Phenergan should not cause you to have dry mouth or dry socket. However, SMOKING can cause dry socket and this can be pretty bad after having a tooth pulled. If you are a smoker, don't smoke until at least 72 hours after having a tooth pulled.
You should also avoid sucking through a straw, spitting forcefully and carbonated beverages.
Let me know if you have more questions.
