The thought of a root canal often makes many people uneasy, but ignoring warning signs can lead to more pain, infection, or even tooth loss. At Sai Yashoda Dental Care, we believe in early detection and gentle treatment. Here are five signs you should watch out for — if you notice any of them, it may be time to consult us for a root canal evaluation.
1. Intense, Lingering Tooth Pain

Do you ever experience sharp, throbbing pain when biting down, or lingering discomfort even after the bite is released? That kind of deep pain, especially if it lasts for hours or wakes you up at night, often means the inner pulp (the soft tissue inside your tooth) is inflamed or infected. It’s one of the most common signs that the pulp may be damaged beyond simple repair.
2. Sensitivity to Hot or Cold That Doesn’t Go Away

Everyone gets sensitive teeth now and then, but when cold drinks or hot foods cause pain that lingers long after the stimulus is gone, that’s a red flag. If your tooth hurts for several minutes (or more) after eating ice cream, sipping coffee, or drinking hot soup, it could mean the nerve is being compromised.
3. Swelling and Tenderness Around the Tooth
Inflammation doesn’t always stay hidden. Swelling of your gums, face, or even jaw near the problem tooth—especially if accompanied by tenderness to touch—can signal that bacteria have penetrated deep into the tooth. Sometimes a small bump (abscess) forms on the gum near the tooth root. These signs mean the body is fighting infection, and delaying treatment could allow it to spread.
4. Discoloration of the Tooth

If a tooth starts looking darker—grayish, brownish, or even strangely yellow compared to the teeth around it—it could mean that the pulp inside is dying or already dead. When blood vessels inside the tooth break down, the tooth may lose its healthy color. Discoloration on its own isn’t always proof, but combined with other symptoms, it’s something your dentist will want to check.
5. A Bad Taste or Foul Odor in the Mouth
An infection inside a tooth sometimes leads to drainage (pus), which may cause a bad taste or persistent foul odor, even with good oral hygiene. You might also notice swelling in your face or jaw, or feel generally unwell (fever). These are serious signs and should not be ignored.
What to Do If You Notice These Signs
- Don’t wait: The earlier an infected or inflamed pulp is treated, the better the chance of saving the tooth and preventing complications.
- Contact Sai Yashoda Dental Care: At Sai Yashoda Dental Care, we don’t just rely on routine check-ups—we use cutting-edge technology to give you the best care possible. Microscope-enhanced dentistry helps us handle cases with excellent precision by providing clear visual information, magnification up to 15–25X, and greater accuracy. Whether it’s detecting hidden cavities or performing delicate root canal treatments, this technology ensures we minimize errors and deliver long-lasting results.
Understand the treatment: A root canal involves removing the infected pulp, cleaning and disinfecting the inside of the tooth, then filling and sealing it. In many cases, we restore the strength of the tooth with a crown to protect it long-term.
