Q. After having pain in one of my upper front teeth, I was advised to have two root canals redone. I was still in pain after this treatment and was referred to a periodontist who after examining me proclaimed that I have a bone fracture above my front teeth and a large cyst. I have been advised to have the following treatment: removal of my 4 front teeth 7,8,9 & 10 bone grafting implants on teeth 7 & 10 bridges on teeth 8 & 9 Firstly what would cause a bone fracture? Does this treatment sound like a good option? I am a little wary especially after the initial misdiagnosis, the periodontist did ask why the root canals had been re done and then suggested that maybe the fracture had been missed on previous x-rays (4 were taken before treatment began, and 2 after), is this a likely scenario? The periodontist noticed the fracture on my full mouth x-rays and then confirmed it with 2 more. Apologies if I have muddled my questions somewhat, I am still in shock!
