Teeth damaged teeth against improper

Dental experts today warned consumers, whitening, tooth repair to guard against two errors.

Undue harm teeth whitening.

The white "tetracycline" for example, at this stage, many clinics will take the crown finely ground, then put on the practice of porcelain crown. Although such beautiful teeth, but over time the problem will be revealed. Grinded teeth tend to become sensitive, fragile, porcelain crown is easy on the gums of the metal part of the stimulus, the black gums, shrinking.

According to experts, is currently the safest and most natural teeth whitening method is to use the "3D white patch." Use this method to be first out of a thin layer of the tooth surface friction (about the thickness of two pieces of paper), then use the 3D camera to dental equipment take as the mouth, after carving out the worn part is completely consistent with the tooth enamel of artificial restorations, the chip embedded in this layer of whitening teeth.

Materials such as silver amalgam fillings.

Silver amalgam restorations with the practice of tooth decay have been eliminated in developed countries. Unsightly amalgam color itself can not be closely integrated with the teeth, could easily lead to secondary caries and strength, and heavy metals will have a negative impact on the body. Therefore, the experts recommended close to the tooth structure of the material - VITA artificial enamel porcelain wood block. This is a vacuum with compressed ceramic powder fired Knowledge of tooth whitening ceramic block out material, which after a slow cooling, density, easily broken, good light transmission, repaired the teeth look very natural. After ten years in abroad, the clinical evidence, the degree of wear of natural tooth enamel and 98% similarity.

Why is becoming larger and yellow teeth?

In the etiquette expert eyes, teeth, is a woman's business card, if your teeth neat, white, fresh breath, you must be an educated lady. But if your teeth yellow, your impression of people being reduced.

Fluorine on the one hand increase the tooth enamel, making it more robust, the other will make the teeth gradually turn yellow. Mineral water contains large amounts of fluorine, drink too much, let your pale white teeth! U.S. oral health experts advice is: Drink at least 1000 ml per person per day white water, including mineral water intake should not exceed 300 ml, the remaining 700 ml, you can drink pure water or boil tap water.

There are a lot of tea polyphenols oxides, long-term tea, make the teeth yellow. The study found that black tea polyphenols in the highest oxide, followed by black tea, tea, barley tea polyphenol oxide content in the lowest, you can rest assured that drink! In addition, the longer dental equipment cooking tea, the role of the lower oxide, in order to ensure that they have white teeth, you may be extended tea time.

Coke syrup and carbon dioxide gas components, drinking too much sugar will cool to tooth surfaces, making it the color black. Studies have found that drinking one liter of Coke a day, two years after the tooth surface enamel acid etching will be cut in half. In carbonated beverages, dark cola greatest damage to the teeth, orange soda followed, in general, the color the more light the drink, the more secure, I suggest you choose a transparent color's Sprite.

In the American Dental Association recently released the "Top of stained teeth" on the main component of turmeric curry than nicotine, ranked first, the greatest impact Adverse impact on dental health habits on the tooth color. Research indicates that turmeric stain on the role of teeth is almost irreversible, is a veritable "white teeth nemesis." If you really feel like the kind of spicy, I suggest you choose the weakest force dyed green curry, red curry to avoid the strong force and the yellow curry.

How long is the life of ordinary porcelain teeth

In China, due to economic conditions, most of the friends of porcelain teeth need to do or choose the ordinary porcelain teeth. Therefore, the length of life of ordinary porcelain teeth become an issue of concern to the majority of U.S. dental problems of people.

In general, a physician through formal rigorous, standardized, and correct operation, design, production of porcelain teeth, worn in the mouth of life, ordinary porcelain alloy obtained by the study, 65% can use more than 20 years, this but also a resistance in the patient's own care. If you do not brush your teeth, eating lightly something, it will greatly reduce its service life.

A good porcelain teeth, depends on the operation of clinical engineers specification, the correct design, theory and professional repair technicians in close co-ordination, otherwise the repair will be difficult to achieve the desired effect, the current porcelain teeth, in China's large small primary hospital has been widely promoted and used, but not everyone can do, and some teeth dental equipment too small (was small and conical), defect is too large, when aggregated with doctors too large, common bond material, so, pretty soon wear porcelain teeth will bonding, off, leading to irreversible failure of the repair, the opposite of the master if the serious indications, take appropriate measures, under normal operation, the application of high-performance bonding agent, porcelain teeth in the mouth is not loose, you can rest assured that use.

Therefore, the life of ordinary porcelain teeth were selected material, the doctor's daily operations and the use of personal influence, so I want to let ordinary porcelain teeth longer, then we must look to the regular professional hospital medical professional production, so that Cosmetic Dental Crowns information can only be guaranteed on the same time with their daily maintenance work, then the life of ordinary porcelain teeth will be very long or even life-long.

