This is your reminder to replace your toothbrush every 3 months to
avoid brushing with disgusting bacterial buildup.
Most people use their brush until it looks like a scrub brush
for tires.
Once those bristles splay outward, they stop removing plaque along your gumline
and start trapping moisture and bacteria between the fibers every single morning.
The rule is simple.
Replace it every ninety days, or immediately after you get over a
cold or flu so you do not reinfect yourself.
An easy hack is setting a recurring calendar alert on the first
day of every season.
A fresh five-dollar brush today saves you a ton of painful dental
work down the road.
Go check your bathroom cabinet right now.
