Teeth become very painful after alcohol?

So like us all I like to go out for a drink on weekends but the problem I have is after having a few drinks my teeth become extremely painful and impossible to eat for a couple of days after!

My teeth are always fine, never normally have any problems but it only happens after alcohol. For example I went out Saturday night and had a few to drink and since then, I cant eat at all because its too painful! I try everything, I brush all the time, brush again before I go out to drink etc but Why is this? And is there anyway I can stop it!!
