The Routine That Actually Works
The practical version, before the evidence
1 min read·Updated July 2026
If you want the practical version before the underlying evidence, this is it. Everything here is explained and cited properly in the sections that follow.
| Habit | Frequency | Why |
|---|---|---|
| Brush with fluoride toothpaste | Twice daily, 2 minutes each time | Disrupts the plaque biofilm that causes both cavities and gum disease — most people brush for well under a minute, which isn't enough |
| Clean between teeth | Daily | Reduces gingivitis and plaque per controlled trials, though not proven for periodontitis or cavities specifically |
| Limit frequent sugar exposure | Ongoing | Frequency of exposure matters as much as total amount |
| Routine check-up and clean | Every 6–12 months | Catches most problems while still cheap and painless to fix |
The one habit worth prioritising
Brush for the full two minutes with fluoride toothpaste, twice a day. It's the single habit with the strongest, most consistent evidence in this entire guide, and it's the one most people underdo without realising it.
