DS1 is 7 and has only lost two teeth so far (his two bottom teeth at the front). The adult ones are almost fully through. I noticed today that they are really quite yellow. Is it normal for adult teeth to be more yellow than baby teeth or is this something I should be concerned about? He has never had any dental problems and brushes his teeth twice a day. Recently I think we've become more lax about sugar between meals - could this be a cause?
He has just finished a course of antibiotics - could this have had an effect?
TIA
