Misalignment often bites the tongue repeatedly, beware of tongue cancer! Miss Li, 28, often bites her tongue because of her irregular dentition, which leads to repeated injuries and ulcers. Because I didn't follow the doctor's advice to correct the dentition, the tongue injury has not healed for a long time, and it has actually deteriorated into tongue cancer when I went to the hospital for examination. Tongue cancer is primary on the mucosal surface, and more than 90% is squamous cell carcinoma, which can produce ulcers, irregular white spots or orange peel-like protrusions, which is related to the eating habits of patients such as chewing betel nut, smoking, drinking alcohol or eating spicy food. Miss Li's diet is normal, and she doesn't smoke or drink, which may be because her dentition is uneven. Long-term stimulation may cause repeated damage to her tongue, leading to cancer. Those with irregular dentition, sharp teeth on the lingual side caused by grinding teeth, tongue hypertrophy or abnormal tongue nerve function caused by stroke are the main groups who bite their tongues, and most of them have irregular dentition, which not only affects their appearance, but also affects their health. If you often accidentally bite your tongue or mouth, you'd better go to the hospital for examination and correct it in time. If oral and tongue wounds last for two weeks, or irregular white spots and orange peel-like protrusions appear in the wounds, it is best to go to the doctor for examination in time to avoid delaying the illness. Bite your tongue often, beware of lacunar cerebral infarction! The health care guide says that it is common to bite your tongue when you are old because you eat or talk carelessly. However, if the old man often bites his tongue inadvertently, he must be extra careful, because he may be suffering from a disease called lacunar cerebral infarction. Medical experts have found that lacunar cerebral infarction is a special cerebral infarction with high incidence, which mostly occurs in the elderly with hypertension, hyperlipidemia and diabetes, and the number of patients accounts for nearly 20% of the total number of patients with cerebral infarction. At the initial stage of lacunar cerebral infarction, the symptoms are not obvious, such as poor speech, a little salivation in the mouth, slow swallowing when eating, frequent tongue biting and so on. This is because the local microvascular infarction in the brain, brain tissue ischemia and necrosis, so that the tongue loses elasticity. In addition, poor fine movements, such as dropping chopsticks when eating, are also one of its manifestations. Therefore, if the elderly find themselves frequently biting their tongues recently, or accompanied by dizziness, headache, unsteady walking, unclear speech and other symptoms. They should seek medical care and receive formal examination. Otherwise, missing the best treatment opportunity will lead to the recurrence and aggravation of the disease, and then there will be typical symptoms such as unfavorable limb movement, poor language, mouth and eye deviation, which will not only be difficult to treat, but also leave sequelae for most patients.
