Are Root Canals Painful?
The procedure normally causes no more discomfort that a filling would. Root canal treatment actually relieves the pain! Root canal treatment may have a bad reputation, but it is undeserved; in this case it's the disease that's to blame and not the cure. In other words, the infections that make the treatment necessary in the first place are often painful because they are inflamed tissue that has lots of nerves and therefore is very sensitive.
What is a Root Canal?
Dentists use the term “root canal” in referring to the tiny, narrow passageways that branch from a central, hollow space in your tooth (called the pulp chamber) down to the ends of the tooth roots. The term can also be used as a shorthand for “root canal treatment” — that is, the procedure used to save the tooth if the soft tissue deep inside of it (called pulp) becomes acutely inflamed or infected.
Why Do I Need a Root Canal?
If tooth pulp becomes acutely inflamed or infected because of decay or injury, the tissue will need to be removed in order to save the tooth and stop the infection from spreading.
Is There an Alternative?
You could have the whole tooth extracted, but it's always better to try to save it — especially since root canal treatment is routine and has a very high success rate (over 90%). Saving the tooth can prevent other troubles from occurring later on; these could include bite problems from teeth shifting position, difficulty eating, and loss of jawbone volume and density.
What Will Happen During the Procedure?
After numbing the area, a tiny hole in the crown (top) of your tooth is made to access the pulp chamber and canals. The diseased tissue is removed, and the pulp chamber and the canal(s) are disinfected all the way to the root end(s). Teeth in the front of the mouth have one root and generally one canal; back teeth have two or three roots and generally three or four canals. Those canals and the pulp chamber are filled with an inert, biocompatible material, and sealed with adhesive cement. The access hole will receive a temporary filling.
What Will Happen Afterwards?
Your tooth may feel sensitive for a few days, but any discomfort can usually be relieved with over-the-counter pain medication or anti-inflammatories like ibuprofen. You will be instructed to avoid chewing on that tooth until it receives its permanent filling, which can be placed a few days later. Depending on how damaged the tooth was to begin with, it may need a full-coverage crown. Those options will be discussed with you.
Sign and Symptoms of Root Canal Problems?
How do you know when you need a root canal? Sometimes, it's painfully obvious. If you feel constant and severe pain and pressure in your mouth, or noticeable swelling and extreme sensitivity in your gums, then it's clear you need an evaluation and treatment right away. Another telltale symptom of pulp tissue damage is sharp pain when you bite down on food. Lingering pain after eating hot or cold foods is also an indication of potential trouble. If you notice any of these symptoms, you need to have an examination as soon as possible.
How Can I Avoid the Need for a Root Canal in Future?
Keep your teeth decay-free by brushing and flossing every day. Eat a healthy diet low in sugar and avoid acidic beverages such as soda. Have regular professional cleanings and exams. And if you're active in sports, consider ordering a custom-made mouthguard to protect your teeth from injury.
