Easier than you think

Most patients say the hardest part was worrying about it. We numb you fully, work gently, and get you back to your day.
It's not what you've heard
Most patients walk out of a root canal saying, "That was way easier than I thought." We numb the area completely, work efficiently, and check in with you the whole way through. You're in good hands.
What is a root canal?
Inside every tooth is a soft tissue called pulp, which contains nerves and blood vessels. When that tissue gets infected (usually because of a deep cavity, a crack, or trauma to the tooth) it causes pain and can lead to a bigger problem if it's not treated.
A root canal is the procedure that removes the infected tissue, cleans the inside of the tooth, and seals it up. The tooth stays in place. You get to keep your natural tooth instead of pulling it.
Signs you might need a root canal
Common signs include:
- Sharp pain when chewing or biting down
- Lingering sensitivity to hot or cold, even after the temperature is gone
- A tooth that's darkening or changing color
- Swelling or tenderness in the gum near a specific tooth
- A small bump on the gum that looks like a pimple
- A deep cavity or a tooth with a known crack
Not every painful tooth needs a root canal. Some can be saved with a simple filling, and a few are too far gone and need to be extracted. We'll take an X-ray, look at the tooth carefully, and tell you honestly what your options are.
What to expect
- Exam and X-ray. We look at the tooth, take an X-ray, and confirm a root canal is the right call.
- Numbing. We numb the area completely before we start. You won't feel sharp pain during the procedure, just light pressure.
- Cleaning the tooth. We make a small opening in the top of the tooth, remove the infected tissue, and clean the inside thoroughly.
- Sealing. We fill the cleaned space with a soft material that keeps bacteria out.
- Restoration. Most teeth that have a root canal also need a crown to protect them long-term. We'll plan and schedule that with you.
- Follow up. We check the tooth at your next visit to make sure everything is healing well.
Cost and insurance
Root canal pricing depends on which tooth is affected (front teeth are usually less than molars) and whether you need a follow-up crown. We'll quote you a clear total before we start.
- Most dental insurance plans cover root canals.
- Smile Plan members save on root canal treatment.
- Third-party financing through CareCredit, Alphaeon, and Cherry spreads the cost into monthly payments.
- HSA and FSA accepted.
