How Often Should You Replace Your Toothbrush?


Do you remember the last time you got a new toothbrush? We throw away expired meals, replenish vitamins and supplements, and change cosmetic products on a regular basis. Yet, regarding health and beauty, our oral hygiene receives less care or consideration than other parts of our regimen. However, specific key regulations and suggestions must be followed to maintain excellent oral health. Visit to learn more about maintaining dental health.

How often should you replace your toothbrush?

The American Dental Association (ADA) and most dentists recommend replacing your toothbrush after three months of use. Brushes wear out with everyday use and become less efficient at removing plaque from teeth and gums. According to studies, the bristles split down and lose their strength after three months.

Another thing we do not usually consider (and do not wish to think about) is that bacteria can lurk and build up in the bristles of our toothbrushes. As a result, replacing your toothbrush after a cold is essential to avoid reinfection.  

Fungus and germs can grow if the bristles are not adequately cared for. After use, rinse and dry your toothbrush appropriately before keeping it uncovered vertically and away from other used toothbrushes. If traveling, cover your toothbrush head to guard it and limit bacterial transmission.

If you cannot recall how long it has been, look at the condition of your toothbrush head, especially if the bristles are fanning out, worn out, or frayed, or if you see dark color changes indicate mold.

What will happen if you do not change your toothbrush often enough?

If the fact that germs and fungi grow on your toothbrush bristles over time is not sufficient motivation to change your toothbrush more frequently, there are a number of other hazards and unwelcome issues that come with not replacing your toothbrush. One problem is that obsolete toothbrushes become inefficient at clearing plaque from your teeth, causing gingivitis. Gingivitis, if left untreated, causes infection, leading to tooth loss.

Things to consider when buying dental products

During your next dental screening and cleaning, ask your dentist for guidance on what you should buy depending on your specific needs, oral health, etc.

Buy toothbrushes with soft bristles, as stiff bristles can damage your teeth and gums. Choose a toothbrush head size that only brushes one or two teeth at a time, use ADA-approved fluoride toothpaste, and consider using mouthwash to reduce and fight plaque and gingivitis, and yes, do not forget to floss!
