TEETH
The second-best alternative to saving yourself from being infected with the zombie virus (the first being the destruction of the brain, for those who haven’t been paying attention) is to take out the blighter’s teeth. If a zombie has no teeth then you can’t get bitten.
The handy thing about teeth is that they are situated quite near to the brain, so if you do miss the brain you could possibly take out the teeth instead (or the nose – but that’s not very handy as the zombie virus is not passed on through touching a zombie’s nose). Either way, repeated blows to anywhere around the facial area should do something that will aid in neutralising the zombie threat so stick with the original plan of going for the head.
NOTE: The virus will not be passed through the teeth. It will be passed from the saliva in the mouth. Removing the teeth will merely cause an open wound through which the virus may pass into your bloodstream. If a toothless zombie was to bring its mouth into contact with an open wound on your body you would still be infected.
