## Product: Oral-B iO Series 9 Toothbrush
**Brand:** Oral-B

The brush heads for the **Oral-B iO Series 9 Electric Toothbrush** last about three months with regular use. 

The manufacturer recommends swapping them out every three months to keep up cleanliness and performance. 

The brush heads even come with indicator bristles that fade over time, reminding you when it’s time for a new one. 

According to our research, folks seem to agree with this timeline and often notice a drop in bristle effectiveness around the three-month mark, which matches what the manufacturer suggests.
