Understanding Your Treatment
What Is Root Canal Treatment?
A root canal is a treatment that removes infected or damaged tissue from inside a tooth to relieve pain and save it from extraction. Using digital imaging and CBCT scans, we map the tooth's internal structure for precise, efficient care. The infected pulp is cleaned out, the canal is sealed, and the tooth is usually protected with a crown. Modern techniques make today's root canals far more comfortable than their reputation suggests.
The Benefits
The Benefits of Root Canal Treatment

Is It Right for You?
Signs You May Need Root Canal Treatment
Severe Pain
You have a persistent toothache or lingering sensitivity to hot and cold temperatures.
Gum Swelling
You notice swelling, tenderness, or a small bump on the gum near a tooth.
Deep Decay
A large cavity has reached the nerve inside the tooth.
Tooth Injury

Aftercare
How to Care for Your Tooth After a Root Canal
Recovering from a root canal is usually simple, and a little aftercare goes a long way toward protecting your results. For the first few days, you may feel mild soreness that's easily managed with over-the-counter pain relievers, and it's wise to avoid chewing on the treated side until your permanent crown is placed. Keep up with gentle brushing and flossing, and stick to softer foods at first. Attending your follow-up visits at Elite Dentistry ensures your tooth stays healthy and fully restored.

Do I need a crown after a root canal?
In many cases, yes. A crown adds strength and protection, especially for molars and heavily damaged teeth, and we can often place one the same day.
What are the alternatives to a root canal?
The main alternative is removing the tooth entirely. Saving your natural tooth is almost always the better long-term option.
Is root canal treatment painful?
With modern techniques and local anesthetic, the procedure is generally not painful. Any mild soreness afterward usually eases with over-the-counter pain relief.
How soon can I get back to normal after a root canal?
Most patients return to their regular activities the very next day. We will share simple aftercare tips to keep you comfortable.
Is root canal treatment covered by insurance?
Most dental plans cover part or all of a root canal. Our team will help you check your benefits and make the most of your coverage.
How Much Do Root Canals in Rancho Santa Margarita, CA, Cost?
The cost of a root canal depends on which tooth is affected and the complexity of the infection, with front teeth generally costing less than molars. While the cost may be a concern, saving your natural tooth is almost always more affordable than extracting it and later replacing it with an implant or bridge. At Elite Dentistry, we work with most insurance providers, and many plans cover a significant portion of root canal treatment. We also offer flexible financing and new patient specials to keep care accessible.
What Happens If You Delay a Root Canal?
Putting off a needed root canal can turn a manageable problem into a serious one. An infected tooth won't heal on its own, and the bacteria inside it will continue to spread, often leading to a painful abscess, swelling, and damage to the surrounding bone. In severe cases, the infection can travel elsewhere in the body and threaten your overall health. Acting quickly gives Dr. Lari the best chance to save your natural tooth and spare you from more extensive, costly treatment down the road.
