Common questions about our products

Why are the bristles soft?

We created the bristles to be soft so that it is gentle on the gums and teeth for people who have sensitive teeth. Also, you do not need to brush hard because the bioelectric microcurrent waves will do the work more than the bristles do.

Does my toothbrush use UV Light?

We do not use UV light.

We use a LED blue light (450nm waves) which is not harmful.

What is the function of the blue light?

The Blue Light LED light of our Great Gums One and Great Gums
has two functions: 

Our blue light indicates that 10 million microcurrent waves per second are cleaning your teeth where no other toothbrush can reach. 

It has teeth-whitening benefits which can be enforced by adding special toothpaste.  

Does the toothbrush come with batteries?

Yes, all our toothbrushes come with a battery so you can start using it immediately. The Simple Pro Battery comes with 2 extra AAA batteries and the Simple Pro Rechargeable comes with a C-type cable to charge the Lithium-ion battery. 

Why Is there not a timer for the 2:30 brushing time?

The blue light indicates that the waves are activated. It shuts off automatically after 2:30 minutes.

Is the battery of the Simple toothbrush replaceable?

Our Simple toothbrush is an entry-level model and a great travel companion due to its smaller size and lighter weight. The battery is NOT replaceable. Our Simple Pro models come with extra brush heads and extra batteries if you choose a Simple Pro Battery. Our Rechargeable model comes with extra brush heads and a C-type cable.

Why does my electric toothbrush have no vibration?

Our toothbrush doesn’t vibrate, rotate, or wiggle since it is not motorized. Our patented GREAT GUMS core chip creates the AC/DC current that is converted into low voltage waves (0.7 V) in the brush head. This happens as imperceptibly as sending a radio signal.

My toothbrush is not working. What will you do about it?

We strive to deliver excellent product experience but once in a while there is a technical problem.

Don't worry - you're covered for one entire year.

Just let us know. We'll send you a new toothbrush and a free return label to send us back what's not working so we can continuously improve our product quality and service.

What type of battery is in the Great Gums Pro Rechargeable?

Our Pro Rechargeable is powered by a Lithium-ion battery. 


Some of our general common questions

Can I use any toothpaste?

For dental cleaning purposes, you may use any toothpaste you like for a fresh feeling.

For adding a whitening effect, you would need to use a special whitening gel or toothpaste. However, we do not sell any whitening gel or toothpaste currently.

What do you mean when you say no physical contact? Does that mean that I don’t touch my teeth with the toothbrush?

Yes, technically, you do not need to touch your teeth since 10 million bioelectric microcurrent waves per second will do the work imperceptibly and remove 6 times more plaque than regular brushes.

We just added bristles because old habits die hard. So, you can brush just as you like and use toothpaste for a fresh feeling.

Is my toothbrush actually effective? I need more research or scientific evidence for people to believe that my toothbrush is actually effective

The efficiency of our technology has been researched and proven in several clinical studies at the Yonsei University Dental School and Ulsan University Hospital and i.e. published on in the national library of medicine (USA)

You can check out our website at for a more in-depth explanation showing how our innovative technology is effective to our teeth and gums.

Why do I use toothpaste with it? I would think you wouldn’t need it and it seems it is blocking the effectiveness of the blue light.

Our waves are created with a very low voltage (0.7 V) and need water as a conductor to effectively impact the plaque structure. Toothpaste has two benefits - it creates a watery environment for our waves to work and it leaves a fresh and minty feeling.

Our blue light has a mild teeth whitening effect when used together with the chemicals typically present in special whitening agents. Without those agents, the blue light does not have any effect on teeth, gums, or dental plaque.
