I was having mangoes (with seed) 2-3 days back and suddenly I felt a sensation on my front tooth which had undergone root canal with procelain crown 3 years back. I felt the crown coming down but on close examination it started shaking. I went to the doctor for an xray... the xray was normal but he was not sure on the tooth beneath the crown. he is suspecting a fracture but is not sure. He has asked me to wait and watch for the crown to fall off on its own. If he tries to take the crown out ..it may actually fracture the tooth. The tooth is not that wobbly and it has been close to 6 days now. Please advise...i don't want to get an implant if it is avoidable..there is no bleeding or pain.
