What percentage of hydroxyapatite does this toothpaste have?
What is the exact percentage of hydroxyapatite? I ask because to be as effective as fluoride at preventing cavities it should be minimum 10%.
Flouride free or not? As I scrolled on I read "active ingredient flouride"
Is there artificial sweetner in this? Sure i saw saccharin in the ingredients

amazing at cleaning
I use this in combination with a regular fluoride toothpaste (biomed before regular) because I’m prone to cavities, It does such a good job at soothing my gums and sensitive teeth while gently removing all of the plaque and tartar build up over time. it has a mild mint taste and isn’t sensory overwhelming. my teeth feel so smooth after using and i’ve seen a noticeable reduction in sensitivity, gum recession and cavity development

The best toothpaste
Best toothpaste I have ever used! My teeth were demineralising and were looking yellow and sensitive with white spots from too much fluoride . Within a week of using the calcimax toothpaste along with their herbal mouthwash , my gums stopped bleeding, my teeth got whiter (because enamel got stronger) and I feel confident about my smile again.I use a bit to put on my teeth before bed as well after brushing and don’t rinse and I think keeping it overnight is also what helped.Definitely recommendUse hydroxyapatite instead of fluoride , it’s so much better for you!

Brilliant toothpaste
I always used regenerate for the longest time and maybe there was an improvement but that wasn't on an upward trajectory.it flatlined...so I thought I would try this,so the taste is palatable and I see a slight improvement again so I think I can alternate between them and be happy. This is cheaper than regenerate and has the same positive effects

I found it no better than normal tooth paste to be honest
It does make your teeth feel nice though

Absolute improvement in dental health
I've been doing a lot of research into negative affects of sodium Fluoride as a tooth cleaner after my dentist prescribed a high dose fluoride toothpaste which was awful. I binned it after 2 uses. I've since learnt that modern toothpastes and also their chemical ingredients are the root cause of many issues. So why do dentists promote sodium Fluoride toothpaste? money in their pockets I guess!After a painstaking search for a toothpaste that doesn't have all these nasties, I found this one.Already, after only a couple weeks I've noticed a huge difference!My teeth are whitening and feel more secure in my gums. My gums are healthier and my breath is fresher.I was expecting a not so nice flavour based on some reviews but it's quite nice I'd say, it has a mintyness.Yes it's 5x more expensive than a regular tube of toothpaste but it'll save me tons in the dentist chair no doubt.I'll be subscribing!

Seems to work!
I've just ordered three more tubes as a follow-up to the original single.A bit of information first: toothpastes for 'sensitive' teeth seem to contain one of three main ingredients. Either stannous chloride, potassium nitrate or calcium hydroxyapatite.Ones with calcium hydroxyapatite are very hard to find and tend to be very expensive on a tube-by-tube basis.Scientific research shows that the ingredient works effectively to remineralise enamel.I tend not to brush my teeth with Biomed in the conventional manner.My dentist recommended sluicing my mouth out with water after eating acidic foods and then smearing a pea-size pellet of the toothpaste directly on to the area of sensitivity.Tooth enamel softens after eating (acidic) foods and naturally remineralises/hardens in about thirty minutes.The idea is to keep the toothpaste in your mouth for as long as you can before spitting the surplus fluid into the basin.Smearing clearly concentrates the product in the area most likely to benefit.Took about three days for the treatment to work for me. Tooth no longer temperature sensitive. I just follow the 'rinse and smear' routine everytime I eat something. Relatively hassle-free.A single tube lasts for ages. For me it seems to work. Your mileage may vary but at a very reasonable £4.00 or so a tube, worth a try to find out!I would have preferred a 'fresher'/'more minty'/'punchy' flavour but it might just be that such additions reduce the effectiveness of the remineralisation process. Certainly not unpleasant, just a bit bland. Anything but a deal breaker.Hope helpful.
