How long has it been since I changed my toothbrush? Probably many people's answer is, "It's been a long time." Kevin Sands, a dental doctor in Beverly Hills, California, believes that under normal use, a new toothbrush should be replaced every three or four months, with the purpose of maintaining the "brushing" strength of the bristles and avoiding too much bacterial accumulation.
The American Dental Medicine Association also recommends that you should change a new toothbrush as long as the bristles are tied into groups or worn.
The virus season is coming, and it should also be considered whether it has been sick recently. Sanz said, "After being sick, it is best to change clean and new toothbrushes to prevent bacteria from staying for a long time."
How to "maintain" the toothbrush to keep it in the best condition before changing it? Both Sanz and the American Dental Medical Association recommend that you wash the toothbrush first after brushing your teeth. He said, "For most people, it will be enough to wash it with hot water. Heat water has the effects of softening bristles, cleaning toothpaste, and removing food crushed powder."
After washing and cleaning, how to place it is also important. Sanz said, "Toothbrushes are easy to breed bacteria, so it is important to put them in a clean, dry place." That is to say, you cannot hold it or cover it to avoid tying the bacteria in the bristles. After blowing, it is of course easier to "keep dry."
California dental doctor Kami Hoss said, "Bacteria likes damp and dark places. Putting a toothbrush on is to create a damp and dark environment," so that bacteria can grow easily.
When traveling, it is normal to put the toothbrush into the toilet box and then put it in the suitcase, so that the toothbrush can be kept clean. However, when you arrive at the room, remember to open it and dry it, and dry it after each use.
The Center for Disease Control and Prevention also reminds the public that if you share the room and bathroom with others, it is best to put the toothbrushes in one place and do not contact them to avoid bacterial dissipation and infection. "Even if it is to be placed in the same toothbrush drum, don't touch two toothbrushes."
