Chris- Jeff is right, and if you have a digi cam, snap a couple of pics and post them so we can see. If you don't have one, I know not everyone does, answer these questions so we can help you better.
1. Are they on the snakes underbelly (ventral side) which is white on most BPs, or are they on the snakes top (dorsal side) which is the part that is colored and has the markings.
2. What is your experience level? Are you new to snake keeping and how long have you had your BP?
3. Describe what you are calling "dead scales," why do you say they are dead? Some BPS do have white patches of scales, sometimes called ringers, which occur naturally. It also could be several layers of stuck on shed. We need a detailed description of what you are seeing.
4. What are your temps, and your humidity level?
If you can answer these questions, or even some of them, please do and we may be able to help you better.
And if pics are possible, that is the best way
