Finally got me to floss — dentist is thrilled

Verified
By Jason M.Owned 8 monthsbeginner user2025-10-30

Pros

  • +I actually floss now — first time in my adult life
  • +Teeth and gums are healthier than ever
  • +ADA accepted gives me confidence

Cons

  • -First two weeks were a watery disaster
  • -Brush head feels big in my mouth

I'm 34 years old and have never been a flosser. I'd buy string floss, use it twice, and throw it in a drawer. This device changed everything. The 'Both' mode lets me brush and floss simultaneously in my normal 2-minute routine. My dentist, who had been lecturing me for years about gum disease risk, was visibly shocked at my last checkup. Bleeding during probing went from 12 sites to 2. Yes, the first two weeks were messy — water everywhere. But once I learned to lean over the sink with lips mostly closed, it became second nature. This literally saved my gums.

Jack of all trades, master of none

Verified
By Margaret T.Owned 4 monthsexpert user2026-01-15

Pros

  • +Convenient concept
  • +Water flossing portion works well

Cons

  • -Brushing is mediocre compared to my old Sonicare
  • -Brush head is too bulky
  • -Takes up too much counter space

I wanted the convenience of one device but the compromises are too significant. The brushing is noticeably weaker than my Sonicare DiamondClean. The brush head is so large that I struggle to reach my wisdom teeth. The water flossing component actually works well — on par with a standalone Waterpik. But here's the math: a Sonicare 4100 ($50) + Waterpik Aquarius ($70) = $120 for better performance than this $150 combo device. I've gone back to separate devices and given the Sonic-Fusion to my teenager who actually likes the simplicity.

Game changer with braces

Verified
By Lauren H.Owned 6 monthsbeginner user2026-02-22

Pros

  • +Gets around braces brackets perfectly
  • +Removes food that string floss can't reach
  • +Much faster than threading floss through wires

Cons

  • -Messy at first
  • -Reservoir is small — need to refill once per session

I got braces at 28 and brushing/flossing became a 15-minute ordeal. Threading floss under wires, trying to reach around brackets — it was miserable. The Sonic-Fusion cut my oral care routine to 4 minutes. The water jet blasts food out from around brackets that bristles and string floss can't reach. My orthodontist said my oral hygiene is better than 90% of his adult patients. The reservoir runs out before I finish my lower arch, so I do one refill per session. Small price for the convenience.
