Hello there ,
Thanks for writing your query,
Recurrent trauma to the tongue mucosa due to impingement of chipped tooth has lead to formation of ulceration in your case .
Appearance of recurrent ulcers on the oral mucosa
like tongue mucosa indicates inflammation .
It may be caused due to several reasons like deficiency or certain vitamins especially vitamin B12
and vitamin C.
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.
Apply oral antiseptic ,analgesic
ointments like dentogel or mucogel topically over the affected area
i hope this helps ,
