Do you know how long you’ve had your toothbrush? If it’s been a while, don’t worry. Most people keep their toothbrushes for far too long before replacing them with new ones. You might be wondering, “How often should I change my toothbrush?” The answer depends on a few factors, but we’ll get to that later. In the meantime, let’s look at why it’s so important to replace old brushes regularly.

You should change your toothbrush every three to four months.

A toothbrush is one of the most important tools in your arsenal when it comes to maintaining a healthy smile. However, this little tool can be pretty gross if you don’t take care of it properly. If you fail to properly clean your toothbrush and store it, bacteria can grow on its bristles while they’re still wet from use, which can cause cavities and gum disease.

Here are some tips for keeping your brush as clean as possible:

  • Clean regularly with hot water (or an antibacterial rinse). This will help remove any debris or food particles leftover from brushing that might aggravate gums or contribute to dental decay.
  • Make sure you store your toothbrush upright, so that water doesn’t gather in the handle where bacteria could breed.
  • Replace every three to four months; recycled plastic bristles aren’t good for your mouth!

Buy a new brush after you’ve been sick.

A toothbrush can be a breeding ground for bacteria, and if you’re sick, your immune system is compromised. Therefore, it’s wise to buy a new one after you’ve been sick.

Look for frayed bristles.

You should also look for frayed bristles. If they’re a little more than just worn down, they can damage your gums and teeth. Frayed bristles don’t reach the places in your mouth that need cleaning, so you need to change them out as soon as you notice them. It’s easy to check if you’ve got a brush with frayed bristles: simply run your finger along a few of the longer ones and see if they feel rough or sharp.

In addition to wearing out, the bristles can harbor bacteria that can cause gum disease or other oral health issues. Plus, if you have an electric or sonic toothbrush that vibrates at high speeds when you use it, the vibration may break down the bristles faster than normal (though this isn’t a problem for manual brushes).

As well as being worn down by use over time, your toothbrush may also end up bent and misshapen after repeated bends in its lifespan—and this is problematic because bent bristles aren’t effective at cleaning your teeth as well as straight ones are.

Patient Experience

I’m happy with my last visit and cannot think of anything I’d change. Thank you for the chance to voice my
opinion! – J.F.

Amazing Service

I’ve been going here for years but recently brought in our kiddos. Our oldest needed a filling and was panicked about getting a shot. Dr. Welsh distracted him and she administered the numbing shots so well that he didn’t even know she gave him the shots!! Truly amazing service!


Forward Thinking

I was so relieved you were able to see me. Thank you! New office procedure only adds to the totally smooth flow of your ever gracious office. So forward thinking!


Patient Feedback

My husband, Mack, and I are thrilled to find Dr. Welch since she is truly a biological dentist. We truly wish we’d found her in this area years ago, as I’ve had to fly out to dentists that are beyond just not using mercury. We’re ages 72 & 75, so Dr. Welch will be so helpful with positive aging helped with dentistry…and no concerns about harmful dentisty to our elderly bodies.

Great Team

A Great Team!! Dr. Welch herself is very professional, knowledgeable, takes the time to explain the background to a procedure…and is very friendly. Her staff are the same and the teamwork they show when they work together is at the highest level. Highly recommended.



Dr. Welch and her staff are incredibly knowledgeable and helpful. I felt they cared about the patient more than money. They take the time to explain and care above and beyond what is expected.



Wouldn’t trust my orthodontics and cleanings with anyone else. Always thorough, in and out every time!

Dr. Welch at Wright Parkway Dental Center is by far the best dentist. She does not just look at a person’s teeth and mouth. She truly is concerned for the overall health of her patients.
