Running out of toothpaste on a school morning is nobody's idea of fun. Here's how long a tube really lasts, how to plan for a whole family, and how to make sure you never run out.
How long does a 100g tube last?
With twice-daily brushing, one 100g tube of Flossy & Pure lasts one person about 4–6 weeks on average. How much paste goes on the brush makes the biggest difference.
How much toothpaste should you use?
- Under 3: a smear.
- 3–6 years: a pea-sized amount.
Supervise children until they can spit reliably. There's more on age-by-age brushing in Can Kids Use Adult Toothpaste?
Planning for a family
When a family shares one tube, it goes faster. The more people brushing from it, the sooner you'll need the next one. Little ones using a smear go through far less than adults.
That's why many families keep one tube in each bathroom. The Family 3-Pack gives you three 100g tubes, which is about 3–4 months for one person, or one tube for every bathroom. It works out at $19.67 a tube.

Never run out: Subscribe & Save
If you'd rather not think about it at all, Subscribe & Save sends your toothpaste on a schedule you choose: every 4, 8, 12 or 16 weeks, with 15% off. Skip or cancel anytime. It's available on the single tube and the Family 3-Pack. Pick "Subscription" on the product page.
As a rough guide based on 4–6 weeks per tube for one person, a single adult on single tubes might start with every 4 or 8 weeks, and a family might match the 3-Pack to how quickly your bathrooms empty. You can see how your first delivery goes and adjust from there.
How to tell your toothpaste is still good
Every Flossy & Pure tube has its batch and best-before date printed on the base. Once opened, it's best used within 12 months.
