My son is studying in seventh grade. Last day while climbing a tree, he fell on the ground and he broke a large portion of his front tooth. Also, his gums became swollen and I made him apply cold packs to it. But it cures pain only for a while. He refuses to eat or drink anything when the pain befalls. When I discussed this with my aunt, she suggested visiting a dental clinic at Toronto for emergency dental treatment. Also, when I googled, I found that crowning is a solution for his broken tooth and the dentist might take x-rays to check the root of the surrounding bone. Are dental x-ray’s safe? What type of crowning metals are available? How long do dental crowns last? Please share your views!
