At the moment one of my top back Wisdom tooth/teeth are sensative after my front Molar was scrapped and filled in order for a crown to be put in next week. Is it possible for the other tooth or teeth to feel sensative even if they are three or four teeth apart? if so why does that happen, because nerves are connected or something or should only the tooth/teeth right next to the one being worked on feel sensative & not the one few teeth apart. Thanks.
