Mouth Care System

Dr. Phillips,

I have been using the Zellies mouth care system for a while now (maybe a year or so?), and something is happening that is worrying me. I have brown patches on a few of my lower teeth. I have never had this problem before I started using the system. Do you have any idea what might be causing this?

Specifically, the inside of my left lower tooth (incisor?) has brown where the curve is (like a u shape). Also, there is brown between a couple of my lower front teeth. The teeth appear to be totally clean (like never before!), yet this brown stain has appeared.

I was wondering which element of the mouth care system whitens the teeth?

Thanks for any insight.


Hi E,

The problem of staining is a great discussion!

The link below will take you to a time line – showing the various stages when you use xylitol and the rinse system.

You will see that it takes some months for the sticky plaque bacteria on your teeth and in your saliva to “die off”.

If these bacteria are attached to the soft cementum or stuck between teeth – they can die off and may not get washed away.

Then can remain stuck to the tooth surface as a dark stain – waiting for your next dental cleaning to remove them.

This stain is dead debris – harmless – but it looks annoying.

Think of it as dead leaves that fall off trees in the fall.

I am trying to figure out a way for people to safely remove this stain for themselves – but I have not managed to figure out a way to do this yet.

It is superficial but stuck very tight.

Here is the timeline: 

This stain that you see is dead stuff – and your gums will now be healthier because the plaque has died and gone. Once this stain is removed – (if you stay on the system) – it will stay gone!

Below is the description from my website (under the Complete Mouth Care System).

If you follow the link you will see a graph showing how xylitol works and a discussion about this stain (at the bottom of the page). 

Most people notice a cleaner, fresher mouth within the first week of using Zellies Complete Mouth Care System. As plaque bacteria absorb xylitol, they become less sticky and usually are easily brushed off teeth with a toothbrush.

If you have routine plaque and tartar, you will begin to notice a difference in your oral health in about 5 weeks, as harmful plaque bacteria are removed from the surfaces of teeth. After 6 months, you should have your teeth cleaned in a dental office.

If you have heavily infected plaque deposits when you start using Zellies Complete Mouth Care System, dead bacteria may form a dark band of stain along the gum line. It can be easily cleaned off your teeth at your next dental cleaning and is unlikely to return if you remain on the system.

Hope this puts your mind at rest!

Let me know if you have any other questions,
