4 weeks post permanent crown and my jaws are constantly tight, do I need an adjustment?

Last week I went to my dentist to address the tightness in my jaws. I told him that my bite feels low and I can only feel my left back teeth touch (where I had crown placed) when I clench hard. Dentist did a ink bite test and showed me that all my teeth were touching and made me feel as if I was wasting his time with my concern. I’m having headaches and it hurts my jaws to put my teeth together. Everything feels off and my jaws are constantly tight. He said I just need to give it time to adjust.
