There is no problem with toothpaste being eaten in the stomach. The toothpaste itself is an antiseptic, and it has a certain role in cleaning and promoting the oral cavity. After eating into the stomach, the toothpaste itself has no obvious damage to the gastric mucosa, but has a certain bactericidal effect on the mucosa of the gastrointestinal tract. Of course, toothpaste is not used clinically as an antiseptic solution, because the composition of toothpaste itself is not conducive to the absorption of the gastrointestinal tract mucosa. Therefore, a small amount of toothpaste or inadvertent ingestion of toothpaste, which has no other damage to the gastrointestinal mucosa, should not be too worrying. Clinically, for other gastrointestinal problems, such as gastric ulcer or GERD, there may be upper abdominal discomfort, and most of these symptoms can be relieved in 1-2 hours with the absorption of toothpaste.
