How do I brush my dog's teeth?

The 30-day ramp (skip this and most dogs quit)

1. Days 1-7: Let the dog lick a pea-sized amount of enzymatic dog toothpaste off your finger. Pair with a treat. Goal: paste = good.
2. Days 8-14: Rub the paste on the outside of the canine teeth with a finger. 10 seconds. Treat. Goal: mouth handling = good.
3. Days 15-21: Introduce the brush without paste. Touch the outside of a few teeth. Treat. Goal: bristles feel = neutral.
4. Days 22-30: Full brush with paste, outside surfaces only, 60 seconds total. Treat. Goal: 60-second daily habit.

Technique and tools that actually work

Angle the bristles 45° toward the gum line and use small circular motions, this is the same technique that works in human dentistry and is the only technique shown to disrupt subgingival plaque. Focus on the outside surfaces of the upper canines, upper premolars, and upper molars, that is where most plaque and tartar accumulates.

Never use human toothpaste, fluoride is toxic in dogs, and any product that lists xylitol is deadly at doses far below what a dog will swallow from a swallowed brushful. VOHC (Veterinary Oral Health Council) seal on toothpaste, water additives, and dental chews signals independent efficacy testing.

What to do if brushing is not enough

Daily brushing slows periodontal disease but does not reverse existing tartar. Once tartar is visible, a professional dental cleaning under general anesthesia is the only way to remove it, avoid 'anesthesia-free' cleanings, they cannot clean below the gum line where periodontal disease actually lives and cannot take the dental radiographs needed to catch resorption, root abscesses, and bone loss.
