Covid tongue. To consult other doctor?

I have a frequent small scratch on left side edge of tongue , place is not the same. Experiencing since 3,4 months, it heals in 2,3 days. No pain and burn. Visited to the dentist in my sector, prescribed for biopsy and head and neck surgeon, visited to head and neck ENT surgeon, doctor prescribed for dentist surgeon as G18 teeth is causing the same. So need to treat the teeth and said no biopsyis required, visited to the famous dentist surgeon he listen my all the stories, checked the teeth said nothing is sharp, but he treated the teeth as suggested by ENT surgeon also he treated other teeth as he felt. Doctor said don't go for biopsy if you go it worst your condition. This is happening because you had covid, called covid tongue and it takes time for complete recovery. Take lots of fruits and water no medicine. Just want to know do i need to consult other doctor
