Which electric toothbrush is right for you?

If you're trying to figure out which electric toothbrush to buy, here's what matters most:

Consider your sensitivity level. If you have sensitive teeth or gums, look for brushes with pressure sensors and multiple intensity settings. Models like the FOREO ISSA 3 with silicone bristles or the Laifen Wave with app-controlled intensity are gentler options that won't leave you wincing during your morning routine.

Think about smart features. Decide how much tech you actually want. Basic models focus on cleaning performance, while smart brushes like the Oral-B iO series offer real-time feedback, app connectivity, and brushing tracking. If you're someone who loves data and wants guidance on technique, invest in the smart features. If you just want clean teeth, save your money.

Budget for long-term costs. Don't just look at the upfront price — replacement heads can add up quickly. Some brands like Quip charge $12 per head, while others are more affordable. Factor in how often you'll need replacements (typically every 3 months) when choosing your brush, especially if you're buying for multiple family members.
