The cause of a cracked filling may occur for many reasons, such as chewing too hard, grinding your teeth, clenching teeth together, or secondary cavity that forms under the filling . Take an X-ray to check if there is any cavity that has formed . if you do nothing, it may get worse. You could end up getting an infection in the tooth, which could turn into an abscessed tooth if left unattended. So visit a dentist near by and start the treatment . Take care
