I took my son (6) to the dentist the other day and she pointed out that a couple of his back teeth were showing signs of hypomineralisation (white spots on the teeth). I didn't really think much of it at the time, but now I've googled it, I see that it can be quite a serious problem and lead to browning then crumbling teeth etc.
Anyone had this and got any advice? I don't know whether to brush his teeth more or less or if there's anything else I could do.
