If you brush your teeth twice a day, you’re already doing something great for your smile. Brushing helps remove plaque, freshens your breath and protects your teeth from decay. For many people, it feels like that should be enough. But even with excellent brushing habits, there’s one important area that often gets overlooked – the spaces between your teeth.
Your toothbrush does a great job on the surfaces it can reach, but it can’t fully clean between teeth or just below the gumline. Those small, hard-to-reach areas are where plaque and food particles tend to build up the most. Over time, that buildup can lead to cavities, gum irritation and other oral health concerns.
That’s why brushing alone isn’t enough for a truly clean smile, and why interdental cleaning — or even a water flosser vs. floss comparison — plays such an important role in keeping your teeth and gums healthy.
What is interdental cleaning?
Interdental cleaning simply means cleaning the spaces between your teeth. These are the tight areas where toothbrush bristles can’t reach, no matter how carefully you brush. Food particles and plaque love to settle there, especially along the gumline.
Floss is the most well-known interdental cleaning tool, but it’s not the only option. Interdental brushes, soft picks and water flossers can also help clean these hard-to-reach spots. The goal is the same: remove plaque before it can cause problems.
Why brushing alone misses the mark
Brushing is excellent for cleaning the front, back and chewing surfaces of your teeth. It removes surface plaque and helps protect enamel. However, your toothbrush can’t slide between teeth or fully clean under the gumline.
Think of it like washing your hands without cleaning between your fingers. You’re doing most of the job, but important areas are still being missed.
Brushing alone can leave a significant portion of your tooth surfaces uncleaned. Over time, plaque that stays between the teeth can harden into tartar, irritate the gums, and create the perfect environment for cavities and gum disease.
What happens when you skip interdental cleaning
When plaque sits between teeth day after day, it doesn’t just go away. It builds up and can lead to several common dental issues, including:
- Cavities that form between teeth
- Red, swollen or bleeding gums
- Persistent bad breath
- Gum disease that can progress if left untreated
Many patients are surprised when cavities show up between teeth, especially if they brush regularly. In most cases, the missing piece is interdental cleaning.
The benefits of cleaning between your teeth
Adding interdental cleaning to your daily routine doesn’t take long, but it can make a big difference. Patients who clean between their teeth consistently often experience:
- Healthier gums with less bleeding
- Reduced plaque buildup
- Lower risk of cavities in hard-to-see areas
- Fresher breath
It’s one of the simplest ways to protect your smile between dental visits.
Choosing the right tool for you
There’s no one-size-fits-all approach to interdental cleaning. Some people prefer traditional dental floss, especially if their teeth are close together. Others find interdental brushes or soft picks easier to use, particularly if they have wider spaces, crowns, bridges or braces.
Water flossers are another popular option, especially for patients who struggle with string floss. They can be gentle, effective and easy to use – and consistency matters more than the specific tool.
The best choice is the one you’ll use every day.
Tips for making it a daily habit
If interdental cleaning feels awkward or uncomfortable at first, that’s normal. Here are a few tips to make it easier:
- Start slowly and be gentle with your gums
- Clean between teeth once a day, ideally before brushing
- Don’t force floss or brushes into tight spaces
- Ask your hygienist for a quick demonstration at your next visit
It usually only takes a few days for a routine to feel natural.

Skipping interdental cleaning can lead to plaque buildup, cavities between teeth, gum irritation, bad breath and an increased risk of gum disease.
What tools can I use for interdental cleaning?
Options include traditional dental floss, interdental brushes, soft picks and water flossers. The best tool is the one that fits your needs and that you’ll use consistently.
How often should I clean between my teeth?
Most dentists recommend cleaning between your teeth once a day to help remove plaque and support healthy gums.
Are water flossers as effective as traditional floss?
