Tooth is more painful now its been filled than before. Is that normal?

Its normal for a really big filling to be sensitive for the first couple of weeks. Your dentist was just drilling on your tooth so that can make it sensitive too. However if it feels like your filling is high or your hitting it first or harder then the rest of your teeth you should go in and have it adjusted. Also if you don't like how the top one feels you can have the dentist smooth it out or wait because it may smooth out with normal chewing.
