Some of my dental problems
What age number of people who have dental?
The number of men and women of the dental and more?
How many times do the average annual dental care is the best?
Trouble attach a small paper, talk about reading the views of dental problems and how to protect the teeth.
To protect the teeth, we must first understand the structure of teeth. Teeth are the hardest organs in the body. Are biting cut, tear, grind food and to help pronunciation and so on. Human life has two teeth: one for the teeth, a total of 20 on each jaw 10. After birth around about six months of eruption of a homogeneous two and a half years, from 7 to 12 years of age, primary teeth have exfoliated; another deputy for the permanent teeth, a total of 32, the upper and lower jaw of the 16, from 6 years of age , was gradually replaced teeth, in addition to 12 years after the first 3 molars, the eruption of permanent teeth all. 3 molar eruption usually after the age of 20, also known as wisdom teeth. Wisdom teeth can also be no life, so 28 to 32 permanent teeth were normal.
Teeth divided crowns, neck and root of three parts. Crown that we can see part of the teeth exposed on the outside part of the gums. Surface covered with a layer of enamel crowns, enamel is the hardest tissue in the body, hardness similar to quartz. Root is embedded in the upper and lower jaw alveolar process in part. Coated with a layer of root cementum. Between tooth crown and root neck is slightly smaller among some, outsourcing gums. Constituted mainly by the quality of dental teeth, called dental cavities inside the cavity. Teeth cavity filling a living connective tissue, nerves and blood vessels, collectively known as the pulp. Blood vessels and nerves from the apical hole and out. Suffering from dental caries, when the bacterial corrosion of the enamel and dentin into the pulp cavity, stimulate nerves, the pain. (See Figure 37) students to protect their teeth, to do the following:
1. To develop good brushing habits. Rinse with warm water after a meal, brush your teeth morning and evening time. The frequency of brushing is not too much more it will damage the teeth, brushing time should not be too long. Brushing should pay attention to the right way: down the teeth, bristling brush, brushing the inside painted outside. Not scrub back and forth horizontally, otherwise it will damage the gums.
2. Always pay attention to dental health, and protect teeth. Usually to eat less candy. Do not eat candy, especially before going to sleep, prevention of dental caries. Also, pay attention to the usual health habits, not to bite fingers, do not bite a pencil top foreign body, no tongue lick teeth.
3. If the tooth is sick, should be timely medical treatment. In case of bad tooth decay and should be repaired or removed.
To achieve the above points is not difficult, the key is to persevere. Students would like to have a healthy and beautiful teeth.
Have good oral health is not the only way to healthy beautiful teeth. Diet also plays a significant role. Here are some suggestions to help you have a beautiful smile!
Your teeth: the main indicator of health and beauty
Teeth so that we can enjoy a wide variety of food! Healthy teeth allow us to chew hard food cynical, meat, raw food, fruit ... ... good chewing gum can enhance the strength, stimulate saliva production, and their participation in the process of digestion, the teeth play a sterilization role. In addition to genetic factors, the color of our teeth, and hardness also depends on the dental health and eating habits.
In order to maintain dental health: a balanced diet!
Balanced diet, adequate distribution of the meals of the day (to avoid snacking, four meals a day should be arranged in: Breakfast, lunch, dinner and snack time) on the strong teeth are very favorable. In fact, this enables us to better resist the stimulation of teeth: enamel erosion, dental caries ... ... fresh foods, such as carrot, red radish, or Apple is chewing at the right time, the friction surface of the teeth, in fact, from to the role of clean teeth. In addition, lipids, certain proteins (casein cheese), minerals (phosphorus, calcium, fluoride ... ...) of vitamin D also has an antibacterial effect, limiting the salt discharge enamel.
In contrast, snacks, especially those "soft" food, carbohydrate food (candy or sweet drinks, bread, pastries ... ...) or acidic foods (soda, fruit, fruit juice), usually increases the risk of tooth decay. Sugar can be converted to acid, the acid could damage the surface of the tooth enamel. If possible, every time after eating food carefully clean teeth. If there are no conditions, but also can seriously mouthwash or chewing a piece of sugarless gum. In fact, any increase in saliva flow rate are reduced risk of dental caries. To point out that excessive consumption of coffee, tea and smoking too much may make the teeth yellow.
Four dairy products make teeth stronger
They are what we need the best quality of calcium and phosphorus sources, tooth enamel and root support for the main mineral of bone material. Primary teeth begin to mineralize the first four months of gestation, stone tooth mineralization began in the first year of birth. After tooth formation, enamel updated and has been maintained. We should drink milk, it is best not to drink sweet drinks. Dairy products (yogurt, etc.) also brought calcium, phosphorus and vitamin D, which will increase the absorption of calcium and phosphorus. Finally, casein, the major milk protein, can limit the discharge of excessive tooth enamel mineral. The practice of the past, people on the good: usually eat dessert after eating cheese, thanks to the restrictive effect of casein and milk fats, reduce the acid secreted carbohydrates.
Drink mineral water, it is a natural source of fluorine
Natural mineral water to meet the demand of the human body for the fluoride. Fluoride can increase the tooth enamel and teeth, protect teeth from microbial erosion. Most of the mineral water contains 0.3 milligrams per liter of fluoride, but also some content of up to 8 milligrams per liter. We can also see the fluorinated table salt. For pregnant women and children, as well as made use of fluoride tablets (based on age, 0.5 mg to 1 mg). In tea, fish and some vegetables (spinach, red radish ... ...), also contains fluoride quality. However, excessive intake of fluoride quality (more than 2 mg per day) may cause the teeth black.
Use of the benefits of chocolate and sugar-free chewing gum
In fact cocoa contains tannin, quality and calcium fluoride. Protection of these three substances are involved in the work of the teeth.
In the "sugar free" chewing gum, the sugar is replaced by the sweetness of polyols, however, does not cause tooth decay: xylitol to play the role of sterilization will help to reduce dental plaque, as well as sorbitol (synthesized from glucose or fructose sugar, sweet as artificial flavoring agents). Therefore, a 2.2 g sugar-coated chewing gum containing only 3.8 calories.
The number of men and women of the dental and more?

