Can anyone shed any light on what this could be ?

How did you get on at the dentist 

Hi , thanks for asking . Yes I got on fine . He doesn’t think it’s anything to worry about but told me that if it changes colour or anything to go back but I’ve arranged another appointment for 2 months time . He thinks it’s a salivary gland so I feel a little better about it but it’s still there so he did say he could refer me which I will if not gone in a couple of months . 

Thank you for asking
