Hi doctor,

I noticed the side of my cheek started hurting two days ago, and I got scared today when I looked carefully back there and noticed this white spot. Please see the attached photo. I looked it up online, and they trained about oral cancer. What do you think it is? Please see the attached pictures, one from the morning and another after lunch brushing my teeth. Kindly help.



Welcome to icliniq.com.

I have gone through the images (attachment removed to protect the patient's identity) you have enclosed. It looks like an inflamed, red and white lesion of the cheek mucosa near the molars, but definitely, some lesions may be precancerous rather than cancerous, like leukoplakia or red and white lesions (self-limiting), which means they should disappear in a few days with the strategies I recommend. Start with lukewarm salt water, rinsing multiple times a day, and use Chlorhexidine mouthwash at night for around two to three months. However, I would like to ask you a few questions to help me diagnose correctly: when did you notice this lesion? Only from two days, or was it there previously? Does the lesion feel hard, or is it just like a patch on the cheek mucosa? Any history of smoking or alcoholism? Your answers will help me diagnose this lesion more accurately and give you any antibiotic prophylaxis or next step such as biopsy if needed.

Thank you.

Hello doctor,

Thank you for the response. I first noticed the lesion two days ago. It feels like a patch on cheek mucosa. There is no history of smoking or alcoholism. I noticed it first two days ago. My mouth was hurting in the morning, and I noticed a small bruise on my tongue. I looked with a flashlight and saw this spot near the upper wisdom tooth molar.

There is no need to worry then. Please observe this lesion for around seven days. If it does not disappear even then, you will need to get this physically examined by the dentist. What I wanted to know mainly was, is that patch painful or painless? Please let me know that. You can start now by applying Dentogel or Dologel CT (Choline Salicylate and Lidocaine) to the lesion. Continue salt water rinse several times a day and Clorhexidine mouthwash at night or twice daily after brushing. Do not brush that area too vigorously. Use an extra soft toothbrush. Please let me know if that patch area is hurting?

Thank you.
