What Patients Say About Our Endodontists
"Dr. Lim was amazing! She has such a calm and professional demeanor — you can tell she focuses on quality over quantity. I felt completely comfortable throughout and she always made sure I was doing ok. I highly recommend her for root canal treatments!"
"I got a root canal completed by Dr. Lim and her assistant — they are amazing! I felt so comfortable I actually fell asleep during the procedure. She always made sure I was doing ok. I highly recommend her!"
"I arrived exhausted, bracing for an hour and a half of torture. Instead, I was given a blanket, a comfortable chair, and Dr. Lim singing softly as she worked. I fell fast asleep. Never before have I left a dental office feeling so refreshed!"
"I came in with a terrible toothache and they got me in the same day. The root canal was completely painless — I couldn't believe it. The team was so kind and reassuring throughout the entire process. Thank you!"
When to Seek Emergency Treatment
If you're experiencing any of these symptoms, you may need an emergency root canal. Submit your details above and our team will prioritise your call first thing tomorrow morning.
Severe Toothache
Intense, throbbing pain that doesn't go away with over-the-counter medication. Pain may worsen when lying down or biting.
Sensitivity to Hot & Cold
Lingering sensitivity to hot or cold foods and drinks that persists long after the stimulus is removed — a key sign of nerve damage.
Swollen or Tender Gums
Swelling, redness, or tenderness around a specific tooth. You may also notice a small bump (abscess) on the gum near the affected tooth.
Darkened or Discolored Tooth
A tooth that has turned grey or dark compared to surrounding teeth, indicating the nerve inside may be dying or dead.
Cracked or Broken Tooth
A visible crack, chip, or fracture in a tooth — especially if accompanied by pain. Bacteria can enter through the crack and infect the pulp.
Pain When Chewing
Sharp pain or discomfort when biting down or chewing food, which may indicate an infection or crack in the tooth's root.

Emergency Evaluation & Treatment
Same visitYour board-certified endodontist performs a thorough exam, manages your pain, and — where possible — treats the issue in a single visit using microscopic precision and 3D imaging.
Pain-Free Treatment, Guaranteed
Modern root canals are nothing like the outdated procedures you may have heard about. With today's technology, they're no more uncomfortable than getting a filling.
Sedation Options
We offer multiple sedation options — from nitrous oxide to oral sedation — so you can relax completely during your procedure. Your comfort is our priority.
3D CBCT Imaging
Our high-resolution cone beam CT scanner creates detailed 3D images of your tooth anatomy, allowing precise diagnosis and treatment planning — no guesswork involved.
Surgical Microscopes
Our endodontists use advanced surgical microscopes with up to 25x magnification, revealing the intricate canal system of your tooth for the most thorough treatment possible.
The Truth: Root Canals Don't Hurt — Toothaches Do
The biggest misconception about root canals is that they're painful. In reality, the procedure itself is designed to relieve pain, not cause it. It's the infected tooth that causes the agony — a root canal is the cure.
With modern anesthesia, sedation options, and microscopic precision, most patients report the procedure feels no different than getting a routine filling. Many even fall asleep during treatment.
Don't Suffer Through the Night Alone

Over-the-counter pain relievers such as ibuprofen (Advil) or acetaminophen (Tylenol) can help reduce inflammation and manage discomfort. Avoid very hot or cold foods and drinks, and try to sleep with your head slightly elevated. If you experience severe swelling, difficulty breathing or swallowing, please go to your nearest emergency room.
Common signs include severe toothache, prolonged sensitivity to hot or cold, swollen or tender gums, a darkened tooth, or pain when chewing. If you're experiencing any of these symptoms, submit your details now — the sooner we treat the infection, the better the outcome.
No. The procedure is designed to relieve your pain, not cause it. Your mouth will be completely numbed, and we offer sedation options for anxious patients. Most patients say the relief from their toothache far outweighs any minor discomfort during the procedure.

The cost varies depending on which tooth is affected and the complexity of the case. We'll provide a full cost estimate before beginning any treatment. We accept most major dental insurance plans and offer financing options. Our team will discuss all of this with you when we call.
