Is this compatible with the Oral-B Precision 4000?

I can't answer your question definitively (I'd take that up with the company on their 800 line, which I called to get an explanation on the differences between the different models of brushes -- and I found the person who took my call at their center to be helpful), but I can tell you that the brush-heads I had with my first 3000 fit on the 7000, even though the names I thought those brushes don't match with anything that they sell now. In other words, I think the answer to your question is "yes, they're all interchangeable," but I'd get that answer directly from the company.

I looked it up on Amazon....under specs for the 231 it does not list the 4000 series as compatible. Can always give it a try and return it if it doesn't work.

My ASSUMPTION is that it would. Most, if not all, Braun Oral-B charges seem to have the same type of charging appearance. If the bottom of your toothbrush (and the projection of your charger) look similar to the letter "D", I believe it will work.

I have the old oral B sonic vitality and they fit perfectly. Don't know what "type" it is.

Its been 5 months but others might have similiar question. Probably will work. This works with the following: Oral-B Triumph ProfessionalCare 9000 series replacement power toothbrush smart charger. Models/Types: 3731, 3738 & 3745 You find the Model/Type on the bottom of the toothbrush

Only Phillips can tell you for sure about this compatibility, but I was using the Pro-results brush, and the Diamnond-Clean brush head fit that handle just fine. Hard to keep up with all the various model numbers Phillips has for these "tooth maintenance" systems! One Phillips site listed Diamond-Clean on a 6921 model, so if handle end is similar to 6930 there's a good chance it will fit. If it does not fit, I expect that Amazon would exchange it for you (and Phillips has a 90 day "like it or your money back" policy, too).

Mine doesn't have the model no. either. I would imagine this one works for most Sonicare.

You can use toothbrush Sonicare HX6023/64 or HX6013/64 for Sonicare HX6023/64 Sonicare FLEXCAREPLUS

I am not sure, go to Phillips Sonicare and check there, it will tell you what works with what.

Sorry, I am not familiar with the Oral B professional care 5000. Have never used it.

I am not familiar with the models above. But, I have found that they have made this waterpik so that their own products can be used with any of the models. I think the mechanism where the pics plug in is most likely standard among the products. Look up the cs number and call them. AK

I do not know what model these fit, but my oral B heads looked exactly like these generic heads. The quality of these generic heads is poor, the inside parts break easily. My Oral B heads never broke and lasted forever, although they cost more.

As far as I know they are interchangeable with Waterpik devices, so yes they should fit! Hope this helps

if i were you, i'd go to the oral-b web site or the braun web site. and if need be, you could call either company (since braun makes the innards) customer service dept. sorry, i personally don't have an answer for you.

I have the oral-B SONIC COMPLETE. Do NOT know about the 4729. I hope this helps.

I don't know the answer to your question. Have you tried contacting Oral-B customer service?

Yes it is. I was a little worried too that it wouldn't be the right thing, but it was. The box they come in says "OB Indic 35 Sft" on the end -- Oral-B Indicator 35 Soft.
