Your toothbrush is your all-important first line of defense against tooth decay and gum disease, but these appliances are not designed to last forever. Using the same brush for too long can diminish its ability to properly clean your teeth and expose you to harmful bacteria. Here’s a brief guide to why it’s important to change your toothbrush every three months or so and a few signs that your appliance is ready to be replaced early.
Why Should I Replace My Toothbrush Every Three Months?
Even if you keep your toothbrush perfectly clean, it’s still best to replace it every three months. This is because the bristles will become frayed due to the wear and tear caused by daily use as well as how bacteria and food residue can accumulate on the brush. Brushing with worn bristles can make it more difficult to thoroughly clean your teeth, and it is possible to contract infections from an unsanitary dental appliance.
Do I Ever Need to Replace My Toothbrush Before Three Months?
It is necessary to replace a toothbrush before three months have passed if it:
- has bristles that are excessively frayed
- has visible accumulations of food particles that do not respond to rinsing
- has been in a wet, enclosed space for an extended period
- was used while you were ill
- was used by another person
How Can I Pick the Best Toothbrush to Replace My Old One?
There are many toothbrush brands available at grocery stores and pharmacies, and the one that is best for you depends largely on your preferences of size, grip, shape, and color. However, dentists recommend choosing toothbrushes based on the following criteria:
- Soft bristles: Brushing with stiff bristles can scratch your enamel and erode your gum tissue. It’s best to choose an appliance with soft bristles that are gentle on your oral tissues.
- Electric is better: Dentists recommend using an electric toothbrush to achieve a superior clean, and these devices can be especially excellent for those who have conditions that make it difficult to brush their teeth such as arthritis. Many people also find the vibrating sensation electric toothbrushes cause in their teeth to be quite pleasant. However, a manual toothbrush is still a perfectly suitable option.
Don’t let an old toothbrush hinder your oral hygiene efforts. Replacing your appliance as recommended will help you keep your teeth clean, healthy, and beautiful.
