Philips sonicare 5100 replacement heads g2
Sonicare 5100 replacement heads must match the handle connection and the G2 gum-care head system specified for that model.
The short answer
The Sonicare 5100 uses a removable head that transfers the handle’s powered motion to the bristles. Compatibility depends on the handle and head system, so a head labelled for a different connection may not fit or function as intended.

What is the direct answer?
What does this question mean?
Check the exact model marking, packaging, and manufacturer compatibility information before buying. A gum-care head may have softer or differently shaped bristles than a standard plaque-control head, but the handle still supplies the cleaning motion.
What can you do next?
Rinse the head after brushing, let it air-dry, and do not share it. Bend or splayed bristles, a loose fit, or a damaged head are signs to stop using it and fit a compatible replacement.
When should you seek dental care?
A powered brush cannot treat untreated gum disease, decay, or a loose tooth. A dental examination can distinguish technique-related irritation from inflammation that needs professional cleaning or treatment.
What should you ask the dentist?
Ask the retailer or manufacturer to confirm the complete handle model and the exact head connection, rather than relying only on the word G2.
