Is alkaline toothpaste effective in whitening?

Toothpaste is a daily cleaning product, and it is a must-have. So do you know whether toothpaste is acidic or alkaline? Does toothpaste have the effect of whitening teeth?

Is toothpaste alkaline?

Toothpaste is basically weakly alkaline. The main ingredients of toothpaste are calcium carbonate and sodium ions, which can play a cleaning role. It is alkaline substances, not acidic substances, that can play a cleaning role. The decayed substances in the mouth are weakly acidic, and the weak alkalinity of toothpaste can neutralize and clean them. Toothpaste is a kind of tooth cleaning product, generally in gel form, and is usually applied to a toothbrush. With the help of the mechanical friction of the toothbrush, it cleans the surface of the teeth, cleans the teeth and their surroundings, and purifies and refreshes the mouth.

Does toothpaste have a whitening effect?

The effect of whitening toothpaste on whitening teeth is minimal, and there is almost no whitening effect. One type of whitening toothpaste currently used is added with a relatively rough abrasive, and the other is added with peroxide. The cleaning principle of the former type of whitening toothpaste is the same as that of ordinary toothpaste, except that the friction particles are large, and the friction generated with the tooth surface when brushing teeth will be relatively large, which can achieve the purpose of removing some pigments and dental plaque. However, long-term use will make the teeth rough and uneven, causing the accumulation of pigments and plaque, leading to tooth discoloration. The peroxide added to the second type of whitening toothpaste will react chemically on the surface of the teeth, which can then play a role in chemical whitening. However, the peroxide content in general toothpaste is relatively low, and the whitening effect produced is also minimal.

Can adding salt to toothpaste whiten teeth?

Toothpaste with salt can whiten teeth. The main component of table salt is sodium chloride, and the chloride ions and sodium ions in it both have a certain whitening effect. In addition, toothpaste itself can remove oral dirt, so brushing your teeth with toothpaste and salt can whiten teeth. However, the effect of toothpaste and salt on whitening teeth is not very good. On the one hand, the toothpaste and salt used each time are only a small amount, and the whitening ingredients are small and the effect is weak. On the other hand, there are many reasons for tooth discoloration, and brushing your teeth with toothpaste and salt can only have a clearing and whitening effect on pigment deposits such as coffee and beverages.

How to add salt to toothpaste when brushing your teeth
