Treatment of tooth sensitivity is a common problem in oral medicine, and tooth sensitivity may be an early signal of oral diseases, such as dental caries and gum receding. By treating sensitive teeth, dentists can detect and deal with these potential problems in time to prevent further development of the disease.

Causes and hazards of tooth sensitivity

The main causes of tooth sensitivity are enamel wear, gum atrophy, etc., resulting in exposure of dentin tubules, and external stimuli transmitted to the pulp through the tubules, causing pain. If the tooth sensitivity is not treated in time, it may lead to more serious oral problems such as pulpitis and periapical inflammation.

Definition and characteristics of tooth sensitivity

Tooth sensitivity is not an independent disease, but a common symptom of a variety of dental diseases, such as dental cleft, wedge defect, tooth enamel wear, alveolar bone atrophy and other oral diseases, there will be clinical symptoms of tooth sensitivity. Tooth sensitivity (generalized) - refers to the exposure of dentin by external stimuli (mechanical, chemical, temperature, osmotic pressure, etc.) caused by a specific pain symptoms.

Treatment of sensitive teeth

•Physical methods to close or block the outer end of the dentin tubule

•The protoplasm of dentin tubule was coagulated by chemical method

•The chemicals react with tooth tissue to form deposits that clog the tubules

•Induce dentin formation and close the proximal pulp end of dentin tubules

•The anesthetic properties penetrate into the pulp through the tubules and block the pulp nerve endings

•Some substances penetrate into the pulp through the dentin tubules and inhibit the stimulation of the pulp nerve

To sum up the above six points there are two points:

•Change the permeability of dentin tubules

•Reduce the excitability of pulp nerve

It is suitable for relieving the symptoms of tooth sensitivity caused by dentin exposure

The desensitizing agent can quickly penetrate into and block the dentin tubules and produce calcium oxalate crystals. At the same time, the crystal precipitates release potassium ions to depolarize the dental pulp nerve cells, which is mild and does not stimulate, and plays a rapid and long-term dual desensitization role.

Applicable location area: For direct and indirect restoration, sensitive areas of teeth, especially the most common wedge fracture of the neck, as well as the severe wear area of the back teeth, such as severe wear or severe night molars, need to increase the application frequency. It can also be used to seal the dentin immediately after the preparation of the tooth system.

Mechanism of dental desensitizers

There are two main mechanisms of action of dental desensitizers:

•Occluding dentin tubules: Active ingredients penetrate into tubules, form coagulants with proteins, deposit and block tubules, blocking external stimulation.

•Reduce the sensitivity of pulp nerve: By increasing the extracellular potassium concentration of nerve endings, it is depolarized and reduces excitability.

Advantages of dental desensitizers

•Rapid relief of sensitive symptoms: After use, it can quickly reduce or eliminate the sensitive reaction of teeth to cold and hot, sour and sweet stimuli.

•Long-term protection: The protective layer formed can last for a long time, effectively preventing external stimuli from triggering sensitivity again.

•Safety and no side effects: generally composed of natural ingredients, no irritation to oral tissue, safe and reliable use.

•Stable performance: it does not affect the structural and sealing effect of subsequent treatment filling materials.

How to use:

1.Clean the desensitized surface of teeth, then rinse with water and dry;

2.Use rubber barrier or cotton roll to fully isolate teeth from moisture;

3.Apply a little desensitization agent with a brush evenly on the tooth surface with allergic symptoms, and then keep it for 30 to 60 seconds;

4.desensitization effect, the desensitization agent is evenly infiltrated into the dentin tubule by gently blowing with a non-oil-gas gun.
