Question 1

Will these replacement heads fit my Oral-B iO 9 or iO 10 model?**

Accepted Answer

These heads are designed to work with all iO models, including the 9 and 10. However, several users on Reddit and in reviews have noted a slightly looser fit on the iO 7 and above – nothing that affects brushing, but the connection may feel less snug than original Oral-B heads. If you use an iO 7+, we recommend trying a single head first before buying the full pack.

Question 2

Are the bristles soft or hard? I have sensitive gums.**

Accepted Answer

The bristles are medium-firm – similar to standard Oral-B heads but not as gentle as the “sensitive” variant. Some TikTok reviewers with sensitive gums found them a bit scratchy at first, though others adapted after a few uses. If you usually buy the softest bristle options, consider sticking with original Oral-B or looking for labeled “ultra-soft” alternatives.

Question 3

Do the protective covers actually stay on during travel?**

Accepted Answer

The covers are functional for storage but not super secure – several buyers mention they pop off easily if bumped in a bag or dropped upright. They work fine for daily bathroom drawer use, but for travel, you might want to secure them with a rubber band or use a dedicated toothbrush case.

Question 4

How long do these heads last compared to genuine Oral-B ones?**

Accepted Answer

Many users report that the cleaning performance starts to fade around the 3–4 week mark, even though the indicator bristles suggest 3 months. Genuine Oral-B heads typically maintain effectiveness for longer. If you’re a heavy brusher or want maximum plaque removal, you’ll likely replace these more often – still a good value for the price, just plan for shorter cycles.

Question 5

What if the heads don’t fit my toothbrush – can I return them?**

Accepted Answer

Yes, the seller offers returns and refunds for fit issues, though you’ll want to check the specific return policy at checkout, as some sellers require items to be unopened. Most buyers who reported fit problems did receive refunds, but we recommend testing one head immediately upon arrival to ensure compatibility.
