Pack of 2 brush heads for Philips Sonicare electric toothbrush.

One bristle type seems better than the other.

I'm not sure what the difference between the black bristles and the white and blue bristles is, but the former seems to be much better quality. I used the head with the white bristles first, and it shed several bristles the first two times I used it. That wasn't a big deal by itself. Those bristles were also quite rough on my gums. The wooden part of the toothbrush head also popped off the plastic part that secures it to the motor arm, rendering that head useless, after only 4 uses. The other head hasn't shed any bristles yet, is still intact 2 weeks in, and has struck an extremely good balance between cleaning teeth and gums while not being so rough on the gums. My teeth feel like I've just come back from a dental cleaning each time I use this brush head. I'm not sure if the first head was just a fluke, but if the white-bristle head is consistently going to have more shedding bristles, harsher on the gums, longevity issues, etc. I'd rather just buy two of the heads with the black bristles. It somewhat defeats the purpose of reducing waste if I only want to use one of the two heads in the package.

not my style. I thought the heads would be the same size as the normal philips sonicare heads. They are larger. The bristles are also much longer and softer than the normal heads. The bristles tend to fall out while brushing so be prepared for that. If youre okay with the taste of wood then that shouldnt bother you. Worth a try for how cheap they are. Took over a week to get to me in B.C.

Prompt service. Using the subscription service. Recyclable packaging. Product fits toothbrush well. Bristles are high quality. Best of all its a Canadian product.
