Does toothpaste need to be changed frequently

Toothbrushes need to be replaced frequently, and so does toothpaste. Sometimes, using the same toothpaste for a long time is like making the bacteria in your teeth resistant. If you find a toothpaste that tastes good and works well, use it regularly. But if the effect is average, you can consider changing toothpaste. When brushing your teeth, you can add a little salt to the toothpaste to make your teeth whiter.

3 In addition, if your teeth are prone to tooth decay, you can choose a toothpaste containing fluoride. The main ingredients in toothpaste are similar, because toothpaste mainly plays a cleaning role, but different toothpastes will add different auxiliary ingredients, and human teeth may have different conditions at different times, so you should choose the appropriate toothpaste according to the specific condition of your teeth.

But there is one thing that everyone needs to pay attention to, that is, don’t choose particularly expensive toothpaste. When we go to the supermarket, we will find that some toothpastes are very expensive. Maybe 40 grams of toothpaste will cost 70 or 80 yuan. In fact, the main function of these toothpastes is cleaning, and they do not have the magical effects advertised, so it is recommended that you do not buy particularly expensive toothpastes.
