How Often Should I Really Replace My Toothbrush?


We are aware that toothbrushes aren’t supposed to last a lifetime, yet, when was the last time you changed your toothbrush? It can be difficult to figure out when the bristles have been worn out and when it’s time for a replacement.

According to toothbrush manufacturers and dentist, a toothbrush must be replaced every twelve to sixteen weeks. In certain cases you might need to replace it sooner, for example if you’ve recently recovered from a tooth infection. Failure to replace the toothbrush will spread the infection.

How often to toothbrushes need to be replaced?

The toothbrush you use is your first line of defense against bacteria that leads to periodontal disease, tooth decay, and halitosis.

If you regularly brush your teeth twice a day, you’re maintaining good oral hygiene. That does, however, also mean that your toothbrush will wear out too. The bristles wear out and lose their stiffness, making it less effective. Toothbrushes uses regularly begin to lose bristles or the bristles become twisted in around 3 months. Your dental hygiene won’t be up to the mark if you use such a toothbrush. The bristles won’t be firm enough to remove bacteria and plaque. It also won’t reach all the corners of your mouth too.

The centers for disease prevention and control (cdc) advises people to replace their toothbrushes every 3 to 4 months for optimal dental hygiene.

What about an electric toothbrush head?

Electric toothbrushes are more expensive, but they are built to improve your dental hygiene. Certain brands of electric toothbrushes come with apps that help you monitor how well you’re brushing your teeth and areas you need to focus on more. Their vibrating bristles also improve the effectiveness of the toothbrush as well.

Electric toothbrush heads have nylon bristles that also wear out with regular use. Electric toothbrushes also have shorter bristles, making them prone to fraying quicker. Make sure you change the electric toothbrush head every 12 weeks. Keep an eye out for signs of wear and tear, in case they begin to wear out sooner.

Other reasons to change a toothbrush

If you or a member of the family has been ill recently, it’s best to replace all the toothbrushes in the home. Bacterial and viral infections like strep throat, in particular can spread due to toothbrushes. As for children, change theirs more often as they are likely to chew on the bristles or handle of the toothbrush.
