Patient's Query

Hi doctor,

I have a red patch inside my cheek that can be seen only with bright light. It is painless and feels like sandpaper when I put my tongue on it.

Thank you.

Welcome to icliniq.com.

I have seen the lesion, and because the photo (attachment removed for patient identity protection) is without any flash, you will have to tell me whether this sandpaper feeling you are having is throughout the inside of the cheek. Also, when was the last dental visit you had?

Have you had any dental procedures or filled teeth in the upper or lower teeth?

Not all lesions are precancerous or cancerous; most are inflammatory and harmless. If you let me know how you feel, the extent of the lesion when you touch your tongue, and your past dental history, I will suggest remedies after I diagnose. You should probably start rinsing your mouth with Chlorhexidine gluconate mouthwash at night, and lukewarm salt water five to seven times which will help. However, these are insufficient to remove the lesion, and for any topical or oral application, I need to diagnose you first.

Thank you.

Patient's Query

Hi doctor,

Thank you for your response.

My last deep cleaning was around three months ago. I had periodontitis treatment around three years ago and cleaned every three to four months.

The lesion is felt with my tongue inside the cheek just under the upper left teeth and a bit below. If I do not use my tongue, I do not feel it and forget about it most of the time. I smoke daily, and I do not know if it is related, but I have a fungal rash on my neck, which is going away with treatment (cream). I did not have any dental procedures over the last year or had any pain, only the occasional gum bleeding when I brushed my teeth due to the mild gum disease. These gum problems I have are most probably due to smoking. I hope this helps to make a diagnosis.

Is anything else needed?

Thank you.

Welcome back to icliniq.com.

That was a good explanation. It certainly helped. I got an idea now. When did you get this fungal rash on your neck?

You observed this lesion also post this infection only, right?

I want to know which cream you are applying to your neck. I will suggest and change accordingly to eliminate both infections simultaneously if they are interlinked.

I know quitting smoking would be challenging, but that makes you more predisposed to develop precancer lesions quickly. I have an effective remedy that I can give you, but you need to reduce the number of smokes at least every day.

Please tell me the brand of the anti-fungal gel you are using and when did this rash on the neck occur?

Thank you.
