Dental Oral care is essential.
I am just over 1 1/2 years out and have had numerous issues with the teeth.
Just after treatment I was told to do the fluoride trays but even with that I was having my teeth decay at alarming rates. I saw a doctor of oral medicine and he is having me use a few other things to try and keep the decay from coming so quickly.
Saliva keeps and helps decay from taking place so when the saliva is eliminated decay comes quick.
I was told to brush my teeth immediately after every meal
Use a prescription fluoride toothpaste
use a bacterial rinse, I use a prescription called peridex
use a calcium paste which helps your teeth maintain the calcium levels
use fluoride trays nightly
Dental Issues are something that seems to be an ongoing issue and I guess will always be but extra care is needed to maintain teeth.
Good luck and keep up the good work
