Suggest the cause for hole in the gum
Patient: I have a hole in my gum back behind my last molar on the upper right side of my mouth.  I have all my wisdom teeth still, my dentist said they didn't need to be removed.  I woke up one morning to find this rather large hold in my gum.  Just wondering what it is. Doctor: Hello, Welcome Thanks for consulting HCM,  I have gone through your query,  as you  have hole in gums behind last molar dont worry this can be due to periodontal pocket formation , or due to Caries in last molar tooth . Consult dentist and go for treatment if it is carious then go for restoration of tooth if it is periodontal problem then go for Currettage . Hope this will help you.
