Root Canals Q & A
What is a root canal?
Dr. Zhu performs a root canal when the pulp deep inside your tooth enamel is infected. This pulp consists of blood vessels and nerves that are important to your tooth’s development but are no longer essential once your tooth is fully matured.
During a root canal, Dr. Zhu removes the infected pulp and replaces it with a biocompatible material. He leaves the main structure and root of your tooth intact.
How do I know if I need a root canal?
Routine X-rays may reveal an infection in your tooth’s pulp. Often, you’ll have symptoms, too, that include:

- Pain in the affected tooth
- Abscess or pus drainage
- Prolonged sensitivity to hot and cold
- Tooth discoloration
- Soreness when you’re chewing or pressing on the tooth.
If you’re experiencing any of these symptoms, don’t wait to contact Freedom Dental. Delaying treatment can allow the infection to spread, which can cause you to lose the tooth entirely.
Symptoms can also show up in a tooth that’s had a prior root canal. Usually, this is an indication that the root canal has failed and requires retreatment.
What happens during a root canal?
Dr. Zhu numbs the treatment area, so you won’t feel any pain, just pressure, during your root canal.
He then makes a small hole in your tooth to access the pulp. He scrapes away all of the infected material and rinses the area with a special solution to make sure no bacteria lingers.
Dr. Zhu places gutta-percha, a rubbery material, into the space where your pulp was. The site is carefully sealed to complete the procedure.
You need a porcelain crown to top off the tooth and protect it from any further damage. Freedom Dental processes these crowns in-house using the CEREC system, so you don’t have to schedule a separate visit for crown placement.
Frequently Asked Questions About Root Canal
How much does a root canal cost in Fairfield, CA?
The cost of a root canal can vary depending on which tooth is treated and the complexity of the infection. Molars generally cost more than front teeth because they have multiple roots. At Freedom Dental, Dr. Cheng Zhu provides upfront pricing, and our team will review your treatment plan with you before any work begins. Flexible financing options are also available for patients who wish to spread out payments.
Does dental insurance cover root canal treatment?
Most dental insurance plans provide at least partial coverage for root canal therapy since it is considered a medically necessary procedure to save a tooth. The extent of coverage depends on your plan’s benefits and deductibles. Our staff will gladly contact your provider and give you a clear breakdown of your out-of-pocket costs so there are no surprises.
How long does it take to recover after a root canal?
Recovery from a root canal is usually quick. Many patients return to normal activities the same day or the following day. Mild discomfort or tenderness is typical for a few days, but this can be handled with non-prescription pain medications. Consuming softer foods and refraining from biting down on the treated tooth until the permanent crown is installed aids in promoting effective healing.
Can I avoid having a root canal if my tooth hurts?
Unfortunately, tooth pain caused by deep infection won’t go away on its own. Antibiotics or pain relievers may temporarily ease discomfort, but cannot remove infected pulp. The infection can spread without proper treatment and cause tooth loss or even systemic health concerns. A root canal performed by Dr. Zhu is the safest and most effective way to preserve your natural tooth.
How long does a root canal procedure take?
Most root canal treatments can be completed in about 60 to 90 minutes, depending on the severity of the infection and the number of canals inside the tooth. Because Freedom Dental offers same-day crowns with the CEREC system, patients often complete the entire process, including crown placement, in just one visit.

What happens if I delay getting a root canal?
Delaying treatment allows the infection to worsen. This can result in an abscess, bone loss around the tooth, or the need for extraction. In some cases, untreated infection may even impact overall health. Seeking care promptly gives you the best chance to save your natural tooth and avoid more complex and costly dental procedures.
Will I need time off work after my root canal?
Most patients feel well enough to return to work or school the next day, and some even resume their normal activities the same day. If your job requires strenuous physical activity, Dr. Zhu may recommend resting for 24 hours before returning to avoid unnecessary stress during recovery.
How long will my tooth last after a root canal?
A tooth properly treated with a root canal and restored with a crown can last for decades or even a lifetime with good oral hygiene. Consistent dental check-ups, along with regular brushing, flossing, and steering clear of behaviors such as chewing on ice or using teeth as tools, all contribute to extending the longevity of your restored tooth.

Is a root canal painful?
A root canal isn’t painful, but the symptoms that cause you to need one are. You may feel sore and sensitive for a few days following the root canal, but these side effects subside, and you get long-term relief from long-term pain.
If pain continues for a week or more after your procedure, contact the office to make sure you don’t have a complication from the procedure.

Root canal therapy is a very common procedure. It has a reputation of being undesirable and painful. But when done properly it is actually painless. Every tooth in your mouth is composed of a crown and a root. When a cavity or bacteria penetrates the tooth, the root and its nerves become irritated. As a result, the bacteria within the pulp cavity needs to be removed and cleaned in order to restore the tooth to its healthy state. Following the procedure, the tooth is fragile and consequently is restored with the natural crown for a lifetime of durability. Root canals have a success rate of 95% or greater. Most root canal are diagnosed by patients’ sensitivities to a specific tooth. Be sure to consult your dentist any symptoms or discomfort occur.
