Dental care is just as important for our small pets as it is for dogs and cats. After all, they deserve to have a winning smile too! And a little knowledge goes a long way when it comes to healthy rabbit teeth, healthy guinea pig teeth and healthy hamster teeth. Our in-house vet Dr Suzanne Moyes has all the tooth care details you need to know.

Q: What’s the difference between small pet teeth and the teeth of dogs and cats?

A: Unlike dogs and cats (and us!), who have baby teeth that are then replaced by adult teeth, small pets have just one set of teeth throughout their life. What’s more, their teeth act rather differently. Rabbits, guinea pigs, chinchillas and degus have teeth that all grow continuously. Hamsters, gerbils, rats and mice have front teeth that continuously grow, while their back teeth stop growing after a certain age. 

Q: What are the main teeth problems that small pets can suffer with?

A: Because their teeth grow continuously, a common problem is overgrown or misaligned teeth, which is known as malocclusion. This can be extremely painful for small pets. The teeth at the front (the incisors) can curl round at an odd angle, which can cause damage to the mouth and tongue. If the back teeth (the molars) become overgrown, this can lead to sharp spurs forming. These can cause sore cuts to the tongue and cheeks which leads to problems with swallowing and may form into abscesses – painful pockets of pus caused by a bacterial infection.

Q: How can you tell if a small pet has a problem with their teeth?

A: Apart from visible signs that teeth are overgrown or sticking out at funny angles, other telltale signs include drooling, weepy eyes, facial swelling, a runny nose, teeth grinding, fewer or smaller droppings than usual and a reluctance to eat. Loss of appetite is a big red flag because small pets such as rabbits and guinea pigs rely on near-constant grazing to keep their digestive system functioning properly or they can develop gut stasis. This is a condition where their digestive system slows down or stops, resulting in a build-up of gas and toxins which can be fatal. If your small pet stops eating, it’s an emergency and you need to contact your vet immediately.

Q: What causes teeth problems in small pets?

A: The most common cause is incorrect feeding. Small pets with continuously growing teeth require a high fibre diet. If their diet is too low in fibre, their teeth don’t get worn down and grow too long. This makes eating difficult and, consequently, affects their overall health.

Q: What are the best ways to help small pets have healthy teeth?

A: For rabbits, guinea pigs, chinchillas and degus, the solution is simple – feed them lots of high-fibre feeding hay – their own body size in hay every day. The action of chewing fibrous hay wears their teeth down evenly, keeping their teeth properly worn in the way nature intended. High quality Timothy hay is ideal as small pets find it very satisfying to chew on. 

For hamsters and gerbils, providing them with plenty of things for them to gnaw on, such as safe fruit tree twigs, cardboard tubes and woven willow or seagrass balls, is a healthy-teeth essential. 

Rats and mice wear their teeth down naturally by grinding their teeth together, which is known as ‘bruxing’, but they can still suffer from oral health issues, such as overgrown incisors, so if you notice any changes in behaviour or eating habits, always consult your vet.

Q: What else can I do to help my small pets keep their teeth healthy?

A: Always ensure you provide the right diet for your rabbits, guinea pigs, chinchillas and degus, hamstergerbils, rats or mice. Depending on what pets you have, this should include hay-quality feeding hay, fresh crunchy vegetables and nutrition-packed nuggets

Give your small pets a spacious, enriching environment, with lots of things to investigate and plenty of suitable chewing materials. Bored pets can gnaw on the side of their cage which can cause teeth to get damaged, so keeping them stimulated and offering enrichment to their lives will help prevent this.

Take your small pet to a specialist vet for regular check-ups – at least once a year. There are various treatments available to help small pets with their teeth should problems occur. Dental issues are very manageable if they’re caught early.

KNOW THESE SIGNS OF HEALTHY TEETH IN YOUR SMALL PETS

  • Rabbit and guinea pig teeth should be pearly white or creamy off-white.
  • Hamster and gerbil teeth should be a light yellow colour, although they can be white when they’re very young.
  • Chinchillas and degu teeth should be dark orange in colour.
  • Mice should have yellow teeth while rats have orange-yellow teeth, which may get darker as they age.
