Hi,
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
Apply
steroid 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 twice daily
Take balanced diet, fruits like oranges, carrots, green leafy vegetables.
Drink plenty of water and keep yourself hydrated.
Hope this helps out.
Regards.
