Do Saint Bernards have dental problems?

Saint Bernards are prone to periodontal disease (common in all dogs) and lip fold dermatitis — an infection of the skin folds around their heavy, drooping lips. Their characteristic heavy drooling and deep lip folds create conditions where bacteria and yeast thrive, causing bad breath and skin infections. Large breeds are also at higher risk of fractured teeth from hard chews.

How do I clean a Saint Bernard's lip folds?

Clean Saint Bernard lip folds daily using a chlorhexidine wipe or soft cloth dampened with dilute chlorhexidine solution. Wipe out debris and moisture from inside each fold, then dry completely — residual moisture causes bacterial and yeast regrowth. Blot folds dry after every meal and water session. Keep fur inside folds trimmed short.

How often should a Saint Bernard have teeth cleaning?

Annual professional dental cleaning under general anesthesia is recommended for most Saint Bernards, beginning at 10–14 months of age. Dogs with dental disease or rapid tartar accumulation may need cleaning every 6 months. Giant breeds require careful anesthetic management, so choose a vet with giant-breed experience.

Can Saint Bernards eat bones?

No — hard bones, antlers, and hard nylon chews should be avoided in Saint Bernards. Their large jaw muscles generate substantial bite force, and large-breed dogs commonly fracture teeth on hard objects. Safe chew alternatives include thick bully sticks, VOHC-approved dental chews for giant breeds, and rubber chew toys like Kongs.

Saint Bernard Teeth: Dental Problems, Lip Fold Care & What To Know

Saint Bernards are iconic gentle giants — large, drooly, warm-natured dogs with a devoted following. Their enormous frame and famously heavy jowls create a specific set of dental and oral health challenges that owners need to understand early. Dental disease is nearly universal in dogs, but Saint Bernards face some particular vulnerabilities tied to their anatomy that make preventive care especially important in this breed.

Saint Bernard Dental Anatomy

Saint Bernards have large jaws and correspondingly large teeth. Unlike small breeds where the jaw is too narrow for the teeth, Saint Bernards have ample space — which means crowding is generally less of a problem. However, their size comes with its own considerations:

Large carnassial teeth: The upper 4th premolars and lower 1st molars are impressively large in Saint Bernards. These teeth are the primary shearing teeth and are also among the most commonly fractured in large breeds that chew aggressively
Pendulous lips and heavy jowls: The classic Saint Bernard “look” — heavy, pendulous lips and substantial skin folds around the mouth — creates ideal conditions for moisture, bacteria, and yeast accumulation
Significant drooling: Saint Bernards are among the heaviest-drooling breeds. Saliva constantly bathing the lip folds accelerates the bacterial overgrowth that causes lip fold dermatitis
Large mouth: The size of the mouth means there’s a lot of tooth surface to clean — brushing a Saint Bernard takes more time than brushing a small breed

Common Dental and Oral Problems in Saint Bernards

Periodontal Disease

As with all dogs, periodontal disease (plaque → tartar → gum inflammation → bone loss) is the most common dental problem. Saint Bernards aren’t more genetically prone to periodontal disease than average, but their large mouths and heavy drool mean there’s more surface area for plaque accumulation, and the saliva environment around their lips creates additional bacterial reservoirs. Over 80% of dogs show signs by age 3, and Saint Bernards are no exception.

Lip Fold Dermatitis

This is arguably the most distinctive oral health issue for Saint Bernards. The deep skin folds around the commissures (corners) of the mouth and beneath the lower lips trap saliva, food debris, and moisture, creating an ideal environment for bacterial and yeast infections. Signs include:

Musty, sour, or yeasty odor from around the mouth — distinctly different from dental-related breath
Brown or black discoloration of the skin inside the lip folds
Redness, moisture, or discharge inside the folds
Pawing at the face or rubbing the muzzle on surfaces

Daily cleaning and drying of the lip folds is essential maintenance for Saint Bernards. Many owners build it into the same routine as ear cleaning and nail trimming. For severe or chronic cases, surgical lip fold correction (cheiloplasty) can provide permanent relief.

