Prices reviewed 31 July 2026 . Indicative US prices in USD. Three-year cost assumes replacing the head every 3 months (12 heads); brush price plus head price shown separately so you can adjust.

About $2 each for generic-compatible ones up to $10-$12 for premium branded (Sonicare, Oral-B iO). At one every 3 months, that is 4 a year, and over 3 years the heads can beat the brush price. That is why the real comparison is the total.
Budget brands like Bitvae and Fairywill, cheap handle and ~$2 heads, land near $50-$60 over three years. Among big names, a basic Oral-B is good value because it takes cheap third-party heads.
They clean a bit better and add sensors and modes, useful, but the heads are the big lifetime cost. A mid-range brush with affordable heads gives most of the benefit for far less. Check head cost before buying.
For many Oral-B and budget brushes, yes, at a fraction of branded prices, though fit varies. Sonicare and Oral-B iO use patented connectors with few cheap options, so you are more locked in.
