How to Clean and Store Your Toothbrush the Right Way

Most people rinse their toothbrush, set it down, and don’t give toothbrush storage much thought. However, how you clean and store your toothbrush matters more than you might expect. A poorly maintained toothbrush can harbor bacteria and become less effective over time. This guide will walk you through:

How to Clean and Sanitize Your Toothbrush

Keeping your toothbrush clean starts with simple daily habits and a few optional deep cleaning methods.

Daily Cleaning

Per American Dental Association (ADA) recommendations, after every use, rinse your toothbrush thoroughly under running water to remove toothpaste, food particles, and debris.

Weekly Sanitizing Options

If you want a deeper clean once a week, the following methods are safe and effective:

• Antibacterial mouthwash: Soak bristles for at least 20 seconds to help reduce bacteria.
• 3% Hydrogen peroxide solution: Mix 1 teaspoon in 1 cup of water and soak briefly.
• Boiling water: This cleaning method is effective but not ideal for frequent use, as heat can damage the bristles.
• UV toothbrush sanitizers: UV toothbrush sanitizers are effective in decreasing the bacterial load on toothbrushes, leading to lowering the amount of oral bacteria and reducing gum inflammation, cavities, and bad breath.
  
  
  
  

What’s the Best Way to Store Your Toothbrush?

Store upright and let it air dry.

Moisture encourages bacterial growth. The ADA recommends keeping your toothbrush upright in an open container to allow it to air dry between uses. This helps reduce bacteria buildup that can occur from toothbrush covers.

Are you a traveler? If so, covers are fine as long as you remove the toothbrush and allow it to fully air dry once you get home or to your destination.

Keep your toothbrush away from the toilet.

Flushing can release airborne particles into the surrounding area. Storing the toothbrush a few feet away, in a medicine cabinet, or closing the toilet lid before flushing, helps to reduce exposure.

Keep toothbrushes separate.

Store toothbrushes separately and avoid letting the brush heads touch to help reduce the spread of germs, even if it’s your family members.

Avoid the sink splash zone.

Toothbrush holders positioned away from the faucet reduce exposure to contaminated water droplets.

When Should You Replace Your Toothbrush?

Knowing when to replace your toothbrush is essential for effective oral care. The ADA recommendation is to replace your toothbrush or electric brush head every 3-4 months or sooner if the toothbrush shows signs of losing the ability to effectively clean along the gumline and between teeth. For example:

• If the bristles are frayed or splayed
• The toothbrush looks worn or discolored
  
  

Other times when you replace your toothbrush sooner includes if:

• You’ve been sick (especially with viral or bacteria illness, such as flu or strep)
• Someone in your household has been ill
  
  

Easy tip: Replace your toothbrush at the start of each season to stay on schedule.

Quick Answers to Common Toothbrush Questions

Should You Cover Your Toothbrush?
No. At home, covering the toothbrush traps moisture and may increase bacterial growth. Keep it uncovered and upright so it can air dry. Covers are fine temporarily for travel.

How Do You Sanitize a Toothbrush?
Soak the bristles in antibacterial mouthwash for at least 20 seconds or use diluted hydrogen peroxide solution. Daily toothbrush rinsing with water remains the most important habit.

When Should You Replace Your Toothbrush After Being Sick?
Replace it as soon as you recover. This helps prevent reintroducing bacteria or viruses into your body.
