I am 23 years old and I have recently had problems with a very weird sensation. After I floss or when I eat I have this feeling like my teeth are popping or clicking. It is very annoying but on top of that i am worried my teeth may be loose. It is mostly my top front four teeth. I have dealt with problems with gingivitis and I am worried that is part of the problem. I bleed alot when I floss and brush. I brush twice a day with an electric toothbrush but I slack sometimes on flossing. When I floss regularly the bleeding stops but it makes the teeth have the popping sensation more. How serious is this and can it be fixed? Other things of importance I should note is that I breathe through my mouth a lot so my mouth stays dry, I wear a retainer at night and while dentists say I should floss more they never seem worried about my teeth but I have not been back since the popping started. Any help you can provide would be greatly appreciated. Thank you for your time!
