Believe it or not, your toothbrush may be one of the dirtiest things in the bathroom. The average toothbrush has thousands, sometimes millions, of living microorganisms dwelling within their bristles, which is why it’s so important that you change your toothbrush often. So just how often should you replace your toothbrush? If you are like every other person on the planet, it’s recommended that you change your toothbrush or toothbrush head if you’re using an electric toothbrush every three months. If you have an immune deficiency or you have been sick you may want to consider changing your toothbrush more often, perhaps every six weeks. There are several tips to remember when to change your toothbrush, but one of the easiest is to change it with every new season of the year: spring, summer, fall, and winter. Caring for your toothbrush is very important because it’s the primary tool you will be using to keep your teeth and gums healthy and looking good. It’s important that you use your toothbrush correctly and after each use you want to make sure to rinse it our thoroughly using tap water and then let it air dry. You want to always store your toothbrush in an upright position. Normally you don’t have to worry about storing your toothbrush next to other toothbrushes because bacteria will usually not be able to travel from one toothbrush to the other without them actually touching. However, you may want to make sure that you have a cap or cover for your toothbrush to ensure that no airborne particles are able to travel onto your toothbrush when you’re not using it.
