Fluoride and Tooth Erosion?

Hi Dr. Ellie,

I’m considering starting your system be case my teeth they are eroding badly and I’m only 20 so I’m desperate.

I’m concerned about the fluoride, from what I’ve read from natural health experts is it fills in teeth making them more brittle? I really don’t want my teeth to get any weaker. Does the fluoride fill the teeth or does it help other minerals like calcium/phosphorous go into the teeth?
Do you notice in any of your patients that their teeth are more prone to cracking, weakening, cavities, and chipping after going on the CWT system? Do yo have patients with dental erosion improve after going on the system-do you see the change-less yellow?



Hi C,

Thanks for your message.

I do hope you will try my system it will definitely help you, and it sounds as if you desperately need help. If your teeth are eroding badly you should try to figure out why.

It is always acidity and/or dry mouth that cause problems. Whitening strips are very acidic and can be a real problem but so are lots of other things including soda drinks, red bull, lemonade, Gatorade, etc etc. The list is almost endless when you start finding out how acidic most drinks are.

Once you have understood the reason for erosion then you will be able to protect your teeth from this damage. If you need help trying to figure out what is the cause then I would be happy to help you.

People who use the CWT system find that sensitivity usually ends within a week. Teeth start to feel smoother and gums are definitely more comfortable. The color of teeth takes longer to change and you have to become confident for a while and stop peering into a bathroom mirror!

If you listen to stories about fluoride, then you will have teeth that look like the teeth of those people telling you the stories. I always suggest checking the teeth of people giving you dental advice! Many so-called dental experts do not have particularly healthy-looking teeth (if you get my gist!)

On the other hand, I would never suggest that anyone ingest artificially fluoridated water for example. I am very worried that most people in America are consuming far too much fluoride and they do not even know it. Tea leaves are often sprayed with fluoride – and something like iced tea can contain a substantial amount of fluoride, because the mixture is concentrated and then reconstituted with fluoridated water.

If young children consume too much fluoride it becomes a problem as their teeth are forming in the jaw bones. The most damage occurs when fluoride supplements are given to children around the ages of 2 and 3 years old. The permanent front teeth are growing in the baby jaws at this time and their “enamel-forming cells” can easily be poisoned by fluoride in their system.

This is why we no longer recommend fluoride supplements for children and dentists do not recommend fluoride oral care products for children until they can rinse and spit and avoid eating toothpaste!

As an adult these problems cannot occur. Your teeth have finished forming and the enamel-producing cells are gone. Even so, I do not recommend consuming fluoride (for many other reasons) but I do recommend rinsing with a dilute solution of sodium fluoride.

I am very picky about the kind of fluoride in this rinse it must be sodium fluoride. I am also very picky about the dilution that you want nothing stronger than 0.05%. Stronger fluoride is not better in fact, instead of helping teeth harden and shine, stronger fluoride will not achieve this effect.

I hope this allays your fears and I really hope you will go ahead and try the system.
I would love to know how you care for your teeth now toothpaste, rinse etc.

    I’ve got a querstion about your comment on the whitening strips. You mention that they are acidic to litmus but the most of the strips that I am looking at (mostly Crest) contain sodium hydroxide. This is a strong base. What other ingredients do whitening strips contain that would cause them to make litmus turn acidic?

    I have a question about the chipping. After using the system for 2 1/2 months, I noticed a chipped area on the face of one of my front teeth – almost like a dent in the tooth. I think before I started the system there was a small white spot there but not this chip. I'm concerned, am I doing something wrong?Thanks so much for your time and for this blog.

    Thank you for replying. That makes sense but I'm sorry to say that I don't have a camera. I'll see if maybe I can get someone to do that for me.
