Thanks for asking the query,
White spot on the tongue can be due to ulcerations.
Oral ulcerations are caused due to deficiency of vitamin B specially B3 and vitamin C
, Pernicious anaemia can also be the reason. So please rule out by taking blood test
and approaching the physician
ointment 1.5% cortisone acetate
topically over the affected area.
Use vitamin suplements , please avoid intake of hot and spicy food.
Use saline water gargles 3-4 times a day, this will give a soothing effect.
Use antiseptic mouthwash solution like chlorhexidine
Take balanced diet, fruits like oranges, carrots, green leafy vegetables.
Drink plenty of water and keep yourself hydrated.
Hope this helps out.