Porcelain teeth do not mean everything is all right

Many friends made ​​porcelain teeth that once made ​​porcelain teeth after that everything can, and hospital dental center experts say: do porcelain teeth how to care that this has become a required course for us, because to do the porcelain teeth does not mean that everything will be fine. Here we take a look at how to protect the porcelain teeth.

After doing a professional porcelain teeth doctor will tell us not to bite too hard food, especially not with dentures eating sugar cane, such as walnut or something. Not that hard porcelain teeth could eat something, but often with dentures biting hard things, not only will shorten the dental equipment life of dentures, but also easily lead to porcelain tooth fracture. Porcelain dental porcelain powder is sintered at high temperature, so that if there is fracture, is often not easy to repair, dentures usually need to be removed after the redo.

In addition, the Hospital Dental Center experts say: If it is beginning to wear porcelain teeth, eat soft foods, avoid eating cold hot food, avoid stimulating pain can be Bad breath is a precursor to serious illness normal after about two weeks after eating normal food fit to eat. And the early stages of wear and repair of porcelain teeth than before, up and down the cusp alignment may change, eat slowly, and gradually adapt to, bucco-lingual mucosa in order to avoid bites.

Effective preventive measures bad breath

Effective preventive measures bad breath

Main causes of bad breath in children: oral cavity volume of milk or food debris accumulated failed to wash; teeth with large cavities, there is corruption in the dirt; dental caries infection, bleeding, or fistula of dental caries pus; suffering from dental equipment blood diseases; indigestion.

Pulp necrosis and root canal treatment

Root canal therapy is the root canal by removing the necrotic material, proper disinfection of root canal filling, root canal to remove the contents of the periapical tissue of adverse stimuli, prevent the occurrence of periapical lesions or promote the healing of periapical lesions a treatment method. Pulp necrosis and chronic pulpitis (including periapical granuloma, periapical abscess, periapical cyst), pulp and periodontal syndrome, systemic disease should not be in need of treatment or tooth extraction and teeth are being retained are indications for root canal therapy.

In the implementation of root canal therapy, there are two methods. Double or multiple methods: first, the system wide open marrow, marrow washing, removal of necrosis, gangrene of the pulp, expand the root canal, root canal again, rinse clean, dry sealed dental equipment sterile drugs after about 2 to 7 days; referral without obvious response, that is, remove the sealing material, filling the root canal; if there are significant reaction, can be re-sealed sterile drugs, next time root canal filling. One law: the system wide open pulp, rinse, and expand the root canal, then root canal filling, once completed.

The preservation of the many methods of treatment of teeth, root canal therapy the best long-term efficacy and has been called "high-rise buildings" - the basis of post-core crown. Therefore, the residual crown and root tooth, root canal therapy is the only choice of treatment.

Pulp necrosis, root canal therapy is the process of root canal treatment of a doctor with specialized equipment through the complete removal of infected pulp Prevention of oral mucosal disease and dentin infection and toxic decomposition products, closely filling the root canal, isolated bacteria into the root canal re-infection, to prevent occurrence of periapical lesions or promote the healing of periapical disease.

The good effect of root canal treatment

Many people may not know, seems on the surface of the teeth very hard, in fact, hollow. The hollow structure of the internal teeth called "root canal." Filled with dental nerves and blood vessels to maintain a nutritional and sensory function of teeth. Tooth decay, tooth trauma, cracked and other factors, are prone to infection inside the root canal. When the root canal tooth nerve What circumstances do root canal treatment compression by inflammatory secretions, it will cause pain. Because it is very hard tooth tissue, and the root canal and very narrow, not expand, so the pain is very severe, injections, medication can not solve the problem.

   

Root canal treatment for toothache generated cause tooth nerve pain processing, long-term the best way to keep the teeth. Treatment, the doctor first drilling dental equipment a hole in the tooth (in the case of anesthetic), reducing the pressure inside the root canal, the release of inflammatory secretions. Immediate effect, the patient immediately feels teeth hurt. Then, the doctor will use professional equipment to root canal infection and necrosis of the nerves, vascular tissue cleared, and then a special tool to shape the root canal expansion, sterile clean.

   

Finally, the other teeth when no symptoms, then a special material to be very dense root canal filling, so that the shape of the teeth restored intact.

Dental root canal is a project to save the tooth

Dentist will try to rescue and save every tooth, root canal treatment is a "save the tooth projects."

      

The process of root canal treatment Root canal treatment is a doctor with special equipment - root canal microscope, by the complete removal of infected pulp and dentin infection and toxic decomposition products, after root canal irrigation, disinfection and tight filling the root canal, the bacteria isolated into the root canal re-infection, to prevent the occurrence of periapical lesions or promote the healing of periapical disease.

      

Clinical reports of root canal therapy more than 90% success rate, is the best treatment to save teeth. When a tooth has spontaneous pain, tissue necrosis or dental equipment internal teeth, you need root canal treatment.

     

Root canal treatment include: commonly known as the pumping nerve, and removal of necrotic tissue within the bacteria, and root canal expansion. Teeth with a special glue to close the root canal filling.

