 Hello Q and A with Dr. Jay here. We had a question last week about how we deal with spacing stainless steel crowns and issues where we have space loss. So here you can see in the lower quadrant here, focusing up on tooth number L, we have resolution and we could have some potential movement of the second primary an alarm to the face. And that can make some challenges for restoring this too. So one option would be to reduce the mesial surface of the tooth that's moved forward discurts the primary tooth. A better option is probably to try to contour your crown and you can do this by getting contouring pliers and taking them in the opposite direction you would do to crimp the crown. This can play a little indent into the crown and alleviate some of that space where the tooth has moved in so you don't have to touch it and be able to have a good fit for that stainless steel crown. So hope that helps you and
