  • $79.20 + Delivery (Free C&C) @ The Good Guys eBay, using code PGGUY

    Good if you have eBay Gift Cards.

  • Sorry to say… good luck with 2wks of brushing, i do not think you will get that.. we have the 9000 and its no where near that, plus takes all night to charge.

    In saying that, we are happy with it and the charging travel case that our came with it.

    • Some modes use far less power than the one that is just on full power for 100%.

    • Mines over 5 years old and is lucky to go for 3 days.

      • The Oral-B Smart 4 4000 now comes with a new upgraded lithium ion battery. This is a vast improvement over the “old” Oral-B Smart Series 4000 whose Nickel Hydride battery only lasted 1 week.

    • I've had the 4000 for 1.5 years, still lasts 2 weeks for me on full power and takes roughly 10 hours to charge. Battery may die eventually but I'm happy with this so far.

    • I have a 3000. 4yrs now. If one person brushes, and the next wants to brush, you can feel the power is lower and it's not worth even trying unless you want to spend twice as long to brush. I'm sure it'll "move" for a week, but I don't want to spend 10min to brush.

    • I've had the smart 4 for almost a year now, I'd say 2 weeks is about right, maybe just under.

  • I'm looking for a new tooth brush and can't decide whether to get this for $79 or get the 100 or 500 for $35 or $50, any opinions or advice?

    • Avoid the Oral-B Pro 100, since it has NiMH Battery.

      If you want bluetooth features get the Smart 4 4000, if you don't need the features get the Pro 500.

      IMO, pay a bit more and get the Smart 4 4000 .

    • Get the 4000, the 100 doesn't have the 3D actions (oscillates, rotates and pulsates) and the 500 doesn't have the 2 min timer. In addition, don't believe 100/500 has lithium battery (can't seem to find much info online) which is great as lithium battery lasts longer.

      The few points are worth the $79 investment.

      • the 500 doesn't have the 2 min timer. In addition, don't believe 100/500 has lithium battery (can't seem to find much info online) which is great as lithium battery lasts longer.

        According to Shavershop, the Pro 500 has a built-in 2 minute timer and lithium-ion battery.

    • Get this one Oral B 3D toothbrush and use eneloops ;)

  • Get an Oclean X. Absolutely amazing brush. By far the best I've had

  • Costco is having a discount for dual oral b toothbrush smart 5 5000, with $144.99. This one is cheaper, and I think it is better.


    • That is a good deal if someone needs two and has Costco membership, though I think there is hardly any difference between the two models. The 5000 has an extra couple of cleaning modes, but not much else I believe.

    • The dual toothbrush packs only come with one charger.

  • So above this model, you go to the 7000, then the genius 8000 and genius 9000? Or an I missing some in the gaps?

    • There's a 5000 and 6000 as well. The 5000 is pushed by Oral B to dentists as their base Smart model (seriously, there's no mention of the 4000 on the "suggestion" slips they give us to give to patients), but the 4000 is the model I recommend to my patients.

      EDIT: IIRC the 8000 and 9000 are almost identical (carry case is better in the 9000, which also has the tongue cleaning mode), and there's a new IQ model out too.

      • Any tips on the best way to clean your tongue, or keep it clean? After cleaning my teeth with an Oral B electric toothbrush, I scrub my tongue with a manual toothbrush. Not a pleasant experience, but for me, a clean tongue is part of oral hygiene.

        • Eat more roughage. Dairy tends to create a layer, so for this and a variety of other reasons it may be ideal to reduce consumption. Tongue scrapers abound at many stores. Hydrate well.

        • Why not use your electric toothbrush on your tongue?

        • A tongue scraper is best! I have one of the cheap ones from a 100yen shop in Japan and it works a treat. After you use one and see the results, you will never bother with the toothbrush on your tongue again.

      • So hard to tell what the differences are between the models still. Why would i look at the 5000 and 7000 above the 4000?

        • Extra brushing modes are about all you get in the higher models.

          I had the 9000 because professional discounts brought it to a comparable amount, and it had a charging carry case. I recently got my paws on the new IQ model, and it doesn't require the phone to be in the mirror mount to detect positioning.

