In life there is always a group of people whose teeth will hurt in the summer if they eat ice cream, and if they eat something sour in the fall, even oranges will hurt their teeth.The toothpaste manufacturer reported that this is a group of people with extremely sensitive and fragile teeth who are very afraid of eating foods that irritate the senses, the most common of which are cold and sour foods.Under normal conditions, the integrity of tooth enamel is compromised, and various dental diseases, such as dentin exposure, such as abrasion, wedge-shaped defects, tooth fractures, caries, as well as exposure of the tooth neck due to periodontal atrophy, can cause tooth hypersensitivity..However, not all teeth with exposed dentin will have symptoms, this is usually related to the time of dentin exposure and the rate of formation of restorative dentin.Some teeth with intact enamel may also develop sensitivity.Soviet scientists called this disease “hypersensitivity of enamel and dentin,” or “tooth hypersensitivity” for short, which is more accurate.Most causes of tooth sensitivity are that the dentinal tubules on the surface of the tooth open for various reasons (trauma, development, chemical corrosion, etc.), so external hot and cold stimulation and chemical stimulation can strongly stimulate the pulp cavity.Dental nerve causes discomfort. Toothpaste manufacturing engineers have stated that there are two main mechanisms for desensitizing toothpaste: 1. Some toothpaste manufacturers use strontium acetate, which seals the dentinal tubules through components similar to the fine particles found in toothpaste, weakening or even preventing changes in fluid flow in the dentinal tubules, thereby relieving tooth sensitivity;2. There are also some toothpastes that use anti-sensitivity toothpastes containing potassium ion formulas that act through a depolarizing mechanism to interfere with the transmission of nerve signals, which means that the sensitivity of the dental nerve is reduced and sensitive stimulation cannot be felt.
