What's great about it: Replacement Bristle Heads - Strong Bristles
I can't stand it when I see people using the same brush for years. I get these packs for replacement heads for every 2-3 months, when I feel it's appropriate to replace my old bristles. For a 4 pack, with each one lasting 2-3 months, I'm pretty much set for the year. Great value too. If you think about it... this is the only part of the brush you should really care about because it's the only thing cleaning your mouth. For the price compared to the whole set (handle part), this is a good buy. By replacing old brush heads with new replacement heads, you'll keep your teeth white and squeaky clean!
