What are the ingredients in a good toothpaste?

For me, a good toothpaste should have herbs and fluoride that repels cavities and strengthens teeth.

I would choose a toothpaste that whitens my teeth because it gives me the courage to smile with confidence.

I would definitely choose a toothpaste that the whole family can use.

I chose to use fluoride toothpaste.

The principles for selecting toothpaste ingredients are as follows:

Choose the right toothpaste according to the condition of your teeth. If your teeth are yellow, choose one that contains "silicone"; For those with tooth sensitivity, choose "strontium chloride" or "potassium nitrate"; To prevent tooth decay, select those that contain "fluorine"; To prevent tartar, choose one that contains "pyrophosphate" or "zinc citrate".

Looking at the color ** at the bottom of the toothpaste, we can take a look at the toothpaste we use has a short color line at the bottom, which is divided into 4 colors (green, blue, red, black), and these colors ** represent different meanings: green: pure natural ingredients; Blue:

Natural + Pharmaceutical Ingredients; Red: Natural + Chemical; Black: Pure chemical composition.

Types of toothpaste

Chinese herbal toothpaste: It is a combination of some Chinese herbs added to the ordinary toothpaste.

Anti-inflammatory drug toothpaste: add certain antibacterial drugs, such as chlorhexidine, to the ordinary toothpaste.

Anti-allergic toothpaste: add jujube desensitizing ingredients to the toothpaste, such as fluoride and strontium chloride, but only mild dentin allergy can play a certain alleviating role, if it is still ineffective after using it for a period of time, it should be stopped, and it is best to seek help from a professional doctor in the hospital and use other desensitization methods.

Descaling and whitening toothpaste: This kind of toothpaste contains drugs such as peroxide source rock preparation or hydroxyapatite, which can use the principle of friction and chemical bleaching to remove the coloration of the tooth surface, and play a role in whitening the teeth and removing the exogenous coloration of the tooth surface. However, if the friction particles in the toothpaste are large and hard, long-term use and brushing too hard may lead to tooth wear.

Summary. Wetting agents, surfactants, friction agents.

Wetting agents, surfactants, friction agents.

1. The wetting agent contained in the toothpaste can avoid the drying and hardening of the paste, especially the induration of the toothpaste nozzle that is not easy to extrude, and can keep the appearance of the paste bright. In addition, the humectant can also reduce the freezing point of the paste, so that the toothpaste can be used normally even in cold areas. Wetting agents have a great impact on the colloidal parts of toothpaste, and as long as you know the right amount of application, you can maintain its stability.

2. The surfactant contained in the surfactant toothpaste can reduce the surface tension, penetrate and loosen the dirt on the surface of the teeth, and make the dirt become emulsified or suspended, which is easy to be brushed off by toothbrushes and friction agents, and then spit out with mouthwash. The reason why foaming occurs when brushing teeth is that surfactants work to help clean the tooth surface. In addition, surfactants can also have a slight sterilizing effect and have good compatibility with friction agents, but excessive use of surfactants will reduce the aroma of toothpaste.

3. The ingredient that contains the most jujube in friction toothpaste is friction agent, which will account for 25% to 60%. Friction agents can enhance the friction effect of toothpaste, enhance its decontamination ability, and also polish the tooth surface. However, there are also great requirements for friction agents, first of all, to ensure that there is friction, second, to avoid damage to periodontal tissues and tooth surfaces, and thirdly, not to have a chemical reaction with the drug in toothpaste.

In particular, the friction agent of fluoride toothpaste must be compatible with fluoride ions in order to maintain the activity of fluoride ions. Generally, the finer the fineness of the friction agent, the smaller the shape of the granulator, and the better the quality of the toothpaste.
