Is Hydroxyapatite Toothpaste Safe? Every Question, Answered

Hydroxyapatite toothpaste has grown quickly in the UK and most of the questions we get are variations on the same theme: is it actually safe? Short answer: yes, for the reasons below.

Is hydroxyapatite safe to swallow?

Hydroxyapatite is the same calcium phosphate mineral that makes up around 97% of tooth enamel and much of bone. In the small amounts present in toothpaste, it isn't a safety concern if swallowed accidentally. As with any toothpaste, it's meant to be spat out, not eaten.

Is it safe for children?

Yes. Hydroxyapatite itself is non-toxic and suitable for children. ApaCare toothpaste also contains fluoride at 1450ppm, appropriate for children 6 and under, use only a pea-sized amount and supervise brushing to avoid swallowing, in line with NHS guidance on children's toothbrushing. If your child is already taking additional fluoride, check with your dentist first.

Does hydroxyapatite replace fluoride?

No, they work differently and are best used together; see our full hydroxyapatite vs fluoride guide. ApaCare toothpaste contains both hydroxyapatite and fluoride so you don't have to choose.

Is there microplastic in hydroxyapatite toothpaste?

Not in ApaCare's, our toothpaste is formulated without microplastics or titanium dioxide. Always check the ingredients list of any hydroxyapatite toothpaste, since this varies by brand. More on ingredients worth checking in our toothpaste ingredients guide.

Is hydroxyapatite toothpaste abrasive?

ApaCare's is formulated to a low RDA (relative dentin abrasivity) value of 40, well within the range considered safe for daily use, so it cleans without excessive abrasion.

How do I know it's working?

Look for teeth that feel smoother and look glossier with regular use. Remineralisation is a gradual, ongoing process rather than an overnight change, so results build with consistent twice-daily brushing rather than on a fixed timeline.

FAQs

Can adults and children use the same hydroxyapatite toothpaste?

Yes, ApaCare's Toothpaste is suitable for the whole family, with a pea-sized amount and supervision for children 6 and under.

Does hydroxyapatite toothpaste have side effects?

It's generally very well tolerated, since it's the same mineral as natural enamel. As with any toothpaste, stop use and speak to your dentist or doctor if you notice irritation.

Is hydroxyapatite toothpaste better than fluoride toothpaste?

They're complementary rather than competing, see our full hydroxyapatite vs fluoride guide.
