Key points
- Interdental brushes clean the spaces between teeth that a toothbrush cannot reach.
- Choose a size that fits snugly without forcing it; you may need more than one size.
- Insert gently at the gum line and move the brush back and forth a few times in each gap.
- Using them once a day helps reduce plaque, bleeding gums and bad breath.
- They are especially useful with braces, fixed retainers, bridges and implants.
Summary
Brushing only cleans part of each tooth. The surfaces between teeth are where gum disease and decay often start, which is why cleaning between the teeth every day matters.
In this video Dr Sarah shows how to use interdental brushes properly, including choosing the right size and the correct technique. Our dentists and hygienists are happy to show you in person at your next visit.
Questions about this topic
What size interdental brush do I need?
Sizes vary between gaps. Your dentist or hygienist can measure and tell you which ones fit.
Is it normal for my gums to bleed when I start?
Some bleeding can happen at first if gums are inflamed. It often improves with daily cleaning. If it continues, book a check-up.
Are interdental brushes better than floss?
For many people they are easier and more effective where the gaps allow. Floss can be better for very tight contacts.
Can I use interdental brushes with braces?
Yes, they are very helpful for cleaning under the wire and around brackets.
