Question pt, ask if they feel numb?
Probe the palate or gingivae
Check the percussion of the tooth with the handle.

If the object is closer to the X-ray source it will move in the opposite direction to the X-ray. An example of this is a buccally placed canine.
If the object is further away from the X-ray source it will move in the same direction. For example a palatally placed canine.
