I have a very old Oral B electric toothbrush and up to now have been buying replacement heads online. However the last batch came from Wuhan so I threw them away. I am going to get the proper Oral B replacement heads at Boots... but there is so much choice, would all the different types fit my toothbrush??
They would all fit your toothbrush I think, but some of the brush heads seem very large to me. I had a job to find the most basic brush heads, which I like, but I did eventually get them in Boots. I have the same problem trying to find basic Sensodyne toothpaste.
Short answer....yes.
(However, Oral B did make a "sonic" brush - not sure if they still do - and those require different heads.) But, all "oscillating" brushes and heads are interchangeable.
My sonic toothbrush heads are proving rare and expensive these days. If they don't continue to support products why should I trust enough to buy them ?
