Interdental brushes are small brushes that help ensure full hygiene between teeth. They are often recommended for people who use bridges, fixed prostheses, or braces—but anyone can use them. When used correctly, they provide significant benefits to oral health.
There are various types of interdental brushes, classified by numbers and color codes. To choose the right one, it’s important to consult a dentist. Using the wrong brush can injure or damage the gums.
What Is an Interdental Brush?
An interdental brush is a small-headed brush designed to clean the spaces between teeth. It is commonly used as an alternative or complement to dental floss, especially when floss cannot be used. It effectively removes plaque, food particles, and bacteria from between teeth.
These brushes play an important role in oral hygiene, especially for individuals with implants, braces, bridges, gum recession, or wide gaps between teeth. Because they reach areas a regular toothbrush cannot, they provide deeper cleaning and help prevent gum disease.
Features of interdental brushes:
- Available in different diameters and sizes
- Flexible and fine brush tips
- Can have a metal or plastic handle
- Used as an alternative to dental floss
- Suitable for daily use
- Portable and hygienic
- Distinguished by color codes
Interdental Brush Sizes
Interdental brushes come in various sizes to accommodate different gaps between teeth. These sizes are expressed in millimeters (mm) and are color-coded accordingly.
To choose the correct size, a dentist should be consulted. Using the wrong size may harm the gums and fail to provide proper cleaning.
| Size | Color Code | Usage Area |
|---|---|---|
| 0.4 mm – 0.5 mm | Pink | Very narrow gaps |
| 0.6 mm – 0.7 mm | Orange | Narrow gaps |
