Quick Answer

To find your perfect TePe interdental brush, start with the smallest size that fits snugly into your gap without forcing. If you have tight spaces, choose a smaller ISO size like the TePe Original Red (0.5 mm); for larger gaps, opt for a bigger size like the TePe Original Yellow (0.7 mm). Always consult your dentist if you're unsure, and consider Extra Soft options for sensitive gums.

Choosing the right interdental brush size is crucial for effective cleaning between your teeth. Using a brush that's too small won't remove plaque effectively, while one that's too large can damage your gums. TePe offers a range of color-coded sizes to fit different gaps, but how do you know which one is right for you?

This guide will help you understand TePe's sizing system and provide clear decision rules to match your tooth gaps. Whether you have tight spaces or wider gaps, you'll learn how to select the perfect brush for your oral care routine.

Understanding TePe Interdental Brush Sizes

TePe interdental brushes come in nine color-coded sizes, each designed for different gap widths. The colors correspond to ISO sizes, which indicate the diameter of the brush in millimeters. For example, the TePe Original Red has an ISO size of 2 (0.5 mm), while the TePe Original Blue is ISO 3 (0.6 mm), and the TePe Original Yellow is ISO 4 (0.7 mm).

Choosing the right size is essential: a brush that is too small won't clean effectively, and one that is too large can cause gum irritation. The goal is to find a brush that fits snugly but slides in without force. If you're unsure, start with a smaller size and gradually increase until you find the best fit.

  • Color coding helps you quickly identify sizes: red (0.5 mm), blue (0.6 mm), yellow (0.7 mm), and so on.
  • Always test a new size gently; if it causes pain or bleeding, try a smaller size.

Matching Brush Size to Your Tooth Gaps

To match your brush size to your gaps, consider the space between your teeth. Tight gaps typically require smaller sizes like the TePe Original Red (0.5 mm) or Blue (0.6 mm). Medium gaps may benefit from the TePe Original Yellow (0.7 mm), while larger gaps might need even bigger sizes.

For sensitive teeth or gums, TePe offers Extra Soft brushes with softer bristles, such as the TePe Extra Soft Blue (0.6 mm) or TePe Extra Soft Purple (1.1 mm). These are ideal for those with sensitivity, dry mouth, or after oral surgery.

  • If you're between sizes, choose the smaller one to avoid gum damage.
  • Consider your gum health: if you have receding gums, you may need a larger size to fill the space.

How to Test the Fit

When trying a new interdental brush, insert it gently between your teeth. It should slide in with slight resistance but not require force. If you feel pain or the brush bends excessively, it's too large. If it slides in too easily without touching the sides, it's too small.

Repeat this test on different gaps, as the size may vary across your mouth. You might need multiple sizes to clean all your teeth effectively. Many users find they use two or three different sizes for their entire mouth.

  • Start with the smallest size that fits, then adjust as needed.
  • Consult your dentist or hygienist for a professional recommendation.

Decision Rules for Choosing Your TePe Brush Size

  • Tight gaps (0.5 mm or less): Choose the TePe Original Red (0.5 mm) or Extra Soft Blue (0.6 mm) for gentle cleaning. Start with the smallest size; if it slides in with resistance, it's correct.
  • Medium gaps (0.6–0.7 mm): Opt for the TePe Original Blue (0.6 mm) or Yellow (0.7 mm) for effective plaque removal. These sizes fit most average gaps and are a good starting point.
  • Wider gaps (1.0 mm and above): Consider larger sizes like the TePe Extra Soft Purple (1.1 mm) for more substantial spaces. Ensure the brush fills the gap without forcing; if it bends, size down.
