Re: Slightly loose teeth
When you go to the dentist, have them measure the amount your gums have receded. They'll take a little measurement thing, and go between each tooth, and call out numbers like 2,3 - 3,4 ect. (this is millimeters, i think). It doesn't hurt a bit, its just measuring. I was told that any 7's or above was too far receded, and would not come back. I had one 5,6, the rest were 2,3's and 3,4's. I was then told (after my cleaning) that if I began to floss every day and use listerine rinse they would come back. I did, and sure enough I have much healthier gums. Pink and healthy and growing back up around my teeth where they should be.
Get the measurements done, and a cleaning, and brush, floss and do a 30 second listerine rinse every day (the natural citrus tastes the best, and doesn't burn as much) and your gums should improve.
Congrats on quitting smoking! Thats a tough one, and thats the habit that is worst on your gums.
Good luck, and let us know what happens
