The Oral Health Non-Negotiables
Why this guide exists — and how to use it
Your mouth is not a separate system from the rest of your body. The same bacteria implicated in gum disease have been identified directly in arterial plaque, and chronic oral inflammation is increasingly recognised as a genuine cardiovascular consideration, not just a dental one. This guide covers the basics most people underestimate, and doesn't shy away from where popular dental advice runs ahead of the actual evidence.
This guide draws on the joint European Federation of Periodontology and World Heart Federation consensus report on periodontitis and cardiovascular disease, and the Cochrane Oral Health group's systematic reviews — including, honestly, the review that found less certain evidence for interdental cleaning than popular dental advice typically suggests.
The Non-Negotiables
| # | Non-Negotiable | Why it matters |
|---|---|---|
| 1 | Brush for the full two minutes, not 45 seconds | Most people brush for well under a minute — not enough to meaningfully disrupt the bacterial film that causes both cavities and gum disease. |
| 2 | Sugar frequency matters as much as total sugar | Sipping sugary drinks across the day bathes teeth in acid far longer than the same sugar consumed in one sitting. |
| 3 | Bleeding gums are a signal, not a normal state | Gum disease at the early, reversible stage is common and treatable — persistent bleeding beyond a week of good hygiene is worth a dentist visit. |
| 4 | Chronic gum inflammation is a genuine cardiovascular consideration | The association is well-established, even though the causal mechanism and whether treatment reduces cardiovascular events specifically remain active research questions. |
| 5 | Not every popular dental habit has the evidence its reputation suggests | Interdental cleaning has genuine, if more modest than commonly claimed, evidence — worth knowing precisely what it does and doesn't show. |
