    Is this rotating or vibrating as heard vibrating isn't that much better than manual

    • scrimshaw on 09/09/2025 - 13:25

      Philips Sonicare brushes vibrate, while Oral-B brushes rotate.

      Dentist also said that the vibrating is far less effective than the rotating, I'm looking to switch to an Oral-B brush now.

      • easternculture on 09/09/2025 - 13:37

        The rotation of oral b also helps massage the gum

        Massaging your gums stimulates blood flow, delivering more oxygen to the tissues, which strengthens them, helps fight off bacteria, and reduces inflammation. It can also loosen and remove plaque and food debris, strengthening gum tissue and preventing gum recession. Regular gum massage can also help relieve jaw tension, reduce stress, improve oral hygiene, and potentially speed up healing after dental procedures.

        Oral-B don't rotate, this is a common misconception. Break one brush head to see what is inside. This is the same vibration that is limited to particular angles only.

        See how modern brushes work, they actually make swiping and vibrating movements, while "rotation" is not massively popular outside of Oral-B.

      rotating is better, sonic and water floss, though fancy, aren't strong enough.
      i changed back to rotating and manual floss after my dentist said rotating was better, and notice a lot less plaque at 6 monthly cleans

      • easternculture on 09/09/2025 - 16:51

        Or you could try natural toothbrush (miswak) which is proven as effective

        • bargsbargsbargs on 09/09/2025 - 17:26

          Where do you buy yours from? Are there australian sourced alternatives?

          • easternculture on 09/09/2025 - 22:53

            @bargsbargsbargs: I get them from overseas when i travel for 95% off the price they sell here

            I like to choose mine individually.

            But plenty of sellers on ebay and amazon

            I do 10 min oil pulling with 1 tble spoon olive oil and a few drops of zamzam water before using miswak in the am.

            I still use an electric toothbrush daily though with a fluoride free toothpaste

  • UncommonName on 09/09/2025 - 13:33

          Its a vibrating machine, so cant guarantee it was used just in the mouth.

      As mentioned in description Big W has a clearance on non-moving stock. Amazon has a price matching algorithm.

      • UncommonName on 09/09/2025 - 17:59

        Why it's not selling at Big w? Is it not a good brush?

        • Username Taken on 09/09/2025 - 19:15

          Because people don't go to Big W to buy an electric toothbrush

          • Ozzster on 09/09/2025 - 21:07

    Wonder why Phillips doesn't do rotating heads? Is it some wierd patent issue?

  • John Doh on 09/09/2025 - 14:09

    For just a little more, there are better rated ones with many free heads, wonder how this stacks up? Anybody used one of these?

      Difference is gonna be in the longevity of the battery. Replacement heads are cheap.

    Whats the general consensus on Sonic vs Rotating heads?

    • tdonovic on 09/09/2025 - 14:59

      I much prefer the oscillating head to the rotating. My teeth feel much cleaner afterwards

    • cornflakes on 09/09/2025 - 15:38

      Call me old school, but I just like simple straight head. Don't mind a bit of drool.

    • scupper on 09/09/2025 - 18:35

      I recommend Sonic.
      Rotating can get moldy if it doesn't dry. The batteries don't last a week, they're probably still using NIMH and not lithium. If you have sensitive gums, the rotating bristles are harsher when they hit and would probably lead to gum recession. Sonic is more precise so easier to control how much the gum is being hit. Also the pointed end of the brush head for Sonic can reach into spaces the rounded one for rotating can't.

    • unison on 09/09/2025 - 22:03

      Had both entry level rotating Oral-Bs and this Philips one. Build quality is a lot nicer with the Philips, had an Oral-B one where the rubber button wore out and broke the water-resistance. The Philips also charges with USB and has a li-ion battery that lasts 2 weeks. As to mechanical vs sonic, you get passionate people argue for either side. For me the biggest difference is the noise and vibration in your head that is a lot more comfortable with a sonic toothbrush.

  • ImaginarySoldier on 09/09/2025 - 15:38

    I can't vouch for this model in particular but we switched from Oral B after many years to Sonicare and our experience has been very positive.

    The dentist said my teeth are much cleaner after a year of use. The smaller head of the sonicare means you can get into tighter spaces like the corners of the your mouth and the gums much more effectively.

    The head of the sonicare toothbrush is fully closed when brushing so no liquids get inside. The open design of the oral B head get dirty very quickly as it does not not dry easily.The only downside was no brush identifying rings like the oral B. Easily fixed with a quick 3d print.

    The quality of the brush body is also much better. The Oral Bs would always collect a lot of gunk and the rubber would degrade very quickly, even with expensive models.

    We are greatly satisfied with the product and I believe it was with the premium.

    • Hopalong Gosling on 09/09/2025 - 18:13

      +1 - I have the Oral B and am thinking of changing to Philips once I work through the bulk pack of brush heads I have.

      The Oral B gets all gunked up because of the open head - the way I prevent this is by rinsing with hot water and then drying it out by shoving paper towel/toilet paper between the head and the body.

      Bit of a pain.

      • Richardc on 09/09/2025 - 19:51

        Just unplug it, rinse and let it air dry every time.

      • Pusdi on 09/09/2025 - 22:20

    We had two of these, the button doesn't last, torn/leaking in about a year or so, then water went in and the destroys the circuit board, it switches on by itself and cannot be controlled by pressing the button. YMMV
    But given the price, still a bargain.

    Had an older Sonicare brush still going strong though, over 5 years old.

  • makeyouryear on 09/09/2025 - 21:35

    Oral B iO series 3. Cheapest brush with the same fancy magnetic drive as in their $500 model. About 10dB quieter than the old style heads, no rubber on the bottom of the handle to foul and even works with old Oral B chargers. All the smart features you actually need with no need for an app - timers, brush replacement light (resettable) and pressure feedback lights for both too hard and too soft. I've used it once, definitely a different sound and feel and so far I like it. One big con is the price of replacement heads, around twice the price.

    Cheapest retail is $89 at David Jones, currently additional 10% off until midnight. I just price matched the sale price at Chemist Warehouse. They have it listed at $180 so the cashier was definitely sweating and double checking the $70.11 I paid.

    • SevenSmurfs on 09/09/2025 - 22:35

      Was keen on an iO3 but $20 for this Sonicare with significant cheaper replacement heads…
