More Oral-B Toothbrushes Under $100: iO2 and Pro 1000
Best for First-Time Electric Toothbrush Users: Oral-B iO2
The Oral-B iO2 is a simple, gentle way to switch from a manual toothbrush to an Oral-B iO electric toothbrush. It offers a one-button brushing experience, Sensitive and Super Sensitive modes, and starts on Super Sensitive mode by default to help ease the transition to electric brushing. It also uses Oral-B iO’s dentist-inspired round brush head, oscillating-rotating technology, and gentle micro-vibrations.
Choose Oral-B iO2 if you’re new to electric brushing or transitioning from a manual brush and want a gentle Oral-B iO clean that feels easy to start.
Basic Rechargeable Option: Oral-B Pro 1000
The Oral-B Pro 1000 is a basic rechargeable Oral-B brush with classic oscillating-rotating and pulsating cleaning action. It is a straightforward option for people who want a simple electric toothbrush at a lower price point.
Choose Oral-B Pro 1000 if: $50 is a firm ceiling or you want a simple rechargeable Oral-B brush.
Bottom Line: The Best Oral-B Electric Toothbrush Under $100
Among Oral-B’s sub-$100 models, our pick is the iO3 or iO4 (~$90–$100). They offer Oral-B iO cleaning technology, a dentist-inspired round brush head, Visible Pressure Sensor feedback that helps show whether you are brushing with too little, the right amount, or too much pressure, and a celebration when you reach the dentist-recommended 2-minute mark.
If you’re switching from a manual toothbrush or want the gentlest entry into Oral-B iO, choose Oral-B iO2. Pro 1000 is still a strong basic rechargeable option, but for about $15 more, iO2 is the better fit if you want Oral-B iO cleaning technology and a smoother transition to electric brushing.
