OEM vs Compatible Replacement Heads

OEM is the manufacturer’s head; “compatible” often means a separate seller claim.

What matters for this question

OEM identifies the toothbrush maker’s own refill. A compatible third-party part is a separate product whose claimed fit must be checked for the exact handle.
Do not promote a seller claim to a manufacturer-supported result or assume smart recognition and warranty terms remain the same.

How to apply it

An OEM head can still have different pack sizes or regions, and a third-party claim can refer to only some handles in a family. Keep maker evidence and retailer wording separate. A search result containing “compatible” is a lead for inspection, not a verdict from BrushMatch.
