are you still eating all kinds of sweets without restraint? Do you still eat sugary food, processed fine food and yogurt? You have to pay attention! Relevant expert research shows that oral health and whether teeth are clean are closely related to our daily diet. The color and spots on the surface of teeth are directly affected by diet. Most people’s concept of dental health care is to maintain correct brushing habits and have regular examinations, but do you know? More efforts should also be made on food to protect teeth. Food plays a key role in tooth health. Therefore, in daily

, the internal environment of the oral cavity affects the probability of tooth decay.

the oral cavity is the external environment of teeth, which is closely related to the occurrence of tooth decay, in which food and saliva play a leading role.

food: in daily eating habits, the main impact on tooth health is the carbohydrates contained in food. Bacteria can use carbohydrate metabolism to produce acids and synthesize extracellular polysaccharides and intracellular polysaccharides; The organic acid produced is conducive to the demineralization of tooth hard tissue. Polysaccharide can promote the adhesion and accumulation of bacteria on the tooth surface and provide energy source, resulting in tooth decay.

saliva: Although saliva has the functions of cleaning, inhibiting bacteria, anti acid and anti dissolution under normal conditions. However, changes in the amount and quality of saliva can affect the probability of tooth decay. Patients with xerostomia and saliva secretion have a higher probability of tooth decay. The increase of lactic acid in saliva is also conducive to the occurrence of tooth decay.

What are the causes of tooth decay?

any product containing fermentable carbohydrates (sugar and some starch) may cause tooth decay. In addition, the formation of dental caries is also affected by many different factors.

there are four main factors leading to tooth decay. Only when these four conditions are met can tooth decay be caused.

1, susceptible host, i.e. weak teeth

2, pathogenic bacteria

3, suitable substrate, i.e. acid producing food

4, long enough action time, i.e. pathogenic bacteria and acid producing food act on teeth for a long time, resulting in demineralization of dentin and enamel, and finally dental caries.

health care misunderstanding prone to occur in the process of tooth protection

myth 1: the more times you brush your teeth every day, the less your teeth will rot.

the health status of teeth and oral tissue is not directly proportional to the number of tooth brushing. Pay attention to timing when brushing your teeth: after dinner and before going to bed; Master the method, vertical brush, inclined 45 degree pressure brush method; Choose fluoride toothpaste and brush each face of each tooth carefully; Use dental floss to remove food residues between adjacent teeth and control the accumulation of dental plaque on the tooth surface. The above comprehensive measures can maintain the health of tooth hard tissue and soft tissue (gums, etc.). The way of brushing your teeth, which only talks about the number of times and the improper method, can not really protect the health of your teeth.

Myth 2: if your mouth has a peculiar smell, just use the mouthwash sold in the mall.

bad smell in the mouth (also known as bad breath) may be caused by poor oral hygiene, resulting in calculus deposition, and the decomposition of anaerobic bacteria in the mouth to produce putrefaction and necrosis smell (sulfide bacteria, indole, etc.). The formed calculus cannot be removed by brushing or gargling. The fundamental method is to go to a specialized hospital for periodontal scaling or curettage, and completely remove calculus, so as to improve the condition of halitosis.

misunderstanding 3: after tooth cleaning, there will be calculus, and tooth cleaning is useless at all.

dental calculus is like hair. It is constantly formed and accumulated in one’s life unless you want to & quot; Long hair & quot;, Otherwise, you should clean regularly (half a year and a l year) instead of once and for all.

myth 4: there are 28-32 teeth, and it doesn’t matter if there are a few.

the teeth in the oral cavity are interdependent, restrict and coordinate with each other. The loss of each tooth (except wisdom teeth) will lead to the inclination of adjacent teeth to the missing tooth area and the elongation of occlusal teeth to the missing tooth area, resulting in the masticatory function disorder of the whole oral and maxillofacial system. This is a slow and undetectable process, and once it occurs, it is often difficult to remedy. Therefore, we should take good care of our teeth as we do to protect our eyes. For missing teeth, we should set teeth in time (after three months).

myth 5: what is the use of prevention? Only see a doctor when you are sick. Why go to the hospital when you are not sick?

the role of prevention is to nip in the bud. This is the primary prevention of oral diseases, including caries, periodontal disease, dental deformity and oral cancer. The specific measures are systemic and local application of fluoride, pit and fissure closure, oral health education for pregnant women, etc.

myth 6: if you often brush your teeth with medicated toothpaste, your teeth will be very good.

in fact, the long-term use of drug toothpaste is easy to cause the imbalance of normal oral flora and oral mucosal diseases. Therefore, drug toothpaste is generally used properly after routine oral treatment. If drug toothpaste is needed, it must not be used for a long time.

How should we protect our teeth?

1. Develop good oral cleaning habits: brush your teeth in the morning and evening, clean your mouth after meals and before going to bed, and reduce the formation of dental plaque.

2. Regular oral examination: the protection of teeth cannot be less. We must go to the hospital regularly to check the health of teeth.

3. Calcium supplement: calcium supplement can strengthen teeth. It is recommended to eat more bean products and milk to effectively protect tooth health.

4. Daily living habits are the most important factor in preventing oral problems: the water temperature of brushing teeth is the key, and relevant experts suggest that we should use 37 & deg; Warm water around C is the best, and when brushing your teeth, do not brush horizontally, but brush vertically. Brushing your teeth should not be too hard, which is easy to cause problems such as loose teeth.

5. Although diet is directly related to oral problems such as tooth decay, some foods can also clean the oral cavity: 1) bromelain in pineapple is a natural detergent with the effect of removing dental plaque. Citrus fruits such as oranges can also stimulate saliva secretion and naturally clean teeth. 2) Dark green leafy vegetables such as, spinach and lettuce contain a series of minerals such as magnesium, which helps to form an antifouling film on the surface of teeth and plays an important role in keeping enamel white.