Dental Consultation
Excuse me, my father, 60, left the following teeth, has lost three teeth. Is a one off, the pre is a little sore, and then slowly getting worse and worse, and finally loose teeth, and then slowly more and more loose, the final out. Each tooth pain tooth to be more than a year, lost a tooth after the tooth next to it will repeat the previous status of a tooth. I do not know what reason? It can prevent dental pain and tooth loss continue?
May be good periodontal, periodontal supporting tissues of teeth mainly, with age, some back teeth Zhou Huisheng rational absorption, coupled with stimulation of periodontal disease, absorption of double loss could eventually lead to loose teeth. The main source of stimulation periodontitis dental calculus, dental calculus formation and maintenance of oral hygiene, personal, individual differences in food preferences and relevant. Department of periodontal root absorption that exposure will cause teeth to become sensitive, especially for hot and cold stimulation. With the deepening of periodontitis, the disease may enter the root through the root tip within the medullary cavity, causing inflammation of the pulp, characterized by spontaneous pain, the pain will become very serious. Your father to recommend to the Department of Oral and Dental Hospital, Periodontal Endodontics look. Periodontal therapy can control the loose teeth, mainly clean teeth. Endodontic therapy can relieve pain, mainly in root canal treatment. However, the specific situation or need to go to hospital when you see it.
Perio-endo lesions, the proposed scaling, as the case for further treatment

City children suffer from dental caries 65% -70%
Every parent wants their children to have a good dental health. So, what common children's dental problems, the parents whether the existence of errors in cognitive, child dental should the how? Recently, Jiangsu Provincial Stomatological Hospital, physician, director of children's dental Professor Zhu Lingfu remind parents: dental caries in children is the key to early detection, early treatment and regular inspection, preventive dental, dental oral health needs of love since childhood.
"Children's dental caries has long been the most common oral diseases. Studies show that children suffer from tooth decay rate of the city 65% -70%." Zhuzhu Ren said cavities commonly known as tooth decay, cavities, is an extremely common and the incidence of high disease. Caries can occur at any age, especially in higher prevalence among young people. The incidence of dental caries in children and living environment not only material conditions, but also with the development of tooth structure itself, eating habits and oral health related to the situation.
Caries first appeared, there is no sense in children, but does not cause pain, and some parents even "kids do not need fillings," "Anyway, they wanted to change teeth" and other errors. As everyone knows, if not promptly treated, may cause pulp disease, when inflammation continues to develop into the root, or even cause systemic disease.
Adult children do not appear typical of the general dental teeth spontaneous pain, night pain, but showed significant swelling of the gums. "Therefore, when parents help their children brush their teeth, if found to decay with children should immediately see dental, early treatment and delay in treatment will increase the child's pain." Zhu Zhuren introduced in relatively shallow cavities, the time to can be mended. Involving dental nerves, causing pulpitis to do endodontic treatment, the treatment at least 2-3 times to make good. If the lesion further development, was severely damaged teeth, the teeth can not keep the gap to be done after removal of retainer.
Parents are very concerned for the prevention and treatment issues, Zhuzhu Ren said that parents must pay attention to oral health among children, morning and evening brushing, mouthwash after meals, master the correct method of brushing. Not a partial eclipse, not unilateral chewing. Meanwhile, on a regular basis for an oral examination is also essential, typically 3-6 months.

