🧠 How to Choose the Right Size & Type

Measure the Gap: Use a toothpick or dental size tool to see which brush fits without forcing.
Comfort Is Key: Choose a brush that fits snugly but doesn’t hurt — it should glide in with minimal resistance.
Durability: Look for sturdy handles and quality bristles — especially if you use them daily.

✅ How to Use Interdental Brushes Correctly

Choose the Right Size
Too small = ineffective. Too large = can hurt gums.
Insert Gently
Don’t force it! Angle slightly toward your gumline for comfort.
Brush Back and Forth
Move the brush a few times between each space.
Rinse and Clean
Rinse your brush after every use and let it air dry.

🦷 Use them once daily, ideally after brushing your teeth.

🗓️ Make It Part of Your Routine

Use After Brushing: Clean away any leftover debris your toothbrush missed.
Combine with Flossing: They don’t replace floss, but work beautifully together for a thorough clean.
Be Consistent: Daily use keeps gums healthy and prevents plaque buildup.

⚠️ Side Effects & Safety Tips

Interdental brushes are very safe when used correctly, but here are a few tips to avoid issues:

Don’t Force It: If the brush doesn’t fit easily, try a smaller size.
Start Slowly: New to it? Expect mild tenderness. Go slow and gently.
Replace Regularly: Every 3–4 weeks or once bristles wear out.
