Teeth / Gumline Staining

Hello Dr. Ellie,

You helped me out with some questions I had when first beginning your program 6 months ago. which I very much appreciated. I just recently had my 6-mo dental cleaning appointment, and the hygienist noted that I had some “black-line” stain, mostly on the inside tooth surfaces, which she was able to remove by polishing. Otherwise, everything was good. Could the stain be related to xylitol use? As far as I know, I have never had that particular staining before.


Hi G,

The use of my program using rinses and xylitol is designed to eradicate bacteria that pollute saliva.

These bacteria are the ones that form plaque when they stick to teeth.

It takes about 6 months to eliminate this infection from saliva – or “clean it”

Recently I have been using the analogy of a fish tank:

Your teeth are like stones in the fish tank.

Cleaning the stones is useless if the water in the tank is dirty and putrid.

Clean the water and then the “stones” will stay clean.

You have just cleaned the water in your mouth – by being on the program.

During the cleaning process – dead plaque on teeth will shrink down and form a band of staining.

Now in the future ( providing you are careful and keep the routine) you should not have more of this staining.

Your “stones/teeth” will stay healthy and clean. You have cleaned your mouth – and now you are ready for a future of oral health!

Congratulations – this is something you should feel very good about!

Thanks for your message,

Best Wishes,
