When to change your toothbrush

Most of us are aware that our toothbrushes are not designed to last indefinitely. However, determining whether our beloved bristles are approaching the end of their natural life cycle can be difficult.

You may be startled to learn that your toothbrush should be replaced every 12 to 16 weeks, according to manufacturer guidelines and dentist recommendations. In some instances, you may need to replace your toothbrush sooner than expected. It can harm your dental health and spread infection if you don’t replace your toothbrush or electronic toothbrush head when it’s time.

How often should you change your toothbrush?

Gum disease, tooth decay, and bad breath are all caused by bacteria, and your toothbrush is your first line of protection against them.

The easiest way to navigate the smallest crevices in your mouth is with straight bristles and a clean, easy-to-grip handle. A soft bristle brush will easily remove any old food or bacteria that may have accumulated around the bases of your teeth.

Brushing your teeth for two minutes twice a day, as recommended by the American Dental Association, is already protecting your teeth from cavities.

If you follow the standard recommendation of brushing your teeth for 2 minutes twice per day, you’re already taking steps to protect your teeth from cavities. Brushing your teeth after each meal and after a sugary snack is another proactive measure you may take to avoid tooth decay.

Brushing two or more times each day with a manual toothbrush is still considered conventional. Within 3 months of using your brush at this rate, the bristles will begin to fall out and get damaged or twisted.

The Center for Disease Control and Prevention (CDC) also recommends replacing your toothbrush every three to four months.

How often should you change an electric toothbrush head?

To clean the surface area of your teeth, electric toothbrush heads rotate or vibrate quickly. With prolonged use, the nylon bristles on these toothbrush heads may wear out. Furthermore, the bristles are more likely to fray since they are shorter.

Other reasons to change your toothbrush

Virus and bacteria-based infections, such as strep throat, are particularly harmful and require replacing your old toothbrush.

Since kids may pound the head or chew on the handle, children’s toothbrushes should be replaced more frequently than every three months.

Keep a eye on your kids as they brush their teeth to be sure they aren’t brushing anything other than their teeth with their brush head. Get rid of your toothbrush if someone else uses it by accident. It’s better to be safe than sorry, because everyone’s mouth contains bacteria that are different from yours.

Risk factors for using a toothbrush beyond its recommended lifespan

The nylon bristles of your toothbrush are exposed to water and chemicals from your toothpaste every time you brush. With each use, the bristles become a little weaker. “Bristle flaring” develops when the bristles bend and twist into a new shape.

According to a study, bristle flaring begins to make your toothbrush less effective after 40 years of continuous use. Participants in the study who did not change their toothbrushes by the 40th day of use had significantly greater plaque buildup.

In least two previous research on worn toothbrush heads found that older toothbrushes are ineffective at eliminating plaque, the leading cause of gum disease and tooth decay.
