Dental answers, made clearer
Compare toothbrushes, floss, interdental brushes, mouthwash and other cleaning tools so you can use them safely and effectively.
Studies generally show electric toothbrushes remove plaque slightly more effectively, largely because their consistent motion compensates for uneven brushing technique. That said, a manual toothbrush used correctly, at the right angle for two minutes twice a day, can still achieve very similar results.
Read the answerA water flosser can be a helpful alternative for people who struggle with string floss, such as those with braces or limited dexterity, and it does a good job of flushing out debris. However, it's not universally proven to be as effective at physically disrupting plaque along the gumline as traditional flossing, so many dentists recommend it as a supplement rather than a full replacement.

They're often recommended alongside, not instead of, regular brushing and flossing.

A smaller, more maneuverable head generally allows for more thorough cleaning, especially for children or people with smaller mouths.
