How long does a tube of toothpaste last? For one person using a pea-sized amount twice a day, a 60g tube lasts roughly four months. Squeeze a full strip along the brush every time and it's closer to a month. Share that tube between a family of four and it might last anywhere from a week to a month, depending on how much everyone uses.
The honest answer depends on three things: how much paste goes on each brush, how many people share the tube and how well you get the last bit out. Below we do the maths, show how many tubes a typical household needs each year and share simple ways to spend less without cutting corners on your teeth.
How long does a tube of toothpaste last for one person?
Toothpaste amounts are hard to measure at the sink, so we've used rough, commonly quoted estimates: a thin smear weighs around a tenth of a gram, a pea-sized amount about a quarter of a gram, and a full strip along an adult brush head around a gram. These are ballpark figures rather than measurements, but they show how much the amount matters.
Here's how long one 60g tube lasts one person brushing twice a day:
| Amount per brush | Rough weight | Used per day | One 60g tube lasts |
|---|---|---|---|
| A smear | About 0.1g | 0.2g | About 10 months |
| Pea-sized | About 0.25g | 0.5g | About 4 months |
| Half strip | About 0.5g | 1g | About 2 months |
| Full strip | About 1g | 2g | About 1 month |
The gap between a pea-sized blob and a full advert-style strip is roughly four times as many tubes a year, for the same two minutes of brushing.
What changes the answer
Your own tube might run out faster or slower than the table suggests. The main factors are:
- How much you squeeze. This makes the biggest difference by far.
- How many people share it. Two people using the same amount halve the life of the tube.
- Extra brushing. Brushing after lunch as well as morning and night uses more.
- Tube size. Tubes come in different sizes, and some are labelled in grams and others in millilitres, so compare like with like. All Nice Smile tubes are 60g.
- Waste. Paste left in the crimped end, dropped blobs and dried-out nozzles all add up.
How many tubes does a family get through in a year?
Scale the numbers up to a whole household and the differences get bigger. Assuming everyone brushes twice a day:
| Household | What they use | One 60g tube lasts | Tubes a year |
|---|---|---|---|
| One adult | Pea-sized amount | About 4 months | About 3 |
| One adult | Full strip | About a month | About 12 |
| Couple | Half strip each | About a month | About 12 |
| Family of four | Everyone pea-sized | About a month | About 12 |
| Family of four | Two adults half strip, two children aged 3 to 6 pea-sized | About 3 weeks | About 18 |
| Family of four | Everyone uses a full strip | About a week | Nearly 50 |
For the NHS guidance on children's amounts (a smear for under-3s and a pea-sized amount for children aged 3 to 6), see our guide to how much toothpaste kids should use.
Why the right amount matters more than saving paste
Using the right amount isn't only about money. For young children, the NHS recommends specific amounts because swallowing too much fluoride while adult teeth are forming can cause faint white marks on the teeth (dental fluorosis). So stick to a smear or a pea-sized amount, depending on age, and supervise brushing until around age 7 or 8.
For adults, NHS guidance focuses on fluoride strength: a toothpaste containing 1,350 to 1,500ppm fluoride. Many dental professionals say a pea-sized amount is enough for adults too, so ask your dentist what's right for you. Whatever you use:
- brush twice a day for about two minutes, last thing at night and at one other time
- spit out the excess, but don't rinse, so fluoride keeps working
- replace your toothbrush every three months
Seven ways to make a tube go further
- Measure with your eyes. Aim for a pea-sized blob, not a brush-length stripe.
- Squeeze from the bottom. Roll or fold the tube up from the crimped end as you go.
- Store it cap-down. Standing the tube on its cap keeps paste near the nozzle, so less effort, less waste.
- Keep the cap on. A dried-out nozzle wastes paste every time you clear it.
- Give children their own tube. A flavour they love, and a tube that's theirs, can mean less fuss at bedtime.
