Electric Toothbrush Replacement Brush Heads - 4Pcs Travel Toothbrush Medium Adult Electric Toothbrush Head Replacements - Soft Bristles Spin Brush Heads Replacement Toothbrush Heads For 3733 4732 4734

These are very hard to find - so glad Amazon had them. They are just what my toothbrush needed. Thanks!

The cost is bit high. For the cost of each 2 brush refill, I could buy a new power refillable brush

I don't believe these are real Oral B heads. I think they are a cheap knock off. Every time we use our toothbrushes we get nylon bristles in our mouths. It's gross! At the rate they are falling apart, the heads we just put on will be bald in a few weeks. Horrible product. I only ordered online because I couldn't find them in the store. They were out of stock for over a month and we needed new heads.
