These heads keep their shape for about a month, which seems appropriate under normal wear and tear of brushing. The beauty of them is that I can snap the heads off the stem of the toothbrush easily and change out without changing batteries in the toothbrush handles for months. The bristles are firm and hold their shape well. My teeth get very clean using this brush and only this brush head. The batteries last forever even if the heads don't. So keeping a lot of these in stock helps to keep a fresh, dry head on the matching stem. They aren't cheap but they are economical. In other words, they don't fall apart like some cheap toothbrush heads do but they are worth the moderate price. And whose teeth aren't deserving of good care?

Ive used these brush heads for over a year and changed them every 3 months as recommended. The head is easy to change and is effective for 3 months. Ive not had a cavity for over a year and can attribute this to the Oral B heads. I will continue to use them.

These brush heads were difficult to find. I finally found them on ebay. I have an old model, a discontinued Crossaction electric toothbrush and after calling Oral-b,I finally figured it out and was able to find these brush heads that go with it. I love ebay!
