Frequently Asked Questions About Root Canal Therapy

Question: How do I know if I need endodontic treatment?

Answer: We typically recommend this procedure should a tooth become infected or develop a dental abscess. Common warning signs include toothaches, tooth sensitivity to hot or cold temperatures, a fever, swelling around the tooth, and pain when biting down or chewing. If you encounter one or combination of these symptoms, then you should schedule a consultation right away for a diagnosis.

Question: What does the treatment involve?

Answer: After numbing the area with a local anesthetic, we will carefully open the tooth. We can then remove the infected tissue from the tooth and root canals. We will then place a restorative filling known as gutta percha into the tooth. We will then complete the procedure by placing a dental crown.

Question: How will my tooth look after the procedure?

Answer: By placing a dental crown, we ensure your tooth looks and functions naturally. The crown fits over the visible portion of the tooth, safeguarding the teeth against further decay or infection and protecting the remaining tooth structure. We make our crowns from a variety of lifelike materials, including ceramic, zirconia, and porcelain-fused-to-metal.

Question: How do I prevent future infections?

Answer: To protect your smile, simply practice good oral hygiene. You should brush your teeth twice a day and floss at least once. In addition, we recommend a thorough dental cleaning about once every six months, this removes plaque and protects your smile from harmful bacteria, reducing your risk of developing an infection.
