Do you know if it’s time to replace your toothbrush? If you can’t remember the last time you did it, it might be time for a new one! Using a fresh toothbrush is one of the easiest ways to keep your mouth healthy. Old or worn-out bristles can’t clean your teeth the way they should. Worse, they can even hurt your gums or leave behind plaque. In this post, we’ll show you how to tell when it’s time for a new brush and give you a few tips to keep your smile in top shape.

Follow the 3-Month Rule for Toothbrushes

To keep your smile clean and healthy, we recommend replacing your toothbrush at least every three months. This goes for both manual toothbrushes and electric brush heads.

Why do you need to replace a toothbrush after 3 months?

After a few months of use, bristles start to wear out. That’s when they usually start to bend or fray, and the nylon in the bristles loses its integrity, becoming more porous and less effective at cleaning.

The American Dental Association (ADA) says to swap your toothbrush every three to four months in general, but sometimes you’ll need to replace it even sooner.

Signs You Need a New Toothbrush

Here are some clear signs it’s time to toss your toothbrush and grab a new one:

• Frayed or bent bristles – If the bristles are sticking out in different directions, they won’t clean well and could hurt your gums.
• Discolored bristles – Stains or changes in color can mean your brush is getting old or full of bacteria.
• Strange smells – A toothbrush that smells bad isn’t safe to keep using.
• You’ve been sick – We’ll cover more on this below!
• Electric brush heads show wear – Some electric brushes have bristles that fade in color to show it’s time for a replacement.

Even if your toothbrush still looks okay, it’s smart to set a reminder every three months. That way, you never forget to switch it out.

Should you replace your toothbrush after you’ve been sick?

In general, it’s a good idea! If you’ve had a cold, the flu, strep throat, or even a cold sore (which is caused by the herpes virus), it’s best to replace your toothbrush as soon as you’re feeling better.

Why? Because viruses and bacteria can stick to the bristles. You don’t want to reintroduce germs into your mouth and risk getting sick again. Strep bacteria and the herpes virus are particularly effective at hanging around and causing trouble later. Replacing your brush helps protect your health and keeps your immune system focused on healing, not fighting off another round of illness.

What Does It Mean If Your Toothbrush Looks Frayed?

Do your bristles start fanning out or curling up after just a few weeks? If so, you may be brushing too hard.

Many people think brushing harder means a better clean, but that’s not true. Scrubbing your teeth can actually damage your enamel and irritate your gums. Over time, this can lead to sensitive teeth, damage to your enamel, and possibly even gum recession.

Instead, try brushing with gentle pressure for two full minutes, twice a day. To break an aggressive brushing habit, try this:

• Set the toothbrush at the gum line, covering one or two teeth.
• Angle the brush at about 45 degrees toward the gum line.
• Using short, gentle strokes, brush only those two teeth for a few seconds.
• Lift the brush, and gently sweep from the gums, down the length of the tooth, like you’re trying to encourage the gums to cover more of the tooth surface.
• Move on to the next set of teeth.

You can also try brushing with your non-dominant hand, which makes it easier to stay gentle and concentrate on what you’re doing.

If you use an electric toothbrush like Sonicare, let the bristles do the work! Slowly drag your toothbrush along the gum line, gently massaging each tooth one by one.

Do You Need to Replace an Electric Brush Head Every 3 Months?

Yes! For an electric toothbrush, replace the brush head every 3 months. Some brands have bristles that fade to show when it’s time for a new one or may have a signal that lights up to let you know your brush head is too old.

Electric toothbrushes can make brushing easier, especially if you have trouble brushing for the full two minutes. But no matter which kind you use, the most important thing is to keep your brush fresh and clean.

Toothbrush Care Tips

A little care goes a long way. Follow these tips to keep your toothbrush in good shape between replacements:

• Rinse your brush well after each use and try to shake out as much water as possible.
• Store it upright in a cup or holder so it can air-dry.
• Don’t cover it or keep it in a closed case. This can trap moisture and help bacteria grow.
• Never share your toothbrush, even with family members.

Cleaning your toothbrush occasionally with hot water and making sure it can dry completely between uses is usually enough to keep your brush fresh. However, you can soak your toothbrush in antimicrobial mouthwash, hydrogen peroxide, or denture cleanser for a deeper clean. Just be sure to rinse it really well to get rid of any residue. If you’re into gadgets, you could get a UV toothbrush sanitizer to keep your brush extra clean.
