Most dogs show signs of dental disease by age three. Here's how to keep your dog's teeth clean at home and avoid painful, costly problems.
Why dental care matters
By age three, most dogs show signs of dental disease. Left unchecked, plaque hardens into tartar, leading to gum infection, tooth loss, and bacteria that can affect the heart and kidneys. The good news: a few simple daily habits prevent most of it.

Brushing is the gold standard
Brushing your dog's teeth with a dog-specific toothpaste (never human toothpaste — it's toxic to dogs) is the single most effective thing you can do. Start slow, let them taste the paste, and build up to a gentle daily routine. Even a few times a week makes a real difference.
Dental chews do the heavy lifting
For days you can't brush, a daily dental chew like [Greenies](/products/greenies-original-dental-treats) helps scrape away plaque and freshen breath. Look for chews with the Veterinary Oral Health Council (VOHC) seal, which means they're proven to reduce plaque and tartar.
Other easy wins
Dental water additives, dental-formulated diets, and chew toys all add up. The goal is daily mechanical action against plaque before it hardens into tartar (which only a professional cleaning can remove).
Don't skip professional cleanings
Even with great home care, most dogs need occasional professional cleanings under anesthesia. Your vet can spot problems early — watch for bad breath, red gums, or reluctance to chew, and get them checked.
