Actually, research implies the opposite conclusion may be true and overcleaning your mouth may increase disease risk.
I’m guessing it might be explained by the hygiene hypothesis.
The oral microbiome needs balance, not sterilization.

- notmyjob 1y agoPeople lie about smoking and drinking also use mouthwash to help conceal their secret(s). Plausible?
- Jimmc414 1y agoYes, thats plausible and the INHANCE consortium even suggested this. However the mechanism for the effect on BP can be explained by antiseptic rinses impairing the nitrate‑nitrite‑NO axis

- notmyjob 1y agoKissing a middle age woman (or other high risk person)? Very true, but it antecedes as often as it succeeds kissing, depending on whether it antecedes or succeeds marriage vows. Ever smell a husband’s breath?
- HPsquared 1y agoI wonder how many mouthwash users do so because they are trying to compensate for another issue.
- TaupeRanger 1y agoThe research doesn’t really imply any conclusion. You can’t cherry pick 4 studies that show an association (not causal connection) and use it as a plausible argument.
- Jimmc414 1y agoFair point about association vs causation. To clarify, these studies don’t prove mouthwash causes these conditions, but the pattern across multiple independent studies in different populations suggests we shouldn’t assume ‘more cleaning = automatically better.
