Tooth remineralization is the natural repair process for non-cavitated tooth lesions, [1] [2] in which calcium, phosphate and sometimes fluoride ions are deposited into crystal voids in demineralised enamel. Remineralization can contribute towards restoring strength and function within tooth structure.
Tooth enamel can become demineralised due to various factors, including acidic erosion and dental caries. If left untreated this can lead to the exposure of dentin and subsequent exposure of the dental pulp. In various studies the use of nano hydroxyapatite in toothpaste showed positive results in aiding the remineralisation of dental enamel. [32]
However, a tooth whitening product with an overall low pH can put enamel at risk for decay or destruction by demineralization. Consequently, care should be taken and risk evaluated when choosing a product which is very acidic. [46] Tooth whiteners in toothpastes work through a mechanical action.
Tooth decay, also known as cavities or caries, [a] is the breakdown of teeth due to acids produced by bacteria. [6] The cavities may be a number of different colors, from yellow to black. [1] Symptoms may include pain and difficulty eating.
The fluoride ions reduce the rate of tooth enamel demineralization and increase the rate of remineralization of teeth at the early stages of cavities. Fluoride exerts these effects by the demineralization and remineralization cycle. [23] The remineralization cycle, critical to decay prevention, occurs when fluoride is present in the oral cavity.
In this creamy radish soup recipe, radishes are sautéed and pureed with potato, creating a velvety, healthy soup. Cooking radishes also tones down any bitterness while leaving plenty of sweet ...
Warner Bros. Discovery, CNN’s corporate parent, announced Thursday it is establishing a new corporate structure that splits off its cable networks from its growing streaming business.
If permanent restoration cannot be carried out immediately after tooth preparation, temporary restoration may be performed. The prepared tooth, ready for placement of restorative materials, is generally called a tooth preparation. Materials used may be gold, amalgam, dental composites, glass ionomer cement, or porcelain, among others.
