Learn how to choose the right TePe Angle interdental brush size and use it effectively for tight spaces. Includes sizing guide, usage tips, and fit guidance.
Quick answer
Choose the TePe Angle interdental brush that matches your gap size: start with the 0.6 mm (ISO 3) for tight spaces between molars, and use the angled head to reach back teeth comfortably.
Why size matters for interdental brushes
Using the wrong size can damage gums or fail to clean properly. TePe Angle brushes come in six color-coded sizes from 0.4 mm to 1.3 mm, each designed for a specific gap width. The 0.6 mm (ISO 3) size is a common starting point for tight spaces between back teeth.
Angle vs straight: what works where
The angled head of the TePe Angle brush helps you reach back molars and premolars without straining your wrist. Straight brushes may be easier for front teeth gaps, but the Angle design is better for difficult-to-reach areas. If you have braces or bridges, the angle can also help navigate around hardware.
How to choose and use your TePe Angle brush
- Start with the smallest size: If you're new to interdental brushes, begin with the 0.4 mm (ISO 2) or 0.6 mm (ISO 3) size. Gently insert between teeth; if it slides without force, it's the right size. If it bends or resists, go smaller. Never force a brush into a gap—it can injure gums.
- Match color to gap width: TePe uses a universal color code: yellow (0.4 mm), red (0.5 mm), blue (0.6 mm), green (0.8 mm), pink (1.1 mm), orange (1.3 mm). Check your dentist's recommendation or use a gap gauge to find your size.
- Use the angle for back teeth: Hold the brush like a pencil and angle the head toward the gum line. Insert gently between molars and move back and forth a few times. Rinse the brush after each gap. Replace the brush when bristles wear out—usually after 1–2 weeks.
