###Human: A bit of molar tooth fell out from my mouth while taking food. What can I do now? ###Assistant: Hi. It can be a fractured crown of the tooth due to a cavity. You should get an X-ray done to know whether it needs root canal treatment or it needs a simple filling. Please send a picture of it to guide you further and to make a diagnosis. It is better to get it filled as soon as possible. Do not be afraid of dentists.