Is it the signals for big teeth dental?
[Abstract] everyone has teeth, healthy teeth, gums, full, lived gingival papilla filling teeth, is difficult to see with the naked eye the existence of teeth. Beijing You An Hospital, Capital Medical University, Department of Stomatology, director Chen Shizhang also noted: As women enter middle age, the loss of bone calcium in the beginning, especially after menopause, there will be widened between the teeth and so on.
Everyone has teeth and healthy teeth, gums, full, lived gingival papilla filling teeth, is difficult to see with the naked eye the existence of teeth.
There are two reasons for the increase between the teeth. Some people may be inherent in some teeth, too small, too large so that some parts of the teeth is normal. Pathological teeth increased, it is usually caused by periodontal disease. In particular, the persistence of chronic inflammation, recurrent, resulting in alveolar bone resorption, gingival recession. To a certain degree of gingival recession, root exposure can lead to loose teeth, or even fall off.
Beijing You An Hospital, Capital Medical University, Department of Stomatology, director Chen Shizhang also noted: As women enter middle age, the loss of bone calcium in the beginning, especially after menopause, there will be widened between the teeth and so on.
As a result, the teeth will feel the pain experienced hot and cold sweet and sour. Meanwhile, the exposure of the root is also vulnerable to the accumulation of food debris and plaque occurrence of dental caries. So before and after menopause, women especially vulnerable to dental caries, gingivitis, periodontitis and other dental problems. In addition, menopausal women saliva secretion decreased, weakening the role of oral self-cleaning, coupled with the impact of changes in endocrine levels, many women will experience dry mouth, astringent, burning tongue and other mucosal discomfort, but also prone to recurrent mucosal ulcers, flat moss and other oral mucosal diseases.
So, people with big teeth, how to prevent oral disease should it? Chen Shizhang said: first of all to pay special attention to maintain oral health, to develop sooner or later, the habit of brushing and mouthwash after meals, preferably in the brush while flossing; the same time, every morning and evening can be "call-tooth" training and massage the gums, which can contribute to periodontal blood circulation, increase the resistance of the gum tissue, slowing alveolar bone atrophy; In addition, menopause oral paresthesia occurs, can add some calcium, vitamin and so on. Into the post-menopausal women at least a year to see plays dentist; Once loose teeth, chewing and weak, should seek medical advice.

No dental extractions
Three doctors never easy extraction Evening News, because they know the consequences of severe tooth extraction, if you've got teeth, going to the dentist, the worst result, only one tooth, such as mild symptoms, can kill the tooth nerve , although to avoid dental deterioration, but means Bingya not always restore the health of the state, will take a heavier extraction, extraction appears to be simple, but great harm. 1, the real teeth and dentures 50% difference in chewing ability. Extraction means that the decline in ability to chew. The rate of loss of teeth and tooth extraction is proportional to the amount that you are pulling more teeth, loose teeth fall off faster. 2, dentures because there is no sense of ability. Most of the food will make you lose the fun. This is the doctor does not extraction of the secret.
Dental non-extraction treatment without medication
Because every day the magic brush of a toothpaste containing minerals, work area 53 Old Lee West, just one month, loose teeth, sore allergy disappears, and even gum recession, teeth growing, before dinner Seya's wrong with the old address, before the talk of the town's dental constantly, to the hospital, doctors get a long drill pliers that pretend to pull the tooth.

Experts pointed out: Under normal circumstances, their teeth will continue to repair a small amount of damage, but once the tooth's "defense system" is broken or serious loss of minerals like calcium, bone loss, like tooth becomes loose, the bacteria will will slip into the tooth dentin below, so that loosening teeth, tooth decay, gum recession, teeth and so the increase to strong teeth will replenish minerals. "NVC" Glister oral paste, oral, MD, United States 8 years after Redman latest scientific findings, the use of nano-method to extract the shells from the deep sea minerals, mainly sand phenol factors, minerals, calcium, bone 128 collagen and other nutrients, as "medical osteoblasts," just like mine every day Note strong teeth, dental cavities to fill the gap. Add to shrinking gums become strong after the full nutrition, enabling support for the teeth, so allergies, gingival recession, bleeding, tooth decay and other problems in order to solve.
