September 2025 Email Exchange with Founder & CEO of Davids Toothpaste

Published: October 9, 2025

Below is the September 2025 email exchange I had with the owner of Davids toothpaste. First, there is an image of each communication, followed by the text for that communication (with clickable links) for those using a text reader. Thanks for reading! Frankly, I was flabbergasted by Eric’s interpretation of the FDA’s language — reminding me of the following Upton Sinclair quote:

Eric Buss’ September 9, 2025 email to me:

Here’s the text from the above image (which is a screenshot of the email, exactly as sent to us):

Hi Tamara,

On your website, you state the following….

“Remember: All relevant federal agencies agree there is no safe level of Lead exposure for children (and all humans, for that matter).”

Can you please send me links to each of the agencies you are referring to where they make this statement. I am aware that the FDA states that there is “no known safe limit for lead”, which is them admitting that they simply do know what is safe or not, but I am unaware of any agency stating that “there is no safe limit”.

Would love to understand better where you are coming from.

Thank you,

Eric Buss // founder & ceo

But really – watch my film. Then let’s talk on the phone. I will be happy to answer any questions for you. You need to re-evaluate your hydroxyapatite, hydrated silica and calcium carbonate (if you use those ingredients in your products).