          I tell my patients to buy the 4000, unless they can find the 9000 on sale for less than $140 at which point they should consider if they need that carry case.

  • If anyone is wondering if they should get an electric toothbrush

    You should absolutely get one.

    • Reason?

      • Much better cleaning, saves alot of time and effort.

        • Yes, in most people’s hands a quality electric toothbrush will do a better job at cleaning off the plaque (number one teeth enemy), but is also less damaging to the gums. Although some gum recession is inevitable as you age, it’s something you want to limit as much as possible as it makes your teeth more susceptible to various problems, including tooth loss.

      • Ok, with a bit of a exaggeration
        You won't see a dentist after you switch.

        • You seriously don't see a dentist?

        • I don't after making the switch and ensuring good dental hygiene. I brush twice for the recommended 2 mins on these electric toothbrushes and floss each and everytime, daily. Haven't been to the dentist in the last 8 years.

  • I have an oral b type 3756. I think it's the Professional Care 3000.
    It has 3D Action 40,000 in-and-out pulsations and 8,800 back-and-forth oscillations per minute
    I believe these specs are identical for all the pro models and I don't get why you'd care for more.

    But I'm looking for another one with Pressure sensor light for the kids. They got one of those starter $49 ones and it's crap, so slow they just can't clean properly.
    What is worth getting?

    Btw we don't understand or use the 3-modes thing.

    • I am not sure if this type is recommended for kids considering their gum still grow and if the toothbrush is too powerful, it may actually dislocate the tooth.

      • aren't they the ssame but for rotations?
        I thought the light to tell them not to press too hard is better

  • Does this one come with a case? The picture that’s shown for this same model on shaver shop has a case in it. This one doesn’t look like it’s included.

  • How long will this deal last?

  • What is the best electric toothbrush with a round head at the best price. Any OzB favourites? I'd like to spend less than this price if possible.

    • This is it. This is the model I recommend to my patients because it's the cheapest model that has everything you need. Normally it's $99, so for $79 it's a fantastic price.

  • Also Shopback says "up to 12% off"

  • Got one - does this come with 2 heads (for 2 people) or do I need to buy something else?

  • I still can't really work out what this is missing compared to the 5000, then 7000.

    • Not much except for an extra couple of cleaning modes which you will never use… I think the others may also come with a free travel case as standard.

  • Awesome. Got it for $59 using my McDonald's Monopoly $20 Amazon code.

  • I grabbed the 7000 on sale for this price. Just recently bought an X3, got one for my mum too who absolutely loves it VS Oral-B Toothbrushes.

  • Thanks a mill.. got it for $59. Tx to the $20 win from maccas lol.

  • Any reason to get this instead of genius 8000 dual handles ($200) / Genius 9000 ($269)?

    I know it comes with single charger but I have a spare charger here.

  • me three. sigh. my oralb 5 series is on its last legs. i do miss the old models that come with an actual timer device that doubles up as a clock too. Any recommenations for that?

    • Mine still going strong, and I love timer too. It's got a clock and timer, so that's great. Not so great is their advertising the speed of it, when in fact as soon as you've done one brushing it slows down. So it is misleading. At the end, you end up with speed like what those cheap ones have. And it's not the battery that is old. It is by design. You'd think in 21 century they'd do better, but even if you spend more, you get less.

      I'll use for as long as it works, and if battery needs changing, buy another and replace. If you don't know how, just watch YouTube videos. It's easy job. Shouldn't put a lithium battery as the charger itself is not for charging them.

  • Cancelled. I'm heart/tooth broken!

  • I think anyone can still get one from JB HIFI or chemist warehouse through price match.
    I just bought one in CWH today for $74.9.

  • Just got an email saying its out of stock and it will be cancelled… But still shows in stock WTF… So I'm assuming the $20 voucher I used from my macca's will now be invalid.

  • It's showing as $79 again, so for those of us who got the email saying order cancelled, give it another go.


  • Showing as $99 now sold by Amazon. I contacted Live Chat and they give me a $20 promo code due to the cancelled order. Hoping to see it drop down to $79 then will try re-order

  • Must have been one of the early ones to order, mine was delivered yesterday.

  • Yeah I got mine no problems. So much more powerful than my previous 500 model
