Few things stop you in your tracks faster than tooth pain. But while some issues clear up with a good cleaning or quick filling, others go deeper. When a tooth infection reaches the inner pulp, a root canal may be your best option for saving that tooth and ending the discomfort for good.

If you’ve been dealing with nagging dental symptoms or intense pain that just won’t quit, this guide will help you figure out what might be going on and what your next step should be.

What Is a Root Canal?

A root canal treatment is a dental procedure that removes infected or damaged pulp tissue inside the tooth. That pulp houses nerves and blood vessels, and when it becomes inflamed or infected, it causes serious pain and can even spread infection if untreated.

At Solomon Dentistry in Summerville, SC, root canal therapy is offered by endodontic specialists who focus on keeping your natural teeth intact while eliminating pain and infection.

Common Signs You Might Need a Root Canal

Some signs are hard to miss. Others are more subtle, and they can creep up on you. Knowing what to look for can make all the difference between a simple root canal and a bigger dental issue down the road.

1. Persistent Tooth Pain

Pain is the red flag most people can’t ignore—and with good reason. If you have a toothache that lingers for more than a couple of days, especially one that throbs or radiates to your jaw or ear, it’s time to call the dentist.

Pain like this can be triggered by chewing, biting, or even without any pressure at all. It’s one of the biggest root canal symptoms that people notice first.

2. Sensitivity That Won’t Go Away

Tooth sensitivity isn’t always cause for concern. But if you feel sharp or lingering discomfort when drinking hot coffee or eating ice cream, there might be more going on beneath the surface.

Tooth sensitivity and root canal needs are often connected when the sensitivity doesn’t fade even after the temperature returns to normal. That usually signals nerve involvement, something a regular filling won’t fix.

3. Swollen or Tender Gums

Your gums are like an early warning system for dental trouble. Swelling, tenderness, or puffiness in one area could mean an infection under the surface.

Sometimes, you may even see a small pimple-like bump on the gum or a dental abscess. That’s your body’s way of draining infection, but also means you need treatment fast.

4. Tooth Discoloration

A tooth that darkens or turns gray may not just be stained—it could mean the internal tissue is damaged or dying. This often happens after trauma or untreated decay that reaches the pulp. If you notice color changes that don’t improve with whitening, it might be time to explore root canal symptoms with your dentist.

5. A Tooth That Feels “Different”

Not every symptom is dramatic. Some people describe a feeling of pressure or a tooth that feels “off” when biting down. Others mention a sense of numbness or dull aching. These vague sensations often go ignored, but they can be a growing tooth infection warning signs.

What Happens During a Root Canal?

If you’ve never had one, the idea of a root canal can sound intimidating. Thankfully, modern dental techniques make it a much smoother experience than its outdated reputation suggests.

Here’s a quick overview on the process of root canal treatment in Summerville, SC:

Step 1: Local Anesthetic—You’ll be numbed completely in the area being treated. There will be no pain, just pressure.

Step 2: Pulp Removal – The dentist creates a small opening in the top of your tooth to remove the infected pulp.

Step 3: Cleaning and Disinfection – The canal chambers are cleaned thoroughly and disinfected to remove all bacteria.

Step 4: Filling the Canals – Once the area is clean, the dentist fills the canals with a biocompatible material to seal them off and prevent reinfection.

Step 5: Crown Placement—A custom crown is placed on top of the tooth to strengthen it and restore its natural function and look. Depending on the tooth’s condition, this typically takes 1–2 appointments.

What to Expect After the Procedure


Healing after a root canal is usually quicker and easier than people expect. However, if the area was severely infected beforehand, you might feel mild soreness for a day or two. Over-the-counter medication often helps ease any post-treatment symptoms.

Root canal recovery time varies, but most patients return to normal activities the same or the next day. As the tooth adjusts, sensitivity decreases, and chewing becomes more comfortable. Your dentist may recommend avoiding hard or sticky foods until the permanent crown is placed.

The Long-Term Benefits of Root Canal Therapy

Why go through the trouble of saving a tooth with a root canal? Because the benefits add up, especially when the procedure is done early.

Here’s what you gain by choosing this treatment:

  • Pain relief: Say goodbye to throbbing, stabbing, or lingering toothaches
  • Tooth preservation: Keeps your natural tooth in place instead of removing it
  • Prevent infection: Stops bacteria from spreading to other areas
  • Normal bite function: Chewing and speaking feel natural again
  • Oral health support: Keeps adjacent teeth aligned and healthy
  • Cost-effective care: Avoids more expensive restorations or extractions
  • Aesthetics: The final crown restores the appearance of your tooth

For many patients, root canal therapy also means peace of mind. Once the infection is gone, you regain control of your dental health.

When to See a Dentist

If any symptoms we’ve covered sound familiar, it’s time to get checked out. A quick evaluation can determine if your tooth needs a root canal or if there’s another fix. Either way, the sooner you act, the better your outcome.

The infection may remain beneath the surface even if the pain has disappeared temporarily. Ignoring it won’t help and could create a much bigger problem later.
