Frequently Asked Questions
Root Canals
Teeth are composed of a hard structure surrounding a soft, living tissue called the pulp (also called the “nerve”). The pulp contains blood vessels, fibers and nerves. Endodontics (sometimes called “root canal treatment”) is the diagnosis and treatment of inflamed or diseased pulps.
Expand All | Collapse AllWhat are the symptoms of a root canal problem?
Some of the symptoms of a root canal problem include prolonged toothache when you have a hot or cold drink, unprovoked toothache, pain with chewing and pain when you lie down. A pair of sharp eyes, thorough clinical examination, an accurate electronic tooth vitality checker, and a clear radiograph are some of the criteria needed for an accurate diagnosis.
Why do I need root canal treatment?
Root canal treatment is usually carried out when there is a diseased pulp or infection in a tooth. The procedure is undertaken to retain the tooth that would otherwise require an extraction.
Why does the pulp become inflamed or diseased?
The main causes of pulp disease include tooth decay, previous treatment of tooth decay (e.g. deep fillings and crowns), cracked tooth and advanced gum disease.
How is root canal treatment done?
After the tooth is numb, an opening is made into the centre of the tooth. With small instruments, the pulp is sculpted and disinfected. A filling material is then inserted to the root canal space to prevent bacteria from entering the space.
Will the root canal treatment be painful?
Root canal treatment is usually carried out under local anesthesia so there is no pain during the treatment. However, it is essential to first diagnose that the tooth indeed needs root canal treatment.
Is there anything needed for the tooth after the root canal treatment?
Yes. To restore the missing or broken parts of the tooth, a foundation build-up is needed. Most teeth would require a crown to regain structural integrity and protect the remaining tooth structure after the root canal treatment is completed.
