How we researched this guide: This article is based on a 2024 Royal Veterinary College VetCompass study of Shih Tzus, the 2019 AAHA Dental Care Guidelines, VCA Animal Hospitals, the American Veterinary Dental College (AVDC), and the Veterinary Oral Health Council (VOHC). Last reviewed: September 2026.
Dental disease is the most common health problem in Shih Tzus. A 2024 Royal Veterinary College study found periodontal (gum) disease in 9.5 percent of Shih Tzus in a single year, more than any other specific problem. The authors called oral hygiene a healthcare priority for the breed.
The good news is that dental disease is largely preventable. A few minutes of daily care can protect your dog from pain, tooth loss, and infection.
Why Dental Care Matters
AAHA notes that by three years of age, most dogs have some level of periodontal disease. Untreated, it causes mouth pain, infection, and other health problems. Many owners report that their dog seems like a new pet, happier and more active, after dental problems are treated.
Signs of Dental Problems
- Bad breath
- Yellow or brown tartar on the teeth
- Red, swollen, or bleeding gums
- Loose or missing teeth
- Chewing on one side or dropping food
- Pawing at the mouth or not wanting the face touched
- Swelling under the eye
How to Brush Your Shih Tzu’s Teeth
Daily brushing is the best way to remove plaque. VCA notes that brushing three times a week is the minimum to help prevent tartar.
Never use human toothpaste. VCA warns that human toothpastes contain ingredients that should not be swallowed and may contain xylitol, which is toxic to dogs. Always use a toothpaste made for dogs.
- Start slowly. VCA suggests rubbing your finger or a soft cloth along the outer surfaces of the teeth first.
- Introduce the toothpaste. Let your dog lick a little pet toothpaste as a treat.
- Add the brush. Use a small, soft brush or a finger brush.
- Focus on the outside surfaces. VCA notes that most periodontal damage happens on the outer surfaces, especially the large cheek teeth and the canine teeth.
- Keep it short and positive. About 30 seconds per side is enough. Praise your dog throughout.
- Replace the brush about every three months.
Dental Products We Recommend
Petsmile Professional Pet Toothpaste
Best for: daily brushing. Petsmile Professional toothpaste carries the VOHC seal for plaque. It is made for pets, so it is safe to swallow.
A Soft-Bristle Pet Toothbrush
Best for: reaching small teeth. A small, soft brush fits a Shih Tzu’s mouth more easily than a large one.
Greenies Teenie Dental Treats
Best for: extra help between brushings. Canine Greenies are on the VOHC accepted list for both plaque and tartar, and the Teenie size is made for dogs 5 to 15 pounds. Count them toward your dog’s daily treat allowance. See our treat guide for more options.

Look for the VOHC seal on any dental product. It shows the product met the council’s standards for reducing plaque or tartar.
Professional Dental Cleanings
Even with good home care, most dogs need professional cleanings. AAHA explains that a proper dental cleaning requires general anesthesia. This lets the vet clean below the gumline, take dental X-rays, and treat problems safely.
The AVDC does not recommend anesthesia-free cleanings. It explains that they cannot clean beneath the gumline, where the bacteria that cause periodontal disease live, and that white teeth do not mean a healthy mouth. Ask your vet how often your Shih Tzu needs a cleaning.
Watch for Retained Baby Teeth
Small breeds sometimes keep baby teeth after the adult teeth come in. Retained baby teeth crowd the mouth and trap food. Ask your vet to check at your puppy’s visits, often during spay or neuter surgery. Our puppy care guide covers early vet visits.
Frequently Asked Questions
How often should I brush my Shih Tzu’s teeth?
Daily brushing is best. VCA notes that three times a week is the minimum needed to help remove plaque and prevent tartar.
Can I use human toothpaste on my Shih Tzu?
No. VCA warns that human toothpaste contains ingredients that should not be swallowed and may contain xylitol, which is toxic to dogs. Use a pet toothpaste.
Are Shih Tzus prone to dental problems?
Yes. A 2024 Royal Veterinary College study found periodontal disease was the most common specific health problem in Shih Tzus, affecting 9.5 percent in a single year.
Are dental chews enough to keep teeth clean?
Dental chews with the VOHC seal help reduce plaque or tartar, but they do not replace brushing and professional cleanings.
Are anesthesia-free dental cleanings safe?
The American Veterinary Dental College does not recommend them. They cannot clean beneath the gumline, where periodontal disease starts, and may cause stress and discomfort.
