My 5 year old has just seen the dentist and been diagnosed with this I’ve been waiting for it to be honest as my husbands family all have it. Any advice on what we should be doing the dentist said to go to the GP which I’ve made an appointment for but any other advice. I like our dentist but she’s been quite laid back about our concerns and now an adult tooth has come through she seemed quite alarmed and didn’t have a lot of information except wait and see which I think is wrong. I’m going to get a second opinion also. Any help would be great, I know it’s rare but we are fortunate in a way to know it’s definitely this because of the long family history however so much has changed since my husbands diagnosis 30 years ago. All her baby teeth are very small and yellow her brothers are perfect and white.
