The reason vantej toothpaste (dr. Reddys labs) is prescribed is usually for hypersensitivity.
It contains calcium sodium phosphosilicate to help repair dentin and teeth hypersensitivity.
No issues as such if you use it daily only factor is price that 100gms of vantej costs more compared to 100gms of colgate /pepsodent/etc or any other widely used toothpaste brands. Also more than the toothpaste brand, brushing regularly and using the right brushing technique is very important. And that will help more than toothpaste selection
hope this answers your query.
