Dentists of mumbai

So,I have seen videos of famous international dentists online saying teeth whitening can be done effectively at home using hydrogen peroxide whitening strips and it might sometimes give at dental office like results,I tried looking for similar products in india like crest whitestrips and opalescence go whitestrips but there are basically almost no whitestrips with hydrogen peroxide in India,I wonder what dentists of india or particularly mumbai have to say about this and what is like there go to product for in office like whitening results for the hollywood smile.would appreciate any normal persons personal teeth whitening product experiences too.
