Floss will not fit between new crown. Will this go away with time?

You should definitely be able to floss between the crown and adjacent teeth.  If not, call and have your dentist take a look.  There may be a piece of cement that needs to be removed.  It should not be difficult to correct.  

This is something we see often.  You should definitely be able to floss between the crown and adjacent teeth. If not, call and have your dentist take a look. There may be a piece of cement that needs to be removed. It should not be difficult to correct and should only take a few minutes.

There are two reasons this is happening.  Either there is excess cement between the crown and the adjacent tooth, or the contact is very tight.  Both have an easy solution.  You will need to go back to your dentist and have them see what the issue is.  Your dentist will either remove the excess cement or loosen the contact.

Time typically will not improve the ease of flossing in a new crown. There can be left over cement that was used to place your crown left in between your teeth. Or the area may be slightly tight to floss. Either situation will require you to visit your dentist for him to properly check the situation and eliminate the tightness for you.All the best.

After cementing a crown it is routine to floss between the teeth to remove excess cement stuck between.  If there is cement between the teeth and if fully sets it is very difficult to remove.  I would suggest you see your dentist with the concern and see if they can get floss through the area.  It could also be an extremely tight contact between the teeth that is preventing your flossing as well.
