Let’s talk about one of the most misunderstood words in dentistry: the root canal. If you’re like most people, just hearing it might make you a little nervous. For years, root canals have been the punchline of jokes about pain and discomfort. But what if we told you that this reputation is completely outdated and that a root canal is actually a pain-relieving procedure?
The truth is, modern root canal treatment is a comfortable, routine procedure that saves your natural tooth and stops the pain caused by an infection. Dr. Ed Lazer of Cosmetic and Advanced Dentistry in Baltimore is here to walk you through every step, calm your fears, and show you exactly what to expect.

Root Canals Demystified: Your Guide to a Pain-Free Smile
What Exactly Is a Root Canal?
Let’s clear up the confusion first. “Root canal” actually refers to the natural, hollow space inside your tooth. Think of it like the trunk of a tree, with roots extending down into your jaw. This space contains the tooth’s “pulp”. Pulp is a soft tissue made up of nerves, blood vessels, and connective tissue that helps the tooth grow.
When we talk about “getting a root canal,” we mean a procedure to treat this area. This becomes necessary when the pulp inside gets infected or severely inflamed. This infection can be caused by a deep cavity, a crack in the tooth, or an injury. If the infected pulp isn’t removed, it can cause a painful abscess and can even lead to you losing the tooth entirely.
A root canal procedure isn’t the cause of pain, it’s the solution.
How Do I Know if I Need a Root Canal?
Your body is pretty good at sending signals when something’s wrong. Needing a root canal often comes with some clear signs. Sometimes the infection can be “silent” and only spotted by your dentist during a check-up with an X-ray.
Here are the most common symptoms to watch for:
- Serious Toothache: The most common sign is a persistent toothache. The pain might be a constant, dull throb, or it might flare up sharply when you bite down or put pressure on the tooth.
- Temperature Sensitivity: Do you feel a sharp, lingering pain when you drink hot coffee or eat ice cream? This sensitivity that lasts long after the food or drink is gone is a classic indicator of pulp damage.
- Swollen and Tender Gums: The gums around the painful tooth might become red, swollen, and tender to the touch. Sometimes, a pimple-like bump can even appear on the gums near the tooth. This is called an abscess and is a sign of infection.
- Tooth Discoloration: An infected tooth may start to look darker compared to the teeth around it. This happens because the nerve inside has died.
- A Chipped or Cracked Tooth: If you’ve recently chipped or cracked a tooth, bacteria can sneak in and infect the pulp. A root canal is necessary to save it.
If you’re experiencing any of these symptoms, the best thing you can do is call your dentist. The sooner we can treat it, the less discomfort you’ll feel.
Your Step-by-Step Guide to the Root Canal Procedure
Knowing what’s going to happen can take away a lot of the fear. Here’s a simple breakdown of the entire process:
Step 1: Getting Comfortable
Your comfort is our top priority. We will use a local anesthetic to completely numb the tooth and the surrounding gum. You’ll be awake, but you won’t feel any pain during the procedure. If you feel dental anxiety, we also offer sedation dentistry options to help you feel completely relaxed and at ease.
Step 2: The Cleaning Process
Once you’re numb, your dentist will place a small protective sheet called a “dental dam” over the area to keep the tooth clean and dry. Then, a very tiny opening is made in the top of the tooth to access the pulp chamber. Using miniature, precise instruments, your dentist will gently remove the infected or damaged pulp, clean the entire inside of the tooth, and then disinfect the empty root canals to make sure all the bacteria are gone.
Step 3: Filling and Sealing
After the inside of the tooth is cleaned and shaped, it’s filled with a biocompatible, rubber-like material called gutta-percha. This seals the canals to prevent new infection. The small opening in the top of the tooth is then closed with a temporary filling.
Step 4: The Final Restoration
Because a tooth that has had a root canal is more fragile, it needs a permanent custom crown to protect it and restore its full strength for chewing. This crown is custom-made to match the color and shape of your natural teeth. You’ll come back for a separate, short appointment to have this crown placed, and then you’re all done!
The Big Myth: “Are Root Canals Painful?”
This is the question we hear most often. The painful part is the infection itself. The infected pulp is swollen and inflamed inside the hard walls of your tooth, which causes a lot of pressure and pain.
The root canal procedure stops this pain. By removing the source of the infection, we relieve the pressure and the pain. Most patients say that the procedure itself feels very similar to getting a standard filling. In fact, many patients leave our office feeling immediate relief from the pain they’ve been suffering from.
