[|Human|] Hi,I stopped wearing my retainer after my braces. I occassionally wear it and with no problem. This time, I have a problem with my gums nearest my tongue. My gums are looking swollen, red, a little black too. I was smoking cigarettes so Im wondering if I have a infection and now I should to my dentist?
[|AI|]  Thanks for your query, I have gone through your query. The swollen gums could be because of the gum infection secondary to the deposits over the teeth, or it can be secondary to irritation by the retainer. The black discoloration could be because of the calculus below the gums or because of physiological pigmentation. Consult your oral physician and get your teeth cleaned once and maintain the oral hygiene after that. You can use mouth washes. I hope my answer will help you, take care.
