Tongue scraping is dangerous because it may damage the tongue; it is not therapeutic, but it can clean the tongue.
Patients who scrape their tongue too hard may scratch their tongue. If the tongue is scraped too often, it may cause the tongue to become infected, which is harmful. In addition, tongue scraping has no therapeutic effect, but when the tongue is too thick, proper scraping can clean the tongue from food residues.
Patients are advised to scrape their tongue less often in their daily lives, as tongue coating is generally normal and does not require excessive cleaning. If the patient’s tongue is too thick, then the tongue can be scraped appropriately. Patients should pay attention to their diet and clean their mouth in time. If uncomfortable symptoms occur, they should consult a doctor in time.
