| Tooth scaler is a veterinary dental instrument. Tooth scaler is used on the teeth of dogs or cats to effectively scrape off tartar, plaque, and bacteria-harboring calculus. It works on the surface of the teeth, below gum line, and between the teeth. There are two types of tooth scalers. A single-ended scaler that has a blunt edge to be used for scraping. A Double-ended Scaler that has 2 different angled ends to reach difficult areas. Tooth scalers are made from durable stainless steel. They clean food deposits between the dog???s teeth.
