We need to understand the main ingredients and functions of toothpaste. Toothpaste is mainly composed of friction agent, moisturizing agent, surfactant, fluoride ion source, fragrance, etc., of which friction agent is one of the main components of toothpaste, which is used to remove dirt and plaque on the surface of teeth; Fluoride sources help prevent tooth decay. Therefore, choosing the right toothpaste for you is very important to maintain oral health.
Experts are not in agreement on the need to change toothpaste frequently. Some experts believe that changing the brand and type of toothpaste frequently can help prevent oral bacteria from developing resistance to the same toothpaste, thereby better protecting dental health. Other experts believe that frequent toothpaste changes can disrupt the balance of oral flora and be detrimental to oral health.
How do we choose?
First, we need to understand our oral health. If your teeth are in good health and you don't have obvious oral problems, it's okay to choose a toothpaste that suits you and use it for a long time. However, if you have oral problems, such as mouth sores, gingivitis, etc., you need to seek medical attention and consult your doctor for advice.
In addition, we also need to consider the composition and efficacy of the toothpaste. Different brands and types of toothpaste have different ingredients and benefits, for example, some toothpastes have anti-allergy properties, while others have a breath-freshening effect. Therefore, we need to choose the right toothpaste for ourselves according to our needs.
Finally, we need to focus on the shelf life of toothpaste. Generally speaking, the shelf life of toothpaste is about 3 years, and expired toothpaste is easy to breed bacteria, which not only cannot play a role in cleaning the mouth, but will cause harm to oral health. Therefore, we need to pay attention to the shelf life of toothpaste and replace it with a new one in time.
