When a dog has tooth decay, it is best to send the dog to the hospital and extract the tooth after anesthesia to avoid affecting the surrounding normal teeth. However, for elderly dogs, you should carefully consider whether to extract teeth because older dogs may not be able to tolerate anesthesia. The main purpose of owners’ daily cleaning and protection of their dogs’ teeth is to avoid the formation of tartar. They can remove the food remaining between the dog’s teeth after feeding, or they can also use a piece of cloth soaked in saline to scrub the teeth.
