Crown sensitivity when pressing on tooth

[Annino1219]

Hi everyone. In late September I got a root canal and crown placed on my upper rear molar. The root canal was done by an Endodontist and the quality was checked by another Endo. Both docs signed off on it.

The crown lately feels strange when I press on the tooth from the biting surface. Almost like a sensitive type feeling when I press. No temperature sensitivity fyi.

Any idea what this could be from?

Could be that the occlusion needs to be adjusted. If the occlusion is slightly off, it could lead to periodontal ligament widening and also pain.
