I purchased this, but my dog didn't like it, so I'm listing it immediately after it arrived today. I only tried it once, so it's a used item. I briefly touched the tip to my dog's teeth, and then disinfected it with an alcohol wipe. This is a dental scaler for dogs, with 5 intensity settings. - Product Name: Dental Calculus Remover - Purpose: Dog teeth cleaning - Features: 5 intensity settings - Accessories: Charging cable, scaler, mirror - Design: White handle
