Hi Dear, Welcome to Health Care Magic Team. Understanding your concern. As per your query you have swollen taste buds after swallowing ocean water . There can be many reasons for swollen taste buds like hot food , alcohol , smoking , infection , allergy , vitamin B and C deficiency and acid reflux . But in your case it seems to me that the swollen taste buds are either due to allergic reaction from sea water or infection caused by seas water . I would suggest you to do warm saline rinses several times a day , do betadine rinses twice a day , maintain proper oral hygiene , take benadryl twice a day and avoid hot and spicy food . If condition doesn t get better in few days then consult oral pathologist for proper examination . Doctor may prescribe antibiotics along with anti inflammatory drug . Apply orabase gel for pain . Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
