Dear Lybrate user,
if your tooth is yellow colour since childhood, it my be your natural colour. If you are not clean your teeth by dentist
in near minimum six month, then please consult to dentist for scailling or bleaching
of your teeth. After scailling/bleaching you will obtain your natural colour teeth. *i want to remind you again that scailling of teeth in less than 6 month is harmful of teeth. Minimum time period between two scailing should be 6 month.
