[|AI|]  Hello there... Root fracture occurs for various reasons. It depends on the root morphology and the way it is removed.... The dental surgeon has to remove the tootChatDoctorpletely. A maxillary molar (upper molar) usually has three roots. Morphology at times can be different.  There are situations where in you can retain the fractured roots. It is a fact that any root piece measuring less than 4 mm (few consider it 2-3 mm) can be retained as it gets resorted. Molar teeth are usually close to the maxillary sinus. Improper attempt to remove the root stump would displace it into the sinus resulting in unnecessary complications. So for the benefit of the patient we inform them and leave the root stump for resorption. It resources most of the time or it stays dormant. Any root fragment measuring more than 4 mm should not be retained as it would lead to complications in the future in terms of cyst or interfere with healing or with your replaced teeth.
