Keeps your teeth feeling clean,
Verified Purchase(What is this?)
This review is from: Braun Oral-B EB20-4 Precision Clean Replacement Rechargeable Toothbrush Heads (Pack of 4) (Packaging May Vary) (Personal Care)
I have had an Ora B electric toothbrush for many years and use these daily along with the Tri Zone heads. Both the heads make your teeth feel as though thy have had a proper clean, thus making your mouth feel fresh.
