<s>[INST] Hi,I have a recently developed a hole in the back left of my gum.  The hold is directly below the left bottom moler.  It does not hurt.  I have not had my wisdom teeth removed yet, I am 23 years old.  Is this something I should be worried about?  What are the next steps?Thanks! [/INST] Hello, Welcome Thanks for consulting HCM,   I have gone through your query, as you have hole in gum it can be formation of sinus opening or due to Initial caries .  For this you should consult dentist and go for investigations IOPA xray done if it is proximal caries then go for Restoration or if it is  Pericoronal Abscess then go for Scaling and root planning.  Hope this will help you. </s>
