Root Canal Therapy

If you get an infection in the soft inner section of a tooth, also called the pulp, the entire tooth can begin to rot and die. A root canal procedure will remove the pulp to keep the infection from spreading and to relieve your pain. Once the pulp is removed, Dr. Wally Cantu and his staff will seal the canals of the root, and add a filling to the inside of the tooth or put a crown over it to guard against infections in the future.

Since infections can also enter the blood and infect other parts of the body, root canals are important in maintaining your overall health. If you have heart problems, you should be sure to take antibiotics before and after your root canal to protect against infections.

If you have a toothache or infection, make an appointment to look at your tooth and talk about treatments, including a root canal. A root canal can prevent more serious dental problems and relieve your pain.

Before the root canal begins, the dentist will numb the patient’s teeth and gums with a local anesthetic, as well as nitrous oxide gas for further patient comfort and relaxation if needed.

Once the patient is prepared, we will carefully remove the pulp from the decayed tooth, both the visible portion of the tooth and the root below the gum line.

After the tooth is removed, Dr. Cantu will place a crown or filling material to strengthen and protect the treated tooth.

After the root canal treatment, the patient’s lips and gums will remain numb for a few hours, but the patients will be able to drive and leave to recover at home. If the patient is feeling any pain after the procedure, they can take an over-the-counter painkiller, following the instructions on the label.

If we placed a temporary crown over the tooth, the patient will return after the permanent crown is created and sent back to the office. Dr. Cantu will then place the crown and check the fit.

The patient should return for annual dental exams and professional cleanings twice a year, or as recommended by our team.

The cost of the root canal will depend on how many teeth are being treated and where the teeth are located in the mouth.

The front teeth cost from $300 - $1,500, bicuspids cost from $400 - $1,800, and molars cost $500 - $2,000.

Additional costs may be added for emergency cases if the patient needs the same day or weekend root canal.

If a crown or other dental implant is used, that cost will be added to the patient’s total cost.

When I arrived at my appointment, I was so afraid I wanted to leave. But then I told Dr. Cantu exactly what was wrong and how I felt. Well, he went step by step with everything and when I felt any pain he would stop and numb my cheek. Well after the procedure was done, pulled a tooth and did a root canal, I didn't feel any pain, the whole day, or the next day, just a bit sore. So thank you Dr. Cantu for taking my fear away. I would recommend anyone to go to Crown Dental they do an awesome job


Just started going to crown dental and it's been a great experience each time I go. The staff is helpful and knowledgeable and Dr. Cantu does great work. Had to get a root canal and almost fell asleep a few times just because i couldn't feel a thing, no pain at all. Best dental experiences I've ever had.
