Gentle vibrations/oscillations, not audible, not visible, and not perceptible.

If the teeth are free of tartar and gums and are not red/swollen, clean approximately once or twice a week. For tartar/swollen gums as often as possible without stress. There aren’t any harmful side-effects!

No. The ultrasound generated by CleanyTeeth for Dogs is not comparable to the „hard“ ultrasound used by dentists and veterinarians. Versions of the technology have been used on humans for over 20 years.

All cat lovers, we are working on this. At the moment, the brush heads are too big today. We will redesign the heads and keep everyone posted. May we suggest you sign up for our email newsletter, so we can reach out later to you. Concerning brush head for cats. Our engineers tell us we can trim the brush head i.e. cut/reduce the height of the bristles by 40 – 50%. Shortening the bristles will not lessen the ultrasound oscillations. You could exchange the brush heads that come with the CleanyTeeth system for the "cat-sized" heads.

The warranty is two years. It is possible to buy the third year of warranty.

One dog will likely consume 3 tubes per year. You should place around half an inch of toothpaste onto the brush head. Each tube is 2.54 fl. oz or 75ml. The life of an unopened tube is several months at least while unopened tubes can safely be used up to 2.5 – 3 years.

The factory is located in Germany (Black Forest) within 250 kilometers of Frankfurt.

Absolutely not. We don't use plastic, micro-plastic, micro-sized plastic within any of our toothpaste or cosmetic products. We don't use any abrasive ingredients either.

Yes, it will work with other brands of toothpaste. The results from each could vary.

With some/ most toothpaste the most active ingredient is the abrasive particles. Our toothpaste doesn't contain any abrasive particles. With a typical toothbrush whether a power sonic toothbrush or a manual brush results occur by scrubbing/rubbing the teeth and gums hence abrasive particles are necessary. On the other hand, with the CleanyTeeth for Dogs, ultrasound waves/oscillations are generated which blow away/destroy germs and bacteria as well as small food particles. Our toothpaste generates nano-bubbles which aid in the destruction of the germs and bacteria. Further, the ultrasound waves penetrate through some layers of gums to harm germs & bacteria. Similar forms of technology have been used on people for over 20 years. It has been proven safe and effective.

Each brush head can be used + - 30 times. The brush head needs to be changed when the bristles begin to fray and bend.

The estimated life of the product is + 5 years.

We recommend the single brush head for an 18 lb/ (8.2 kilo) dog.

For 2 dogs, you must decide how many "handles" to buy. We recommend brushing their teeth twice or perhaps once per week so you could keep changing the head. However, some people might prefer to buy two devices/handles.

Changing the brush heads is easy. There is a video showing how to do it in the section "TEETH CLEANING" / "How to clean your dog's teeth"
