What’s A Proxabrush? (Interdental Brush)

Go Between Proxabrushes

Amazing! You just came from your dentist and this time you DIDN’T get the “you need to floss more” speech! What gives? I am here to tell you as a dental hygienist that flossing is not recommended in the same way it used to be. You now have the option of a Proxabrush to take its place. But wait, what’s a Proxabrush?

A Proxabrush is a type of interdental brush. I will explain in detail this alternative to floss for cleaning between your teeth. Let’s face it, people are not flossing. Now you have a choice! Most people talk about how they do not like putting their fingers inside their mouths to floss. I get it. It is gross even with the cleanest of hands. We live in a germaphobe-type world and who wants to transmit and spread germs!

I will discuss why cleaning between your teeth is necessary, types of Proxabrushes and proper technique for using them so read on…

People Do Not Like to Floss…

More and more people are seeking alternatives to using standard string floss. Dental professionals want to help individuals meet their home care needs by offering solutions to the lack of flossing. Only half of people floss daily and about one in every five people report not flossing at all.
The majority of people who report not flossing regularly do so for a variety of reasons. These include; lack of dexterity, trouble reaching areas, hands being too large to fit in the mouth or just simply not wanting to place hands inside of the mouth.

A study available on PubMed from the National Society for Biotechnology Information (NSBI) concludes the effectiveness of interdental (between the teeth) cleaning for improving the health of the mouth. This study showed the effectiveness of Proxabrush use being the most effective means of removing plaque and food debris between the teeth versus flossing.

Why You Need to Clean Between Your Teeth

What is the big deal about removing plaque and debris from between our teeth? Why not just leave it there? Good question. There is a lot going on that you may not be aware of if you brush only but ignore the important in between areas of your teeth.

We now know the detrimental effect of dental plaque and biofilm and its role in dental disease and inflammation. By best controlling the amount of plaque, you will be reducing the amount of toxins given off by plaque. Studies show that gum disease is a result of inflammation produced in response to these toxins. You can learn more about gum disease and controlling inflammation in a related article.

Studies show that in addition to brushing, people who used Proxabrushes or oral irrigation devices had promising results. The results showed they were as effective or more effective as standard string floss in removing bacterial plaque and reducing signs of gum disease.

According to the American Dental Association (ADA), cleaning between the teeth is essential. The ADA states that interdental cleaning removes plaque and debris from between teeth that can lead to gum disease and cavities. These are areas a toothbrush can’t effectively clean.

Wikipedia states that dental plaque can contain up to 1,000 species of bacteria. Some of these are beneficial to us and some are harmful. It is important to maintain a balance of these bacteria to maintain dental health.

Oral probiotics have been shown to maintain this balance. Probiotics for the mouth will help crowd out the bad bacteria making room for the beneficial bacteria. Effectively cleaning between your teeth will also keep the balance in check to prevent decay (cavities) and periodontal disease (gum disease). Your best chance of doing this is by using the right tool- a Proxabrush!

What’s a Proxabrush?

Proxabrush is a brand name of an interdental brush. It is made by the company Butler GUM. Proxabrush is the #1 selling interdental brush available today and is the most recommended brush by dental professionals. An interdental brush is a hand held tool of varying lengths with a small brush attached to its end for cleaning between your teeth.

The handle can be small in the case of a portable Proxabrush or it can be as long as your toothbrush handle. The longer units are designed for better access for those people who have hard to reach back teeth to clean between. However, the pocket-size versions are more convenient to use and are more popular.

The bristles are soft and flexible and come in different sizes to fit your needs. The smallest brushes are designed for tight spaces or for those who have teeth that are close together. Proxabrushes with wider brushes are good for those who have more room between their teeth. There is also a medium-sized brush and an ultra-tight size for extremely tight teeth.

The brush that works best for you will depend on the size of the spaces between your teeth. Some people have teeth that are close together in one area of the mouth yet wider gaps between other teeth. For these people, having more than one size of Proxabrush on hand is ideal so the different sizes can be used appropriately.

How to Use a Proxabrush

It is recommended to use an interdental Proxabrush to clean in-between your teeth once a day. This can be used in place of traditional floss and should be part of your dental hygiene routine. Proxabrush use is not intended to replace daily brushing so it is important to continue to brush twice a day with a manual or electric toothbrush. An electric toothbrush will remove more bacterial plaque than a manual toothbrush.

Step 1 – Brush your teeth for 2 minutes as you normally would using an electric or manual toothbrush

Step 2 – Choose the correct size Proxabrush interdental brush depending on your needs (size of spaces between teeth)

Step 3 – Without using force, gently slide the brush head between your teeth

Step 4 – Moving in a back and forth type of motion, gently loosen plaque and food debris from between the teeth

Step 5 – Swish with water and spit out to remove any loosened debris

Step 6 – Rinse off the Proxabrush with water, replace cover and allow it to air dry through vented cover

    Wow, what an amazing thing! I’ve never in my life heard of! (Probably a sign I need to go to the dentist more….) I’ve been told a couple of times that a Waterpik is superior to flossing in its ability to get plaque and food particles out from between my teeth. How would you rank the Proxabrush as opposed to a Waterpik?

