Dental Disease in Cavalier King Charles Spaniels
Dental Disease: Protecting Your Cavalier's Teeth, Gums and Overall Health
A beautiful smile is lovely, but healthy teeth are about much more than appearance.
Dental disease is one of the most common health problems affecting dogs, and Cavalier King Charles Spaniels can be particularly susceptible to periodontal disease. Research into dogs attending primary-care veterinary practices found that Cavalier King Charles Spaniels had significantly increased odds of periodontal disease compared with crossbred dogs.
Dental disease can cause pain, inflammation, infection and, in advanced cases, loss of the tissues supporting the teeth. The good news is that regular home dental care, veterinary examinations and appropriate professional treatment can help protect your Cavalier's oral health throughout life.
What Is Dental Disease?
"Dental disease" is a broad term that can describe several problems affecting the teeth, gums and surrounding tissues. One of the most common is periodontal disease.
Periodontal disease affects the structures surrounding and supporting the teeth. It develops when plaque accumulates on the teeth and contributes to inflammation of the gums and, as the disease progresses, damage to the tissues and bone supporting the teeth.
Dental disease can progress gradually, and dogs do not always show obvious signs of discomfort. This means your Cavalier may have significant dental disease before you realise there is a problem.
Why Are Cavaliers Prone to Dental Disease?
Cavalier King Charles Spaniels are a relatively small breed, and small dogs are generally at greater risk of periodontal disease than larger dogs.
Research involving more than 22,000 dogs found that smaller body size was associated with increased risk of periodontal disease, while Cavalier King Charles Spaniels were among the breeds with the highest increased odds.
The same research found that the risk of periodontal disease increased with age. This makes proactive dental care particularly important for Cavaliers, rather than waiting until dental problems become obvious.
Plaque, Tartar and Periodontal Disease: What's the Difference?
Understanding the terminology can help you recognise what is happening inside your Cavalier's mouth.
Plaque
Plaque is a sticky film containing bacteria that forms on the teeth.
If plaque is not removed, it can contribute to inflammation of the gums.
Tartar
Tartar, also called calculus, develops when plaque mineralises and hardens on the teeth.
It is much harder to remove than soft plaque.
Gingivitis
Gingivitis is inflammation of the gums.
The gums may appear red, swollen or bleed easily.
At this stage, appropriate treatment and improved oral hygiene may help prevent progression.
Periodontitis
Periodontitis is more advanced periodontal disease involving damage to the tissues supporting the teeth.
As periodontal disease progresses, there can be loss of attachment and bone supporting the teeth, eventually resulting in loose teeth and tooth loss. This is why dental care should begin before significant tartar or periodontal disease develops.
What Are the Signs of Dental Disease?
Some Cavaliers with dental disease show very few obvious signs.
Others may develop:
Bad breath
Yellow or brown tartar
Red or swollen gums
Bleeding gums
Excessive drooling
Difficulty eating
Chewing on one side of the mouth
Reluctance to eat
Dropping food
Loose teeth
Missing teeth
Pawing at the mouth
Facial swelling
Changes in behaviour
Bad breath should not simply be dismissed as "normal dog breath". Persistent bad breath can be a sign of dental disease and should be discussed with your veterinarian.
Dental Disease Can Be Painful
Dogs are remarkably good at continuing their normal routines despite discomfort.
A Cavalier with painful teeth may still:
Eat normally
Play normally
Seek affection
Go for walks
Appear happy
This does not necessarily mean their mouth is comfortable. Advanced periodontal disease can involve inflammation, infection, loss of supporting bone and painful dental structures.
Dogs don't always stop eating simply because their mouths hurt. Regular veterinary dental examinations are therefore important even when your Cavalier appears perfectly well.
Why Dental Care Matters for Your Cavalier
Untreated periodontal disease can cause progressive damage to the structures supporting the teeth. The Australian Veterinary Association notes that untreated oral disease can be painful and may contribute to local or systemic disease.
For your Cavalier, maintaining good oral health is therefore about:
Comfort.
Eating.
Healthy gums.
Healthy teeth.
Quality of life.
And helping prevent avoidable dental pain.
How to Check Your Cavalier's Teeth at Home
Get into the habit of looking inside your Cavalier's mouth regularly.
Gently lift the lips and look for:
☐ Plaque
☐ Tartar
☐ Red or swollen gums
☐ Bleeding
☐ Broken teeth
☐ Loose teeth
☐ Missing teeth
☐ Unusual swelling
☐ Discolouration
☐ Bad odour
Don't force your Cavalier to open their mouth if they are uncomfortable.
Instead, gradually teach them that having their mouth examined is a normal and positive part of life.
