Atomy Dental Sonic replacement heads are a refill product. The Korean listing for product 002023 describes four replacement heads with protective caps. It does not describe four rechargeable toothbrush bodies.
Read the full product name before comparing prices. A refill pack and a complete powered toothbrush solve different purchasing needs.
Use the model marking, not the colour
Find the product or model name on the body you already own or in its manual. A white handle and a white replacement head are not enough to establish compatibility, and similar-looking connectors do not prove that parts fit.
Atomy’s separate Korean Dental Sonic body listing, product 002230, identifies model ATB-KR22. It lists a body and accessories including two heads. That helps distinguish the complete device from refill product 002023; it does not establish compatibility with every generation or another brand.
If your body has a different or unreadable marking, use this question with the official support team:
“I own a Dental Sonic body marked [model]. Is refill product 002023 suitable for this exact model? I need replacement heads, not a new body.”
Do not force or modify a part to make it fit.
Compare like-for-like orders
| Listing | Purchase being considered |
|---|---|
| Replacement-head product 002023 | Four heads and protective caps |
| Complete Dental Sonic product 002230 | A body with the accessories specified in that listing |
A protective cap is not a charger. Check the contents of the exact order rather than treating everything pictured in related-product sections as included.
If you need a device for another person, buying more heads is not the same as buying another powered body. Decide which item is actually missing before judging one price against the other.
When the refill arrives
Compare the product name and count with your order before using it. If the model or contents appear wrong, keep the packaging and ask about the mismatch.
Once the correct part is established, follow the device manual for fitting it. This guide concerns selecting the right purchase, not disassembling or repairing the motorised handle.
