First question is are you of Swedish descent? 1 in 700 swedes have Amelogenesis imperfecta. 1 in 14000 Americans.
Amelogenesis imperfecta is a tooth development disorder in which the teeth are covered with thin, abnormally formed enamel.
The enamel of the tooth is soft and thin. The teeth appear yellow and are easily damaged. Acidic foods like oranges, tomatoes, and pineapple dissolve the enamel. Also soda, which has phosphoric acid. Both baby teeth and permanent teeth are affected. The enamel is easily fractured and damaged, which affects the appearance of the teeth, especially if left untreated.
The treatment depends on the severity of the problem. Sealants are a good preventative measure. White dental varnish is another layer of protection for the tooth and helps restore natural color. Both the front and the back of teeth are affected. Full crowns will improve the appearance of the teeth and protect them from damage.
Amelogenesis imperfecta is passed down through families as a dominant trait. That means you only need to get the abnormal gene from one parent in order for you to get the disease.
My experience has been dentists don't diagnose this and thus proper treatment is delayed. Good luck. Hope this helps.
