You’re at the sink. Brushes lined up. And then the usual question:
Was that gap a pink… or a blue?
If you use interdental brushes, you already know the dance. Different gaps need different sizes. Your partner’s sizes aren’t yours. Someone’s pack of TePe or Piksters lives in a drawer, and half the time you’re guessing.
That’s why we built Interdental.
Map your mouth once — then tap gaps as you clean.
Interdental is a free iOS utility that helps you remember the right brush size for every gap between your teeth. Map your mouth once, assign a size to each space, and the next time you’re cleaning you simply tap along as you go. No more standing there trying to recall the colour chart from memory.
Pick TePe or Piksters and match each gap to the size that fits snugly.
It supports TePe and Piksters, with accurate size and colour mapping. And because oral care isn’t a solo sport in most homes, you can set up a profile for each family member — so everyone has their own map, their own brand, and their own progress.
One app, a profile for each person — TePe, Piksters, or mix and match.
No account required. Just a small, focused tool for a fiddly everyday job.
Want to try it?
We’re opening a free iOS beta and we’d love your help. Two minutes is enough: map a few gaps, run one clean, and tell us how it felt.
Feedback makes the app better — use TestFlight’s Send Beta Feedback once you’re in, or email info@interactivecoconut.com. If you’d rather wait for the public launch, you can ask us to email you when it’s out from the same page.
Thanks for giving Interdental a go — we can’t wait to hear what you think.
