Dental disease is among the most common health conditions in dogs generally, and French Bulldogs are disproportionately affected because of the structural problem their brachycephalic jaw creates. The breed’s teeth are crowded into a jaw that was shortened by selective breeding, producing an arrangement where normal chewing does not clean the teeth the way it does in a dog with normal jaw proportions.
This is not a problem that can be solved by choosing the right food. It requires active management from puppyhood, starting with a brushing routine established before the dog has formed strong opinions about having its mouth touched.
The dental anatomy problem
A standard canine jaw holds 42 permanent adult teeth. The French Bulldog has the same number of teeth in a jaw that has been compressed to a fraction of the length it would have in a normally conformed dog.
The results are:
- Rotated teeth sitting at angles rather than in a normal arch
- Overlapping teeth where two teeth share a space designed for one
- Teeth retained at abnormal heights because there is no space for normal eruption
- Teeth that face inward toward the tongue or outward toward the cheek
These malpositioned teeth accumulate plaque in the gaps and overlaps far more rapidly than normally spaced teeth. The normal mechanical cleaning action of chewing, the back teeth grinding against food, does not effectively clean the inner surfaces of overlapping teeth. The result is rapid plaque accumulation, calculus formation and accelerated periodontal disease.
Puppy teeth and the transition to adult teeth
French Bulldog puppies have 28 milk teeth that begin to come through from around three weeks. These start to be replaced by adult teeth from around three to four months of age, with the transition typically complete by six to seven months.
The teething period can be uncomfortable and most puppies chew more intensively during it. This is normal and appropriate; provide appropriate chew toys (soft enough not to fracture the milk teeth, firm enough to provide relief).
A common problem during the transition is retained milk teeth: puppy teeth that do not fall out when the adult tooth erupts. This is more common in brachycephalic breeds where the compressed jaw leaves no room for the adult tooth to displace the milk tooth normally. If a puppy tooth is still present at six months alongside the adult tooth in the same position, have your vet assess it. Retained milk teeth are usually extracted, as they contribute to crowding and provide an additional plaque-trapping surface.
Establishing a brushing routine
The single most impactful thing an owner can do for their French Bulldog’s dental health is establish daily brushing. This is straightforward with puppies and more challenging with adult dogs who have not been conditioned to it. Start in the puppy period.
Equipment: A dog-specific enzymatic toothbrush (or a finger brush, which many owners find easier to manage in a brachycephalic mouth) and dog-specific enzymatic toothpaste. Never use human toothpaste.
The introduction process:
-
Start by touching the lips and mouth area while the dog eats or receives treats. No toothbrush yet. The goal is a dog that does not object to the mouth being touched.
-
Let the dog taste and sniff the toothpaste from your finger. Most dogs accept food-flavoured toothpaste readily.
-
Rub the toothpaste on the teeth with your finger. Reward. Still no brush.
-
Introduce the brush with toothpaste but only against the outer surface of the front teeth initially. Reward. Progress over sessions.
-
Gradually extend to the back teeth and inner surfaces over multiple sessions.
The whole process can take two to four weeks if the dog is cooperative. For a dog that was not habituated in puppyhood, it may take longer and require more patience at each stage. The goal is a dog that accepts the whole mouth being brushed as a matter of routine.
Technique: Small circular or back-and-forth motions along the gum line. The gum line is where plaque accumulates and where periodontal disease begins; concentrate effort there rather than on the visible tooth surface. Brush the outer surfaces first, these are easier to reach and accumulate the most plaque. Inner surfaces are harder to access in a brachycephalic mouth but should be reached where possible.
Signs of dental disease
Calculus. Yellowish-brown deposits on the teeth, most visible near the gum line on the back teeth. This is mineralised (hardened) plaque that cannot be removed with a toothbrush. Its presence indicates that professional cleaning under anaesthesia is needed.
Gum redness or swelling (gingivitis). Gums should be pale pink and firm. Red, swollen or bleeding gums indicate inflammation that is the first stage of periodontal disease.
