Sounds odd, but possible. Pothole damage rarely gets both sides, but it could have been some other type of road defect. That kind of jolt is something you wouldn't forget, though. Remember any incidents? It would be enough to rattle your teeth.
Usually you can try to make a claim against the appropriate municipality for damage/repairs if it is something on the road/street/highway that should have been fixed (particularly if it had been reported to the appropriate organization). They budget quite a bit for this type of compensation.
