What to do with thick tongue coating

The tongue coating is very thick. You need to go to the stomatology department of the hospital in time. If it is caused by poor oral hygiene, you need to pay attention to oral hygiene, rinse your mouth and brush your teeth in time. If it has nothing to do with oral problems, it is considered to be caused by indigestion. You need to go to the gastroenterology department of the hospital in time. After diagnosis, you should follow the doctor's advice and use drugs to promote gastric motility.
