Dog Plate for Teeth Plaque: This ultra tooth cleaner for domestic animals uses high-frequency vibration technology to effectively remove plaque and debris from the teeth of dogs and other pets. It helps prevent periodontal disease and other dental issues. Note: When first using the tooth cleaner, select the soft mode until your dog becomes accustomed to the sensation. Efficient cleaning action removes tartar, food particles, and residue from hard-to-reach spaces. The device features an IPX7 waterproof rating, ensuring durability and safe cleaning. To verify functionality, tap the tip of the device on a hard surface such as stainless steel or glass. A slight noise will confirm proper operation. Note that no noise should be heard during actual teeth cleaning. Do not test the device on plastic, wood, or soft materials, as it will not produce sound on these surfaces.
