A. I am unsure of the cost of dental treatment in India, but I would advise that you shop around first. Don’t necessarily go for the cheapest options. You get what you pay for, and I would definatley advise a good quality cosmetic dentist to carry out the work.
Composite fillings on the front teeth is an option- as long as you are aware that they can stain slightly over time and may need replacing in the future.
Veneers are also a good option for closing the teeth. You do not necessarily need 6 veneers. It is hard for me to comment, as I haven’t seen you myself.
Expect to pay around £700 per veneer at a good practice.
Some dentists can treat you very quickly, but I prefer to take time in planning the smile design first and making sure that you are happy with the planning before treatment commences.
Hope this helps.
