Why Is My Cat Missing Teeth? Top 5 Reasons

Why Is My Cat Missing Teeth? The top 5 Reasons include dental disease, injury, genetics, age-related loss, and infections affecting your cat’s dental health.

Why Is My Cat Missing Teeth?

Dental problems in cats are more common than many pet parents realise. If you’ve noticed your cat has missing teeth, you may be wondering what caused it and whether it’s a serious concern.

Understanding why your cat is missing teeth is essential, as it can reveal underlying health problems and help you take steps to protect their overall well-being.

Reasons for Missing Teeth in Cats

Reason	Explanation	Key Signs
Periodontal Disease	Plaque hardens into tartar, causing gum infection and tooth loss.	Bad breath, red/swollen gums, and pain when eating
Tooth Resorption	Teeth break down and are absorbed by the body, a common occurrence in aging cats.	Missing teeth, pain, sometimes no visible damage
Injury/Trauma	Fights, falls, or accidents can fracture or knock out teeth.	Swelling, bleeding, and reluctance to eat
Age-Related Changes	Older cats face gum disease, weak roots, and natural tooth loss.	Tooth loss in seniors, difficulty chewing
Dietary Factors	Soft/processed food and poor nutrition increase plaque and weaken oral health.	Plaque buildup, weaker teeth
Genetic Predisposition	Certain breeds (Abyssinians, Siamese, Persians) are more prone to dental disease.	Early tooth loss despite care

1. Dental Disease

a).Periodontal Disease
Periodontal disease is a common concern for cats, beginning with plaque that can develop into tartar, which may cause gum inflammation. Over time, the infection weakens the structures supporting the teeth, leading to tooth loss. Signs include bad breath, red or swollen gums, and discomfort while eating.

b) Tooth Resorption
Tooth resorption is a painful condition where a cat’s tooth gradually breaks down and is absorbed by the body. This process can affect one or multiple teeth, often leading to missing teeth without apparent external damage. It’s very common in cats, especially as they age.

2. Injury or Trauma

• Cats’ curiosity and activity can lead to dental injuries.
• Common causes include fights, falls, or accidents.
• Injuries may result in fractured or knocked-out teeth.
• Signs of trauma include swelling, bleeding, or refusal to eat.

3. Age-Related Changes

• Cats, like humans, experience dental changes as they age.
• Senior cats are more prone to gum disease.
• Tooth roots may weaken over time.
• As cats age, they are more likely to experience natural tooth loss.
• Regular dental care is crucial for maintaining oral health in senior cats.

4. Dietary Factors

• A poor diet can lead to dental problems in cats.
• Soft or processed foods increase plaque buildup.
• Lack of essential nutrients weakens oral health.
• A balanced diet supports stronger teeth and gums.
• Dental-friendly treats or kibble help maintain oral hygiene.

5. Genetic Predisposition

• Certain cat breeds are genetically more prone to dental issues.
• Abyssinians, Siamese, and Persians are at higher risk.
• Conditions may include tooth resorption and gum disease.
• Hereditary factors can cause early tooth loss.
• Dental problems may occur even with proper care.

Causes of Missing Teeth in Cats

Cause	What It Means	Signs to Watch For
Periodontal Disease	Gum infection from plaque and tartar	Bad breath, drooling, trouble chewing
Tooth Resorption	Tooth breaks down from the inside	Missing teeth, pain, may need X-rays
Trauma	Teeth lost from falls, fights, or accidents	Swelling, bleeding, and refusing food
Stomatitis	Severe inflammation in the mouth	Red gums, drooling, weight loss, pain
Abscesses/Decay	Infection or severe tooth decay	Pus, bad smell, facial swelling
Note	Missing teeth in adult cats	Always get a vet checkup

Symptoms to Monitor

If your cat is missing teeth, watch for other warning signs of dental issues:

• Persistent bad breath
• Difficulty chewing or dropping food
• Excessive drooling
• Pawing at the mouth
• Visible swelling or oral pain

When to Consult a Veterinarian

Contact your veterinarian if you notice sudden tooth loss, bleeding, or difficulty eating. Even one missing tooth can signal a larger dental problem. Regular dental checkups enable early detection and treatment, which helps prevent more serious complications.

Preventive Care for Dental Health

The best way to prevent tooth loss in cats is proactive care:

• Brush your cat’s teeth regularly with feline-safe toothpaste
• Provide dental treats or chews designed to reduce plaque
• Schedule professional cleanings as recommended by your vet
• Offer a balanced diet that supports oral health
