Why do you brush your teeth every day? How to avoid dentin hypersensitivity caused by tooth washing?

Washing teeth can clean bacteria in the mouth, but brushing teeth can't remove many bacteria. Regular tooth washing is still very good for teeth, so why do you need to wash your teeth every day? How to avoid dentin hypersensitivity caused by tooth washing?

Why do you brush your teeth every day? Some people think that if you brush your teeth carefully every day, you don't have to wash your teeth, which is wrong. Due to the rapid formation of plaque, new plaque will be formed within half an hour after thorough cleaning, and the maximum amount can be reached within 30 days. What's more, most people have not mastered the correct method of brushing their teeth. They just clean their teeth according to their own habits. It is inevitable that some parts are not brushed in place, especially between the teeth and the lower incisors, which will become calculus over time. Therefore, if adults have not washed their teeth, they should go to the hospital for tooth cleaning as soon as possible, preferably once every six months.

How to avoid dentin hypersensitivity caused by tooth washing 1? For patients with many and thick dental calculus, poor anti-inflammatory effect of drugs or poor desensitization treatment, experts suggest that it is too hard for these patients to wash their teeth once, but they are easy to accept. Moreover, anti-inflammatory treatment or desensitization treatment can be continued during tooth cleaning, which can greatly relieve pain.

2. Over the years, regular tooth washing has accumulated a lot of hard dental calculus, so it is necessary to increase the strength of dentifrice to remove dental calculus, which will aggravate toothache. Therefore, according to the formation of dental calculus and gingivitis, experts believe that regular tooth washing for half a year, one year or two will not cause pain when dental calculus is small and loose, which is easy to remove.

3. Desensitization treatment before tooth washing leads to "ache and weakness" mainly due to dentin allergy. According to clinical observation, most people are sensitive to hot, cold, sweet and sour stimuli in their daily lives among people who have severe pain and weakness when washing their teeth. 4 ~ 10 days before tooth cleaning, it is suggested to use toothpaste with desensitization function to desensitize teeth, which can reduce the sour and soft feeling during tooth cleaning. It can still be used after tooth washing to reduce the pain after tooth washing.

Toothache? When washing teeth, dentin allergy will make you feel sore. This is because dental calculus can easily grow in difficult-to-clean positions, and these positions are the parts of dentin allergy! When cleaning teeth, it will make a harsh sound, which is actually a normal sound made by the ultrasonic tooth cleaner at work, and it will hardly hurt teeth.

Why does tooth washing bleed? There will be some bleeding, but it's normal. If there are a lot of calculus or gingivitis, bleeding is normal. The gingival margin is not closely attached to the tooth surface, but there is a shallow groove with a depth of 0.5-2 mm, which is called gingival sulcus.
