About Know Your Mouth

What this site is

Know Your Mouth publishes plain-English explanations of ordinary dental questions — why breath goes bad, what bleeding gums mean, whether the whitening trick you saw online does anything. The aim is to answer the question properly and then stop, including when the honest answer is “the evidence here is thinner than people claim”.

What we are not

This is the important part, so it goes near the top rather than buried in a footer.

• We are not dentists. Nobody writing here holds a dental or medical qualification. We are not able to diagnose anything, and we do not try to.
• This is not medical advice, and it is not a second opinion. It is general information, written carefully, by people who read the research rather than people who treat patients.
• We have not tested any product in a laboratory. When we review something, we are analysing publicly available information about it — not measuring it.

If you want to know what is happening in your own mouth, you need someone who can look at it. Nothing on this site is a reason to delay that.

Why you should read us anyway

Because a lot of what is published in this niche is worse. Search almost any dental question and you will find pages assembled to rank, stuffed with claims nobody checked, pointing at a supplement. The bar we are trying to clear is simply: say what is actually established, say what is not, and be explicit about which is which.

Where we make a claim that matters, we say where it comes from. Where the research is weak, we say it is weak — even when a stronger claim would sell better. Our review method sets out how that works in practice.

How the site makes money

Affiliate commission, from exactly one product. Our ProDentim review contains an affiliate link, and if you buy through it we earn a commission from the seller at no extra cost to you. That is the only affiliate link on the site — no article contains one.

We would rather tell you that plainly than have you work it out. The full terms are in our affiliate and health disclosure.
