Tooth pain can be tricky. Sometimes it’s caused by something simple, like sensitivity to hot or cold foods. Other times, it can be a sign of something more serious – like an infection deep inside the tooth. When this happens, a root canal may be the treatment that saves your natural tooth.
At Dental Professionals of Dardenne in Dardenne Prairie, MO, Dr. Michael Gulley, Dr. Edward Logan, and our experienced team provide gentle, effective root canal therapy designed to relieve pain and restore oral health. But how do you know if you might need one? Here are the top signs to watch for.

1. Persistent Tooth Pain
Ongoing tooth pain is the most common symptom that something is wrong. If the pain is constant, throbbing, or worsens when you bite down, it may indicate that the pulp – the soft inner tissue of your tooth – is infected or inflamed. Unlike occasional sensitivity, this pain usually does not go away without treatment.
2. Sensitivity to Hot or Cold
Most people experience mild tooth sensitivity now and then. But if your tooth hurts long after you sip a hot coffee or bite into ice cream, it may mean the nerves inside are damaged. Lingering sensitivity is a strong indicator that the pulp is compromised and may require endodontic care.
3. Swollen or Tender Gums
Infection inside a tooth can spread to the surrounding gum tissue. If you notice swelling, tenderness, or a small bump near the affected tooth, it could be an abscess – a pocket of pus caused by infection. Abscesses are serious and should be treated right away to prevent the infection from spreading.
4. Tooth Discoloration
When the pulp inside a tooth becomes infected, it can cause the tooth to turn gray, brown, or black. This discoloration happens because the inner tissue is breaking down. If one tooth looks darker than the rest, especially in the front of your smile, it’s worth getting it checked.
5. Loose or Wobbly Tooth
As infection weakens the bone and ligaments around a tooth, the tooth may start to feel loose. This is a sign that the infection has progressed and needs immediate attention. A root canal can often save the tooth before extraction becomes necessary.
6. Jaw or Facial Swelling
In severe cases, infection inside a tooth can spread beyond the gums, causing swelling in the jaw, cheek, or even the face. This situation should never be ignored. Contact a dentist right away if you notice swelling, as it can quickly become an emergency.
Why a Root Canal May Be Necessary
Root canal therapy is designed to remove infected pulp, clean the inside of the tooth, and seal it to prevent future problems. The procedure allows you to keep your natural tooth, avoiding the need for extraction and replacement options like bridges or implants.
Thanks to advances in modern dentistry, root canals are now no more uncomfortable than a filling. At Dental Professionals of Dardenne, we use gentle techniques and local anesthesia to ensure your comfort.
What Happens During a Root Canal
If Dr. Gulley or Dr. Logan determines that a root canal is the best solution, here’s what you can expect:
- Diagnosis & X-Rays – We take digital images to see inside the tooth and confirm the infection.
- Numbing & Comfort – Local anesthetic ensures the area is fully numb before treatment begins.
- Cleaning the Tooth – The infected pulp is carefully removed, and the inside of the tooth is disinfected.
- Filling & Sealing – The space is filled with a biocompatible material and sealed to prevent reinfection.
- Restoration – In most cases, a dental crown is placed on the tooth to restore strength and function.
What If You Ignore the Symptoms?
Delaying treatment can allow infection to spread, causing bone loss, abscesses, and even systemic health issues. In many cases, extraction becomes the only option – which means added cost and the need for replacement solutions. Addressing symptoms early gives you the best chance to preserve your natural tooth.
