Oral-B 敏感與牙齦護理 X-Filament 替換刷頭，1 入

My gums used to bleed with my old brush head, but these x-filament bristles feel so much softer while still getting the job done. Two weeks in and my dentist actually commented on the improvement.

The ultrathin bristles are the real deal—they slide between my teeth without that harsh scraping feeling I got from my old brush. My gums feel noticeably calmer after two weeks, and the cleaning is just as thorough as before.

My gums used to bleed every time I brushed, but after switching to these ultrathin bristles for a few weeks, the difference is night and day. The gentler cleaning actually leaves my mouth feeling just as fresh as my old brush, if not better.
