How Often Should You Change Your Toothbrush?

How often should you change your toothbrush?

Most dentists recommend replacing it every three months—but studies show many people keep theirs for much longer. Worn-out bristles, hidden bacteria, and reduced cleaning power can harm your oral health. The good news? With BrushO’s smart electric toothbrush, every box comes with four replaceable brush heads, providing you a year of easy replacements without the need for extra shopping. Here’s everything you need to know about toothbrush replacement frequency, risks, and tips.

Why Toothbrush Replacement Matters 🪥

A toothbrush is your first line of defense against plaque, cavities, and gum disease. Over time, however, bristles wear down and lose their ability to clean effectively. Even worse, old toothbrushes can harbor bacteria that contribute to oral infections.

Dentist Recommendations: Every 3 Months 🦷

• 3-month rule: The American Dental Association (ADA) and most dentists agree you should replace your toothbrush every 3 months.
• Illness: If you’ve been sick, replace it immediately to avoid reinfection.
• Heavy use: Brushing more than twice a day can wear bristles faster, requiring earlier replacement.

👉 Think of it like car tires—worn bristles simply don’t perform the job anymore.

Signs It’s Time to Change Your Brush Head ⏰

• Bristles look frayed or bent.
• Brushing feels less effective than before.
• Bristles have lost their original color or stiffness.
• Bad smell or discoloration at the base of the brush head.

If you notice any of these, it’s time for a new brush head—even if it hasn’t been 3 months yet.

Risks of Not Replacing Your Toothbrush ⚠️

• Plaque buildup → increases cavity and gum disease risk.
• Oral bacteria growth → contributes to bad breath and infection.
• Reduced brushing performance → even good brushing technique won’t help if the bristles are worn.

Skipping replacements doesn’t save money—it leads to higher dental bills down the line.
