Keeping your toothbrush clean is essential for maintaining good oral hygiene, but the process doesn’t have to be complicated. Over the years, people have experimented with different methods—running toothbrushes through dishwashers, soaking them in mouthwash, or even using UV sanitizers. But are these methods necessary? Experts say no.
Here’s a simple, effective guide to ensure your toothbrush stays clean and ready to use.
1. Rinse with hot water
The simplest way to clean your toothbrush is by thoroughly rinsing it with hot water. This step removes toothpaste residue and food particles effectively. According to dental experts, this is all you need to do, as the natural bacteria in your mouth aren’t harmful and play a vital role in maintaining oral health.
Tips for keeping your toothbrush clean
1. Air-dry completely
Bacteria on your toothbrush are anaerobic, meaning they can’t survive in oxygen. Letting your toothbrush air-dry kills most of the bacteria naturally.
2. Store it properly
Store your toothbrush upright in an open-air holder. Avoid using travel cases or storing it in closed spaces like drawers, as these environments promote mold and harmful bacterial growth.
3. Replace after illness
If you’ve been sick or had a fungal or viral infection, replace your toothbrush at the start and end of treatment. This prevents lingering bacteria from causing reinfection.
4. Don’t share toothbrushes
Sharing toothbrushes transfers bacteria between users, disrupting the natural balance of oral flora. Keep toothbrushes stored separately and avoid contact between multiple brushes.
5. Replace regularly
Follow the ADA’s recommendation to replace your toothbrush every three to four months. If the bristles appear frayed or discolored sooner, replace it immediately.
Pro tip: Alternate between two toothbrushes
Using two toothbrushes and alternating between them allows one to dry completely, reducing bacterial buildup.
Debunking common myths
You don’t need to boil your toothbrush, freeze it, or invest in expensive sanitizers. These methods can damage the bristles, reducing the toothbrush’s effectiveness. Stick to the basics—hot water, proper storage, and regular replacement.
When in doubt, get a new toothbrush
If you’re unsure whether your toothbrush is effective, err on the side of caution and replace it. Investing in a fresh toothbrush is far easier than trying to sterilize an old one.
