Many people experience nausea while brushing their teeth in the morning, and some even vomit. Why does this happen? The reasons are as follows:
1. Some individuals squeeze too much toothpaste onto their brush. Excessive toothpaste creates abundant foam during friction in the mouth, which can irritate the throat and trigger nausea.
2. Many people brush their teeth with cold water year-round, regardless of the season.However, cold water is detrimental to dental health. On one hand, cold water fails to soften toothbrush bristles in colder weather, potentially causing gum bleeding during brushing and triggering nausea. On the other hand, brushing with cold water (especially in winter) creates a significant temperature contrast with the mouth, which can stimulate oral nerves and induce nausea.
3. Some individuals suffer from chronic pharyngitis or gastric disorders.
Proper Brushing Techniques
1. Apply an appropriate amount of toothpaste—typically one-third for brushes with denser bristles and one-half for those with sparser bristles. This prevents waste and avoids discomfort during brushing. Consider using a children's toothbrush.
2. During spring, fall, and winter (especially winter), use lukewarm water between 30°C and 40°C (adjust to personal comfort). First, soak the toothbrush in the water until the bristles soften, then apply an appropriate amount of toothpaste before brushing. This prevents gum bleeding and avoids nausea when rinsing with warm water.
3. When brushing, exhale through your nostrils instead of breathing out through your mouth.
4. For those with chronic pharyngitis, in addition to following the above brushing methods, take medication promptly and minimize or avoid smoking.
Method One: Drink plenty of warm water daily, ensure adequate sleep without staying up late, eat light meals, avoid fried, grilled, spicy, or irritating foods, and consume more fresh fruits and vegetables. Focus on vitamin-rich fruits like kiwi and figs. Watermelon, known for clearing heat, soothing the throat, and quenching thirst, is an excellent choice among fruits.
Method 2: Persistently rinse your mouth with diluted salt water morning and night. Tilt your head back while rinsing, open your mouth wide, and utter an "ah" sound. After rinsing, consider drinking a cup of diluted salt water. This primarily sterilizes, cleanses, and moisturizes the throat, improving its environment and preventing bacterial infections. With consistent practice over six months to a year, chronic pharyngitis symptoms may disappear clinically.
Method Three: Regularly rinse with compound borax solution, furazolidone solution, or 2% boric acid solution. Tilt your head back slightly while gargling and open your mouth to make an "ah-ah-ah" sound, allowing the solution to clean the posterior pharyngeal wall. You may also frequently dissolve throat lozenges.
Method Four: If pharyngeal mucosa shows congestion and thickening, with submucosal connective tissue hyperplasia and enlarged mucous glands producing excessive secretions, consider laser therapy. For severe cases, laser treatment should be administered in multiple sessions. Alternatives include silver nitrate application, cryotherapy, or iontophoresis. Nebulization therapy or throat sprays may also be effective.
Friendly Reminder: If you experience nausea or gagging while brushing your teeth, try the above methods. If they prove ineffective, consult a doctor, as the issue may stem from gastrointestinal disorders.
