"I have a severe toothache and I'm scared it's a root canal."
"I heard root canals are one of the most painful procedures."
"My dentist said the infection reached the nerve."
"I want to know if I need a root canal or if my tooth can be saved another way."
If any of that sounds familiar, take a breath. With modern techniques and thorough numbing, most patients say a root canal feels a lot like getting a filling. We hold same-day openings for patients in real pain, so you're not stuck waiting.
Common signs include lingering sensitivity to hot or cold, a persistent toothache, pain when chewing or biting, and swelling or tenderness in the gums. Sometimes there are no symptoms at all, and it's caught on a routine X-ray.
Modern root canals are performed with local anesthesia, so the procedure itself typically feels similar to getting a filling. The pain people associate with root canals almost always comes from the infection itself, before treatment starts.
Most root canals take about 60 to 90 minutes for a single tooth, though it varies depending on which tooth is involved and how complex the case is. Some cases are completed in one visit; others take two.
For most back teeth, yes. A root canal-treated tooth loses its blood supply and becomes more brittle over time, so a crown protects it from cracking under everyday chewing pressure. Front teeth sometimes only need a filling if enough natural structure remains. We'll tell you honestly what your specific tooth needs.
Here’s what root canal treatment at Bright Smile Dental does for you:
A root canal saves the tooth you already have, instead of pulling it and needing a replacement down the road.
We hold same-day openings for patients in real pain, so you're not stuck waiting for relief.
With thorough numbing and modern technique, most patients are surprised by how manageable the procedure actually is.
Treating an infected tooth promptly protects your surrounding teeth and your overall health.
We'll tell you honestly whether you need a crown afterward, and what that means for cost and timeline.
Severe pain doesn't have to wait. We hold appointment slots specifically for urgent cases.

We take X-rays and confirm exactly what’s going on, so you know whether a root canal is really what your tooth needs.
We numb the area thoroughly so the procedure is as comfortable as possible from start to finish.
We remove the infected tissue, clean and seal the space inside your tooth, and check that the infection is fully addressed.

WHAT OUR PATIENTS SAY
950+ five-star ratings on Google. Here’s what a few patients had to say about their care:
Had 3 impacted wisdom teeth removed and a root canal done during the same procedure and it was virtually painless. Minimal pain even during the following days post-op and was almost completely healed within a week. 100% recommend Dr. Cheung.
Had tooth pain all weekend, decided to give them a call at 8am, came in 9:30am and they took care of me and explained everything very well. They found I needed a root canal and we got it done the same day.
Today I have got a visit to Bright Smile. It was very productive and efficient. Dr. Urell is a real expert and a wonderful human being. Based on X-ray analysis he suggested me the way to fix my problem. Moreover, after explanation of root cause of the issue he set up the appointment and plan in about a one week time frame. Thank you for your care and dedication Bright Smile!
Dr. Cheung and the entire Bright Smile team truly exceeded my expectations when it came to addressing my high levels of dental anxiety. Over the course of the past year, I underwent several major dental procedures, including the removal of my wisdom teeth, a root canal, and routine cleanings. Despite the complexity and potential discomfort of these treatments, Dr. Cheung and the team made the entire process completely painless and stress-free. From the moment I walked in, they were incredibly attentive, patient, and understanding of my fears. They took the time to explain each step of the procedures in a calm and reassuring manner, which helped ease my anxiety significantly. If you’re someone who has been putting off dental work due to fear or anxiety, I can’t recommend Dr. Cheung and the Bright Smile team enough.
This was my first appointment and I was so nervous I almost canceled but I’m very glad I didn’t. Everyone was quite friendly and welcoming and it was definitely one of my most pleasant appointments. I’m so happy Dr. Kim was able to pinpoint the root of my pain that had been going on for quite some time now and finally, after seeing a few other dentists, I now have answers and a game plan! I can’t believe I’m saying this but I’m actually excited to go back. Excellent staff! Excellent service!
I was traveling to Columbus OH for work when I experienced a dental emergency with two teeth that caused severe pain that required 2 root canals and 2 crowns. I called Dr. Cheung and they were incredibly accommodating, squeezing me into their schedule within hours. The entire Bright Smile staff made me feel welcome immediately. Dr. Cheung was professional, gentle and fixed my teeth so I could finish my business trip without pain. Highly recommend Dr. Cheung and the entire Bright Smile Dental team for anyone, locals and travelers!

A root canal removes infected or inflamed tissue from inside your tooth, cleans and seals the space, and saves your natural tooth instead of extracting it.
Most root canals take about 60 to 90 minutes for a single tooth, though it varies depending on which tooth is involved and how complex the case is. Some cases are completed in one visit, others take two.
Modern root canals are performed with local anesthesia, so the procedure itself typically feels similar to getting a filling. The pain people associate with root canals usually comes from the infection itself, before treatment, not the procedure that fixes it.
Common signs include lingering sensitivity to hot or cold, a persistent toothache, pain when chewing or biting, swelling or tenderness in the gums, or a small bump on the gum near the tooth. Sometimes there are no symptoms at all, and it’s caught on a routine X-ray.
Cost depends on which tooth is involved (molars are typically more complex than front teeth) and whether you’ll need a crown afterward. Many insurance plans cover a portion of root canal treatment since it’s restorative care. We’ll give you a clear, itemized estimate at your consultation.
For most back teeth, yes. A root canal-treated tooth loses its blood supply and becomes more brittle over time, so a crown protects it from cracking under everyday chewing pressure. Front teeth sometimes only need a filling if enough natural structure remains. We’ll tell you honestly what your specific tooth needs.
A root canal saves your natural tooth, which is almost always the better long-term option for chewing function and keeping your other teeth from shifting. Extraction is usually reserved for teeth that are too damaged or infected to be saved.
Wait until the numbness fully wears off, then stick to soft foods for a day or two if you have a temporary filling or crown in place. Avoid chewing directly on the treated tooth until your permanent restoration is placed.
With a properly placed crown or filling and good oral hygiene, a root canal-treated tooth can last a lifetime. Most last well over 10 to 15 years.
It’s uncommon, but yes, a root canal can occasionally fail or become reinfected if bacteria find their way back in. Renewed pain or swelling are the main signs, and it’s usually treatable with retreatment.
It can be. Severe pain, swelling, or signs of a spreading infection are treated as emergencies, and we hold same-day openings for exactly that. A root canal that isn’t causing acute symptoms is typically scheduled in the days ahead instead.
We’re here to get you out of pain and help you keep your natural tooth — let’s get started.
