Why Tennis Balls Are Bad for Dog Teeth 🦷🎾

By Dr Duncan Houston

Quick Answer

Tennis balls can damage your dog’s teeth because the fuzzy outer surface acts like sandpaper, especially once it collects dirt and grit. They can also become a choking or airway obstruction risk. Safer alternatives are smooth rubber or silicone fetch toys that are properly sized and not overly hard.

If your dog loves tennis balls, you’re not alone. It’s one of the most common toys I see — and one of the most misunderstood.

They look harmless… but over time, they can quietly cause significant dental damage and even pose a serious choking risk.

The goal isn’t to stop fetch. It’s to make it smarter.

🧠 Why Tennis Balls Are a Problem

There are two main issues:

🦷 Dental wear
💨 Airway/choking risk

The fuzzy felt coating slowly grinds teeth down, while the ball itself can split, compress, or get lodged in the throat.

Dogs that chew, clamp, or obsessively carry balls are at the highest risk.

🦷 How Tennis Balls Wear Teeth Down

The outer fuzz of a tennis ball is designed to be rough and durable.

That’s great for tennis… not for teeth.

Over time:

• The felt acts like sandpaper
• Dirt and sand get trapped in the surface
• Repetitive chewing increases friction
• Enamel gradually wears away

Once enamel is gone, it does not grow back.

This leads to the classic flattened, worn-down teeth we see in heavy fetch dogs.

🚩 Signs of Tennis Ball Tooth Wear

Look for:

• Flattened or blunted teeth
• Darker areas (exposed dentin)
• Sensitivity when chewing
• Dropping toys or hesitation
• Bad breath or staining

If your dog suddenly becomes less enthusiastic about fetch… it may not be laziness. It may be pain.

💥 Other Dental Injuries

Tennis balls don’t just wear teeth down — they can also cause:

• Fractured teeth
• Cracked enamel
• Pulp exposure (very painful)
• Infection requiring extraction or root canal

Dogs with strong jaws can crush balls, increasing both dental and choking risks.

🐕 Which Dogs Are Most at Risk

Higher-risk dogs include:

• Retrievers and fetch-obsessed breeds
• Shepherds and working dogs
• Bull breeds and strong chewers
• Terriers that love to destroy toys

But honestly — any dog that chews regularly on tennis balls is at risk.

⚠️ Choking and Airway Risk

This is the part people underestimate.

A tennis ball can:

• Compress in the mouth
• Slide toward the throat
• Re-expand and block airflow

This is a true emergency.

🚨 Signs of Choking

Get immediate help if you see:

• Pawing at the mouth
• Gagging or retching
• Difficulty breathing
• Panic or distress
• Blue or pale gums
• Collapse

Even if the ball comes out — your dog still needs to be checked.

✅ Safer Fetch Alternatives

You don’t need to stop playing — just upgrade the equipment.

Look for:

• Smooth rubber or silicone balls
• No fuzzy coating
• Slight flexibility (not rock hard)
• Bright colors for visibility
• Durable, non-toxic materials

🛍️ What to Look For in a Safe Fetch Toy

Size matters

Choose a ball larger than your dog can fit behind their tongue

Material matters

Avoid:

🚫 Fuzzy surfaces
🚫 Ultra-hard materials
🚫 Cheap plastics

Use the thumbnail test
If you can’t dent it slightly → too hard

Condition matters

Replace toys when:

• Cracked
• Flattened
• Losing structure

🔄 If Your Dog Is Tennis-Ball Obsessed

Don’t go cold turkey. Transition smart.

Step 1

Remove free access to tennis balls

Step 2

Introduce a safer fetch toy

Step 3

Reward the new toy heavily

Step 4

Limit chewing time

Step 5

Teach a strong “drop” command

🎓 How to Make Fetch Safer

Small changes make a big difference:

• Supervise play
• Avoid long chewing sessions
• Encourage ground pickups over air catches
• Use one toy at a time
• Rotate toys to reduce obsession

🪥 Protecting Teeth Long-Term

Fetch is only part of dental health.

Also include:

• Daily brushing
• Regular dental checks
• VOHC-approved dental products
• Monitoring for early wear

If your dog already has wear — this becomes even more important.

🐾 Final Thoughts

Tennis balls seem harmless, but they’re not designed for dogs.

Over time they can:

🦷 Wear down teeth
💥 Cause fractures
💨 Create choking emergencies

The fix is simple:

➡️ Swap to safer toys
➡️ Size them correctly
➡️ Supervise play

Your dog still gets the fun — without the long-term damage.
