TENS for dental injection

Wisdom tooth extraction can be a very painful procedure and many patients fear the anaesthetic injection. This project focuses on reducing, or eliminating, the negative experience of the injection. Responding to this problem, I have designed a handheld dental TENS device to be used during the injection procedure. The product provides electric stimulation through the electrodes to reduce the pain signal from that area, while also distracting and relaxing the patient, reducing their stress. Considering the clinical environment and the dentist’s/patient’s behaviour, I have designed the product to be as simple and intuitive as possible to use to give patients a positive and pain-free experience, and designing the product form and application of materials to be fit for purpose.
