Question:
What does the number on the toothbrush indicate?
When you buy a toothbrush, it saids medium or soft and then there is a number. I think it indicates the size of the brush but does a low number mean its small and a high number big??
Answers:
I believe it indicates how many bristles are in the brush. The Oral B 30 has fewer rows of bristles than the 35. It has been a long time since I've used them, but if memory serves correct that is what it means.
Oh! I forgot to mention.....please only use soft brushes. Just brush longer (2+ minutes), and change them every 2-3 months.
