Question 1

Will these Dentia brush heads fit my specific Oral-B Braun model?**

Accepted Answer

They are designed for most Oral-B Braun electric toothbrushes except the iO Series. Many users confirm a snug fit on models like the Pro 1000, Vitality, Smart, and Genius. However, a small number of people report a slightly looser fit on older handles (model 5000 and before). If your toothbrush is over 5 years old, you may feel a wiggle—but most shoppers find them perfectly stable.

Question 2

Are these heads as firm and effective as genuine Oral-B refills?**

Accepted Answer

They are slightly softer than official Oral-B Precision Clean heads, according to many buyers who switched. While this still cleans well for daily use, some felt the gentler bristles required a longer brushing time. They’re a great budget-friendly option, but if you need rock-hard bristles, you may want to stick with OEM or try a firmer third-party brand.

Question 3

The blue indicator bristles faded fast— does that mean the head is already worn out?**

Accepted Answer

Dentia says the blue fades to remind you to replace the head every 3 months. However, many users noticed they fade more quickly than Oral-B’s official heads (sometimes within 3-4 weeks). This is a conservative indicator, not a sign the head is worn out. You can safely continue using the head until the bristles actually fray or splay—just check them visually.

Question 4

What’s the return / refund policy if I don’t like the fit or feel?**

Accepted Answer

Dentia generally offers a 30-day satisfaction guarantee through Amazon, and multiple users have received refunds after contacting the seller. Make sure to keep the packaging and contact customer support directly with your order number. Some shoppers felt the process was easy; a few had to push for a response. Always check the current listing for guarantee details.

Question 5

I saw TikTok videos complaining these heads loosen over time — is that common?**

Accepted Answer

A handful of TikTok and YouTube users did mention that the connection can feel looser after a few weeks of use, especially on older brush handles. The fix? Remove the head, rinse it, and press it back on firmly. If it still wiggles, a tiny dab of petroleum jelly inside the base can help. For most buyers, this wasn’t an issue, but it’s worth noting if you have a very old toothbrush model.
