Dental Disease in Maltese Dogs: Prevention, Cleaning & Care

Maltese are a charming toy breed with striking white coats—but their small muzzles and crowded teeth make them one of the dog breeds most prone to periodontal disease. For a Maltese entering senior life (around 8–9 years; expected lifespan 12–15 years), [dental disease](https://seniorpet.org/knowledge/siamese-cat-dental-disease "Dental Disease in Senior Pets") is not a cosmetic issue: it is one of the most common chronic problems that affects comfort, nutrition, and systemic health. This article summarizes what dental disease looks like in senior Maltese, how periodontal disease interacts with breed-specific conditions (mitral valve disease, collapsed trachea, portosystemic shunt, luxating patella, cataracts, white shaker syndrome), and practical, veterinarian-approved strategies for prevention, diagnosis, and treatment.

Why Maltese are at high risk

• Small-jaw conformation: Maltese have toy-sized skulls that often lead to dental crowding, rotation, and retained deciduous (puppy) teeth. Crowding creates tight interdental spaces where plaque and calculus rapidly accumulate.
• Early-onset periodontal disease: Small breeds develop gingivitis and periodontitis earlier than many larger breeds; plaque mineralizes quickly and subgingival (below-gumline) disease progresses silently.
• Frequent tooth fractures and retained teeth: Small crowns and narrow roots can predispose to fractures during chewing or when hard chews are used.
• Breed-prone systemic issues: Conditions common in Maltese—particularly [mitral valve disease](https://seniorpet.org/knowledge/cavalier-king-charles-spaniel-mitral-valve-disease "Mitral Valve Disease Guide") (MVD) and portosystemic liver shunt—raise the stakes for dental disease because bacteremia from oral infections can affect the heart or be handled poorly by a compromised liver.

What this means for an 8–9 year old Maltese: periodontal disease is likely present at some degree, and proactive management can prevent pain, tooth loss, and systemic complications.

How dental disease progresses in Maltese

• Plaque formation — within hours after brushing.
• Calculus (tartar) formation — days to weeks; visible as yellow-brown deposits.
• Gingivitis — reversible inflammation of the gum margin.
• Periodontitis — loss of attachment (pockets), bone loss around teeth, loosening and eventual tooth loss.
• Endodontic disease — pulp exposure, root abscess, draining tracts.
• Systemic spread — intermittent bacteremia can seed organs (valvular lesions, liver).

A key point: in small breeds like Maltese, the most damaging disease often lies beneath the gumline (subgingival). Visual home checks miss this, so periodic professional evaluation is essential.

Recognizing dental problems in your senior Maltese

Common signs (some subtle) in Maltese:

• Halitosis (bad breath) — the most common owner-observed sign.
• Tartar buildup on canines and premolars (visible as yellow/brown calculus).
• Red, swollen gums or gum recession around incisors and premolars.
• Drooling, pawing at the mouth, reduced interest in chews or toys.
• Difficulty eating or preference for soft food.
• Loose teeth, visible root exposure, or facial swelling (abscess).
• Behavioral changes: irritability, reluctance to be touched around the head.
• Coughing or worsening cough if dental disease contributes to aspiration — relevant for dogs with collapsed trachea.

If you note any of these signs, consult your veterinarian—especially for senior Maltese with known MVD, liver shunts, or on immunosuppressive therapy for white shaker syndrome, because infections carry higher risk.

Assessment and diagnostic testing

Before dental treatment, your veterinarian will typically recommend:

• Full oral exam under sedation/anesthesia to assess subgingival disease and pockets.
• Dental radiographs (intraoral x-rays) — indispensable for detecting root problems and bone loss.
• Minimum database: CBC, serum biochemistry, urinalysis — particularly important in seniors and if a portosystemic shunt or liver disease is suspected.
• Cardiac evaluation (auscultation, sometimes echocardiography) for dogs with heart murmurs or known/possible MVD—mitral valve disease affects anesthesia risk and may influence perioperative plans.
• Thoracic radiographs or tracheal evaluation if collapsed trachea is suspected (coughing, harsh coughing), because airway disease affects anesthesia and recovery planning.

References and standards: American Veterinary Dental College (AVDC) and Veterinary Oral Health Council (VOHC) emphasize the need for radiographs and anesthesia for full periodontal evaluation.

Professional dental cleaning: what to expect and why anesthesia is required

A true professional dental cleaning for a Maltese senior is more than scraping visible tartar.

Under general anesthesia:

• Full-mouth probing to chart pockets and attachment loss.
• Subgingival and supragingival scaling with ultrasonic and hand instruments.
• Polishing to smooth enamel and slow plaque re-accumulation.
• Oral radiographs to evaluate root and bone health.
• Extractions or endodontic treatment when indicated; local nerve blocks are used to minimize systemic analgesic needs.
• Antimicrobial therapy or culture-directed therapy if infection or abscess is present.

