What Is Tooth Eruption?

When teeth are stimulated by cold, heat, sourness, sweetness, and mechanical effects (friction, biting hard objects), a sudden sore sensation may occur, or it may flash, or last for a short time. When the irritation is removed, the soreness Will disappear.

Sensitive teeth

When teeth are stimulated by cold, heat, sourness, sweetness, and mechanical effects (friction, biting hard objects), a sudden sore sensation may occur, or it may flash, or last for a short time. When the irritation is removed, the soreness Will disappear.

When the doctor examines the teeth, he can also use the probe to find the sensitive points on the teeth.

Dental sensitivity (Dentine hypersensitivity) is the external stimulation of the teeth, such as

Who can make

The main manifestation is irritation, which causes soreness when brushing teeth, eating hard objects, sour, sweet, cold, and hot stimuli, especially the most sensitive to mechanical stimuli. The most reliable diagnostic method is to slide a sharp probe on the tooth surface to find one or more allergic areas. Foreign countries reported a mechanical stimulator that uses screws to adjust the pressure of stainless steel needles to test the sensitivity of teeth, and also uses an electronically controlled thermometer to test the person. However, so far, the sensitivity of the teeth can only be expressed by the subjective feelings of patients.

In the pathogenesis of dental hypersensitivity, hydrodynamic theory is widely accepted. According to this theory, an effective treatment for allergies is that the dentin tubules must be closed to reduce or avoid fluid flow in the dentin. Due to the spontaneous desensitization process of this disease, it is extremely difficult to evaluate the efficacy of any drug.

Common treatments are:

1. Laser treatment: Er: YAG laser with a wavelength of 2940, with an energy of 100mJ and a frequency of 10HZ, is a safe threshold for the treatment of dentine hypersensitivity. The mechanism may be that the thermal effect of the laser acts on the dentinal tubules, which can instantly close the exposed tubules by thermocoagulation, thereby achieving the goal of desensitization and cure.

2. Fluoride There are many forms of fluoride that can be used to treat dentine hypersensitivity. Fluoride ions reduce the diameter of the dentinal tubules, thereby reducing hydraulic transmission. In vitro experiments have also proved that: acidified sodium fluoride solution or 2% neutral sodium fluoride solution can reduce the hydraulic conductivity by 24.5% and 17.9% respectively; the hydraulic conductivity reduced by the sodium fluoride solution iontophoresis method is as high as 33% .

(1) 0.76% sodium monofluorophosphate gel (pH = 6) can maintain the effective fluorine concentration, which is the best effect in the current fluoride.

(2) Repeatedly rub the sensitive area with 75% sodium fluoride glycerol for 1 to 2 minutes; you can also use the orange wood tip to dip the medicine to rub the affected area for 1 to 2 minutes.

(3) 2% sodium fluoride liquid iontophoresis method

Use a DC electrotherapy device: the positive electrode is held in the patient's hand, the negative electrode is moistened with sodium fluoride solution, contacts the allergic area, the current intensity is 0.5 to 1 mA, and the patient has no discomfort as the limit.

Introduction of drug ions to electrolytic toothbrush: Install a dry battery (1.5V) at the end of the toothbrush handle. The brush handle is the anode (handle the handle) and the brush end is the cathode for drug penetration. Use this toothbrush to brush your teeth 2 to 3 times a day for 3 to 5 minutes each time. You should always check whether the current path is normal and whether the battery is exhausted. 3. Strontium chloride is a neutral salt. Highly water soluble and very low toxicity. Put into toothpaste for convenience and safety. 10% strontium chloride toothpaste is widely used abroad, and there are products in China. For topical rubbing, use 75% strontium chloride glycerol or 25% strontium chloride solution. Among the various drugs that have been extensively studied, strontium has shown strong adsorption to all calcified tissues, including dentin. The effect of strontium on dentin hypersensitivity is thought to be caused by the blocked dentinal tubules in the form of strontium apatite.

4. Wet the ammonia silver nitrate, dry the allergic area, apply the ammonia silver nitrate solution, and then reduce with clove oil until it is black. The protein silver and reduced silver produced after reduction can be isolated from conduction in the dentinal tubules. When applying, pay attention to the protection of oral soft tissues and avoid burns.

5. After silver iodide is coated with 3% iodine for 0.5 minutes, rub it with 10% to 30% silver nitrate solution. It can be seen that the off-white precipitate is attached to the allergic area. After 0.5 minutes, rub it once or twice again and it will work. This is to use silver nitrate to solidify the protein in the hard tissue of the tooth to form a protective layer. The effect of iodine tincture and silver nitrate produces new silver iodide deposited in the dentin tubules, thereby blocking conduction.

6. The electrocoagulation method is used to isolate moisture. Wipe the allergic point with a small cotton ball dipped in 10% formalin solution, electrocoagulate with a ball electrode for 1 second, and replace the cotton ball of formalin solution with an interval of 5 seconds. The coagulation time does not exceed 1 second, and the interval time is not less than 5 seconds. Each visit was performed 10 to 15 times. Formaldehyde in formaldehyde solution has a good diffusion effect, especially at high temperatures, the formalin solution releases formaldehyde to fix organic matter more effectively.

7. Other drugs 4% magnesium sulfate solution, 5% potassium nitrate solution, 30% potassium oxalate solution can be used for the treatment of dentine allergy.

8. Remedial therapy is not effective for repeated drug desensitization, and can be considered for filling or artificial crown repair. Individuals who are severely abraded and close to the pulp can consider treatment of pulp inactivation if necessary.

To prevent dentine allergies, you should brush your teeth properly and choose a qualified toothbrush. Use the correct brushing method to avoid excessive force when brushing your teeth. Reduce the intake of acidic foods and drinks. Do not brush your teeth immediately after eating acidic foods and drinks. Brush your teeth; if you already have sensitive teeth, you can replace ordinary toothpaste with a professional anti-allergy toothpaste. It soothes sensitivities while satisfying daily oral cleansing effects. In addition, the abrasive is good and the friction coefficient is low to prevent the tooth sensitivity from continuing to deteriorate. If there is no obvious effect after 4 ~ 8 weeks, you should seek medical treatment in time.

Allicin has antibacterial and anti-inflammatory effects, and has certain effects in treating dentin allergies. Raw walnut kernels contain a large amount of tannic acid, which can solidify the protein in the dentin tubules and can also desensitize.

Don't throw away the overnight tea at will. You can "use waste" and chew it in your mouth, especially allergic teeth. You can also directly chew fresh tea leaves into sensitive parts of your teeth. Studies have shown that tea is rich in fluorine and tea polyphenols. Tea polyphenols have disinfecting and sterilizing effects. It not only inhibits the growth of dental caries, but also enhances the acid resistance of tooth enamel. In the case, the antacid capacity is unexpectedly enhanced. In addition, the fluoride ion in tea also has very good health effects on the teeth. It has a great affinity with the calcium of the teeth, which is like adding a protective layer to the teeth.

1, tea teeth

Put the tea leaves directly into the mouth and chew them gently. It can fully absorb the rich fluorine and tea polyphenols in the tea leaves, which can alleviate the soreness and discomfort of the teeth, and has disinfection and sterilization effects. Especially fluorine has an excellent effect on preventing dental caries.

2. Chewing walnuts for desensitization

If tooth sensitivity has occurred, chew some walnut kernels before meals. The oily and acidic substances can penetrate into the dentin tubules, alleviate the sensitivity of the dentin, and play a certain desensitization effect.
