The ancients said, "If the lips are gone, the teeth will be cold." This refers to the fact that the front incisors are not called "ya" (molars). The Shuowen Jiezi states: "Qu is the decay of teeth by insects." It means teeth hurt due to decay. Those pains not caused by decay are likely due to wind-cold invading the brain marrow. The Suwen states that severe cold reaches the bone marrow; thus, there is headache and also toothache. One should treat it according to this principle.
