I am Ann, mum to a twelve year old son.

Recently I have noticed that a few of the front teethes of my son have become yellowish. He himself brushes his teethes from a very young age of around 3 (first few months I helped him). He brushes twice a day in the morning and night. He is not having any pain or complaints.

What are the reasons for this? Is it due to excessive intake of Calcium or any other food? Do I need to consult a dentist?

Please advice.
