Main Project – TENS For Dental Injection
The dental injection is necessary for wisdom teeth removal and other dental surgeries. The Intense pain feeling inside the mouth is one of some people’s most painful dental memories.
This device can reduce the pain signal passing to your brain by TENS ( transcutaneous electrical nerve stimulation).
As a product for a specific procedure, we simplify the operation. The device has a proper size for a handhold and a cloth cover for health and safety. The dentist and assistant place the pad, adjust the strength and give it to the patient. We try to reduce the pain and provide them with a sense of control through the product and the interaction with the dentist.
