Yes, I have a few years ago. One deep pocket that was always infected when I came in for my 3 month cleanings.
For after care, i followed the Dentists reccomendations completely but the pocket just kept getting worse.
I swear, everytime I would go in for cleaning, they would tell me I need to do more brushing, flossing, use a sonicare, a waterpic, a oral rinse.
Everytime I followed their instructions, my teeth only got worse.
Now I still have that big deep pocket and the gums have not grown in at all.
I believe there must be a better way. Do more research online and make up your decision. But please, try and find a dentist who will check out your teeth with a microscope. I wish I had known about my options at the time.
Good Luck
