Superiority Over Traditional Floss

For many patients, interdental brushes are more effective at cleaning the gaps between teeth than traditional string floss. These small, specially designed brushes can reach into the concave surfaces of the teeth that floss often misses. Their bristles scrub away plaque more efficiently, providing a thorough clean that can be difficult to achieve with thin string. For those with larger gaps or gum recession, they are often the preferred choice.

Research suggests that interdental brushes may remove more plaque than floss in many mouth types. They are especially beneficial for people with bridges, implants, or orthodontic appliances, where standard floss is difficult to use. By incorporating these brushes into your routine, you ensure a deeper clean that significantly reduces the risk of inflammation and decay in those hard-to-access interdental spaces. They are an essential part of modern preventative dentistry.

Finding the Right Size

Interdental brushes come in a variety of sizes, from very fine to quite large. It is crucial to choose the correct size for each space in your mouth. You should feel a slight resistance when sliding the brush between your teeth, but you should never force it. If the brush is too small, it will not remove the plaque. If it is too large, it may cause damage to your gums.

During your next visit to Dr. Amit Sharma Super Speciality Dental Hospital, we can help you determine the appropriate sizes for different parts of your mouth. You may find that you need several different sizes to clean various gaps effectively. Investing time in finding the right fit ensures that you can clean comfortably and effectively without causing any irritation to your gum tissue or damaging your existing dental work.

How to Use Them Correctly

Using an interdental brush is straightforward, but it requires the correct technique. Hold the brush between your thumb and index finger and gently insert it into the space between your teeth at the gum line. Move the brush back and forth several times to dislodge plaque. Do not bend the wire, as it can snap and cause injury. Rinse the brush under water after cleaning each space to remove debris.

If a particular gap is too tight, do not try to force the brush through. Forcing it can damage your gums and the brush itself. Instead, switch to a smaller size or use traditional floss for that specific tight area. With practice, you will become quick and efficient at cleaning between your teeth. Remember, consistency is the foundation of good health, so ensure you take your time to clean every space.

Maintaining Your Brushes

Interdental brushes can be reused for several days, provided they remain in good condition. However, once the bristles become flattened or the wire starts to kink, you should replace the brush immediately. A damaged brush will not clean effectively and could potentially cause injury to your gums. Keep a clean, fresh supply on hand to ensure you can always maintain your daily hygiene routine without interruption.

To keep your brushes hygienic, store them in a clean, dry place. Rinse them thoroughly after every use and let them air dry completely. Do not store them in an enclosed, damp container where bacteria can thrive. By taking simple steps to maintain your tools, you ensure they remain safe and effective for your daily use. A little bit of care goes a long way in your overall health.

Building the Habit

As with flossing, the most important aspect of using interdental brushes is making them a part of your daily life. Keep them in a visible spot near your bathroom sink as a constant reminder to use them. Whether you choose to use them before or after brushing, ensure that this step is completed every single day. Your gums will feel the difference as inflammation reduces and your mouth feels healthier.

Questions patients ask us

Are interdental brushes better than floss?
Many dental professionals consider interdental brushes more effective at plaque removal, particularly in larger gaps or around complex dental work. They are generally easier to use for most people. However, if your teeth are extremely tight together, floss might be the only tool that can fit comfortably and effectively.
Can I reuse interdental brushes?
Yes, you can reuse an interdental brush for a few days until the bristles fray or the wire kinks. Ensure you rinse the brush thoroughly after each use and allow it to dry completely. If the wire bends or the bristles are worn, discard it immediately and use a new one.
How do I know which size to use?
You should feel a light, comfortable resistance as you insert the brush between your teeth. It should not be loose, nor should you have to force it. Our dental team can help you select the right size for each gap during your next check-up, as you might need multiple sizes.
Should I use toothpaste with the brush?
You do not need to use toothpaste with interdental brushes. Their primary purpose is mechanical removal of plaque and trapped food particles from between your teeth. Simply wetting the brush with water is sufficient. The focus should be on the proper technique of moving the brush back and forth to clear debris.
