GUM
Our brand review.
Interdental brushes and flossing tools from SUNSTAR.
By Hello My Teeth editorial research · No hands-on testing
Our take.
Useful to compare if a powered water flosser is not the format you want. Prioritize an interdental tool you can size and handle appropriately; the right physical fit is a more useful starting point than a brand-wide ranking.
The product range
SUNSTAR GUM offers interdental brushes and floss products. The professional catalog describes different brush sizes and designs; regional product ranges may differ.
This assessment concerns the brand’s range and purchasing decisions. It does not award a best-product ranking or establish clinical performance.
Make size and access the first comparison
SUNSTAR GUM’s professional site includes an interdental size indicator and a regional product catalog. The source used here is international, so a size system or item shown there should be checked against the locally sold product.

| Your situation | First comparison | Why it matters |
|---|---|---|
| Buying an interdental brush | Get guidance on suitable size and technique. | Do not infer cross-brand equivalence from matching handle colors. |
| Reaching back teeth is difficult | Compare the handle and access you need. | Discuss whether another shape or format would be easier to use. |
| Shopping while travelling | Record the exact product and size details. | A familiar brand name does not guarantee the same regional range. |
A realistic buying scenario
If a hygienist demonstrates a particular brush, save the package or exact size information before shopping. A larger value pack is only useful if it contains the appropriate size. If you are trying to reach a difficult area, describe that access problem rather than automatically choosing the smallest or largest brush. The right comparison begins with how the tool fits the task.
Practical pros & cons.
Reasons to consider
- Several non-powered interdental formats are represented.
- Size-based brush options support a more specific discussion with a dental professional.
Limitations to weigh
- You may need advice to choose an appropriate brush size.
- A model shown in an international catalog may not be sold in your region.
Check before buying.
- Confirm local availability of the exact product and refills.
- Ask for sizing guidance instead of choosing by color alone.
- Compare handle reach, grip and replacement requirements.
Verify the exact product and regional instructions before making a decision. Prices, offers and availability are not tracked on this page.
What else to compare.
These options offer other ranges or formats to investigate; inclusion does not mean they are equivalent substitutes.
Frequently asked questions.
Can I choose a GUM brush by its color alone?
Use the exact size information and local product guidance. Colors should not be treated as universal sizing across brands or ranges.
Are all products shown in the international catalog sold in the US?
This review does not confirm that. Verify the local product and refill availability before planning a routine around an international listing.
Is GUM a direct replacement for Waterpik?
They represent different tools and routines. The comparison is useful for exploring formats, not for declaring that one device or brush is an equivalent substitute for everyone.
