As a dental hygienist, I am telling you…the bristles are definitely NOT soft as advertised. They are extremely hard and coupled by the power from the electric toothbrush these have the potential to be abrasive and wear down your enamel layer. Once your enamel is worn down, it is unable to repair itself. Definitely not worth the risk, folks. Anyone in the dental field will tell you- soft bristles only! Very disappointed that Phillips would distribute a product like this

I recently purchased the Philips Sonic Toothbrush and wanted extra brushes. Found these for the best price at Sams, so I ordered them online. They were delivered quickly and they work just fine. Nice soft bristles. I am still getting used to the electric toothbrush, but I do feel that my teeth are cleaner!

Well worth the money. Best bang for your buck!

Takes advantage of all available features of the Phillips 6100 rechargeable handle.

Has an excellent reminder to replace

Great product, easy to use, easy to replace the heads on these sonic instruments.

I feel that they are a little pricey but the product is good

Good quality but absolutely ridiculously expensive. Will probably check out their competitors in the next year or so

The electric toothbrushes from Philips are simply the best around. These refills came at the best price around

Works well and always gets compliments from my dental hygienist about how clean my teeth are during check ups.
