Philips SonicareOptimal Gum Care Replacement Toothbrush Heads, HX9034/65, BrushSync™ Technology, White 4-pk

Works great, just got theses replacements for my electronic toothbrush.

Exactly the quality I expected. They are soft enough yet do a good job cleaning.

Great price and fits my electric bush.

These brush heads are the real deal, and the price is excellent. It's really nice to occasionally get a great product for a fair price. I'll buy again when the time comes.

the bristles are soft and i like it that way as I do not want it too hard. the only thing i do not like about it is the curved shaped the bristles form. i like the shape of the plaque removal one (C2 brush). does its job for my slightly sensitive teeth. it fits the sonicare 4300 series.

These are my new favorite brush heads after using the “sensitive” ones for years. The end bristles seem gimmicky but they clean much better, they do feel soft and I just got back from the dentist and there was almost no tartar buildup for them to scrape. The hygienist was almost baffled there was so little to do. These also have the brush sync which I haven’t tried yet but so far very impressed and will buy these exclusively from now on

Great replacement heads for my Sonicare. They clean gently but thoroughly and are perfect for sensitive gums. I notice a difference in how fresh my mouth feels after switching to these.

The thing I noticed after using this particular Sonicare brush head is that my teeth have only felt this clean after seeing a dentist and having them cleaned. I also use the Massage function on my Sonicare and feel this particular brush design does a better job of helping me maintain healthy gums. I changed my toothpaste to Mouthology 10% Nano Hydroxyapatite Toothpaste at the same time but still think it was the brush head that made the difference or a combination of the two. I would recommend this toothpaste as well.
