Experts say you should swap your toothbrush out every 3 to 4 months.
Though this advice sounds simple, many people forget to make the change on time. Your toothbrush is essential to your daily health, serving as your primary tool for scrubbing away plaque, food particles, and harmful bacteria from your teeth and gums.
Over time, however, it becomes less effective, and if you don’t replace it, it can even start to do more harm than good.
3 Key Reasons to Replace Your Toothbrush Every 3 Months
According to the American Dental Association (ADA), you should replace your toothbrush every three to four months, or sooner if the bristles begin to deteriorate.
1. Bacterial Accumulation
Toothbrushes can become breeding grounds for bacteria, especially when stored in moist environments. While the presence of bacteria on toothbrushes doesn’t necessarily lead to adverse health effects, it’s advisable to replace toothbrushes regularly to minimize potential risks.
2. Risk of Gum Irritation
Worn-out bristles lose their gentle touch, making them rough on your gums and possibly leading to discomfort or even gum damage. Using a toothbrush with soft, intact bristles helps ensure gentle cleaning and protects gum health.
3. Post-Illness Hygiene Tip
Once you have recovered from being sick, it’s wise to toss your old toothbrush to avoid lingering germs and reinfection. While the risk of re-infection from a toothbrush is low, changing it can help prevent the potential spread of germs.
How Often Should You Change Your Electric Toothbrush Head?
Just like manual brushes, electric toothbrush heads need a refresh every 3 months to maintain optimal cleaning power.
Even though electric brushes can clean more efficiently than manual ones, their bristles wear out too. And since they move faster and vibrate more, the bristles may even wear out faster than manual brushes.
If you notice the bristles spreading out or changing color, it’s time to change the head. Some brands, like Oral-B or Philips Sonicare, even offer heads with color indicators that fade to show it’s time for a change.
What If You Have Been Sick?
Changing your toothbrush or toothbrush head immediately after recovery is best if you have had a cold, flu, sore throat, or any other infection.
Here’s why:
- Germs can live on your toothbrush bristles.
- There’s a risk of re-infecting yourself.
Your toothbrush may still contain bacteria or viruses even after you feel better. It’s a small cost to prevent another round of illness.
What Are the Risks of Not Replacing Your Toothbrush?
Holding onto an old toothbrush might seem harmless, but it can quietly sabotage your oral health.
- Tooth decay and cavities can result from worn bristles that just cannot do the job.
- Old brushes can harbor bacteria, increasing your risk of gum disease.
- Your breath may smell less than fresh if bacteria remain on the bristles.
- If you have mouth sores or cuts, a bacteria-loaded brush can trigger infections.
What If You Wear Braces?
If you wear braces, you should change your toothbrush even more often, possibly every 1 to 2 months.
Braces create more friction against the bristles, causing them to wear out faster. Plus, they make cleaning all parts of your teeth harder, so you need a brush in top condition to do the job properly.
You can also consider using special orthodontic toothbrushes designed for braces.
5 Crucial Tips to Take Care of Your Toothbrush
Taking proper care of your toothbrush helps it stay clean and last the full 3 months. It also protects your mouth from germs and bacteria.
1. Give It a Good Rinse After Each Use
Once you’re done brushing, thoroughly rinse your toothbrush under running water to clear out any leftover toothpaste, food bits, and germs.
2. Let it air dry in an upright position
Place your toothbrush standing up (like in a cup or holder) and let it dry completely in the open air. Don’t keep it lying flat or touching other brushes, this can spread germs.
3. Never share your toothbrush
Sharing toothbrushes, even with family members, is unsafe. Everyone has different bacteria in their mouth, and sharing can transfer germs that cause infections or illness.
4. Avoid closed or covered containers for long periods
Putting your toothbrush in a travel case or cap might seem clean, but if it stays wet inside, bacteria can grow faster. If you do use a cover while traveling, make sure to uncover it as soon as you are home and let it dry properly.
5. Store It Far from the Toilet
Flushing can send microscopic droplets into the air, and you don’t want those landing on your bristles.
