Sensodyne Novamin vs. Regenerate

teamwork

Does anyone know if there is a difference between "Regenerate Enamel Science" toothpaste and "Sensodyne Repair and Protect" containing Novamin?

From a close inspection, the active ingredients in Regenerate, NR-5, consists of "The NR-5™ is a unique and internationally patented technology present only in REGENERATE Enamel Science™.
NR-5™ is based on two minerals called Calcium Silicate and Sodium Phosphate that combine to form fresh Hydroxyapatite - the core enamel mineral."(https://www.regeneratenr5.co.uk/pages/faq).

Looking at the ingredients list of the Sensodyne toothpaste, it states "Calcium Sodium Phosphosilicate (NOVAMIN), "

Now correct me if I'm wrong, but it seems that Calcium Sodium Phosphosilicate is a combination of the same 2 ingredients in the Regenerate toothpaste. If so, is there any reason to buy Regenerate when the Sensodyne version is so much cheaper? Sensodyne is £3 for a 75ml tube in Sainsbury's and Asda. I can even get 60 sample sizes on eBay for £9.99 giving me 900ml.

Regenerate, on the other hand, is a minimum £10 per 75ml tube.

Furthermore, I have found this website where they claim that they make a toothpaste containing Biomin which they say is better than Novamin, so this is even more confusing:

The point with almost all of these toothpastes is they only (in theory) rebuild enamel on a microscopic level. In other words if you can see the damage the toothpaste will make no difference at all .

For most people any toothpaste with fluoride in it will do just a good a job as any other.

The exceptions are

Sensitive toothpastes which are effective in treating sensitive teeth

High fluoride toothpastes which are suitable for certain people and are available on prescription only

Biomin which actually has some good science behind it but it is best asking your dentist if it is necessary for you.
