Visit your dental surgeon soon. Maintain good oral hygiene. Go to a proper dental clinic and don’t look for cheap dental treatment facilities or charitable type dental clinics. A specialist dental surgeon will examine you properly and give you genuine advise but these cheap dental treatment facilities will ignore your genuine problems and provide you treatment which is not required.

Hello If u r not feel any discomfort and pain Thn thr is very less chance of cancer but for proper diagnosis u have to visit physically

If you have had redness on your tongue for three years and it hasn't caused any pain or discomfort, it's less likely to be a sign of cancer. However, it's essential to consult a healthcare professional, preferably a dentist or an oral surgeon, to get a proper evaluation and diagnosis. Persistent redness on the tongue can have various causes, and it's crucial to determine the underlying reason for accurate treatment. Some possible non-cancerous causes of redness on the tongue include: Irritation: Certain foods, drinks, or habits like smoking or using tobacco can cause irritation and redness on the tongue. Allergies: Allergic reactions to certain foods, medications, or dental products may cause tongue redness. Oral Candidiasis (Oral Thrush): A fungal infection in the mouth can lead to red patches on the tongue and other areas. Geographic Tongue: This condition causes irregular, map-like patterns on the tongue's surface, which can include red areas. Vitamin Deficiencies: Certain vitamin deficiencies may lead to tongue redness or other oral symptoms. Oral Lichen Planus: A chronic inflammatory condition that can cause red or white patches on the tongue and other areas in the mouth. While these conditions are more common, it's crucial to rule out any potential underlying issues, including the possibility of oral cancer. Visiting a healthcare professional will allow for a proper examination and possibly additional tests, such as a biopsy if necessary, to determine the cause of the redness. It's understandable to be concerned about any persistent oral symptoms, even if they are not causing pain or discomfort. I strongly advise reaching out to a healthcare professional for an evaluation and appropriate guidance. Early detection and proper management of any oral health issue are essential for overall well-being.

Please share a proper picture. Do you have any habits?

Hi, Since you don't have any symptoms and you have been noticing it for 3 years, there is nothing to worry. But suggest you meet a dentist for a physical examination to rule out any problems.

If its been there for 3 years I don't feel there's much to worry. More so because you don't have any symptoms. But if in doubt then visit an oral medicine specialist for a physical examination
