Root canal / Root canal therapy
What does root canal therapy mean?
A root canal is a procedure that treats infection inside a tooth while preserving the natural structure whenever possible. Beneath the enamel and dentin lies soft tissue called the pulp, which contains nerves and blood vessels. When this area becomes inflamed or infected, treatment is needed to prevent further damage. Root canal therapy allows your dentist to remove the infection, clean the inside of the tooth, and restore its strength and function.
When might you need this type of treatment?
Several warning signs may indicate that the inner portion of a tooth is compromised. Ongoing sensitivity to hot or cold foods, lingering pain when biting, swelling near the gums, or tooth darkening are common symptoms. Deep cavities, cracks, or past dental trauma can allow bacteria to reach the pulp. If left untreated, the infection may spread to the surrounding bone and tissues. Root canal therapy helps stop the problem early and often prevents tooth loss.
What should you expect during the procedure?
Root canal treatment is typically completed in one or two visits, depending on the extent of the infection. First, the area is gently numbed to keep you comfortable. A small opening is made in the tooth, so the damaged pulp can be carefully removed. The inside space is then disinfected, shaped, and thoroughly cleaned. Afterward, the canals are sealed and filled to protect against future bacteria, and the tooth is prepared for restoration.
Will the procedure be uncomfortable?
Many people worry about pain, but modern root canal therapy is designed to be comfortable. Local anesthesia prevents discomfort during treatment, and most patients say the experience feels similar to getting a routine filling. In fact, the procedure often brings relief because it removes the source of infection that caused the pain in the first place.
How long can a treated tooth last?
With proper care, a tooth that has received a root canal can remain healthy and functional for many years, often a lifetime. Maintaining good brushing and flossing habits, along with regular dental checkups, helps protect the restored tooth. Follow-up visits allow your dentist to monitor healing and ensure everything remains stable. When supported by healthy gums and bone, the treated tooth can continue working just like your natural teeth.
Does the tooth require additional protection afterward?
Most treated teeth are strengthened with a custom crown to restore durability and appearance. After placement, simply maintain good oral hygiene and attend routine dental visits to keep the tooth protected.