Why anesthesia? Multiple veterinary studies and position statements (AVDC, VOHC) note that non-anesthetic “cleanings” miss subgingival disease and are insufficient to treat periodontal disease properly. For small breeds where subgingival pockets form early, anesthesia with radiographs is the only reliable approach to detect and treat disease.

Anesthesia considerations specific to senior Maltese

Because Maltese can have MVD, collapsed trachea, and portosystemic shunts more frequently than many breeds, pre-anesthetic optimization is critical:

• MVD: Obtain a cardiac auscultation; consider echocardiography for murmurs. Coordinate with a veterinary cardiologist if moderate-to-severe disease is present. Individualized anesthetic protocols minimize changes in heart rate and blood pressure. Pimobendan or other cardiac meds should generally be continued as directed by a cardiologist.
• Portosystemic shunt / liver disease: Pre-anesthetic biochemistry is essential — liver dysfunction alters drug metabolism. Dose adjustments and drug selection should be made with hepatic impairment in mind.
• Collapsed trachea: Avoid excessive coughing and airway irritation; anesthetic induction and intubation should be performed gently, using appropriately sized tubes and possible pre-medications to reduce coughing.
• White shaker syndrome: If receiving corticosteroids or other immunosuppressants, risk of infection is higher and wound healing may be impacted. Communicate immunosuppressive status to your vet.
• Frailty and small size: Senior, low-body-weight patients need strict temperature, glucose, and blood pressure monitoring.

A personalized anesthetic plan, perioperative monitoring, local nerve blocks, and multimodal analgesia help reduce risk.

Treatment options and common procedures

• Non-surgical periodontal therapy: scaling and root planing (under anesthesia) to remove plaque and calculus from pockets.
• Extractions: Necessary when teeth are loose, fractured, or have severe root disease. Tooth extraction is a common component of dental surgery in Maltese due to small-jaw crowding.
• Pulp therapy/root canal: Considered for some fractured teeth — preserves the tooth and avoids extraction but requires specialized dental skill.
• Antibiotics: Not routinely used for uncomplicated cleaning; used when systemic infection, immunosuppression, or extensive extractions/osteomyelitis is present. Stewardship is important—follow your veterinarian’s guidance.
• Pain control: NSAIDs, opioids, and local nerve blocks commonly used. For dogs with liver disease, NSAID use may need special consideration; alternative analgesia or adjusted dosing may be necessary.
• Follow-up: Rechecks and repeat radiographs as indicated.

Preventing dental disease at home — practical, breed-specific tips

Daily prevention is the single most important action an owner can take to slow periodontal disease.

Daily toothbrushing

- Use a dog-formulated enzymatic toothpaste and a small soft brush or fingertip brush sized for toy breeds. - Start slowly: let your Maltese taste the paste, then gradually introduce brushing for a few seconds daily, building to a 1–2 minute total session. - Focus on the outside surfaces where plaque accumulates most; even 60–90 seconds daily can significantly reduce gingivitis.

Choose VOHC-accepted products

- Look for the Veterinary Oral Health Council (VOHC) seal on dental chews, diets, and rinses. Examples: specific small-breed dental chews and Hill’s Prescription Diet t/d. - For Maltese, select appropriately small chews to avoid choking and avoid very hard chews (rawhides, bones, antlers) that can fracture small teeth.

Water additives and oral rinses

- Enzymatic rinses and water additives can help reduce bacterial load; they are supplementary to brushing, not replacements.

Diet selection

- Veterinary dental diets that mechanically reduce plaque and calculus can be helpful between brushings. Discuss with your veterinarian whether a dental diet is appropriate given weight and medical conditions.

Regular visual checks

- Inspect the mouth weekly for bad breath, red/swollen gums, tartar, loose or missing teeth, and any facial swelling. - Keep a photo log if unsure whether findings are new.

Management of retained deciduous teeth

- If your Maltese has retained baby teeth as an adult, extraction at a younger age prevents crowding and later periodontal disease. For seniors, any retained teeth should be evaluated for disease.

Behavioral adaptations

- If your Maltese has luxating patella and reduced mobility, make brushing sessions comfortable (lap or table with non-slip surface) to minimize stress. - For dogs with white shaker syndrome, tremors may make home brushing challenging; work with your vet to time sessions when tremors are controlled and low-stress.

How often should a senior Maltese get professional cleaning?

Frequency depends on individual disease stage:

• Healthy mouths with excellent [home care](https://seniorpet.org/knowledge/pillar/home-care-guide "Senior Pet Home Care Guide"): professional exam and cleaning every 12 months.
• Mild to moderate periodontal disease: every 6–12 months.
• Advanced disease (bone loss, pockets, previous extractions): intervals determined individually—often every 3–6 months with periodic radiographs.

