The fastest and most effective method of tooth whitening 1 1, cold light whitening teeth.

Applicable people: tetracycline teeth, aging discolored teeth, dental fluorosis, tea stained teeth and other discolored teeth.

Principle: Cold-light tooth whitening is to transmit high-intensity blue light with a wavelength of 480-520nm through optical fiber, pass through two special optical lenses with 30 layers of coating, and then undergo special optical treatment to remove all harmful ultraviolet rays and infrared rays, and quickly produce redox effect with whitening agents such as hydrogen peroxide and silicon dioxide with a diameter of 20 nm. Through the tooth tubule, the pigment attached to the surface and deep layer of teeth is removed, so as to achieve the effect of whitening.

Advantages:

No irritation and no pain: no heat will be generated during the treatment, and the hydrophilic materials used have desensitization components, so patients will not have irritation and pain during the cold light whitening surgery.

Deep decolorization: It can not only remove the pigment deposition on the tooth surface, but also enter the deep layer of the tooth to achieve the decolorization effect.

No harm to teeth: the low-temperature cold laser avoids the stimulation to teeth nerves, and the medicine does not touch gums and will not cause any damage to tooth structure.

Fast and safe: low temperature and cold light will not cause irritation to teeth and nerves. The traditional bleaching agent can make teeth allergic, while the whitening agent with cold light whitening is mainly composed of hydrogen peroxide, which will not cause allergic phenomenon.

Note: Within 24 hours after cold light whitening teeth, teeth are easily infected with colored substances. You must avoid drinking tea, coffee, cola, red wine, berries and other drinks, and avoid using colored toothpaste and mouthwash. Avoid smoking; It is suggested that patients use whitening toothpaste, which can reduce the recolor of food after cold light whitening; Try to reduce dark food in the diet; Pay attention to oral hygiene, brush your teeth and rinse your mouth in the morning, noon and evening to keep your mouth clean.

2. Ultrasonic tooth cleaning

Applicable people: calculus, yellow teeth, mottled teeth, etc.

Principle: Ultrasonic tooth cleaning is an efficient, hygienic, convenient and comfortable method for cleaning teeth. It uses high-frequency and high-energy vibration generated by ultrasonic waves to crush dental calculus and dental plaque on the surface of teeth through the smooth working head of ultrasonic cleaning machine, and then washes away the gravel and dental plaque by water mist generated by the cleaning machine.

Advantages:

Convenient and time-saving: it usually takes about 30 minutes to finish the supragingival scaling of all oral teeth.

Safe and efficient: under the correct operation, ultrasonic tooth cleaning has less damage to the tooth surface than traditional tooth cleaning. Only under a magnifying glass can you see the fine lines left on the tooth surface. If you have loose teeth and dentin allergy, you may feel pain and discomfort during cleaning. However, don't worry at all, this kind of pain is very mild.

Tooth protection and tooth health: Because ultrasonic tooth cleaning has different external vibration and internal massage functions, it can not only remove dirt and dirt, but also massage teeth inside and outside, which is beyond the reach of general massage. Therefore, ultrasound plays an unusual role in tooth protection and health care.

Micro-massage produced by the mechanical action of ultrasonic wave can improve the metabolism and regeneration ability of tooth tissue, improve the growth state of teeth, not only whiten teeth, but also repair the inside and improve the outside of diseased teeth.

Insufficient: Ultrasonic scaling is easy to miss tartar, so after operation, we will carefully check whether there is missing tartar with a probe, such as some small tartar and adjacent tartar, and also clean it with manual instruments.

Precautions: Pacemakers and patients with hematological diseases such as acute leukemia, aplastic anemia and AIDS are prohibited from ultrasonic tooth cleaning; Diabetes, hypertension and uncontrolled acute periodontal abscess are also not suitable; Some people will have allergic pain, which is exciting and lasts for a short time. The pain will disappear after the stimulation is removed, and generally no special treatment is needed. It can gradually disappear after 2 weeks 1 month.

3, laser whitening teeth

Applicable people: yellow teeth, tetracycline teeth, exogenous pigment teeth, especially adult melanin caused by tetracycline, and dark smoke spots and yellow teeth left by smoking all the year round.

Principle: The principle of laser tooth whitening is that the bleaching drug is coated on the cleaned and pretreated teeth, and then the bleaching drug is decomposed by laser catalysis, so that it produces free oxygen atoms with high activity and can go deep into the teeth, which are widely combined with pigment molecules and then released; At the same time, the penetration depth of laser is relatively large, which can continuously remove the pigment molecules in the decomposition products of deep tooth decay, thus playing the role of bleaching from the inside out and achieving the effect of tooth whitening.

