Oral Pathology: When a Sore or Spot in Your Mouth Needs a Biopsy

Most sores and spots in your mouth are harmless and go away on their own. A few need a closer look. Here is how to tell the difference and what happens if a biopsy is recommended.

1. Spots That Are Usually Harmless

Canker sores, a spot where you bit your cheek, irritation from a sharp tooth or a denture, and small smooth bumps are very common. Most of them heal or stay the same size for years without causing trouble.

Question to Answer: Can you link the spot to something like a bite, a burn, or a rough tooth?

2. The Two-Week Rule

A good rule of thumb is that any sore, patch, or lump that has not healed in about two weeks should be checked. Most still turn out to be harmless, but two weeks is long enough that it is not just a simple irritation.

Question to Answer: How long has the spot been there?

3. Warning Signs to Take Seriously

• A white or red patch that does not rub off
• A lump or thickened area in your cheek, tongue, or gums
• A sore that bleeds easily or keeps coming back in the same spot
• Numbness in your tongue, lip, or chin
• Trouble swallowing or a feeling that something is stuck

None of these means you have cancer. They do mean you should have it looked at soon.

Question to Answer: Do you notice any of these signs?

4. What Happens at the Evaluation

Dr. Chaliff looks at the spot, feels the area around it, and asks how long it has been there and whether it has changed. Bring your referral if your dentist sent you, and any photos you took of the spot over time. Many spots can be diagnosed just by looking. If not, he will recommend a biopsy.

Question to Answer: Do you have photos showing how the spot has changed?

5. How a Biopsy Works

A biopsy takes a small piece of tissue so a pathologist can look at it under a microscope. The area is numbed, the sample is removed, and a few small stitches are placed. It usually takes only a few minutes.

You can expect some soreness for a few days. Results usually come back in about one to two weeks, and Dr. Chaliff will go over them with you.

Question to Answer: Do you know when and how you will get your results?

6. Lowering Your Risk

Tobacco and heavy alcohol use are the biggest risk factors for oral cancer. HPV and years of sun on your lips play a role too. Regular dental checkups are one of the best ways to catch changes early, since your dentist looks for them every visit.

Question to Answer: When was your last dental checkup?

In Summary

The main takeaway is that most mouth sores are harmless, but anything that has not healed in about two weeks deserves a professional look. A biopsy is quick and gives you a clear answer. Learn more about oral pathology evaluations with Dr. Chaliff.
