Is it possible for teeth to decay inside out?

In brief: No

Decay starts on the outside and travels inside.
However, the penetration may be small and then the destruction occurs like cutting the inside out of a pumpkin. It will seem like it is from inside -> out. Also, you can have internal resorption from inside. This is not decay, per se, but the result is the same.

It can seem like it when the tooth can be cavernous, but it definitely starts on the outside.
