Description

Toothpaste for relieving dentin sensitivity

Technical Field

The invention relates to the technical field of toothpaste, in particular to toothpaste for relieving dentin sensitivity.

Background

Tooth sensitivity is commonly called as "tooth inversion", also known as dentine hypersensitivity or tooth root sensitivity, and refers to the symptoms of abnormal acidity, softness and pain of teeth when the teeth are subjected to external stimuli such as temperature, chemistry, machinery and the like. Dentinal hypersensitivity occurs in connection with the flow of open dentinal tubules and irritation and inflammation of the pulp or tubule nerves or cytoplasm. The long-term trouble of tooth sensitivity affects the daily life quality of people.

At present, some patients close dentinal tubules by means of operation to block external stimulation, but some patients tend to use simple and convenient methods, such as tooth brushing, mouth rinsing, smearing and the like, to effectively relieve sensitive symptoms of teeth. Wherein, the application of the toothpaste is the simplest and most convenient, and the toothpaste is most in line with economic benefits.

Disclosure of Invention

The invention aims to provide toothpaste for relieving dentin sensitivity, which is scientific and safe, and can effectively relieve the tooth sensitivity and repair teeth.

In order to achieve the purpose, the invention provides toothpaste for relieving dentin sensitivity, which comprises an abrasive, a humectant, a thickening agent, a foaming agent, a sweetening agent, essence, a preservative and water, and also comprises 8-16% of an anti-sensitivity component, wherein the anti-sensitivity component comprises 16-28% of paeonol, 31-56% of clove oil, 11-16% of hydroxyapatite and 17-26% of potassium citrate.

Preferably, the anti-allergic ingredient comprises 17% paeonol, 48% clove oil, 14% hydroxyapatite and 21% potassium citrate.

Preferably, the anti-allergic ingredient comprises 21% paeonol, 50% clove oil, 11% hydroxyapatite and 18% potassium citrate.

Preferably, the anti-allergic ingredient comprises 28% paeonol, 32% clove oil, 16% hydroxyapatite and 24% potassium citrate.

A preparation method of toothpaste for relieving dentin sensitivity comprises the following steps:

s1, putting the weighed thickener, clove oil and paeonol into a powder bin together, and uniformly stirring to form an oily solution;

s2, putting the weighed sweetener, the preservative, the potassium citrate and the hydroxyapatite into a premixing tank, adding the humectant and the water, fully dissolving, and sucking into a paste making machine;

s3, sucking the solution prepared in the step S1 into a paste making machine, and quickly stirring the solution until the solution is uniform;

s4, sucking the foaming agent and the abrasive into a paste making machine, and quickly stirring the mixture until the mixture is uniform after the powder is fed;

s5, slowly sucking essence, rapidly stirring under vacuum to uniform, mixing for 16-21min, degassing, standing, filtering, and sterilizing to obtain toothpaste.

Therefore, the toothpaste for relieving dentin hypersensitivity is scientific and safe, and can effectively relieve the dentin hypersensitivity and repair teeth. Cortex moutan extract acts on dentin nerve endings to relieve pain; clove oil is antiseptic, antibacterial and analgesic, and can be used for preventing oral diseases and inflammation. Meanwhile, potassium ions in the potassium citrate act on nerve endings of dentinal tubules after being released, the repolarization of nerve fibers is inhibited, the excitability of the nerve fibers is reduced, the conduction of nerve cells to pain signals is interfered, the sensitivity of teeth is relieved, meanwhile, the calcification degree of dentin is obviously improved, the formation of reparative dentin is promoted, and potassium salt crystals block the dentinal tubules to isolate external stimulation. In addition, the hydroxyapatite closes dentinal tubules, relieves the sensitivity of teeth to cold, heat, acid and sweet caused by nerve stimulation, relieves or even disappears the tooth sensitivity symptom, and can fundamentally prevent and relieve the oral problems of tooth sensitivity, antibiosis, antiphlogosis and the like.

The technical solution of the present invention is further described in detail by the following examples.
