We're perfectly confident in our product. However, if you're unsatisfied with your Great Gums toothbrush, we offer a 30-day return policy (from the date of delivery).

We will issue a full refund to the original payment method. Please note that we cannot refund shipping charges.

Our 30-day return policy covers the initial Great Gums Clinical Grade brush kit.
Unfortunately, we do not accept returns of replacement head packages for sanitary reasons.

USPS has no restrictions on very small Lithium-ion batteries like the ones we use, provided they are

a) installed correctly in the equipment or
b) packed with equipment but not installed in the equipment.

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.

We do not use UV light.

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

The Blue Light LED light of our Great Gums One and Great Gums
Pro 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.  

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. 

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

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.

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.

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.

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

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.

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.

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) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8394510/

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

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.