Table: Suggested dental maintenance schedule for a senior Maltese

| Intervention | Frequency (senior Maltese, 8–9 yrs) | Why | |--------------|-------------------------------------|-----| | Full oral exam + dental radiographs under anesthesia | Baseline at diagnosis; every 6–12 months depending on disease severity | Subgingival disease detection and treatment—critical in small-breed mouths | | Professional scaling & polishing | Every 6–12 months (sooner if disease advanced) | Removes subgingival calculus and treats pockets | | Home toothbrushing | Daily (aim for daily; minimum 3–4×/week) | Most effective way to slow plaque accumulation | | VOHC-approved chews/diet | Daily as adjunct | Reduces rate of calculus formation when used with brushing | | Oral recheck by veterinarian (awake) | Every 3–6 months | Monitor breath, gingiva, and functional issues between anesthesia events |

Interactions between dental disease and breed-specific conditions

• Mitral Valve Disease (MVD): Chronic bacteremia from severe periodontal disease can theoretically seed cardiac valves and complicate MVD. While infective endocarditis is uncommon, poor oral health increases systemic inflammatory load. Cardiac evaluation prior to anesthesia is recommended in Maltese with murmurs.
• Portosystemic liver shunt: Impaired hepatic clearance affects drug metabolism and immune competence. Pre-anesthetic bloodwork and dose adjustments are essential. Oral infections also pose greater systemic risk in these dogs.
• Collapsed trachea: Airway instability during induction and recovery requires careful anesthetic planning, using smaller, well-sized endotracheal tubes and smooth induction techniques.
• Luxating patella: Pain from dental disease can reduce mobility further; also consider that heavy sedation may temporarily affect limb function—plan post-anesthesia rest accordingly.
• Cataracts and vision impairment: Senior Maltese with poor vision may be more stressed during dental procedures and home care; keep routines calm and predictable.
• White shaker syndrome: Dogs receiving corticosteroids or other immunosuppressants are at higher infection risk. Communicate medications before dental work so perioperative infection control and antibiotic decisions can be individualized.

Practical, actionable checklist for owners of senior Maltese

Before the appointment:

• Gather your dog’s medical records (especially cardiac history, liver tests, medications such as corticosteroids or cardiac drugs).
• Note any cough, collapse, exercise intolerance, or seizure history.
• Ask your veterinarian about pre-anesthetic bloodwork and cardiac screening.

At home:

• Start a slow, daily toothbrushing routine with dog toothpaste and a small brush.
• Replace any hard chews that could fracture teeth with VOHC-approved soft dental chews sized for toy breeds.
• Keep a weekly photo log of the mouth—photos help the vet detect change.

When your vet recommends dental cleaning:

• Confirm that intraoral radiographs will be taken.
• Discuss anesthetic plan and how your dog’s other conditions (MVD, shunt, trachea) will be managed.
• Ask about local nerve blocks for pain control and a multimodal analgesia plan.
• Clarify antibiotic use policies and follow-up schedule.

Aftercare:

• Follow prescribed analgesic and antibiotic regimens closely.
• Soft food for 24–72 hours if extractions were performed.
• Monitor incision sites in the mouth and systemic signs of infection (fever, lethargy).
• Schedule rechecks as recommended.

When to call your veterinarian urgently

• Sudden facial swelling or draining tract (possible abscess).
• Refusal to eat for >24 hours or severe drooling.
• New or worsening cough in a dog with dental disease (possible aspiration or severe oral–respiratory connection).
• Any signs of systemic illness after dental procedures—fever, persistent lethargy, collapse.

Evidence and professional guidance

Professional veterinary dental organizations (AVDC, VOHC) and peer-reviewed literature emphasize:

• The necessity of anesthesia and intraoral radiographs for accurate periodontal assessment and treatment in dogs.
• The significant prevalence of periodontal disease in small-breed dogs and the benefits of daily home care to slow progression.
• The need to tailor anesthetic plans for small-senior dogs with cardiac, hepatic, or airway comorbidities.

A variety of studies in the Journal of Veterinary Dentistry and Journal of Veterinary Internal Medicine document the high prevalence of periodontal disease in toy breeds and highlight the systemic inflammatory implications. The VOHC maintains a list of tested products (toothpastes, chews, diets) with evidence of plaque/calculus reduction that can be used as adjuncts to brushing.

Final thoughts

For a Maltese entering senior years, dental care is one of the most impactful health-maintenance activities you can perform. Daily toothbrushing combined with periodic professional assessment and cleaning under anesthesia (with appropriate screening for MVD, liver shunts, and airway disease) will preserve comfort, maintain function, and reduce systemic risks. Work closely with your veterinarian—and if your Maltese has cardiac disease, hepatic issues, collapsed trachea, or is on immunosuppressants for white shaker syndrome—discuss individualized perioperative plans to keep dental care safe and effective.

Good dental health adds years of comfortable, pain-free smiles to your Maltese’s life. Start early, be consistent, and involve your veterinary team for the best outcomes.
