Braun Oral-B Smart Guide Display Versions

In this article we explain the different models and sub-versions of each of the Braun Oral-B wireless Smart Guide displays, to complement our Smart Guide repair page.

The Smart Guide display units were supplied with various models of Braun Oral-B electric toothbrush and allow the user to keep track of their brushing progress throughout each brushing session. Two main models of Smart Guide exist, the squarer Type 3741 and the more rounded Type 3742. Each type has several variants and offers compatibility with different models of toothbrush.

Which Smart Guide Do I Have?

If you are looking for a replacement Braun Oral-B Smart Guide unit for your toothbrush because yours is beyond repair or has been lost then use the information below to see which one you need, where to buy one and how to get pair it with your toothbrush.

Type 3741

Smart-Guide-3741-Braun-Oral-BThe Type 3741 Smart Guide from Braun Oral-B is the original model and comes in at least 4 different sub-versions, each with slightly different icons and features. Unfortunately the different versions are not interoperable so if you are looking for a replacement Smart Guide that is compatible with your electric toothbrush use our guide below to determine which version of 3741 Smart Guide you have or need. The 3741 Smart Guide is powered by two AA size batteries and we recommend that only Alkaline batteries are used.

Pulsonic version

Smart-Guide-3741-Pulsonic-VersionThis version of the Type 3741 Smart Guide was supplied with the Pulsonic range of toothbrushes and only works with Pulsonic toothbrushes marked Type 3723 on the handle.

The Pulsonic Smart Guide displays a diagram of a toothbrush with a tall narrow brush head attached. It shows no stars on the screen and the colour of the rubber seal on the back of the Smart Guide is unknown at present. Please leave a comment below if you have one of these and can tell us which colour the seal is. Once brushing is completed it will show a smiling face 🙂

Up to two separate Pulsonic toothbrushes can be synchronized with the Pulsonic Smart Guide so see the ‘Pairing’ section lower down for instructions.

No Star Triumph version

Smart-Guide-3741-Triumph-Version-No-StarsThis version of the Type 3741 Smart Guide was supplied with some of the original Triumph v1 range of electric toothbrushes and will only work with Braun Oral-B toothbrushes marked with Type numbers 3738 marked on the bottom of the handle.

The No Star Triumph Smart Guide displays a diagram of a toothbrush with a round brush head attached. It shows no stars on the screen and the rubber seal on the back of the Smart Guide is blue as shown in the photo below:

Up to two separate Type 3738 toothbrushes can be synchronized with the No Star Triumph Smart Guide so see the ‘Pairing’ section lower down for instructions.

5 Star version

Smart-Guide-3741-5-Star-VersionThe 5 star version of the Type 3741 Smart Guide shows 5 stars at the bottom of the screen and has a grey rubber seal around the battery compartment.

We’re not currently sure which Type numbers of toothbrush it was supplied with so do let us know in the comments below which toothbrush type number your 5 star Smart Guide works with. Up to two separate toothbrushes can be paired with the SmartGuide so see our synchronizing instructions lower down the page for how to do this.

4 Star version

Smart-Guide-3741-4-Star-VersionThe 4 star version is believed to be the last version of the Type 3741 Smart Guide and was supplied with the Type 3762 toothbrush which is one of the Triumph v2 range of toothbrushes. This Smart Guide shows 4 stars at the bottom of the screen and has a grey rubber seal on the back, as shown in the photo below.

It is possible that the 4 star Type 3741 Smart Guide can be substituted with version A of the 3742 Smart Guide as that display was also supplied with the Type 3762 Triumph toothbrush. Two separate toothbrushes can be paired with this Smart Guide at once so see our synchronizing instructions lower down the page for how to do this.

Type 3742

Smart-Guide-3742-Braun-Oral-BThe Type 3742 Smart Guide from Braun Oral-B is the newest model and comes in at least 2 different versions. Unfortunately the different versions are not interoperable so if you are looking for a replacement Smart Guide to work with your electric toothbrush use our guide below to determine which version of 3742 Smart Guide you have. Available in white and silver, this Smart Guide is powered by two AAA size batteries and we recommend that only Alkaline batteries are used, not zinc ones.

Version A

Version A of the Type 3742 Smart Guide has a letter A at the end of the string of numbers marked inside the battery compartment on the ridge between the two batteries. This version was supplied with Oral-B toothbrushes marked with Type 3762 on the bottom of the handle.

Version B / Version 2.1

Version B of the Type 3742 Smart Guide has a letter B at the end of the string of numbers marked inside the battery compartment on the ridge between the two batteries.

Only available in white, version B of the 3742 is also known as the 2.1 version and will work with the Genius/Smart range of toothbrushes marked with Type 3765 on the toothbrush handle. You might need to enable the Smart Guide functionality on the toothbrush itself via the smartphone app before the brush will synchronize with the Smart Guide.

