Can Swallowing Mouthwash Make You Sick
What Happens When Mouthwash Goes Down: Most mouthwashes contain ingredients that can upset your stomach if swallowed in significant amounts. The alcohol content in many brands ranges from 15% to 27%, which is stronger than beer or wine. When this enters your stomach, it can irritate the lining and cause nausea, vomiting, or general discomfort. Even alcohol-free versions contain chemicals like fluoride, chlorhexidine, and essential oils that were designed for your mouth, not your digestive system.
