I went to the dentist 3 months a go they took a x ray and everything was fine. So I went to the dentist again yesterday and my dentist said that I have resorption on my tooth number 30, wich she said already have a root canal and crown. She told me that I need to remove that tooth. Please is that anything I can do to save my tooth? How could that even be possible ? In 3 months from one x ray to another to lead into lose my tooth?
