These spots and discolouration of teeth happens when the fluoride
content in the water that you consume is above the desired value at the time of teeth development. You can opt for teeth bleaching
if the stains are superficial.
If not you may have opt for caping (full coverage) Veneering (partial coverage) of your teeth. It is better that you do not opt for any treatment in the milk teeth as they will shed off. And wait for the permanent teeth to erupt completely and then opt for caping or veneers
. If you desire for proper esthetic and are concerned even now for the discolouration then you can choose to opt for direct veneers rather than Indirect veneers. Direct veneers - they are filling Agents placed directly on your teeth to cover the discolouration. When the teeth erupts fully they can then be extended further. Indirect veneers - these are like partial caps which are fabricated from lab and are pasted over the teeth .if you opt for these you will have to get them replaced once the teeth erupt completely. please visit your doc and get the rite treatment for your child.
