Vantej Toothpaste

Yes you can use toothpaste apfter bleach. And if your teeth is yellow then you can go with snowhite tooth paste.

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.

there is some error in understanding the purpose and effect of the tooth paste. your black stains will go by proper brushing with any toothpaste or by professional cleaning but if the black color area is cavity then no toothpaste will fill it and make it white.

My personal opinion goes with Pepsodent germicheck. For hair we should not use shampoo daily two to three times a week is good use ketoconazole shampoo.

Get a scaling procedure done for removing superficial stains from your teeth. You can also undergo a teeth bleaching procedure.
