When you think of dental care, Root Canal Treatment might not be the first thing that comes to mind—but understanding when you might need one can help save your tooth and relieve pain before it worsens. At Sandquist DDS in Las Vegas, NV, our goal is to help you recognize the signs early and get the gentle, effective care you need.
If you’ve been wondering whether your tooth pain or sensitivity could point to something more serious, this guide explains the six most common signs you may need a root canal, what the procedure involves, and when it’s time to schedule an exam.
What Is a Root Canal?
A root canal (also called root canal therapy or endodontic treatment) is a procedure that removes infected or inflamed tissue from inside your tooth, called the pulp. This pulp contains nerves and blood vessels that can become damaged from deep decay, cracks, or trauma.
During a Root Canal Treatment in Las Vegas, Dr. Sandquist carefully removes the infected pulp, cleans and disinfects the inner chamber, and then seals it to prevent future infection. Finally, a custom dental crown is placed to strengthen and restore the tooth’s natural function and esthetics.
Despite its reputation, modern root canal treatment is usually no more uncomfortable than getting a regular filling. With advanced techniques and gentle anesthetic options, most patients experience quick relief and can return to normal activities the same day.
1. Persistent Toothache
One of the first and most noticeable signs that you might need a root canal is a persistent toothache. This pain can range from dull and throbbing to sharp and severe, and it often doesn’t go away even after taking over-the-counter pain medication.
A constant ache may indicate that the pulp inside your tooth is inflamed or infected. In some cases, the pain might worsen when you lie down or when pressure is applied to the tooth.
Because toothaches can have many causes—including cavities, gum disease, or sinus issues—only a dentist can determine whether the source is within the root canal system. If your tooth pain has lasted more than a few days, it’s important to schedule an exam at Sandquist DDS to determine the cause and protect your oral health.
2. Lingering Sensitivity to Hot or Cold
A little sensitivity when eating ice cream or sipping coffee isn’t unusual. But if that sensitivity lingers long after you’ve finished, it may be a sign that the tooth’s nerve is compromised.
Lingering sensitivity—especially one that causes a deep, dull ache or lasts for several minutes—is often linked to nerve damage or infection within the pulp chamber. When the pulp becomes inflamed, temperature changes trigger pain because the nerve endings are overly reactive.
Root canal therapy can remove this damaged tissue, eliminate the infection, and stop the painful sensations while allowing you to keep your natural tooth.
3. A Chipped or Cracked Tooth
A chipped or cracked tooth may seem minor, but it can create an entry point for bacteria to reach the inner pulp. Even a hairline fracture caused by chewing something hard or an injury can lead to infection if left untreated.
Once bacteria enter the root canal, they multiply and cause inflammation and pressure inside the tooth. You might notice pain when chewing or a sharp sensitivity when biting down.
If your tooth has visible cracks or feels painful after a recent chip, it’s best to see a dentist as soon as possible. In many cases, early root canal treatment can save the tooth before infection spreads to the surrounding bone or gum tissue.
4. A Darkened or Discolored Tooth
Sometimes, the signs of infection aren’t painful at all. A tooth that gradually darkens or turns gray can signal nerve damage inside the tooth.
A darkened or discolored tooth often means the pulp has died or is severely inflamed. This can occur after trauma—like getting hit in the mouth—or from long-term decay. The internal tissue breakdown releases pigments that cause the tooth to darken.
In these cases, a root canal may be necessary to remove the dead tissue and prevent infection. Once the tooth is treated, a dental crown or esthetic restoration can restore its natural color and appearance.
5. Swelling Near the Tooth or Jaw
Another common warning sign is swelling of the gums or jaw near the affected tooth. This swelling can feel tender to the touch, appear red or puffy, and may even produce a small pimple-like bump (called a dental abscess).
Swelling happens when infection spreads from the pulp to the surrounding tissues. The body’s immune system sends white blood cells to fight the bacteria, causing inflammation and sometimes fluid buildup.
If the infection progresses, it can cause facial swelling or a noticeable lump along the gumline. These symptoms should never be ignored—untreated abscesses can spread the infection to other parts of the body.
Our team at Sandquist DDS can gently drain the abscess and perform a root canal to clear the infection at its source, helping you feel comfortable again.
6. A Bump on the Gum
A bump on the gum that looks like a small pimple may indicate that an abscess has formed near the root of your tooth. This is often the body’s way of releasing pressure from an infection. The bump might ooze pus or come and go over time, but the infection underneath remains active.
This bump, known as a fistula, is a sign that bacteria have created a tunnel through the bone to the gum surface. A root canal is typically the best way to remove the source of infection and allow the area to heal properly.
If you notice any kind of bump, blister, or swelling near a tooth—especially if it’s paired with pain or discoloration—it’s important to contact your dentist right away.
Why Early Diagnosis Matters
Ignoring these signs can lead to more serious problems, including bone loss around the tooth or the need for extraction. The earlier you seek care, the more likely it is that your dentist can save your natural tooth through root canal therapy.
At Sandquist DDS, we use modern diagnostic tools like digital X-rays and 3D imaging to assess the health of your tooth with precision. Early diagnosis also helps minimize discomfort and reduce the need for more complex treatments later.
What to Expect During Root Canal Treatment
Many patients feel anxious when they hear the words “root canal,” but today’s treatments are far more comfortable than most people imagine.
During the procedure, Dr. Sandquist will numb the area to ensure you’re comfortable. A small opening is made in the top of the tooth, and the infected or inflamed pulp is carefully removed. The inside of the canal is cleaned, shaped, and sealed with a biocompatible material.
In most cases, a dental crown is placed over the tooth to protect it and restore full function. This crown also improves the esthetics of your smile, blending seamlessly with your natural teeth.
After treatment, mild tenderness is normal for a few days, but most patients return to work or normal routines right away. Over-the-counter pain medication usually manages any minor soreness.
How Root Canal Therapy Protects Your Smile
Root canal treatment doesn’t just relieve pain—it preserves your natural tooth, preventing the need for extraction and replacement. Keeping your natural teeth helps maintain proper chewing function, jawbone health, and overall esthetics.
In addition, root canal therapy prevents infection from spreading to other teeth or areas of the mouth. With proper oral hygiene and regular checkups, a tooth that has undergone a root canal can last for many years, even a lifetime.
