Let’s Talk About Teeth 🦷 (And Hay!)
How chewing hay helps your pet’s dental health

When it comes to rabbits and guinea pigs, one of the most important things to know is that their teeth never stop growing. That’s right, from the day they’re born until the end of their lives, their teeth keep on moving. Without the right diet, this can quickly lead to painful problems.
Luckily, there’s a simple, natural solution: hay. Chewing hay is the best way to keep those teeth in perfect shape. Let’s explore why.
Why Dental Health Matters
Overgrown teeth can cause serious health issues for small pets, including:
- Difficulty eating and weight loss
- Pain and sores in the mouth
- Misaligned teeth (malocclusion)
- Risk of infections
That’s why prevention is always better than cure, and hay is the number one preventative.

Hay: Nature’s Toothbrush
Every mouthful of hay works like gentle sandpaper, wearing teeth down to the correct length. Unlike pellets or soft veggies, hay requires hours of chewing every single day. This constant grinding action naturally manages tooth growth, keeping edges smooth and healthy.
The Right Amount of Hay
Rabbits and guinea pigs should eat a pile of hay about the same size as themselves every day. Here’s how to make sure they get enough:
- Keep hay racks and litter trays topped up at all times
- Refresh hay daily to keep it fragrant and inviting
- Offer different cuts of hay for variety and enrichment

Signs Your Pet May Have Dental Issues
Even with hay in the diet, problems can still arise. Watch out for:
- Drooling or a wet chin
- Reduced appetite or food falling from the mouth
- Weight loss
- A preference for softer foods
- Changes in behaviour such as hiding or irritability
If you spot any of these, contact your vet promptly.
Supporting Healthy Teeth Beyond Hay
While hay is the foundation of dental health, you can add extra support through:
- Safe chew toys made from natural wood
- Fresh leafy greens for variety
- Regular health checks to catch issues early