Fractured Teeth

Large breeds are more likely to receive hard chew items, and large-breed jaws can generate considerable bite force. Saint Bernards can fracture teeth — particularly the upper carnassial teeth — from hard bones, antlers, or nylon chews. A fractured tooth that exposes the pulp causes significant pain and requires veterinary dental treatment (root canal or extraction).

Enamel Wear

Saint Bernards that play fetch obsessively (some individuals carry balls constantly) can develop enamel wear on the incisors from the repetitive friction of the ball. Ball-caused dental wear can progress to pulp exposure in severe cases. Use rubber or soft toys for fetching to reduce this risk.

How to Care for Saint Bernard Teeth

Daily Brushing

Daily brushing is the foundation of dental care for Saint Bernards, as it is for all breeds. Use a large-headed dog toothbrush suitable for giant breeds — or a finger brush for thorough access. The large jaw means brushing all surfaces takes longer than for small breeds. Pay particular attention to the outer surfaces of the carnassial teeth (upper premolars and molars) where tartar accumulates fastest.

Start brushing habits in puppyhood. Saint Bernard puppies are large and exuberant, but they’re responsive to patient habituation. A puppy that accepts brushing easily becomes a very manageable adult despite their size.

Lip Fold Care — Daily

After every meal and water session, blot the lip folds dry and wipe them out with a chlorhexidine wipe or dampened cloth. Dry the folds completely after cleaning. Keep the fur inside the folds trimmed short to reduce moisture retention. This must be a daily practice — not occasional — for Saint Bernards.

Appropriate Chew Selection

Given the fracture risk in large breeds, avoid:

Real bones (cow knuckle, marrow bones, recreational bones)
Antlers and horns
Hard nylon chews

Safe options include:

VOHC-approved dental chews in giant-breed sizes
Thick bully sticks
Large rubber chew toys (Kong-type)
Raw hides (under supervision, limited quantities)

Water Additives

VOHC-approved dental water additives are a useful supplementary tool for Saint Bernards — their large daily water intake means a water additive delivers more active ingredient than in smaller dogs. Choose a tasteless, odorless formula to avoid deterring drinking in a breed that needs to stay well-hydrated.

Professional Dental Cleaning for Saint Bernards

Annual professional dental cleaning under general anesthesia is the standard recommendation for Saint Bernards. The cleaning should include:

Full-mouth dental X-rays
Complete periodontal probing
Scaling and polishing of all tooth surfaces
Examination of lip folds

Anesthesia considerations for Saint Bernards: Giant breeds require careful anesthetic management. Make sure your vet is comfortable with giant-breed anesthesia protocols, uses pre-anesthetic bloodwork, has appropriate drug doses calculated for body weight, and monitors body temperature throughout (giant breeds can develop hypothermia during long procedures). Weight-based drug dosing is critical — underdosing a large dog is a real risk with less experienced practices.

Saint Bernard Dental Care Timeline

8–12 weeks: Daily mouth and lip fold handling; introduce enzymatic toothpaste taste
3–4 months: Begin gentle brushing; establish daily lip fold cleaning routine
5–6 months: Check for retained deciduous (baby) teeth; any retained teeth should be extracted promptly to prevent crowding and abnormal adult tooth positioning
10–14 months: First professional cleaning; establish the annual dental exam routine
Every year: Professional dental cleaning with full-mouth X-rays throughout life
Daily: Brushing + lip fold cleaning + appropriate chewing

Costs of Saint Bernard Dental Care

Professional cleaning: $400–$800 annually (giant breeds may cost more due to higher drug doses and longer procedure times)
Lip fold surgery if needed: $500–$1,500
Tooth fracture treatment: $800–$2,500 per tooth
Daily supplies: $20–$40/month

Saint Bernards are short-lived relative to their human emotional investment — their average lifespan is just 8–10 years. Good dental care isn’t just about avoiding dental pain; it contributes to systemic health and quality of life throughout their relatively brief time with you. Starting the lip fold cleaning and brushing routine in puppyhood, getting regular professional cleanings, and making smart chew choices are the three pillars of Saint Bernard oral health.
