From the description and the photographs, the white spot on the tongue appears to be mild, stable, and asymptomatic, as there is no pain, burning sensation, or change in size over the past few months. Such white patches can commonly be due to normal variations in the tongue surface, mild keratinization, or local friction and are often harmless.
If the spot is not increasing in size, not becoming ulcerated, not causing discomfort, and not associated with bleeding, it is usually not dangerous. Many such spots can remain unchanged for long periods or even lifelong without causing any problem.
Next Steps
At present, there are no warning signs suggestive of a serious condition. However, as a precaution, it is always advisable to:
Get it clinically examined once by a dentist/oral surgeon
Maintain good oral hygiene
Avoid tobacco, smoking, and excessive alcohol (if applicable)
If at any time the spot changes in size, color, becomes painful, or starts ulcerating, then further evaluation may be required.
