Appearance of red spots on the oral mucosa
like roof of the mouth , tonue and throat indicates inflammation .
Appearence of inflammed taste buds indicates inflammation of tongue mucosa and it may be caused due to several reasons like deficiency or certain vitamins especially vitamin B12 and vitamin C.
Maintain good oral hygiene
by practising regular mouth rinsing with lukewarm saline water or antiseptic mouthwash like betadine or chlorhexidine
start with multivitamin
supplements for 7 to 10 days and vitamin C lozenges will help in resolving the problem.
avoid alcohol , carbonated drinks , tobacco chewing
and smoking as these may worsen the area affected.
you can apply topical oral antiseptics like dentogel over the affected which helps in giving soothing effect and reduces burning sensation.
i hope this helps ,
