Your toothbrush is your primary weapon against the bacteria that cause tooth decay and gum disease, but it will wear down and accumulate unpleasant residues with age. Continuing to clean your teeth with an older toothbrush can lead to inadequate results and expose your mouth to infectious germs. Here’s a guide to why you should change your brush regularly as well as a few tips for choosing the best replacement.
I Like My Old Toothbrush; Why Do I Have to Replace It?
The American Dental Association recommends replacing your toothbrush every three months. Regular use will wear down the bristles and cause some of them to fall out, which can diminish the appliance’s ability to gently scrub plaque and food residue away from the teeth. This may force you to press harder when brushing, which can scratch your enamel. To make matters worse, accumulations of old toothpaste and food particles on your appliance can provide a damp and nutritious breeding ground for harmful bacteria.
It’s also best to replace your toothbrush immediately if anybody but you has used it or if you or anyone in your household has been sick to help prevent the spread of germs.
What Should I Look for When Shopping for a New Toothbrush?
Toothbrushes are commonly sold at grocery stores and pharmacies, and you will probably find a wide variety of brands to choose from. It’s best to choose a toothbrush with soft bristles, as this will make it gentler on your enamel and less likely to injure your gums. While a manual toothbrush will be sufficient, dentists recommend using an electric toothbrush to achieve a superior clean. Electric toothbrushes are also great options for those who have dexterity issues like arthritis.
How Can I Keep My Toothbrush Clean?
Storing your toothbrush properly is the best way to prevent bacterial growth. It’s best to follow these guidelines:
- Use a toothbrush holder to keep your appliance in an upright position when not in use. This will help it dry out faster, which makes it more difficult for germs to multiply.
- Keep your toothbrush out in the open so it is exposed to the most light and airflow possible. Storing it in a cabinet will create the dark, damp sort of environment that bacteria need to thrive.
- After using your toothbrush while traveling, allow it to dry out for an hour before packing it. It’s also best to unpack it as soon as possible when you reach your destination.
Don’t let an old toothbrush hinder your hygiene efforts and expose you to nasty bacteria. Replacing your appliance regularly will help you stay in great oral health.