Brushing Your Cavalier's Teeth
Tooth brushing is one of the most effective forms of home dental care. The Royal Veterinary College's VetCompass research recommends good dental care, including tooth brushing with a dog-specific toothpaste, from a young age.
Ideally, introduce tooth brushing when your Cavalier is young. However, it is never too late to begin teaching an older dog to accept gentle dental care.
Start slowly:
Allow your Cavalier to become comfortable with you touching their mouth.
Introduce the toothbrush gradually.
Allow them to taste a dog-specific toothpaste.
Begin with just a few teeth.
Gradually increase the duration.
Keep the experience positive.
Aim for regular brushing.
Never use human toothpaste for your dog unless specifically advised by your veterinarian.
What About Dental Chews?
Some dental chews and dental diets can form part of an oral-care routine. However, they should complement, not replace, regular tooth brushing and veterinary care.
The Australian Veterinary Association recommends that veterinarians develop an individualised home-care plan that may include brushing, appropriate dental chews, special foods or other products depending on the individual animal.
The Veterinary Oral Health Council (VOHC) evaluates certain products for their ability to help control plaque and/or tartar, and the AVA encourages veterinarians to recommend appropriate accepted products where suitable. Ask your veterinarian which dental products are appropriate for your Cavalier.
Why "Anaesthesia-Free" Dental Cleaning Is Not the Same as Veterinary Dental Treatment
This is an important distinction for dog owners. You may see services advertising dental cleaning without anaesthesia. However, simply scraping visible tartar from the surface of the teeth does not address disease below the gum line.
The Australian Veterinary Association states that a complete dental examination requires the patient to be appropriately anaesthetised so that the veterinarian can perform procedures such as periodontal probing and dental radiographs.
Cleaning only the visible part of the tooth may improve its appearance while leaving disease underneath the gum line untreated. A clean-looking tooth is not necessarily a healthy tooth.
What Happens During a Professional Dental Procedure?
If your veterinarian recommends a professional dental procedure, the process may involve:
A pre-anaesthetic assessment
General anaesthesia
Examination of the mouth
Dental charting
Periodontal probing
Removal of plaque and calculus above and below the gum line
Dental radiographs where appropriate
Treatment of diseased teeth
Extractions where necessary
Polishing
Development of an ongoing home-care plan
The Australian Veterinary Association recommends comprehensive oral examination and notes that intra-oral radiographs are highly recommended. The exact procedure will depend on your Cavalier's individual dental health.
What About Cavaliers With Heart Disease?
This is particularly important for Cavalier King Charles Spaniels because mitral valve disease is a significant breed health concern. A Cavalier with a heart murmur or diagnosed heart disease may require additional assessment before undergoing anaesthesia. This does not mean that dental disease should simply be left untreated. Instead, your veterinarian should assess your Cavalier's overall health and determine the safest approach.
For example, a Queensland veterinary case involving an older Cavalier with severe periodontal disease and a significant heart murmur required cardiac assessment before dental treatment.
If your Cavalier has:
A heart murmur
Diagnosed mitral valve disease
Previous anaesthetic complications
Other significant health problems
tell your veterinarian before any dental procedure is scheduled.
Puppies Need Dental Care Too
Dental care should begin early. Puppies need to learn that having their mouth handled, their teeth examined and their teeth brushed is a normal part of life. Starting early can make dental care much easier as your Cavalier grows.
Your veterinarian can also monitor the development and eruption of the adult teeth and identify any abnormalities that may require attention. Don't wait until your puppy has tartar before introducing dental care.
Dental Care for Older Cavaliers
Dental health becomes increasingly important as your Cavalier ages. Research has found that the risk of periodontal disease increases with age.
Older Cavaliers should therefore have their mouths monitored carefully for:
Increasing tartar
Gum disease
Loose teeth
Tooth loss
Changes in eating
Bad breath
Mouth pain
Your veterinarian can advise how frequently your older Cavalier should receive dental examinations.

Dental disease can progress without obvious symptoms, so early assessment is always preferable.
Healthy Teeth Are Part of a Healthy Cavalier
Your Cavalier's dental health deserves the same attention as their heart, eyes, ears, joints and overall wellbeing. Dental disease is common in dogs and is particularly relevant to Cavalier King Charles Spaniels. Research has identified the breed as having increased odds of periodontal disease, with risk increasing as dogs grow older.
The best approach is preventative: Look. Brush. Check. Treat. Repeat.
By making dental care part of your Cavalier's normal routine from an early age, you can help protect their teeth and gums and, importantly, help prevent unnecessary dental pain. Your Cavalier gives you a lifetime of love. Their smile deserves a lifetime of care, too.
