How Often Do You Need to Change Your Toothbrush?


You might think that once you’ve had your toothbrush for 3-4 months, it’s time to replace it, but that’s not necessarily the case. It really depends on how well you take care of your toothbrush, which includes proper storage and cleaning after each use. If you do replace your toothbrush when you should, you could end up spending more than $200 on toothbrushes over the course of your lifetime! This blog explores the various factors that determine how often you should replace your toothbrush and presents an in-depth look at the costs associated with frequent replacement.

When To Change Your Toothbrush

Naturally, everyone’s idea of what makes a toothbrush smelly is going to be different, so it can be hard to nail down just how often you should replace your toothbrush. The answer depends on your lifestyle. Many people recommend replacing a toothbrush every three months; however, at Shine Dental Associates, we recommend changing yours after about two months of regular use—especially if you have a compromised immune system or are prone to gum disease or bad breath.

Do You Need To Replace Your Toothbrush More Often Than You Think?

The answer may surprise you. Our dentist and team of hygienists here at Shine Dental Associates are often asked: how often should I replace my toothbrush? This is a very important question for everyone to consider, not just those who have risk factors for dental disease such as gum disease or dry mouth. 

What Happens If I Don’t Change My Toothbrush Often Enough?

Leaving your toothbrush too long without replacing it can lead to a buildup of bacteria, leading to dangerous infections that could even require hospitalization. If you feel like you’re getting sick more often than usual, it may be time to give your toothbrush a serious cleaning. Even if you don’t have any signs of illness, changing your toothbrush every 3-4 months is still a good idea. It’s recommended by most dentists and oral care experts as part of a healthy routine—and who doesn’t want their smile to look great? Our Shine Dental Associates team is always here to help!

Rubber Bristles

The New York State Dental Association recommends replacing your toothbrush every three to four months. But really, should you be replacing it more often than that? Absolutely—in fact, maybe even sooner than that. Your rubber-bristled toothbrush won’t last as long as you might think: According to a study published in 2007 in The Journal of Dentistry, over 50 percent of an ordinary, store-bought brush’s bristles can break down after only six weeks of use.
