Deficiency fire toothache refers to a poor physical condition with swollen and painful gums as the main manifestation. The main manifestations of deficiency fire toothache are red and swollen gums, inability to chew food, inability to touch the teeth, and enlargement of the jaw lymph nodes. There are also usually changes in other parts of the body, such as a thick yellow tongue, bitter mouth, fever, and constipation. Patients often attribute this to fire. The specific local cause in the mouth is often very clear, mainly due to the growth of bacteria in the mouth, plaque and calculus deposits. The most immediate treatment is to go to a regular hospital dental clinic for scaling treatment, gum rinsing and medication on the obvious swollen areas, removing local irritants, and gently and carefully removing plaque and food debris with a soft-bristled toothbrush. Patients with symptoms such as thick yellow tongue, bitter and dry mouth can seek Chinese herbal medicine to regulate the balance of body yin and yang and strengthen body immunity. In daily life, it is important to pay attention to a light diet, avoid spicy and stimulating foods, adjust work and rest, regulate negative emotions such as tension and anxiety, exercise appropriately to increase the body’s metabolic activity, and correct endogenous abnormal factors.