      

Root canal therapy to eliminate the bacteria's only chance, as long as through the acute inflammation phase, it would not have the phenomenon of pain. (If you do not have root canal treatment, only pumping nerve, the pain may resolve temporarily, but as long as bacterial regeneration, the phenomenon of pain will happen.)

      

Main advantages: retains root, without extraction, root canal into the heart to The ideal solution for dental cosmetic restoration cook after braces, and had teeth as easy to use, do not pull the tooth because the need to produce a dental bridge, save time and money.

Titanium ceramic dental material?

Titanium dental porcelain is a type of porcelain teeth, porcelain teeth, titanium is now increasingly being loved, bad teeth, people who use titanium porcelain teeth, the ratio is increasing, so that we to specifically look at titanium porcelain teeth, porcelain teeth and take a look at the price of titanium.

Dental Center experts: the composition of titanium dental porcelain, in fact, not all dead, and titanium.

However, due shortly after the teeth have moved slightly loose, and there is a tendency to return to its original position, if not do a good job-related measures can easily lead to dental orthodontic relapse.

Porcelain teeth upstart - all porcelain teeth

Have a nice neat white teeth is one of the symbols modern ten healthy. Dental porcelain has long been a fast and effective repair of carious teeth discoloration way. However, metal ceramic metal ions within the body will produce adverse reactions, such as black gums, bleeding gums, shrinking; and the crown should be the presence of the metal, translucent, natural tooth color and dental equipment shape and there is a big difference, more light produced in the "gray" effect. Therefore, oral health care community has been working to change that state. The international dental community is one of the latest popular within the metal-free porcelain dental crown - all porcelain teeth.

All-ceramic tooth because of its superior performance in some developed countries a wide range of applications, but also the repair material of choice for patients. Its superior performance in:

1. No black line the edge of the gums, no heavy feeling, no swelling and bleeding gums, so you really feel the porcelain teeth from your own gums grow out of.

2. With real teeth to match the transparency, no longer in the light "shining blue tooth" embarrassment.

3. Porcelain with metal teeth comparable compressive 10 minutes there is no dental caries strength, do not have to worry about porcelain cracking phenomenon.

4. No adverse effects of metal ions leaking your health.

5. Teeth less, greater organization retain their teeth.

Acquired factors missing child's teeth

To give the child a pretty neat teeth, it is necessary to correct their bad habits as soon as possible. Acquired factors more than innate factors.

1. Use of plastic pacifiers method is not correct. Feeding to the child, if the bottle top or front of the location is too supine infant feeding, it will suck the lower jaw forward, falling to the mandible and lower dental arch forward, pressure on the arch, to form the next row dental equipment prominent front teeth.

2. Premature loss of deciduous teeth or too late loss, but also can cause the teeth look uneven.

3. Patients not treated deciduous teeth, or due to trauma and loss, both sides of the teeth will shift to the gap, making the gap smaller, after the permanent teeth come from a long gap, because there is not enough room for growth and uneven.

4. Tonsillar hypertrophy or leaving the nose and shortness of breath, nasal sick, use mouth breathing affect the growth of the teeth. As to sleep with his mouth open, the flow of air through the mouth, causing uplift up on the palate, dental arch on the left and right sides also will narrow the front of the protrusion of the upper arch, the front teeth grow not only forward tilt, and arranged in disorder.

5. Tongue biting tongue. Initiation of the front teeth will be when there is mild gum discomfort or itching, and some children would love tongue, licking the teeth, gums or What primary and secondary prevention of dental tongue biting. A long time, so that is blocked by the initiation of teeth, upper and lower front teeth can not touch each other, forming a front tooth opening deformity.

6. Biting finger biting a pencil. Some children like to bite your finger, or the title in pencil between the upper and lower teeth, resulting in protrusion on the front teeth and lower front teeth shorter, the performance of small-mouth jaw deformities.

Adolescent oral health practices

1. Premolars and molars of the chewing surface is uneven, there are some natural fissure and fissures. Plaque accumulation in these parts is easy and brush your teeth or with other mechanical methods is not cleaned, so the high incidence of fissure caries. Dentists can use the pit and fissure sealant to close the fissure, to prevent the accumulation of plaque, which can effectively prevent the occurrence of fissure caries.

2. Puberty gingivitis gingivitis occurs in adolescence adolescent teenager, mainly the anterior lip side of the interdental papilla was spherical, gum edema, redness, shiny, brushing teeth or bite food easy bleeding.

Porcelain teeth to correct teeth need attention must find an experienced professional medical operation, the doctor's experience is different, in particular dental operation there will be a big difference. Because there is a correction made ​​porcelain teeth or teeth adjacent to the enamel surface of the case, too much teeth or go to the enamel of the teeth will cause damage to teeth Root canal treatment on some of the problems enamel or lack of it may not reach the desired correction. Therefore, porcelain teeth to correct the teeth of the doctor's experience and technology has a higher challenge.
