[|Human|] I have a 9 almost 10 month old and Ive noticed his top teeth (the half towards the bottom) are yellow and Rough and not smooth like the white part is. Ive tried brushing, changed the water I used in his bottle, what can i do to fix this, I dont want him walking around with yellow teeth/ rotten teeth til he loses his baby teeth
[|AI|]  Hellooo....1st of all I would like to ask u whether u had taken any medicines for diseases in pregnancy???if taken tetracycline etc. then it can cause staining...next thing is that whether your staying in an area where there is a lot of fluoride in your community water supply??then also it can stain....and can cause roughness....if it cannot be brushed off.then its from inside the tooth...nothing to worry....can do procedures like bleaching and all.but It's actually not needed in this milk teeth...in my opinion I will say let this tooth be yellow and take care for permanent tooth....hope u have got reply....had a nice day!!!
