Root canal therapy is a dental treatment that saves teeth from being extracted. When the pulp inside a tooth becomes infected or dies, root canal therapy removes the infected tissue and replaces it with a rubber-like material. This restores the health of the tooth and prevents infection from spreading to other parts of the body. However, this treatment can come with many complications. 

Complications of Root canal therapy

The most common complication associated with Root canal therapy is failure to properly clean and fill the root canal, which can lead to re-infection and the need for repeat treatment. Other potential complications include:

a)Instrument fracture 

Instrument fracture during root canal therapy is a rare but potential complication that can occur. It can cause extensive damage to the tooth and may require extraction. Although it is a rare complication, it is important to be aware of the risks and take necessary precautions to avoid it.

There are several factors that can contribute to instrument fracture during root canal therapy. One is the type of instrument being used. Another is the level of experience of the dentist or endodontist performing the procedure. And finally, the condition of the tooth being treated can also play a role.

Instrument fracture during root canal therapy can happen with both hand files and rotary instruments. The most common type of instrument to fracture is the rotary file. This is because they are used more often and are under more pressure during the procedure.

There are several ways to avoid instrument fracture during root canal therapy. One is to use only hand files when possible. Another is to use rotary instruments with a lower speed setting. And finally, be sure to use only high-quality instruments that are designed for root canal therapy.

If instrument fracture does occur, it is important to take action immediately. The first thing to do is stop using the instrument that fractured. Then, remove all of the debris from the tooth and assess the damage. If the tooth is severely damaged, it may need to be extracted.

b) Sodium hypochlorite accident– 

Sodium hypochlorite is used as an irrigant and disinfectant during root canal therapy, but it can also cause chemical burns to the gums if it accidentally comes into contact with them. Symptoms of a sodium hypochlorite burn include pain, redness, swelling and blistering. 

Treatment for a sodium hypochlorite burn may involve cleaning the wound, applying a topical antibiotic ointment and/or taking oral antibiotics. In severe cases, surgery may be necessary to remove damaged tissue.

c)Tooth discoloration after root canal therapy

While most people who undergo this procedure experience little to no problems, a small percentage can develop tooth discoloration as a side effect. This can be due to many different factors, such as the type of material used to fill the root canal, the age of the patient, and even their diet. If you are experiencing tooth discoloration after a root canal, be sure to consult with your dentist to find out if there is anything that can be done to correct it.

While tooth discoloration is not a serious medical condition, it can be unsightly and embarrassing. If you are concerned about the way your teeth look, be sure to talk to your dentist. They will be able to advise you on the best course of action to take. In most cases, tooth discoloration can be corrected with a simple whitening procedure. However, in some cases, more aggressive treatment may be necessary. Regardless of the cause of your tooth discoloration, there is likely a treatment option that can help you achieve the results you desire.

d)Poor quality root canal filling

Poor quality root canal fillings can lead to a number of problems, including infection, pain, and even tooth loss. If you are experiencing any of these issues, it is important to seek treatment as soon as possible. A poor quality root canal filling can be replaced with a new one that will restore the health and function of your tooth.
