Why isn’t my electric brush working?

Your battery might need charging. Remember to recharge the brush regularly.

My toothbrush is making too much noise. How do I fix this?

This could be an issue with the brush head. Remove the brush head reattach to make sure it’s fitted properly.

Is a tingling feeling during use normal?

If you’re using an electric toothbrush for the first time, you may not be used to the feeling of it yet. The vibrations that help the cleaning could be making you feel this way. Give it a little time and the tingling will feel like nothing at all!

The toothbrush battery won’t charge. What do I do?

There’s probably no current flowing through. Test the socket you’re using as well as the plugs to make sure everything is secured properly.

This is an in-built feature that reminds you to switch quadrants when you brush at 30 second intervals.

A fully charged ION-Sei brush should last you between 2 and 3 weeks if you use it twice a day.

When should I replace my brush head?

Follow the same guidelines for replacing brushes when replacing ION-Sei brush heads. 3 months is our recommendation!

How do I take out the battery?

It’s hard to remove and reattach brush heads on the toothbrush. How do I fix this?

A brand-new ION-Sei Toothbrush can be a little tough to deal with. Bear with it for a small while, because repeated use will make the brush head easier to attach.

The head is loose and keeps falling off when I use it. What’s the problem here?

This is an indication that the barb inside the brush head has broken. Please have the brush and its head checked by a specialist dealer or contact us. Remember that when you attach and remove the brush head, you should never try to twist the brush head. Simply remove it by pulling upwards and attach by pushing it down. Twisting the brush head can damage the brush head and damage both items.


Is it okay to use the ION-Sei toothbrush with dental implants?

Hormonal imbalances in the body during pregnancy can cause sensitivity to the micro current. Please consult with your doctor and dentist before you use it.

Most people with braces are able to use this brush with no issues. However, check with your dentist to make sure they approve it.

Isn’t UV light harmful to us?

The UV-LED is in very low quantities, so it’s not harmful.

Can the titandioxide bar be depleted with constant use?

The amount of ions used during every brushing session is so tiny that the bar will not get depleted.

Dried toothpaste has gotten stuck in the gaps of my brush. How do I clean it?

Dried toothpaste comes off easily when wiped with a damp towel. We recommend you clean it with a wet washcloth regularly.

Does using toothpaste with this brush affect the cleaning properties of the technology?

Using ION-Sei with just water is recommended but using toothpaste does not impact the ionic technology at all.

Does the UV light have an antibacterial or bleaching effect?

The UV-LED technology itself is not antibacterial, nor does it bleach the teeth.
