First, lingual papillitis
There are many papillae on the tip of human tongue. We call this tiny papillary substance a filiform nipple. If there is infection, the filamentous nipple will become inflamed. When the filiform nipple is inflamed, tiny erythema will appear on the human tongue, which will cause the patient's tongue to be red and accompanied by tongue pain, which will affect the patient's daily diet. In view of this phenomenon, we must go to the hospital for corresponding drug treatment, and patients should pay attention to controlling diet and maintaining personal hygiene.
Second, tip friction.
People's tongues are very sensitive and fragile. Many people like to lick their teeth with their tongues, which is very hard. In the process of licking teeth with the tongue, the friction between the tongue and the teeth will in turn lead to the patient's tongue redness, which is not harmful to the patient's health, so we don't need to worry too much, just get rid of this bad habit.
Red tongue is generally caused by two factors, one is disease, and the other is bad living habits. If the patient has no discomfort except red tongue, it is mostly caused by bad living habits, which is not harmful to the patient, so you don't need to worry too much. But if the patient's tongue is not only red, but also accompanied by tongue pain and redness, it is best to go to the hospital for examination. This situation is generally caused by inflammation, and if left untreated, it will bring more harm to patients.
