Science, trends, products & the weird stuff in between

Mouthful covers teeth, gums, breath and everything they quietly connect to — sleep, medication, money, the stuff nobody brings up at a checkup. Some of it is settled science. Some of it is whatever the internet decided last month. We're interested in both, and in telling you which is which.

What you'll find here

• Explainers that answer the question you actually typed, in the first paragraph.
• Product talk — what's worth it, what's marketing, what's the same thing in a nicer tube.
• Trends, tested against the evidence rather than repeated.
• The odd stuff — the habits, myths and hacks people swear by.

How we write

No lectures. No paragraph of throat-clearing before the answer. If the honest answer is "we don't know yet", that's what it says.
