BURST Curve Sonic Toothbrush vs Oral-B iO Series 9
Side-by-side comparison of features, pricing, ratings, and alternatives.

The Curve is BURST's compact sonic toothbrush, designed around travel rather than shrunk down from a full-size model. It is TSA-ready and sized to pack, which matters because the usual travel compromise is either carrying a bulky charger and brush or reverting to a manual brush for a week. BURST's positioning is that its products are backed by dental professionals, and the brand was built through a network of hygienists rather than conventional retail. The Curve is shaped to clean every tooth surface rather than just the accessible faces. It sits within a full oral care range including the Pro 2.0 and Original sonic toothbrushes, a kids brush, replacement heads, water flossers, expanding floss, toothpaste, whitening trays and oral health probiotics.
The Oral-B iO Series 9 pairs a magnetic, micro-vibrating brush head with linear magnetic drive technology for a smoother, gentler brushing motion compared to traditional oscillating-rotating brushes, while still delivering thorough plaque removal. A color-coded smart pressure sensor lights up green, yellow, or red on the handle to indicate ideal, acceptable, or excessive brushing pressure, helping prevent gum damage from brushing too hard. The companion app uses the phone camera during brushing to provide an AI-powered 3D mouth map showing which areas were missed or need more attention, turning brushing into a more guided, data-driven routine.
Around $299.99 MSRP.

Decent but has rough edges
Oral-B iO Series 9 is solid overall, though it's not perfect. On the plus side, genuinely useful real-time pressure feedback. That said, app features require a smartphone, which held us back from rating it higher.
