Hi..best and permanent solution is ceramic laminates or zirconia crowns. These are permanent and never change shade. Regards

hello sir...   Discolouration is due to so any reasons...    **plaque and calculus    **smoking and pan stains..    **coffee and tea stains    **natural colour of the dentine(imside tooth structure)    **Flurosis... For normal deposits and stains you need to go for scaling(Teeth cleaning) and polishing..it starts from rs..800. For  mild flurosis  you will go for teeth whitening procedure... Clinical examination is necessary to rule our what kind of treatment you need for your yellowish teeth.... scaling is a simple non surgical procedure ...it wont create any gaps between your teeth.. It is mandatory to do scaling for every 6 months

you can go either for bleaching or composite veneering  , both are non invasive procedures. bleaching may cost u upto 10k and composite veneering upto 1000 to 2000 rs per tooth

This is almost the 4th time you asking the same question. I said earlier a round of scaling will help. It will cost you from 800 to 2000 INR It is not an operation No gaps will as such appear in between your teeth
