I am 54 and over the last two and half years have lose three stone on a diet. Three months ago I was diagnosed with a underactive thryoid and am now on 50mg levothyroxine. At the same time as being diagnosed I started having major dental work four implants and then last week one of my bridges fell out. Most people are saying they put on weight but so far I haven't. I am now worried that the reason I haven't is because of my teeth as I cannot eat easily . I do not feel any different and in fact feel very depressed. ( but this could be due to my teeth) any help or advice would be greatly appreciated.
