Is my mouth sore a sign of oral cancer?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I have pain in some tooth on the right side of the jaw. I went to a dentist, and the doctor did an X-ray. The dentist concluded that it is probably due to clenching or grinding of the tooth. He suggested me a mouthguard. I have given impressions for a mouth guard. But still, I have mild pain.

For a few weeks back, I have realized that I am biting the inner part of the cheek and tongue. After a week, I had an ulcer or sore in my mouth. It does not get healed. I saw a doctor again, and he prescribed me Orajel and an antifungal mouth rinse.

I have attached the images of the mouth sore which is not healing.

  1. Could you please take a look at the picture of the sore on my inner part of the mouth?
  2. Please suggest me whether it is the first sign of oral cancer.
  3. Do I need to get screened?
  4. How long should I have to wait for the mouth ulcer or the sore to get healed?

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I have gone through the images (attachment removed to protect patient identity). It looks like a well indurated mucosal ulcer. Being oral cancer is unlikely. Please mention about your habits regarding tobacco chewing or any other habit. Generally, oral ulcer takes three to four weeks to get healed. It depends on the cause. There are multiple causes such as vitamin deficiency, iron deficiency, viral and other immunocompromised diseases.

Do CBC (complete blood count), VDRL (venereal disease research laboratory test), vitamin B12, and folic acid. Revert me with the reports. Continue using an antifungal mouth rinse, use Orajel (Benzocaine) and take B complex tablets daily for 15 days.

I hope it helps.

Thank you.

Patient's Query

Hello doctor,

Thank you doctor for your reply.

I do not have a habit of tobacco chewing. I was a smoker, and I have quit it. I never had unprotected or protected sex. I will do these tests soon, and I will get back with the results soon.

I did a blood test last year, and the result showed vitamin B12 deficiency. I was taking a supplement for it. I continue using a mouth rinse, Orajel, and capsule Nutrolin.

Please help,

Thank you.

Hi,

Welcome back to icliniq.com.

Along with the above tests, start taking tablet Folic acid 5 mg once a day and B complex tablet one tablet twice a day. Revert me with the reports after two weeks.

I hope it helps.

Thank you.
