For the past year I keep getting random soreness in my gums. I’ve been to the dentist several times and they advised that my teeth are completely fine even after taking x rays. I’ve been given antibiotics which I took and it helped however the soreness comes back after a couple months. The dentist has just advised to brush and floss which I do everyday. My general diet is healthy with clean foods and I do not smoke. Does anyone have any advice please? Shall I visit another dentist maybe?
