Analysis:

We advocate brushing your teeth in the morning and evening and gargling after meals. Brushing your teeth before going to bed is the most important, because saliva secretion will be reduced after falling asleep, and saliva can wash away bacteria and inhibit bacterial reproduction. If you don't brush your teeth before going to bed and don't clean it, food residues will ferment and produce acid under the action of bacteria. In addition, due to the lack of saliva in sleep, the oral cavity can not dilute and neutralize the acid produced by bacteria, so the teeth will be easily corroded, which may lead to dental caries for a long time. So brush your teeth before going to bed, clean up the food residue left between your teeth and your teeth, and don't eat anything after brushing your teeth, so that you can maintain oral hygiene overnight.

Brush your teeth effectively: choose a soft-haired healthy toothbrush; Put the toothbrush bristles at the junction of teeth and gums, with the bristles pointing in the direction of root and making an angle of 45o with the tooth surface, vibrate horizontally in situ, and then brush vertically along the teeth. You can also draw a circle on the tooth surface; Brush all parts of the teeth in a certain order; Brush your teeth sooner or later; Brush your teeth for 3 minutes at a time.

Some people brush their teeth like a saw, that is, they brush them sideways. This method of brushing teeth is harmful. Over time, the root of the tooth will be "sawed" into a deep groove, which is called "wedge defect" in medicine. People with this wedge-shaped defect will have toothache if they eat cold, hot, sour and sweet food. In severe cases, it will also cause pulpitis and make your teeth fidgety.

Sticking to the correct brushing method can remove dental plaque and gum. Healthy people usually brush their teeth 1 ~ 2 times a day, but people with gum or periodontal disease should emphasize brushing their teeth in the morning and evening, and brush their teeth for 3 minutes every time after lunch. The correct brush method is short horizontal brush and vertical rotating brush.

Short transverse brush method (also known as transverse vibration method): People are used to a long saw action. If a hard toothbrush is added to this horizontal brushing method, it will cause damage to periodontal tissue (bristles will damage gingival margin, gingival recession, wedge-shaped defects in root and neck, etc.). ). short transverse brush method short vibration transverse brush action can clean dental plaque best, so it is also called in-groove brush method. Brush Mao Mao's nose and teeth? The gingival surface is slightly pressurized at an angle of 45, and the top part of the bristles enters the gingival sulcus, and the other part is outside the gingival sulcus, and then vibrates back and forth for 6 ~ 8 times. When it vibrates, the bristles only move 1 mm. When brushing the lingual surface and palatal surface of the upper and lower front teeth, if the dental arch is narrow, the toothbrush head can be erected for short-term horizontal brushing vibration. At the same time, the occlusal surface of the posterior teeth should be brushed and the pit and fissure of the occlusal surface should be cleaned.

Vertical rotation method: it can effectively remove dental plaque and soft dirt, and can keratinize gums and maintain the normal shape of gums. The choice of toothbrush is very wide, both hard toothbrush and medium hard toothbrush are acceptable, but the elderly, children or patients with periodontal disease should choose medium hard or soft bristle toothbrush after operation. The action of brushing the buccal and lingual surfaces of the back teeth is to make the bristles parallel to the long axis of the teeth and stick to the tooth surface, with the bristles pointing to the gingival margin, twist the toothbrush under pressure to make the bristles form a 45-degree angle with the long axis, and rotate the toothbrush, that is, brush the bristles down between the teeth when brushing the upper teeth, and brush them down when brushing the lower teeth. Be careful to move slowly, with a little tremor, and repeat the same part for 5 ~ 6 times. Brush the lingual and palatal surfaces of the front teeth with the same rotation as above. If the dental arch is narrow, the toothbrush can be pressed vertically, and a part of the hair bundle is pressed on the gum, which is brushed to the crown along the interdental space, and at the same time, the occlusal surface of the posterior teeth is brushed.

Toothpaste contains abrasives and detergents, which can prevent caries, diminish inflammation, stop bleeding, prevent acid, relieve pain, inhibit tartar and relieve bad breath, so using toothpaste when brushing teeth can enhance the effect of cleaning teeth.

Brushing your teeth can effectively control bad breath.

Bad breath is an embarrassing thing for yourself and the people around you. What's more, many people have bad breath, but often don't know it. In fact, the method of self-examination is also very simple. You can cover your nose and mouth with your hand, exhale and inhale through your nose, so that you can smell the smell in your mouth. Director of the Department of Stomatology of Shanghai Renai Hospital pointed out that the key to bad breath is not only bad smell, but also some potential diseases.

(1) The diseases that cause bad breath are:

There are many kinds of microorganisms in the cavity of dental caries, mainly Streptococcus mutans and Lactobacillus, which can cause germs and emit a bad smell.

The main pathogens of gingivitis and periodontitis are Porphyromonas gingivalis, Fusobacterium, other anaerobic bacteria and microaerobic bacteria. These bacteria themselves emit a special smell, and the smell in the mouth is mostly caused by this bacteria.

Wenjie's gingivitis is mainly caused by the smell of gum tissue necrosis caused by Fusobacterium.

Oral ulcer mucosal tissue necrosis, gum necrosis.

Leukemia gingivitis gum necrosis.

(2) Mucins in saliva ferment in the mouth and give off peculiar smell.

(3) Poor oral hygiene maintenance, such as tartar, tartar and dental plaque on the tooth surface. Food scraps between teeth and smoking lead to bad breath.

(4) Gastrointestinal diseases such as gastritis and duodenal ulcer can cause halitosis.

(5) Odors from nasal diseases such as sinusitis are emitted through the mouth.

(6) Lung diseases give off bad smell through the mouth.

If you have bad breath, you should first rule out whether the digestive system and respiratory system are sick, and then further check the oral diseases. Some anaerobic bacteria and micro-aerobic bacteria in the oral cavity can cause diseases, but there are also non-pathogenic bacteria, some of which belong to pigment bacteroides, and all of them will produce odor.

It is very important to prevent bad breath and maintain oral hygiene. You should brush your teeth twice a day. Especially before going to bed at night, you should brush it carefully. Brushing teeth can reduce oral microorganisms by about 60%. If you don't brush your teeth, just gargling can only reduce 65,438+05%, which shows the importance of brushing your teeth.

Rinsing your mouth carefully can eliminate the residual smell of food. Put water in your mouth, squeeze water with your tongue, rinse your cheeks, and rinse several times to remove odor. If there is still food smell, put some green tea in your mouth and rinse your mouth. Chlorophyll in tea can remove odor.

The treatment of halitosis is based on the cause. If bad breath is caused by tartar, tartar and dental plaque on the tooth surface, you should go to the stomatology department to remove the dirt on the tooth surface and clean the teeth (such as ultrasonic cleaning). In addition, it is best to clean it twice a year. In addition; Some bad breath is caused by dental caries and periodontal disease. Because periodontitis is inflammation and suppuration of periodontal tissue, alveolar bone is absorbed, periodontal pocket is formed between teeth and gums, and bacteria multiply in periodontal pocket. Generally, brushing your teeth and gargling have no therapeutic effect, so you need to go to the stomatology department for treatment. The water laser system equipment imported from Shanghai Renai Hospital can treat the hard and soft tissues of oral cavity, with a wide range of treatment. Most operations can be painless and painless without anesthesia, so that patients who come to see a doctor can be treated. Water laser technology has become a model of painless dental treatment with its humanized design concept and multiple functions.
