Vomiting, also known as emesis, is the involuntary expulsion of stomach contents through the mouth. It can be caused by a variety of factors, including illness, motion sickness, and certain medical conditions. While vomiting is often a harmless occurrence, it can also be a sign of a more serious underlying medical condition, such as a gastrointestinal disorder or food poisoning.
Dentists are trained to look for signs of vomiting during routine dental exams. This is because vomiting can damage the teeth and gums. Stomach acid can erode tooth enamel, and the force of vomiting can cause the teeth to become loose. In addition, vomiting can lead to dehydration, which can also damage the teeth and gums.
