I believe that your dentist was absolutely correct.

Plaque is layers of infected bacteria interwoven with fibers that stick to teeth. Eating xylitol regularly changes the bacteria in your mouth and removes all the infective, sticky ones but this process takes most people about six months.

Until you reach this stage, the dead sticky plaque has to go somewhere and it appears to shrink down into a band of staining that may end up around the gum margin of your teeth. This is nothing to be afraid of it is a good sign that your mouth is becoming cleaner and healthier.

You should celebrate the fact that all the bad stuff has shriveled up and gone from your teeth!

If you continue eating sufficient xylitol you will probably find that you do not have any of this staining at all. If you slack off and let plaque build up again the band of staining may reoccur (but a simple and quick cleaning at the dentist will put you back to white and shiny). I would imagine that despite this surface “staining” your dentist was pleased with the condition of your teeth and gums?

People who normally worry about stained teeth are looking at a different problem. Most teeth stain because they are soft and porous. Everyone should be concerned about the yellow staining of soft and porous teeth.
This mouth rinse system toughens teeth up to prevent this kind of staining it makes teeth whiter, stronger and shinier.

Personally I would not stop anything unless you believe your teeth were better before you started the system.
If this is the case, I would like to make sure that you have the process correct and are not using other toothpastes like Sensodyne or Crest Pro Health by mistake. Crest Pro Health contains stannous fluoride which does stain teeth this is a paste I would not recommend. I only recommend the basic Regular Crest paste.

This staining should not keep happening if you make sure you enjoy adequate amounts of xylitol and use the rinses twice a day (always before bed at night). Our battle against mouth bacteria is constant which is why almost all adults are eventually overwhelmed and have gum disease and dental problems. Mouth bacteria are always growing and attacking they double in numbers ever ten minutes.The Complete Mouth Care System is amazing in the way it controls such a huge problem.

If you continue with the program you should see very different results as time goes on with your teeth feeling cleaner , more comfortable and shinier.
Good luck and thanks for the update!
