#asktheexperts Sir, my child has stains in his teeth. He is 7 years old now. He brushes his teeths regularly 2 times a day but then too there is no reduction in the stains. When he was 3-4 years old we used to give him a little amount of tea. But we have stopped it since a long time. He gets tea only on once or twice a month now. Kindly suggest some remedies.
