In a Dedekind domain the powers of a prime ideal are contained only in other powers

I'm currentley working on Dedekind domains and the following statement seems true to me but I don't know how to prove it.
If $Pneq 0$ is a prime ideal in a Dedekind domain, then if $ P^nsubseteq I$ with $I$ an ideal we have $I=P^m $ for some $mleq n $.
Is this true? If it is, how do I prove it?

Are you allowed to use that non-zero ideals in Dedekind domains admit a unique factorization into maximal ideals?

I tried induction and using the fact that every prime ideal is maximal. And yes, I'm allowed to use the prime factorization. I was wondering if I can say something like if a product of primes is contained in a product of primes then each prime in the first product is contained in a prime in the second, or something like that.
