable, a pulpectomy (removal of the pulp tissue) is advisable to prevent such infection.
How to save a tooth from infection?
To cure the infection and save the tooth, the dentist drills into the pulp chamber and removes the infected pulp. To get freedom of bacteria the use of efficient antiseptics and disinfectants is necessary. One of the most effective is N2 root canal material which contains a small dose of paraformaldehyde.
What is a small access hole in a tooth?
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.
What is the purpose of a temporary filling?
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.
What is a dental dam?
A dental dam — a thin sheet of rubber or vinyl — 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 canal treatment to be carried out in a sterile environment free from contamination by bacteria found in saliva ...
Can a tooth be saved if it has a pulp?
Preliminary treatment to remove the decay and the source of infection of the pulp is necessary, along with a determination of whether the lost tooth structure can be restored. If a fracture of the tooth has reached the pulp, or infection is associated with gum disease, it could be more difficult, if not impossible, to save the tooth.
Overview
Treatment procedure
The procedure is often complicated, depending on circumstances, and may involve multiple visits over a period of weeks.
Before endodontic therapy is carried out, a correct diagnosis of the dental pulp and the surrounding periapical tissues is required. This allows the endodontist to choose the most appropriate treatment option, allowing preservation and longevity of the tooth and surrounding ti…
Instruments and equipment used
Since 2000 there have been great innovations in the art and science of root canal therapy. Dentists now must be educated on the current concepts in order to optimally perform a root canal procedure. Root canal therapy has become more automated and can be performed faster thanks in part to machine-driven rotary technology and more advanced root canal filling methods. Many root canal procedures are done in one dental visit which may last for around 1–2 hours. Newer t…
Complications
Instruments may separate (break) during root canal treatment, meaning a portion of the metal file used during the procedure remains inside the tooth. The file segment may be left behind if an acceptable level of cleaning and shaping has already been completed and attempting to remove the segment would risk damage to the tooth. While potentially disconcerting to the patient, having metal inside of a tooth is relatively common, such as with metal posts, amalgam fillings, gold cr…
Outcome and prognosis
Root-canal-treated teeth may fail to heal—for example, if the dentist does not find, clean and fill all of the root canals within a tooth. On a maxillary molar, there is more than a 50% chance that the tooth has four canals instead of just three, but the fourth canal, often called a "mesio-buccal 2", tends to be very difficult to see and often requires special instruments and magnification in order to see it (most commonly found in first maxillary molars; studies have shown an average of 76…
Systemic issues
An infected tooth may endanger other parts of the body. People with special vulnerabilities, such as a recent prosthetic joint replacement, an unrepaired congenital heart defect, or immunocompromisation, may need to take antibiotics to protect from infection spreading during dental procedures. The American Dental Association(ADA) asserts that any risks can be adequately c…
Alternatives
The alternatives to root canal therapy include no treatment or tooth extraction. Following tooth extraction, options for prosthetic replacement may include dental implants, a fixed partial denture (commonly referred to as a 'bridge'), or a removable denture. There are risks to forgoing treatment, including pain, infection and the possibility of worsening dental infection such that the tooth will become irreparable (root canal treatment will not be successful, often due to excessive loss of t…