- Note the date you open it. Write it on the tube and you'll soon know your household's real rate.
- Buy by the tube, not by the trip. Bigger packs usually cost less per tube, as long as you'll use them all before the date.
What does toothpaste cost your household each year?
Once you know roughly how many tubes you get through, the price per tube is what really matters. Here's what 12 tubes a year (roughly what a couple, or a family of four all using a pea-sized amount, might get through) would cost with different Nice Smile packs, using prices from when we checked in September 2026. Amazon prices can change, so check the current price before you buy.
| How you buy 12 tubes | Price per tube | Cost for the year |
|---|---|---|
| 12 single tubes (Watermelon Fresh) | £7.95 | £95.40 |
| 4 × 3 Pack (Berry Burst, Yummy Gummy & Candy Clean) | £5.56 | £66.76 |
| 4 × 3 Pack (Watermelon, Grape & Peach) | £4.33 | £51.96 |
| 2 × 6 Pack (All Flavours) | £3.66 | £43.98 |
| 1 × 12 Pack Toothpaste Bundle | £2.08 | £24.95 |
Price per tube is a quick way to compare packs that all use the same 60g tube. When sizes differ, compare the price per 100g instead; our guide to reading unit prices shows you how.
The Nice Smile 12 Pack Toothpaste Bundle contains four tubes each of Watermelon Fresh, Feelin' Grape and Peachy Clean. The listing describes it as a whitening fluoride toothpaste for kids and adults that's vegan, cruelty-free and enamel-safe.
One honest caveat: if you live alone and use a pea-sized amount, 12 tubes could be several years' supply, which may take you past the date printed on the tubes. Smaller packs suit smaller households better. Our guide to whether toothpaste expires explains how to check.
A sweeter option for younger brushers
If your children are fussy about flavour, it can be worth letting them try something sweeter before committing to a big bundle.
The Nice Smile 3 Pack in Berry Burst, Yummy Gummy and Candy Clean contains three 60g tubes of flavoured whitening fluoride toothpaste, described on the listing as vegan, cruelty-free and enamel-safe, for kids and adults. It was £16.69 when we checked in September 2026. Check the pack for the fluoride level before choosing it for a young child. You'll find every pack size in our bundles collection.
The bottom line
A 60g tube of toothpaste lasts one person about four months with a pea-sized amount, or around a month with a full strip. For a family of four, expect anything from a week to a month per tube. Use the right amount for each age, squeeze from the bottom, note the date you open each tube and buy in a pack size you'll finish before the date. At PoundMart, we bundle toothpaste so you pay less per tube and run out less often.
Frequently asked questions
How long does a tube of toothpaste last for one person?
Using a pea-sized amount twice a day, a 60g tube lasts one person roughly four months. With a full strip along the brush each time, it's closer to a month. Writing the date on the tube when you open it is the easiest way to find your own figure.
How many tubes of toothpaste does a family of four use in a year?
It depends on how much each person uses. If everyone uses a pea-sized amount twice a day, a family of four might get through about 12 tubes of 60g a year. If everyone squeezes a full strip, it could be nearly 50.
How much toothpaste should an adult use?
NHS guidance for adults focuses on fluoride strength: a toothpaste with 1,350 to 1,500ppm fluoride. Many dental professionals say a pea-sized amount is enough for adults too. Ask your dentist if you're unsure what's right for you.
Is it cheaper to buy toothpaste in bulk?
Usually, yes. When we checked Nice Smile prices in September 2026, a single tube of Watermelon Fresh cost £7.95, while tubes in the 12 Pack worked out at £2.08 each. Bulk buying only saves money if you use every tube before its date, so match the pack size to your household.
Should each person in the family have their own tube?
It's not essential, but separate tubes can help, especially with children who prefer different flavours. It also lets you keep an eye on how much each person is using. Whatever you do, keep caps on and avoid pressing toothbrushes against the nozzle.
