There is no difference in toothpastes. There is not a single reliable evidence of this. Short-term contact of the paste with the mucous membrane does not cause almost any effects and does not lead to metabolism. For mineralization of enamel with paste components, it must be in the mouth for days. What matters is the brushing technique and the choice of toothbrush.
Toothpaste is a consumer product, not a medicine, so most toothpastes do not undergo appropriate clinical trials. Any manufacturer can buy any toothpaste formula, name it beautifully and advertise it as you like.
Therefore, dentists have developed a unified recommendation for toothpastes: The toothpaste must be changed regularly (every two to three months). You also need a regular visit to the dentist, who, by the way, will immediately indicate the poor effectiveness of the toothpaste and brush, if this takes place.
From my own experience, I can add that toothpaste in the "above average" price segment is really more effective, and the manufacturer does not really matter if you adhere to the basic rule of regular replacement of the toothpaste. I don't know any miracle super toothpastes.
There is a difference. There is a paste with whitening properties, with herbs, with and without fluoride, with and without calcium, and so on. By the way, I recently moved to another city, the water here contains a lot of fluoride, so I use a fluoride-free paste so that my teeth do not deteriorate from an overabundance of the above element. Therefore, you need to choose the paste for yourself. And it is advisable to know what kind of water in the water supply (chlorination, fluorinated, etc.), depending on this, choose a paste. It is also advisable to consult with your dentist, he will tell you which paste is best for you.