Where to Buy a Replacement Smart Guide

The only Smart Guide units still available brand new are of the 3742 type. For a 3741 you will end up buying a pre-owned one. If you find that you can’t repair your current Smart Guide then the best place to find a replacement new or used Smart Guide is through the listings linked to below on eBay. Make sure you choose one of the same variant as your current Smart Guide as the different sub-versions are not interoperable and the wrong variant will not work with your toothbrush.

Don’t forget that you might need to ‘pair’ or synchronize your new SmartGuide with your toothbrush when it arrives. See the next section for synchronizing instructions.

Synchronizing your Smart Guide with your Toothbrush (Pairing)

Your Smart Guide can be synchronized (also called pairing or programming) to work with one or two Braun Oral-B toothbrushes at the same time, as long as both these brushes are of the same Type number.

Setup & Clock

To power up your SmartGuide slide open the battery cover on the back and insert two fresh Alkaline batteries (AA size for the Type 3741, AAA size for the Type 3742 SmartGuide). The clock display should start flashing ’12:00′.

Press and hold the ‘set’ button inside the battery compartment until ’12h’ is flashing in the display. This means that time will be displayed in the 12-hour format. If you would prefer 24-hour time format press the  ‘h/min’ button once so that ’24h’ is displayed. Press ‘set’ to save the setting.

The hours digits should now be flashing. Keep pressing the ‘h/min’ button until the correct hour is showing and press ‘set’ to save the setting.

The minutes digits should now be flashing. Keep pressing the ‘h/min’ button until the correct minute is showing and press ‘set’ to save the setting.

Synchronizing

  • Open the battery compartment of your Smart Guide and hold down the ‘h/min’ button for 3 seconds until the display starts flashing ‘L ‐ ‐ ‐’
  • Switch on your toothbrush for a few seconds until the SmartGuide displays ‘L ‐ 1 ‐’
  • Switch off your toothbrush
  • If you have a second matching toothbrush to pair with the SmartGuide switch it on now and let it run for a few seconds until the SmartGuide displays ‘Full’
  • You can exit the pairing process by pressing either button inside the battery compartment.

Some toothbrushes have the facility to turn off radio transmission so if this has been used the toothbrush will be unable to pair with the Smart Guide.

  1. Thanks very much for the instructions: now working well

  2. My toothbrush died, but since I already have the case, I’m looking to find the cheapest model with SmartGuide support. Do you know if models that don’t have SmartGuide, support it if used near one?

    1. What is the Type number marked on your toothbrush handle?

  3. I have a Braun Oral-B Type 3709 toothbrush that needs a new battery.
    Although in my 80th year I am capable of all DIY in my home and would appreciate your guidance in getting inside the 3709 as there seems to be some resistance to unscrew the base.
    Once I’m in I will order the necessary battery.

    1. Hello John,
      Your Type 3709 Vitality toothbrush opens at the top rather than at the bottom. We have a photographic guide to opening the toothbrush and replacing the battery on our website here.

  4. Hello,
    My Braun Oral-B Triumph v2 finally died (it sounded like a gear stripped while I was brushing). I really like the Smart Guide (I have the 4 star version of the 3741). I tried the app and it sucks using your phone in the bathroom. Does anyone know if there are any current brushes that work with this Smart Guide (3741). I have read elsewhere that the 3741 does not work with the newer brushes, but the 3742 does.
    Should I just skip the 3741 and get a 3742 and a new(er) brush?
    Any help would be appreciated!

    1. Hi Alan, The Oral-B v2 Triumph toothbrushes are still available as ‘SmartSeries’ brushes from some suppliers so you can replace like-for-like. There is some further information on our ‘which new toothbrush’ page here.

      1. Thanks for the quick reply.
        Thanks for the link.
        I am considering the Oral-B Pro 7000 from Amazon USA (I live in the US).

  5. Hi,

    I was wondering, is there any way one can make a 3742 A Smart Guide work with a Genius 8000 and if not, what exactly is the difference between the models? Thanks!

  6. Hi,

    Could you elaborate more on the remark “You might need to enable the Smart Guide functionality on the toothbrush itself via the smartphone app before the brush will synchronize with the Smart Guide.” After a battery replacement am I not able to pair my toothbrush with the Smart Guide anymore. Thanks

    1. If you have the Oral B app installed on your smartphone you can use the app to configure different features on the toothbrush. One of these features is to enable SmartGuide communication between toothbrush and SmartGuide. This only works for certain models of toothbrush though. What is the 4-digit Type number marked on your toothbrush?

      1. I have 2 toothbrushes of Type 3764. They both used to be synchronised with the SmartGuide however currently only 1 is recognised and the other one doesn’t seem to connect anymore to the SmartGuide after a battery replacement. Radio transmission is activated on both toothbrushes.

        1. Have you tried resynchronising the SmartGuide with your toothbrush?
