Patients describe the office as warm and home-like — the opposite of the cold, clinical setting that fuels dental fear. Whether this is your first root canal or you have been putting one off for years, Dr. Rhie will meet you where you are.

Signs You May Need a Root Canal

Your tooth may be telling you something. These are common signs that the inner part of a tooth — the pulp — may be infected or damaged:

• A persistent, throbbing toothache that does not go away
• Sharp pain when biting or chewing
• Sensitivity to heat or cold that lingers after the source is removed
• Swelling or tenderness in the gums near a tooth
• A small pimple-like bump on the gums
• A tooth that has darkened or changed color

Not every symptom means a root canal is needed, but these signs are worth a prompt evaluation. If you are experiencing any of them, our dental emergencies and same-day appointments page explains how quickly we can get you seen.

What to Expect During Your Root Canal Appointment

Root canal therapy is more straightforward than most patients expect. Dr. Rhie begins by numbing the area completely so you do not feel discomfort during the procedure. Once you are comfortable, she gently removes the infected tissue from inside the tooth, cleans and shapes the inner canals, and seals the tooth to prevent future infection. Most appointments take between 60 and 90 minutes.

After your root canal, the treated tooth is typically restored with a crown or bridge to protect it and restore full function. Dr. Rhie will walk you through exactly what to expect at each step — nothing happens without your understanding and agreement.

Do You Need a Root Canal or an Endodontist?

An endodontist is a specialist who focuses exclusively on the inner structures of teeth. If you have been searching for an endodontist in Arlington Heights, IL, it is worth knowing that most root canal cases do not require a specialist referral. Dr. Rhie performs root canal therapy in-office for the majority of patients, which means less hassle, no extra appointments, and care from a doctor you already trust. In rare situations involving unusually complex anatomy or advanced infection, she will refer you to a trusted specialist — and she will explain clearly why that is the better path for your specific case.

What Happens If You Skip Treatment?

A tooth infection does not resolve on its own. Without treatment, the infection can spread to surrounding teeth, the jawbone, and in serious cases, beyond the mouth. The tooth itself may eventually need to be extracted — which then opens the door to a longer, more involved process of replacing it. Saving your natural tooth through root canal therapy is almost always the simpler, more cost-effective outcome. If extraction does become unavoidable, [dental implants](/services/restorative-dentistry/dental-implants) are the closest long-term replacement option.

Root Canal Therapy vs. Tooth Extraction: Which Is Right for You?

When a tooth is infected, the goal is always to save it if possible. A root canal removes the infection while keeping your natural tooth in place — preserving your bite, your bone structure, and the feel of a tooth that belongs there. Extraction removes the problem but also removes the tooth, which can affect neighboring teeth over time and may require a replacement like a dental implant or bridge.

For most patients, root canal therapy is the preferred path. It is typically covered by insurance, completed in one or two visits, and allows you to keep what you already have. Tooth extraction may be recommended when a tooth is too damaged to restore — and in that case, Dr. Rhie will explain your replacement options clearly.