Bad breath. Persistent bad breath beyond normal dog-breath intensity is typically caused by bacterial activity in the mouth associated with dental disease. It does not resolve with brushing alone when calculus and periodontal disease are present.
Pain signs. Reluctance to eat hard food, chewing on one side, pawing at the face or mouth, sudden food refusal.
Loose teeth. In advanced periodontal disease, teeth become loose as the supporting bone is lost. This is a late-stage sign; the disease has usually been present for some time before teeth become mobile.
Professional dental cleaning
Professional dental cleaning under general anaesthesia allows:
- Removal of all calculus, including subgingival deposits below the gum line that no toothbrush can reach
- Full examination of every tooth and the gum pockets around each tooth
- Dental radiography to assess the bone and root health below the gum line
- Extraction of teeth that are non-salvageable
For French Bulldogs without a home brushing routine, annual professional cleaning is often needed. Dogs with a good home brushing routine typically require professional cleaning every two to three years rather than annually.
The anaesthetic risk for brachycephalic breeds is higher than for standard-conformation dogs, which is one of the stronger arguments for prevention through regular brushing. A dog that needs one professional clean every three years due to good home care has significantly lower anaesthetic exposure than a dog needing annual cleans.
The full range of grooming tasks that form the French Bulldog maintenance routine is in the grooming guide. The other regular care tasks requiring similar fold-care diligence are covered in the skin fold cleaning guide. For the cost of professional dental procedures and how insurance typically handles dental treatment, the vet costs guide covers the figures.

Frequently asked questions
-
French Bulldogs have a full complement of 42 adult teeth in a jaw that has been compressed by selective breeding. The result is dental crowding: teeth that overlap, rotate and are positioned incorrectly because there is not enough jaw space for them. Crowded teeth accumulate plaque and tartar faster than normally spaced teeth because the normal self-cleaning action of chewing does not reach the spaces between overlapping teeth. This makes the breed significantly more prone to periodontal disease than most other small breeds.
-
Daily brushing is the goal. Even three to four times per week produces significantly better dental health outcomes than brushing once a week or not at all. The accumulation of plaque into calculus (tartar) begins within 24 to 48 hours; daily disruption prevents this accumulation from hardening onto the tooth surface. Weekly brushing removes some soft plaque but does not prevent calculus formation at the gum line where periodontal disease begins.
-
Dog-specific enzymatic toothpaste. Never use human toothpaste: it contains fluoride, which is toxic if swallowed, and often contains xylitol, which is acutely toxic to dogs. Enzymatic dog toothpaste is specifically formulated to work with the chewing action and contains enzymes that break down bacterial plaque. Flavours including chicken, beef and vanilla are available, most dogs tolerate the food-flavoured versions better than mint. The toothpaste is effective even without a perfect brushing technique; getting it on the teeth and allowing the dog to move it around with its tongue contributes to plaque control.
-
When there is calculus that cannot be removed with a toothbrush (the hard, yellowish-brown deposits on teeth, particularly near the gum line), visible gum redness or bleeding on contact, bad breath that does not improve with brushing, pain behaviours (reluctance to eat hard food, pawing at the mouth), or loose teeth. Professional dental cleaning under general anaesthesia allows full examination of every tooth, removal of subgingival calculus (below the gum line) and treatment of diseased teeth. This typically needs to be done every one to two years in French Bulldogs without a home brushing routine.
-
Veterinary-approved dental chews (VOHC-accredited products) have evidence of reducing plaque and calculus when used daily. They are not a replacement for brushing but provide a meaningful supplement. For French Bulldogs, choose size-appropriate chews that require genuine chewing action rather than soft treats that are swallowed quickly. Avoid very hard chews (raw bones, antlers, very hard nylon toys) that can fracture the teeth, a cracked tooth often requires extraction. The Veterinary Oral Health Council (VOHC) seal identifies products with efficacy evidence.
