Hi and welcome,

sore tastes in the mouth is may be due to underlying oral infections , gingivitis , decayed teeth.

Improper brushing and tongue cleaning , flossing and poor oral hygiene may also lead to inflammation of oral tissues and bad taste.

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.

i hope this helps ,

take care.
