What is a Root Canal?
A tooth has two basic parts, the crown and the roots. The crown is mainly above the gum, and the roots, which attach your tooth to your jawbone, are below. Inside the tooth is a hollow area, called the root canal.
The root canal contains a substance called pulp, which is a network of nerves and blood vessels that nourish the tooth that senses extreme temperatures and pressure on the tooth.
If the pulp becomes injured or diseased, it dies. This can happen because of a deep cavity, damage to the tooth, or infection from a wisdom tooth. Bacteria penetrate through a crack or cavity and cause infection. Eventually, the tooth becomes loose, the tissue around it swells, and abscesses may form beneath the tooth.
Relieve Pain and Save Your Natural Tooth
If you’re experiencing persistent tooth pain, sensitivity to hot or cold, or swelling around the gums, you may need a root canal. At Metro City Dentistry, we offer advanced, gentle root canal therapy to remove infection, relieve discomfort, and preserve your natural tooth, helping you avoid extraction and maintain a healthy, functional smile.
Signs You May Need a Root Canal
- Ongoing toothache or pressure
- Pain when chewing or touching the tooth
- Extreme sensitivity to hot or cold
- Swollen or tender gums
- Darkening or discoloration of the tooth
- A small bump or pimple on the gum near the affected tooth
If you’re experiencing any of these symptoms, don’t wait — getting timely treatment can save your tooth and stop the infection from spreading.
What to Expect During Treatment
Root canal therapy is usually completed in one to two appointments. After numbing the area, your dentist will create a small opening in the tooth to access the pulp chamber. The infected tissue is removed, the canals are cleaned and shaped, and the space is filled with a biocompatible material. In most cases, a dental crown is placed on the tooth afterward to protect it and restore full strength and function.
At Metro City Dentistry, we prioritize your comfort. For patients who feel anxious about dental work, we offer sedation dentistry options to ensure a stress-free experience.
Aftercare and Recovery
Recovery from a root canal is typically fast and easy. Some mild soreness or sensitivity is normal for a day or two, which can be managed with over-the-counter pain relievers. Maintaining good oral hygiene, attending regular dental checkups, and protecting your restored tooth will help ensure long-term success.
