When Should You Replace Your Toothbrush?

Most dentists and the American Dental Association (ADA) recommend replacing your toothbrush every 3 months. Overtime, toothbrushes go through normal wear and tear and become less effective at removing plaque from teeth and gums. Studies have found that it is about 3 months before the hairs deteriorate and lose their effectiveness.


Another thing we typically don't think about (and probably don't like to think about) is that germs can hide and accumulate on toothbrush bristles. This makes it important to replace your toothbrush after you catch a cold or risk possible re-infection.

Fungi and bacteria can also develop on the hairs if not taken care of properly. After use, be sure to rinse and dry your toothbrush thoroughly, store it upright, uncovered, and keep it away from other used toothbrushes. When traveling, be sure to cover the head of your toothbrush to protect it and reduce the spread of germs.

If you can't remember exactly how much time has passed, pay special attention to the condition of your toothbrush head – whether the bristles are worn, weathered or frayed, or you may notice dark discolorations that are a particularly sign.

What Happens If I Don't Change My Toothbrush Frequently Enough?

If knowing bacteria and fungus builds up on the bristles of your toothbrush overtime isn't reason enough to change your toothbrush more often, there are other risks and undesirable problems of not replacing your toothbrush. One risk includes damaging your gums, as old toothbrushes become ineffective at removing the plaque that causes gingivitis from your teeth. Untreated gingivitis leads to infection that can cause teeth to fall out.

Even more unattractive, you can get sick from overused toothbrushes, your toothbrush may become moldy, or, possibly the least attractive, pick up unwanted particles if you store them near the toilet.

What Should Be Considered While Buying Dental Products?

During your next dental checkup and cleaning, it will be tailored to your individual needs, specific dental health condition, etc. Consult your dentist for recommendations on what to buy.

Some common recommendations among dentists are to look for toothbrushes with soft bristles as hard bristles damage your teeth and gums, choose a toothbrush head that touches one or two teeth at a time, and use an ADA-approved fluoride-containing toothpaste. To further fight plaque and gingivitis, use mouthwash and don't forget flossing!

Consider investing in an electric toothbrush, as these are proven to improve oral health beyond what a manual toothbrush can do by removing plaque, reducing gingivitis and eliminating tooth stains. They have also been shown to minimize the amount of plaque on the teeth of people with periodontal disease.
