How Often Should You Replace Your Toothbrush?

Toothbrush with toothpaste

When was the last time you replaced your toothbrush? It probably has been a while, and the bristles have started to wear off.

It is a normal routine for us to regularly replace and restock our vitamins, supplements, beauty products, etc. However, when it comes to our toothbrushes, we become a little negligent.

When To Change Your Toothbrush?

The general recommendation by the American Dental Association (ADA) is to change your toothbrush every three months. Over time, the toothbrush goes through a lot of wear and tear, making it less effective in removing plaque and other germs from the teeth and gums. Some studies show that the bristles breakdown and lose their effectiveness after being used for about three months.

Another factor that most people don’t think about is that germs and hide and build up in the bristles. So if you just had a cold or some other infection, you should replace your toothbrush soon afterward to prevent recontamination, irrespective of how long you’ve been using it.

What if You Don’t Replace Your Toothbrush in a Timely Manner

Aside from germs and bacteria building up in the bristles, various other risks come into play if you continue using a toothbrush past the three-month mark. However, this practice can lead you to become sick as the bacteria will eventually attack you.

Another significant risk is the development of gum disease. Since old toothbrushes don’t remove plaque effectively, it can lead to the development of gingivitis. If left untreated, gingivitis can result in your teeth falling out.

Hence, it is essential to replace your toothbrush on time. If you notice that the bristles on your toothbrush are starting to break, then you should replace it immediately, even if you have not used it for three months.
