In the following dental topics, in this article we discuss the characteristics of a suitable toothpaste.
What is the most important feature of a standard toothpaste?
If you are looking to buy the best toothpaste, you should look for options that contain fluoride that prevent tooth decay. All standard toothpaste contains fluoride.
Importance of fluoride in toothpaste:
Fluoride is naturally present in the body in the form of calcium fluoride. It is mostly found in bones and teeth. Water, some drinks and some foods such as seafood also contain fluoride.
Fluoride reduces tooth decay by affecting the development of the tooth cells that are responsible for the final shape of the tooth. After tooth eruption, if the tooth is exposed to fluoride-containing fluids (foods and saliva), fluoride uptake continues on the enamel surface. In addition to its protective effect on the enamel, fluoride can also reduce the decay process by affecting the process of bacterial attack on the tooth. This process occurs in two ways: by reducing the metabolism of bacteria to produce acid and by reducing the acidic state of the saliva (increasing the pH of the saliva).
Toothpaste fluoride content:
Appropriate fluoride toothpastes contain 1300 ppm to 1500 ppm fluoride (ppm is a measure of particulate matter concentration in solutions). Fluoride levels in children’s toothpaste are lower than this, because excessive ingestion of fluoride can lead to child poisoning and sometimes cause unpleasant white spots on the teeth called fluorosis. Therefore, adult toothpaste (containing more fluoride) is not recommended for children 6 years and younger who have less control over their swallowing.
Is Fluoride, one of the constituents of toothpaste today, harmful to human health?
American health and scientific organizations, based on a review of articles and studies on large human groups, all believe that there is no basis for claiming fluoride is a cause of cancer or other diseases.
Toothpaste for sensitive teeth:
These toothpaste contains potassium nitrate, strontium chloride and strontium acetate. These substances greatly reduce the pain of sensitive teeth by deposition on dentinal tubules and blocking the nerve terminals within them.
The thing to note is that most of these toothpastes do not produce much foam when used, but the absence of too much foam is not a sign of a bad toothpaste.
Importance of using fluoride toothpaste during pregnancy:
As we said, fluoride is one of the important factors in strengthening bones and teeth. During pregnancy, some pregnant women have persistent vomiting, and prolonged exposure to gastric acid during this period exposes their teeth to decay so that even gastric acid may dissolve enamel. Therefore, experts recommend that pregnant women use fluoride-containing toothpastes during pregnancy to reduce the risk of tooth decay.
Whitening toothpaste removes stains on the outer surfaces of teeth caused by drinking tea and coffee, smoking as well as other causes. These toothpastes contain whitening agents such as oxygen peroxide or small abrasive particles that form enamel. Thus the outer layer of the tooth is removed and the lower layer appears whiter. But if the toothpaste is used excessively, the luster and tooth enamel will be lost, and the lack of enamel will eventually lead to decay. Therefore, this type of product is not recommended for daily and long-term use.
These toothpaste contain carbon. Carbon due to its abrasive properties can damage the enamel. Charcoal toothpaste or tooth whitening have abrasive and abrasive properties that can cause tooth decay and decay in a short period of time. This type of toothpaste has low fluoride content and does not protect the teeth completely. Although charcoal toothpaste can partially remove tooth decay, it does not have much different effect than other toothpastes.
