During the periodic check your dentist looks at your teeth from all sides. Your dentist can see if there is likely to occur cariers in your teeth or if previously cariers has become bigger of has been repaired with a filling. If that is the case, then it may be necessary to make an x-ray. In case of crowns and bridges your dentist looks if the edges fit snugly and if there are no leaks. If during the inspection it is clear that something needs to be repaired, we will make a new appointment for you.
