Gap in Crowns
The only way for you to develop a gap like that is that your teeth have shifted. The only way for you to close the gap is to move the teeth back to where they were. (of course, you can make new crowns, but that's overkill ) It's possible that your bite has caused the teeth to shift so that may need to be addressed. You can also have an orthodontic appliance made to close the space and then you would need a retainer to hold the teeth in place. I don't think just making a new nightguard will suffice. If you have further questions, let me know.
