How Often Should I Change My Toothbrush?

Few things in life last forever. Your toothbrush is definitely not one of them. Wear and tear can quickly reduce the effectiveness of your toothbrush making it ineffective in cleaning your teeth. The problem with your toothbrush though is that you may not notice it happening. 

Rather than to just go by how it feels, it’s much better to change it at regular intervals. Your oral health will significantly improve by doing so. So, let’s address the question, “how often should I change my toothbrush?”

When To Change Your Toothbrush

Recommendations from the American Dental Association (ADA) suggest that you should replace your toothbrush every three to four months. The same applies to a regular or electric toothbrush. Let’s see why.

Worn out bristles

Bristles wear out slightly every time you use them. It may not be something you see after each use but over time the bristles become frayed. They then become ineffective at removing plaque from your teeth.


The hygiene of your old toothbrush is also something that can deteriorate over time. Bacteria cling to the bristles and multiply over time. You can reduce the build-up by rinsing the brush under running water and drying it after use. 

Also if you travel with your toothbrush cover the brush head.  You may want to change your toothbrush after recovering from a respiratory illness to avoid reinfection.

Bottom Line: If you can’t remember when you last changed your toothbrush yet the bristles have become frayed or darker in color (possibly due to mold) then it’s time to change your toothbrush for a new one.

What Happens If I Don’t Change My Toothbrush Often Enough?

Remember the two reasons mentioned above why you should replace your toothbrush regularly.

Your toothbrush will not remove plaque effectively if it’s frayed. Plaque build-up leads to gingivitis and periodontitis which is a common cause of tooth loss.

You also wouldn’t want to expose your mouth to bacteria and mold.

What Toothbrush Should I Get?

There are many types of toothbrushes to choose from and each is designed for specific needs. Your dentist should direct you to one that will be effective for you. Generally, dentists favor softer bristles over harder ones to prevent potential damage to your teeth and gums. A toothbrush with a head large enough to cover two teeth at the same time is also usually recommended.

An electric toothbrush is also effective in maintaining good oral health. Some find it advantageous in the removal of plaque stains and reducing gingivitis.

Changing your toothbrush and using it regularly will help you maintain good dental hygiene and help you to avoid many problems such as tooth cavities or advanced periodontal disease. Neglecting these basics can lead to tooth loss.
