Very curious as I was doing some toothpaste shopping. I’ve recently started having sensitive teeth and would like to know if it works and how. Thank you
In: Biology
If you live in countries outside the USA, you can buy toothpaste that contains a type of bio-glass that will fill in the holes in your teeth. Originally designed to repair shattered bones of soldiers, it was adopted for use in toothpaste. Once the holes are filled in, cold/hot liquids cannot pass into your tooth and irritate the nerve inside.
I have no idea why you cannot buy these toothpastes in the USA. You can order them online from Canadian resellers. Theories range from FDA blocking it’s use in toothpaste to a conspiracy by the Dental Association.
