"Large ice cubes can also fracture teeth and should be avoided," says Dr. Alexander M. Reiter, head of the Dentistry and Oral Surgery Service at the University of Pennsylvania School of Veterinary Medicine. "Tennis balls are a popular toy for many dogs; however, they are very abrasive to teeth because they collect tiny particles of dirt and sand and will wear down the teeth and occasionally cause pulp exposure."
Reiter also recommends scheduling a professional examination to ensure optimum oral health in man's best friend.
"Your pet should have an annual oral examination performed by a professional to document the presence of abnormal conditions such as periodontal disease, fractured or decayed teeth, tumors, ulcers, etc.," he says. "Ultimately, there is no replacement for daily toothbrushing and periodic professional treatment at your vet."
