Teeth "Li Du" (progressive dental caries and decay) refers to the phenomenon where teeth are corroded and gradually disintegrate. This is primarily due to deficiency of Kidney Qi, leading to instability of the bone marrow, and depletion of Qi and Blood, which fails to nourish and fill the oral cavity and teeth. Consequently, the teeth appear dark black, a condition termed "Li Du".
