Root Canal Therapy
The words "root canal" carry an outdated reputation. Today's procedure is gentle, efficient, and — for most patients — surprisingly comfortable.

Debunking the myths
Root canal therapy has a reputation problem. Decades ago the procedure could be uncomfortable, but modern techniques, advanced anesthetics, and precision instruments have changed everything. Most patients at Bridgewater Dental Center tell us the experience felt no different from having a filling placed. The real discomfort comes from the infection itself — not the treatment that resolves it. Dr. Sang Kim takes extra time to ensure you are fully numb and completely at ease before any work begins. For patients across Bridgewater, Harrisonburg, and the Shenandoah Valley, we want the reality of root canal therapy to replace the old stories.
How the procedure works
When bacteria reach the pulp — the soft tissue inside your tooth containing nerves and blood vessels — the result is infection and often intense pain. During root canal therapy, Dr. Kim creates a small opening in the crown of the tooth, carefully removes the infected pulp, and cleans and disinfects each canal. The canals are then shaped and filled with a biocompatible material to seal out future bacteria. In most cases a dental crown is placed over the treated tooth to restore its strength and protect it from fracture. The entire procedure is typically completed in one or two visits.
Modern comfort and sedation
We understand that dental anxiety is real, and no amount of reassurance replaces the experience of actually feeling comfortable in the chair. That is why our Bridgewater office offers sedation options for patients who need them. Whether you prefer mild oral sedation to take the edge off or a deeper level of relaxation, Dr. Kim will discuss your options before treatment day so there are no surprises. You should leave thinking, "That was so much easier than I expected."
Saving your natural tooth
A root canal is almost always preferable to an extraction. Your natural tooth maintains the bone structure in your jaw, keeps neighboring teeth from shifting, and avoids the need for an implant or bridge down the road. With proper care — regular brushing, flossing, and checkups — a root-canal-treated tooth can last a lifetime.

Frequently Asked Questions
Does a root canal really hurt?+
Modern root canal therapy is far more comfortable than its reputation suggests. Dr. Kim uses advanced anesthetics to make sure you're fully numb before starting, and most patients at our Bridgewater office say it feels no worse than getting a filling.
How do I know if I need a root canal?+
Common signs include a persistent toothache, prolonged sensitivity to hot or cold, swelling or tenderness near the tooth, and darkening of the tooth. If you're experiencing any of these symptoms, schedule an evaluation so Dr. Kim can take a closer look.
How long does a root canal take?+
Most root canal procedures are completed in one or two visits, with each appointment lasting about sixty to ninety minutes. The exact time depends on which tooth is being treated and how complex the canal system is.
Will I need a crown after a root canal?+
In most cases, yes. A crown protects the treated tooth from fracture and restores its full strength. Dr. Kim will place a temporary restoration right away and schedule a follow-up to fit your permanent crown.
What happens if I skip a root canal?+
An untreated infection will not go away on its own. It can spread to surrounding bone and tissue, cause an abscess, and eventually lead to tooth loss. A root canal saves the tooth and stops the infection before it gets worse.
Is it better to pull the tooth instead?+
Saving your natural tooth is almost always the preferred option. Your own tooth maintains bone structure, keeps neighboring teeth from shifting, and avoids the cost and complexity of replacing it with an implant or bridge down the road.
