Hello,
After a tooth extraction, it’s quite common to notice increased saliva and some changes in the mouth during the healing phase. From the picture and your description, the white patch on the tongue looks like it could be due to coating, mild fungal overgrowth, dehydration, or irritation, which can sometimes happen after dental procedures, medications, or reduced oral intake.
This is usually temporary and not directly related to the extraction site. Maintain good oral hygiene, gently clean your tongue with a tongue cleaner, drink plenty of water, and avoid spicy or very hot foods for a few days.
For now, there is no cause for immediate concern 🙂
Next Steps
Maintain good Oral hygiene and try to intake more water and healthy food for better recovery.
Health Tips
If the white patch does not reduce, becomes painful, starts spreading, or if you notice burning or altered taste, it would be best to visit a dentist for a clinical examination and medication if required.
