If you’re buying hydroxyapatite toothpaste for the first time, you do not need a row of tubes. You need one paste you can actually find in the UK, the brush you already use, and two ordinary weeks to see how it feels.
That small set is the starter kit. It sits beside the fluoride toothpaste the NHS still centres. It does not take its place.
What the NHS still says about brushing
The routine is already settled. Brush twice a day, including last thing at night. Use a fluoride toothpaste. Spit, and don’t rinse straight away.
NHS teeth-cleaning advice says adults should use a paste with at least 1,350 ppm fluoride. On a family tube in a UK bathroom, that is usually printed as 1,350–1,500 ppm. A soft or medium brush is enough. About two minutes.
A hydroxyapatite tube does not change those steps. If a dentist has already chosen a fluoride paste for you, stay with it unless they change it. Trying a mineral paste is a shopping choice. It is not an upgrade on that advice.
What to put in a first kit
Keep it on one shelf.
One hydroxyapatite toothpaste. The toothbrush you already like. A glass by the sink, so you can spit without washing the paste straight off. A fortnight is long enough to learn the taste. It is not a course of treatment.
You do not need a second brush, a whitening extra, or three flavours before you know whether this suits you. Many of these pastes foam less than a supermarket mint. A brush that looks almost dry is normal.
This kit is for an adult. Toothpaste for children, and what to think about in pregnancy, is on the kids and pregnancy guide.
Which tube to try first
You are in Boots, turning a carton over. Or you are on Amazon, looking at a Japanese import. Either way, buy one tube.
Biorepair is the hydroxyapatite paste UK chemists have carried. The brand says the powder is micro, not nano, and calls it microRepair. Look it up with a Boots search for Biorepair. Check the page on the day, and read which variant is in your hand.
Apagard Premio is a Japanese paste. The brand says it uses nano-hydroxyapatite. In the UK it is usually an import, so the seller and the tube size matter as much as the name. Any percentage on a listing is the brand’s figure. We have not measured the powder. If the carton does not print a number, do not invent one.
Pick one for the first fortnight. Micro and nano are different labels, not a score. They are explained in the nano vs micro guide. Boka, RiseWell, Truthpaste, and Gem can wait. Those names are on the Biorepair vs Boka vs Apagard page.
In 2025 a European consumer-safety committee looked at nano-hydroxyapatite in toothpaste. Where the particles matched the shape in that opinion, it considered amounts up to 29.5%. That is a note about a cosmetic formula. It does not mean your tube contains that much, and it is not a reason to choose nano over micro.
How to use it for two weeks
Brush the way you already brush. Morning, and last thing at night. A pea is enough. Spit. Don’t rinse straight away.
The NHS gives that spit instruction so a fluoride paste is not washed off at once. Do the same with a hydroxyapatite tube. You are not learning a new method.
Give it two weeks before you decide. That is long enough to notice the taste, how little it foams, and whether your mouth feels comfortable. It is not a promise about how your teeth will look.
If the paste feels gritty, or the mint is too sharp, stop, or try the other style of tube. Do not brush harder to make up for the quiet foam.
Read the carton once, before the first night. It should say hydroxyapatite, not only a nickname. Then see whether fluoride is listed, and at what ppm. Plenty of these pastes are fluoride-free. That is a choice some adults make after reading hydroxyapatite vs fluoride toothpaste. It is not an instruction to drop a paste your dentist has already chosen.
What you might notice
After brushing, teeth can look a little smoother in the mirror. That is a cosmetic change. It is not a treatment for decay, and it does not rebuild a tooth.
Some packs talk about a cleaner, brighter look. Read that as surface appearance. It is not a bleach treatment, and there is no shade we can promise.
If nothing feels different after two weeks, that can be a normal result. You can go back to the fluoride tube you started with.
When to see a dentist
Leave the basket if something hurts.
See a dentist for pain, a hole you can see, swelling, gums that keep bleeding, or sensitivity you cannot explain. A new tube will not sort those.

What to read next
The mineral, in plain English, is in what hydroxyapatite toothpaste is. If cold drinks are the reason you are changing paste, that is a different question: hydroxyapatite for sensitive teeth. More explainers are on the guides index. How the shopping links on this site work is on our disclosure.
