Bottom line
Using the current direct-sale prices and a 3-month head replacement interval, our transparent model estimates about $158.88 for SURI Pro 2.0 versus $224.94 for Oral-B iO Series 3 over three years. That is a scenario, not a guaranteed spend—sale prices and replacement-head deals can change.
Current price inputs
| SURI Pro 2.0 | Oral-B iO Series 3 | |
|---|---|---|
| Handle | $89.25 promotional | $59.99 promotional |
| Replacement heads | $18.99 / 3 | $29.99 / 2 |
| Cost per replacement head | $6.33 | $14.99 |
| Pressure sensor | Yes, Pro 2.0 | Yes |
| Published head-change interval | 3 months | 3 months |
Where SURI wins
- Lower replacement-head cost in the current direct-price snapshot.
- Long-battery/travel positioning and slim aluminum design.
- 100-day trial language published by SURI.
- Plant-based head/recycling proposition creates a real differentiation beyond app features.
Where Oral-B wins
- Lower current handle price.
- Broad retail availability and a large installed ecosystem.
- Round oscillating-rotating iO head rather than SURI's sonic format—some buyers strongly prefer one motion/style.
- Frequent retailer promotions can materially reduce the ownership-cost gap.

Use a preset, then change any number. This is a cost model—not a recommendation about how often a dental appliance or brush head should be replaced.