  3. Kevin

    Wow, I probably need an interdental brush, thank you for bringing this to my attention! I hardly ever floss. I find that using the standard string floss is super awkward especially trying to floss the teeth at the back of my mouth. This brush definitely seems easier for me to floss my front teeth. I am wondering, though, is it uncomfortable getting between the teeth in the back?

    1. Michelle Mussehl, RDH


      There are different sizes to make using them comfortable for you depending on where you need to use them. Proxabrush has the variation in sizes because everyone has different needs. Most people have more space between the back teeth versus the front. If your teeth are tighter in the back, you will want to use the ultra-tight or tight size bristle.

    One of my questions is the differences in effectiveness not only between floss and interdental brushes but also between toothpicks. The researcher acknowledged the idea that proximal sides of teeth usually have some curvature or concavity present. Therefore, when using the different methods, the effectiveness would vary, although, at the very least, some proximal plaque would be removed with each approach.

    I’ve been using the Butler GUM Go-Between-tight for many years and they were recommended by my dentist. They are very beneficial for your overall health as your teeth can make a negative impact on your health if you do not floss and keep your gums in good condition.

     I Loved reading your article and would like to share this educational article in my Facebook group if you give me permission.

      Md. Asraful Islam,

      Many dental professionals recommend the Go-Between Proxabrush from Butler GUM. Flossing is still recommended. However, considering the lack of compliance with flossing, it is nice to offer patients an alternative that works for cleaning between their teeth. What works best is what works for you! The use of toothpicks is not encouraged by dental professionals. There is a “v-like” shaped area of tissue between our teeth called the interdental papillae. This papillae is designed to keep plaque and food debris from collecting between our teeth. With regular use of a wooden toothpick, this area can become callused and blunted which creates more space between our teeth. This then invites more plaque and debris to collect in these hard to reach areas. Using a Proxabrush will gently and thoroughly clean this area without damaging the tissue between our teeth.

      Regards and please share this information with your Facebook group.

    Not a big fan of flossing myself. I don’t floss until I feel something is stuck in between my teeth. I only do it maybe once a week to be honest, and this is probably due to laziness and the fact that it’s not very convenient. I only heard about the interdental brush recently and this seems like a much better alternative to flossing. Another reason I seldom floss is because my gums tend to bleed whenever I floss, would this also occur with the interdental brushes?

    1. Michelle Mussehl, RDH


      I realize flossing is not convenient. An interdental brush (Proxabrush) makes the tedious task of cleaning between your teeth much easier. Bleeding usually occurs due to the lack of regular cleaning between your teeth. When plaque is left between your teeth, it gives off toxins which cause inflammation of your gums. This inflammation is what causes the bleeding. With regular removal of plaque, the gums will become healthier and bleeding will no longer occur. With regular use of a Proxabrush (or floss) bleeding will be a thing of the past.

    Wow, what an awesome review. Your article signifies the degree of expertise you have and I am more than happy to come across your works. I suffer from a hole in my tooth which is a cavity. This may be a result of food particles stuck between my teeth and the works of the numerous bacteria you just mentioned. I have suffered terrible pain and my dentist’s advice is that the tooth be removed. Can a Proxabrush really help me as far as this tooth condition (hole) is concerned? Though I know it will help me in the future.

    1. Michelle Mussehl, RDH


      A Proxabrush will help keep this area you have mentioned clean until you have a chance to get it removed. A hole in a tooth usually indicates a cavity. Once a cavity has broken through the outer layer of enamel, it travels quickly into the next layer of tooth called the dentin. This is when you get the “hole” that you mentioned. At this stage, a cavity cannot get better on its own, it needs to be restored by your dentist. It sounds as if your dentist feels that the decay has progressed too far and can no longer be restored. This is most likely why your dentist is recommending the tooth be removed. By using a Proxabrush in the meantime, you can keep the area clean and it will help with the pain. Going forward, you can use a Proxabrush to keep the rest of your teeth clean and prevent this from happening to your other teeth.

      Thanks for sharing,

    I truly need to initially value your exertion in assembling this incredible site and composing this article. Many thanks for the extraordinary article about a Proxabrush. After reading your article, I found out how using a  Proxabrush will be beneficial for our teeth. And since I have dental problems it is so perfect for me. I think your article will be very helpful for those who have issues with their teeth and gums. I have a question. My son also has dental problems, so can my son use this brush too? Will it be good for him? I must say that this article is very helpful and informative. I want to share this article on my social media so everyone can learn about it. Thanks!

    1. Michelle Mussehl, RDH


      Yes, absolutely your son can benefit from using a Proxabrush. In fact, children under the age of 8 do not have the dexterity to correctly use floss. A Proxabrush does not take any special skill and is ideal for adults and children of all ages. Children going through braces (ortho) can especially benefit from using a Proxabrush. During ortho, the wires make it difficult to clean between the teeth. Using a Proxabrush will effectively remove plaque and food debris from between the teeth and also around the brackets. 

      Thanks for your questions,

    1. Michelle Mussehl, RDH

      The fact that you did not take good care of your teeth as a child does not mean it is too late to start now. In fact, it is never too late to start taking better care of your teeth and gums. You can start today by using the right product for cleaning between your teeth.

      Thanks for your kind review of the article ‘What’s A Proxabrush? (Interdental Brush)’ and for your comments. I am glad to hear you are already using one and you now know how very important their use really is. If you brush but do not clean between your teeth, you are leaving behind a substantial amount of disease causing plaque and debris.