Advantages:

Safe and fast: laser tooth whitening can complete the whole oral tooth whitening in less than 30 minutes, and the time of irradiating each tooth is less than 1 minute, which greatly reduces the possibility of overheating or sensitivity of teeth.

Painless and non-irritating: Laser tooth whitening treatment will not hurt, so anesthesia is not needed. After treatment, due to the continuous action of the drug, the teeth will have a slight tingling sensation that day. In most cases, it will get better after a few hours that day, and you won't feel uncomfortable.

Efficiency: The efficiency of laser tooth whitening is 29.5 times that of bleaching gel alone. The treatment handle designed according to the principle of ergonomics can treat four teeth at the same time. After each treatment, the tooth whiteness will be improved by 3 ~ 4, and the general whitening effect can last for 2 ~ 3 years.

Simple and convenient: laser tooth whitening is controlled by computer, and the operation is simple. The whole machine is small and exquisite in appearance, easy to move, convenient and fast. The whole machine is small and exquisite in appearance, easy to move, convenient and fast.

Disadvantages: Laser tooth whitening is to smear bleaching drugs on cleaned and pretreated teeth, and use laser to catalyze the decomposition of bleaching drugs, so it is easy to appear calcified white and dull after tooth whitening.

Precautions: it is recommended to choose white or colorless food within 24 hours after laser whitening treatment; Try to avoid eating red wine, cola, coffee and tea, soy sauce, mustard, ketchup, Chili sauce and irritating foods that are too cold or too hot; Avoid using colored toothpaste and colored mouthwash; Avoid smoking.

4. porcelain teeth

Applicable people: tooth discoloration such as dental fluorosis, discolored teeth, tetracycline teeth, fangs, enamel hypoplasia, etc.

Principle: Porcelain is divided into all-ceramic glazed porcelain veneer, all-ceramic crown and all-ceramic crown. Porcelain teeth are a permanent restoration method. High-strength alloy is made on the treated root, and a layer of low-melting-point porcelain powder similar to the color of natural teeth is baked on its surface, sintered and melted in a vacuum high-temperature porcelain furnace, and finally bonded to the teeth. Its color can be matched according to one's own teeth to achieve basic unity, and it can quickly restore the shape, function and beauty of teeth.

Advantages:

Strong sealing: Porcelain teeth have strong sealing, and will not have odor or pain after covering broken teeth for several years, like other Kouga or gold teeth. Because the porcelain teeth are located under the gum 1mm, special water-insoluble bonding materials are added to ensure the sealing of the porcelain teeth, and prevent saliva and food from entering the porcelain teeth through analysis and corroding the real teeth.

Ideal and durable color: the color is more ideal, closer to the color of real teeth, and it will never change color and there will be no spots. Whitening teeth has obvious effect and high durability.

Not easy to be allergic: Porcelain teeth have excellent corrosion resistance due to the chemical inertia of the material, which is not easy to make human tissues allergic, while ordinary Kouga will have a black edge on the gingival margin after wearing for a period of time.

High hardness: the hardness of porcelain teeth is higher than other materials. After testing, it can completely bear the chewing strength in the mouth. As long as it is not too hard food, such as walnuts, you don't have to worry about the broken porcelain teeth.

Note: the age of porcelain teeth is between 20 and 60 years old. Porcelain teeth will be crushed by pressure beyond their stress range, so don't bite too hard food. The joint between porcelain teeth and abutment is easy to accumulate plaque and form tartar, so we should pay attention to cleaning, you can floss your teeth and go to the hospital for regular inspection and cleaning.

The fastest and most effective way to whiten teeth 2 1, whitening toothpaste

Applicable people: long-term drinking of tea, coffee and red wine, or tooth discoloration and yellowing caused by smoking.

Insufficient: the effect of deeply discolored teeth is not obvious enough; The cycle is long.

3. Ultrasonic toothbrush

Applicable people: there are many dental problems, but the tolerance is high, so ultrasonic toothbrush can be used first.

Principle: Using the cavitation effect of ultrasonic energy in periodontal tissue, it can remove periodontal germs and impurities, and its cleaning range can cover all parts of periodontal tissue, accelerate blood circulation, promote metabolism, inhibit tooth inflammation and gingival bleeding, and prevent gingival atrophy.

Advantages: convenient use and strong cleaning effect. It can penetrate into teeth and even gums that can't be brushed manually in all directions, directly kill oral bacteria and block the generation of dental plaque.

Insufficient: Ultrasonic toothbrush belongs to high-frequency vibration toothbrush, and it is best not to be used by people with serious dental problems and low tolerance.

4, denture whitening method
