I have got problem with my teeths. I brush them everyday but still there colour is "Yello". They used to be white before 5 years but now they are all yellow. I am 18 now and very upset about them. Does anyone know how to make them white again? Please!!!
You can try brushing them with pure baking soda. Thats what my mom always told me to do.
Plus, theres plenty of toothpastes out on the market that has baking soda and peroxide in it.
Further to the previous answers, a chat with your dentist will ensure that your colour change is due simply to food discolouration, or maybe natrual aging, and not sign of something that needs attention.
I have been told by dentists that if you had certain antibiotics as a child (tetra - something) then the yellowing is irreversible. Sorry! It is still worth trying the suggestions.
