How to use hydroxyapatite toothpaste.

You use hydroxyapatite toothpaste the same way as any toothpaste: brush twice a day for two minutes, then spit. The ADA recommends a rice-grain smear for children under 3 and a pea-sized amount for ages 3 to 6. Adults commonly use a pea-sized amount.

A few habits come up more often with hydroxyapatite. Many people spit without rinsing so the paste stays on their teeth longer, and SLS-free formulas like One+ foam less than regular toothpaste, which is normal. If you also use fluoride, you can combine the two in one routine.

The routine 2 minutes, twice a day Then spit. Children under 6 use ADA amounts.

01

Two minutes, twice a day

That's the ADA's general brushing advice, and it applies to hydroxyapatite toothpaste too.

02

Spit, don't swallow

Klyyr's instruction is to spit after brushing. Supervise children so they spit rather than swallow.

03

Low foam is expected

One+ uses sodium cocoyl glutamate instead of SLS, so it foams less. Foam isn't a measure of cleaning.

Before you start

Switching from fluoride?

Ask your dentist first if you have high cavity risk or use a prescribed fluoride product. You don't have to choose one or the other.

Brushing with braces?

Use the same routine, with extra attention around brackets and wires.

Using an electric toothbrush?

You can use hydroxyapatite toothpaste with an electric toothbrush. A low-foam paste is less messy on a powered brush.

In short

Right amount, two minutes, spit. The rest is doing it every day.

01 Should I rinse after using hydroxyapatite toothpaste?

It's a personal choice. Many people spit and skip rinsing so the paste stays on their teeth longer. See should you rinse after brushing.

02 Can I use hydroxyapatite toothpaste every day?

Yes. It's made as a daily toothpaste. Brush twice a day and spit.

03 Should I use hydroxyapatite toothpaste at night?

Brush both morning and night. Some people use a hydroxyapatite paste at one brushing and a fluoride paste at the other, if their dentist recommends fluoride.

04 How much hydroxyapatite toothpaste should I use?

Adults commonly use a pea-sized amount. For children, the ADA recommends a rice-grain smear under age 3 and a pea-sized amount for ages 3 to 6. See how much toothpaste to use.

05 Why doesn't my hydroxyapatite toothpaste foam?

Many hydroxyapatite pastes, including One+, skip sodium lauryl sulfate, the ingredient that makes regular toothpaste foam. Less foam is normal and doesn't mean it cleans less.
