“Today, I get to buy a new toothbrush. I’m so excited,” said no one ever.

Sure, shopping for a toothbrush isn’t as fun as buying a new color of lipstick or clothing. It doesn’t even come close, but it is important. Replacing your toothbrush will help keep you and your family healthy and smiling. Here are some toothbrush tidbits that are good to know.

Toothbrushes Get Old and Frayed

According to the ADA, you should change your toothbrush at least every three to four months. When you think about it, that makes a lot of sense. After all, you use your toothbrush multiple times (hopefully) every day. And if you’re brushing correctly, the bristles are getting worn out. Regardless of how long you’ve had your current toothbrush if you see wear and tear on the bristles, replace it.

Replace Your Toothbrush After an Illness

If you’ve been ill, get a new toothbrush, or you could get sick again. If you have any type of virus, such as a cold sore, you should throw your toothbrush away. Please do not put it in the dishwater, microwave, or use disinfectants to get rid of the germs. Replacing your toothbrush may be a way to help you stay healthy.

Fun Toothbrushes Entice Children to Clean Their Teeth

Replacing their toothbrushes more often may make them take better care of their teeth. Colorful toothbrushes and ones with popular characters can get them to want to brush. Take them shopping to pick out the perfect one. Toothbrushes can also be birthday party favors, Halloween treats, and stocking stuffers. Make dental hygiene fun for your kids.

Get a New Toothbrush to Help With Dental Concerns

Maybe your gums bleed because you have gingivitis, or you have a higher cavity rate and need a toothbrush that will reach your back molars, or you have bad breath and need to brush your tongue with a toothbrush with a tongue cleaner. Whatever the reason, the type of toothbrush you choose can make a positive difference.

Take care of your teeth by replacing your toothbrush. Do it at least every three to four months, after you’ve been sick if your current toothbrush looks worn out or you’re having dental problems. After all, your teeth do a lot for you. They smile. They chew. Then, they smile and chew some more. If you have kids, find one that they’ll want to use. Toothbrushes come in all shapes and sizes. Make sure to look for the ones that are recognized by the American Dental Association (ADA). Most dental professionals agree that a soft-bristled brush that is gentle on the gums is best. Happy toothbrush shopping.
