What are the causes for a white patch on the edges of the tongue?

Hi, Welcome to icliniq.com.

I read your query and understand your concern. I empathize with your concerns about the dead skin patch on the lateral tongue border. I have examined the picture (attachments removed to protect the patient's identity). Please answer a few questions- Did you ever go to the dentist and get this patch examined before? Have you undergone any dental treatment before? I need your dental history if you would elaborate on it a bit. This can happen for several reasons that cause the tongue epithelium or skin to become thickened. It might be due to a weak immune system, rarely some forms of precancerous lesions that are pretty harmless unless provoked, vitamin deficiencies, and smokers and alcoholics. I suggest you to give me your dental history first so I can formulate an exact treatment plan for the non-surgical elimination of this white lesion. Simple strategies that I can suggest you to reduce the thickened patch are as follows- You must use lukewarm salt water rinsing six to seven times a day and You can use Chlorhexidine Gluconate 0.2 % mouthwash every night for three months. You can also apply Choline Salicylate gel with Lidocaine 2 % gel combination for 15 days on the lesion.

Thank you.
