Medicines will not help. You need scaling and bleaching for your problem

Ur dental health is more important Dan the colour of ur teeth so first get ur dental check up done n ur dentist will update u n solve ur problem

Go for scaling and bleaching also

Medicines cannot work too whiten teeth,so get scaling and bleaching done from a dentist.

yellowish shade of teeth is common feature of indian population. what type of yellowishness you have we have to see first either it is due to fluorosis or normal shade . there are options like vennering either composite or ceramic depends on your preference of choice . but normal scaling will not improve those yellow shade if its due to calculus( dirt) on ur teeth means it will definitely goes while during scaling. thank you

U get a bleaching done
