How to Clean Your Cat’s Teeth 🐱✨

By Dr Duncan Houston

🔎 Quick Answer

Dental disease is extremely common in cats and often goes unnoticed until it is advanced and painful. Signs include bad breath, red gums, drooling, and difficulty eating. Regular tooth brushing is the best way to prevent plaque and gum disease at home, but many cats will still require professional dental treatment under anaesthesia if disease is already present.

Cats are incredibly good at hiding pain.

Which is why dental disease in cats often flies under the radar for a long time.

They keep eating.
They act mostly normal.
And meanwhile… their mouth can be seriously painful.

🦷 Why Dental Disease in Cats Matters

Dental disease is one of the most common conditions I see in cats.

By the age of 3:

👉 a large percentage of cats already have some degree of dental disease

This can include:

• plaque and tartar buildup

• gingivitis (gum inflammation)

• periodontal disease

• tooth resorption (very common and painful in cats)

👉 This is not just about bad breath.

Dental disease can cause:

• chronic pain

• infection

• tooth loss

• difficulty eating

• reduced quality of life

🔍 Signs Your Cat May Have Dental Disease

Cats rarely make it obvious.

Look for:

• bad breath

• red or bleeding gums

• yellow or brown tartar

• drooling

• pawing at the mouth

• chewing on one side

• dropping food

• reduced appetite

• weight loss

• hiding or behaviour changes

👉 Subtle changes matter.

⚠️ Common Dental Problems in Cats

Gingivitis

• inflammation of the gums

• often the first stage of disease

Periodontal Disease

• infection below the gumline

• leads to bone loss and loose teeth

Tooth Resorption

Very common in cats.

• the tooth structure breaks down

• extremely painful

• often requires extraction

👉 Many cats suffer from this without obvious signs.

Stomatitis

• severe inflammation of the mouth

• painful, often chronic

• may require aggressive treatment

🧼 Can You Clean a Cat’s Teeth at Home?

Yes… but it depends on the cat.

Some cats tolerate brushing well.
Some act like you’ve declared war.

👉 The earlier you start, the easier it is.

🪥 How to Brush Your Cat’s Teeth

Step 1: Start slowly

Do not go straight in with a toothbrush.

Start with:

• gentle face handling

• lifting the lips

• touching the gums

Reward calm behaviour.

Step 2: Introduce toothpaste

Use cat-safe toothpaste only.

Let your cat:

• lick it from your finger

• get used to the taste

Flavours are usually meat-based and more appealing.

Step 3: Use a soft brush or finger brush

Start with:

• a finger brush

• or a small, soft toothbrush

Focus on the outer surfaces of the teeth.

Step 4: Short, gentle sessions

• small circular motions

• focus on back teeth

• keep sessions brief

👉 Even a few seconds is a good start.

Step 5: Build consistency

You are aiming for:

• daily brushing ideally

• or a few times per week

👉 Consistency beats perfection.

🚫 Common Mistakes

• using human toothpaste

• forcing the mouth open

• going too fast

• expecting full brushing on day one

• giving up after one bad attempt

👉 This is training, not just brushing.

🦴 What If My Cat Won’t Tolerate Brushing?

Not every cat will allow it.

Other options can help support dental health:

• dental diets

• dental treats

• water additives

• dental gels

👉 These help, but they are not as effective as brushing.

🩺 Professional Dental Cleaning

If dental disease is already present, brushing alone is not enough.

Your cat may need a professional dental procedure under anaesthesia.

This allows:

• full oral exam

• scaling and polishing

• cleaning below the gumline

• dental X-rays

• tooth extractions if needed

👉 This is often the only way to properly treat established disease.

🧠 Why Cats Hide Dental Pain

Cats instinctively hide weakness.

That means:

• they keep eating despite pain

• they adapt their chewing

• they become quieter rather than dramatic

👉 By the time signs are obvious, disease is often advanced.

🏠 Practical Tips for Better Dental Health

• start dental care early in life

• use wet and dry food appropriately

• monitor breath and eating behaviour

• schedule regular vet checks

• act early if something changes

🐾 Practical Takeaways

• dental disease is extremely common in cats

• cats hide oral pain very well

• brushing is the best at-home prevention

• not all cats tolerate brushing

• many cats still need professional dental treatment

💬 Final Thoughts

Dental disease in cats is one of the most under-recognised sources of pain.

They do not complain.
They do not make a fuss.
They just live with it.

And that is exactly why it matters.

A little prevention at home, combined with early intervention when needed, can make a huge difference to your cat’s comfort and long-term health.
