Floss every night
After brushing, before bed. Floss between every tooth, every night. The most-skipped basic in adult dental health.
Run a 30-day cycle with floss every night.
The Cycle Planner walks you through six steps and gives you a clean plan to start from. We'll prefill the habit, the suggested length, and a starter exit condition.
Plan a cycle with this habit
The dentist asks every six months. Most adults nod and lie. Daily flossing is the basic dental habit that even otherwise organised people skip, because it sits in a five-minute window where the mind has already clocked off for the day.
The whole habit is one rule: floss after brushing, every night. Same trigger, same place, same time. Stack it onto the brushing habit that’s already running and you’ve removed most of the friction.
What it looks like
Brush as normal. Before putting the toothbrush down, take a length of floss. Floss between every tooth, top and bottom. Spit, rinse, done.
Keep the floss in the holder next to the brush, not in a drawer. Visibility is the cue. A drawer is where habits go to die.
Why it works
Brushing reaches about 60% of tooth surfaces. The remaining 40% is where most decay starts and where periodontal disease begins. Thirty days of flossing won’t undo a decade of skipping it. It will halt the progression, and gums look noticeably healthier in the mirror by the end of the cycle.
The other effect is the stack. Once flossing becomes part of brushing, it loses its independent status as a habit you have to remember. It becomes a step in an existing routine, which is the cheapest form of installation in the library.
Common pitfalls
The first pitfall is buying expensive floss picks and using them inconsistently. Boring string floss at the cheap end of the chemist works fine. Use what you have, every night.
The second is moving the habit to the morning. Mornings are too rushed for a skill that takes a minute, and night flossing prevents the overnight bacterial bloom that does most of the damage.
The third is missing one night and writing off the cycle. Miss it, floss the next morning, continue. The bigger failure mode is binary thinking, not the missed night.
A 30-day cycle suggestion
Thirty days, every night. Success criteria: 28 out of 30 nights flossed before bed. The habit either installs cleanly in a month or it doesn’t, and the mirror gives feedback either way.
Exit condition: when flossing happens after brushing without being decided. Most people who run this cycle don’t need a second one. The habit graduates into infrastructure.
