Of all the dental problems a person can face, “root canal” is often the phrase that causes the most anxiety. Over the years, root canal treatment has earned a reputation for being invasive and unpleasant, so much so that many people put off care they actually need. At Boston Smile Center, our team wants to be clear about this: with modern anesthesia and technique, root canal therapy is a comfortable, routine way to relieve pain and save a tooth that would otherwise need to be removed.
How Do I Know If I Need a Root Canal?
A root canal becomes necessary when the soft tissue inside a tooth, called the pulp, becomes infected or inflamed, usually from deep decay, a crack, or repeated dental procedures on the same tooth. Common signs that could indicate the need for treatment include:
- Severe pain when chewing or applying pressure to one or more teeth
- Gums near the tooth that look tender, red, or swollen
- Sharp sensitivity to hot or cold that lingers well after the stimulus is removed
- A tooth that has suddenly darkened compared to the teeth around it
According to the American Dental Association, some infected teeth show no symptoms at all, and the problem is only caught on a routine x-ray. That is one reason regular checkups matter even when nothing feels wrong.
What Happens During Root Canal Therapy?
Your dentist begins by numbing the area thoroughly, so the tooth is fully asleep before any work starts. A small opening is made in the top of the tooth to access the infected pulp, which is carefully removed along with any bacteria inside the root canals. Once the space is clean, it is filled with a biologically inert material and sealed to protect it from future infection. In most cases, a custom-made crown is placed afterward to restore the tooth’s full strength and shape, since a tooth that has had a root canal can become more brittle over time.
Most root canal procedures are completed in one to two visits. Because the tooth is numb throughout, patients typically feel little to nothing during the appointment itself, and any lingering soreness afterward is usually mild and manageable with over-the-counter pain relief for a few days.
Why Save the Tooth Instead of Removing It?
A root canal preserves your natural tooth, which keeps your bite aligned and avoids the extra steps and cost of replacing a missing tooth with a dental implant or bridge later on. Whenever a tooth can realistically be saved, our team treats that as the first option, and extraction becomes a last resort rather than a starting point.
What Happens After Treatment?
Once the crown is placed and the site has settled, a treated tooth functions like any other tooth in your mouth. Continue brushing twice a day, flossing once a day, and keeping your regular cleanings so your dentist can monitor the tooth over time. If you ever notice new pain, swelling, or sensitivity in a tooth that has had a root canal, let your dentist know, since it can sometimes signal that reinfection has occurred and needs attention.
If you are noticing any of the warning signs above, do not wait for the pain to get worse. Contact Boston Smile Center to schedule a consultation. Our team works hard to make sure every patient feels comfortable and cared for during treatment, root canals included.
Frequently Asked Questions About Root Canal Therapy
Does a root canal hurt more than a filling?
No. Because the tooth is fully numbed before treatment begins, a root canal feels similar to getting a filling. Most of the discomfort people associate with root canals actually comes from the infection itself before treatment, not the procedure.
How long does a root canal take to complete?
Most root canals are completed in one to two appointments, depending on which tooth is affected and how complex the root structure is. Your dentist will let you know what to expect at your evaluation.
Will I need a crown after a root canal?
In most cases, yes. A tooth that has had a root canal loses some structural strength over time, so a custom crown is typically placed afterward to protect it and restore normal chewing function.
What happens if an infected tooth is left untreated?
Left untreated, an infected tooth can develop an abscess, spread infection to the surrounding bone, and eventually require extraction. Treating the infection early with a root canal is almost always the more conservative option.
How soon can I eat normally after a root canal?
Wait until the numbness fully wears off before eating to avoid accidentally biting your cheek or tongue. Stick to softer foods on the treated side for a day or two, then return to your normal diet as comfort allows.
