Hello sir / madam I have gap in my front two teeth,one dat while just having a look on my upper gums I stretched my frenum and it showed a white cyst kind of thing which went back to normal when I relaxed my frenum, I consulted my dentist for the same He told me that these are the upper tissues of the frenum that have hardened because of gap in the front teeth because of which you have a large frenum too. I wanted an advice on the same that is there any ointment or something, I was also worried about mouth cancer because I had a habbit of smoking which I had quit one month ago. I want to inquire on the same too.  This is white and not yellow as in the picture.
