Brush Head Replacement Date Calculator

Estimate a reminder date from first use and your chosen interval. Replace sooner if bristles are worn.

Use the tool

How this result is calculated

The reminder adds calendar months to the start date, clamping to the last day of a shorter month. If a selected head has a manufacturer interval in this catalog, it fills the interval field; otherwise enter your own based on the manual. The ADA’s general advice is every three to four months or sooner if bristles are frayed.

Before acting

Check the current manufacturer package and full model code. BrushMatch has not physically tested fit, and calculator estimates are not shopping quotes.
