Does an Indoor Dog Still Need Brushing?

1 Why Brush

Brushing a dog’s teeth is essential—dogs can’t floss, so food bits lodge between teeth and breed bacteria if not cleared, hurting long-term health.

Skip oral care and plaque and tartar build up just like in people, leading to bad breath, gum disease, tooth pain, and even infection spreading to other organs.

2 When to Start

Dogs have 28 baby teeth and 42 permanent teeth, and need at least one professional dental cleaning per year.

Start brushing around six months, once all baby teeth are in—puppies under six months aren’t ready.

Build the habit young, especially with large breeds, so by the time it’s a big dog it won’t shove you aside when you reach for its mouth.

3 How to Brush Safely

Pick the right brush: not a human one—use a soft child’s brush or a pet brush. Finger brushes or rubber finger caps are best.

Pick the right paste: human toothpaste is toxic to dogs because of its fluoride. Use pet paste in flavors like mint, peanut, or chicken to make brushing easy.

Brush teeth and gums gently, from base to tip, and don’t forget the outer (cheek) side where plaque forms.

Praise the dog afterward so it associates brushing with love. Never force the mouth open—you risk a bite. If there’s oral disease, see a vet; brushing prevents but doesn’t treat.
