Introduction

In general, the formation of a tooth-marked tongue is associated with excessive dampness in the body. Both cold-dampness and damp-heat can lead to excessive internal dampness; therefore, the presence of tooth marks may indicate either cold-dampness or damp-heat. If discomfort occurs, it is recommended to seek timely consultation and treatment at a qualified hospital. Once a tooth-marked tongue appears, a professional TCM practitioner should first perform pattern differentiation to distinguish between the cold-dampness and damp-heat types.

Generally, the formation of tooth marks on the tongue is associated with excessive internal dampness, and both cold-dampness and damp-heat can lead to excessive dampness in the body. Therefore, the presence of tooth marks may indicate either cold-dampness or damp-heat. If discomfort symptoms occur, it is recommended to seek timely diagnosis and treatment at a qualified hospital. Detailed analysis is as follows:

If the body contains excessive cold-dampness, it can easily weaken the spleen and stomach's transformation and transportation functions, impairing the normal elimination of dampness and causing accumulation of dampness in the body. This dampness may浸润 the tongue, making it swollen and enlarged. Due to the limited space in the mouth, long-term contact between the enlarged tongue and the edges of the teeth results in tooth marks. This type of tooth-marked tongue typically presents with a pale tongue color and a thick white coating on the tongue. Symptoms such as cold intolerance, cold limbs, loose and unformed stools, and fatigue may also appear, indicating an overall cold condition of the body.

If internal damp-heat is present, the pathogenic factor of damp-heat can obstruct the flow of qi in the spleen and stomach, affecting dampness metabolism and leading to dampness retention in the body. This retained dampness similarly causes the tongue to swell and enlarge, resulting in tooth marks due to pressure from the teeth. This type of tooth-marked tongue often presents with a red tongue color and a yellow, greasy tongue coating. Common accompanying symptoms include dry mouth, bitter taste, sore throat, sticky and unsatisfactory bowel movements, dark yellow urine, and skin pimples, indicating a condition of intermingled dampness and heat in the body.

Once tooth marks appear on the tongue, a professional TCM practitioner should first perform pattern identification to distinguish between cold-dampness and damp-heat types; self-treatment without proper diagnosis is not recommended. In daily life, avoid prolonged exposure to damp environments and reduce consumption of raw, cold, sweet, greasy, and spicy foods to prevent exacerbation of internal dampness.
