First, the enamel is damaged and sensitive to cold, hot, sweet and sour. The first harm and influence of too long brushing time is the damage to the enamel on the tooth surface. Enamel is wrapped around the surface of our teeth, just like a protective paint, which can be said to be the first line of defense for our teeth. If you brush your teeth for too long, the constant friction between toothpaste and toothbrush will damage and thin the enamel, and eventually lose this protective coating, and the subsequent effect is that dentin allergy is easy to decay.
Second, fragile gums are prone to bleeding. Our periodontal tissue and gums are very fragile parts. If we brush our teeth for too long, it will cause irritation and damage to the skin of periodontal gums, and even lead to bleeding and inflammation. Therefore, when brushing your teeth, treat your gums gently, and don't let them rub for a long time. You must know that your gums are healthy and your teeth will be great.
Third, the oral mucosa is easily damaged. Toothpaste is an edible preparation, but many of its ingredients will cause irritation to oral mucosa. It is acceptable for us to brush our teeth and rinse our mouths for a short time. If we brush our teeth for too long, our tongue, maxilla and other mucous membranes will feel more or less uncomfortable, which will easily cause burning sensation and damage to oral mucosa in the long run.
This is the effect of brushing your teeth for too long, so when is the best time to brush your teeth? Generally speaking, about 3 minutes is appropriate. If it is too short, it will not clean, and if it is too long, it will be too easy to walk too far, so friends must grasp the time.
