Brush Refresh

Did you know your toothbrush should retire every three months? A fresh brush cleans better.

At a Glance

Swap your brush every three months, or when bristles fan out. Tie the change to the season start and store upright.

Why Three Months

After three months of twice-daily brushing, soft bristles lose spring and bend, cleaning less.

Seasonal Tiny Habit

Pick a seasonal date, summer, monsoon, winter, spring, and swap the brush. A tiny sticker on the handle reminds you.

Visual Cue

You can spot a worn brush from above: new bristles form a rectangle, old ones spread wider.

Electric Brush Heads

Electric heads follow the same three-month rule. Some have colour-coded bristles that fade as a cue.

After Illness

For a cold you usually keep the brush; after a serious infection many replace it. Keep brushes separate while ill.

Storing Your Brush

Rinse, tap dry, and stand the brush upright to air-dry. Avoid closed cases daily.

What New Brush Won't Fix

A new brush helps, but technique matters more, two minutes, twice a day, fluoride, floss.

When to See Dentist

See a dentist if gums bleed long, a tooth is loose, swelling, night pain, or ulcer persists.
