After the procedure, an antibiotic may be prescribed to treat or prevent infection. It is normal to have some minor pain or discomfort after treatment including slight soreness on/around the treated tooth that can usually be managed with over-the-counter (aspirin, ibuprofen) medications or prescription (codeine-type) drugs, or a combination of the two.

Also please refrain from biting any hard or solid foods on the treated tooth for a couple of days after treatment. After-effects of treatment are minimal, generally lasting from a couple of days to about a week.

Your tooth will need a permanent restoration — a filling or a crown — to replace lost tooth structure, and provide a complete seal to the top of the tooth.

You can still get a cavity or gum disease after a root canal treatment. Root canal treatment does not protect your tooth from other types of damage. With proper care and regular dental visits, the tooth could last as long as your other teeth. Most of the time, a tooth that has had a root canal treatment can be saved. However, there are cases where everything possible has been done to save a tooth and still the tooth must be extracted (pulled).

Be sure to follow the instructions of your dentist or endodontist carefully.
