The wavy shape of the edge of the tongue is mainly a sign of tooth compression, also known as the tooth-scarred tongue, which is caused by the swelling of the tongue after squeezing the surrounding teeth and the shape caused by tooth compression, in a jagged or wavy shape. Clinically, the appearance of this tongue is mainly considered to be a large amount of dampness in the patient’s body, mainly caused by a weak spleen qi or qi deficiency, which can be treated with medications, such as Ginseng and Atractylodis Macrocephalae, Mu Xiang Shun Qi Wan, and Tonic Zhong Yi Qi Tang, which need to be applied reasonably under the guidance of a doctor. Add foods to your diet to dispel dampness, such as barley porridge and mung bean porridge. Usually eat less fatty foods that are particularly fatty, meat should be eaten in moderation, and proper physical exercise can help to dispel dampness and strengthen the spleen, which can eliminate the marks around the edge of the tongue.
