Repeated loss of upper front teeth

Hi,

one of our four piggies breaks off one or both of his upper front teeth relatively frequently (4 times within the last 6 months) but there does not seem to be a medical cause. We are at a loss as to why and how. We have found ways to manage the issue (frequent monitoring of gum health and regrowth, food cut into strips when he cannot bite things off properly) and we are lucky that he is smart about finding ways to eat and has a good appetite. However, we are wondering if we just have to accept that he just loses a tooth sometimes because he is being clumsy, or if there is anything we can do to prevent it.

The piggie is male, ca. 2 years old. He is a rescue and has been with us for a year now. He has been checked thoroughly and has no long-term health issues (besides his claws growing a bit wonky). We know that genetic or dietary issues can cause teeth to be particularly weak, but this does not seem to be the case here. Our pigs have a healthy diet (continuous access to hay and water, a generous serving of varied vegetables twice a day and nutritionally complete, grain-free, high-fibre pellets as an occasional hand-fed treat). Of course, we cannot exclude genetic issues or malnutrition in his youth, however, multiple vets have confirmed there does not seem to be anything wrong with his teeth. He has a good bite, the teeth grow evenly, they have a good colour, hardness etc. We even had an x-ray done and there is absolutely no sign of weak or porous teeth. Basically, it seems that his teeth are perfectly normal, he just somehow keeps managing to break them off.

The thing is, we don't know how this happens because we have never seen it, even though we monitor them pretty closely. Oddly enough, we have never even found a tooth fragment. He is not gnawing the metal bars of the enclosure and does not seem to be particularly clumsy. He very rarely climbs on things in the enclosure and we have never seen him fall down from or land clumsily when he does. All their furniture is wooden and safe to chew on (wood, cork, cardboard). He is the boss of his herd and sometimes has a small fight or chase with the runner-up, but these are resolved quickly and without injury, not serious enough to knock out a tooth. He does express himself through teeth-chattering more frequently than other piggies when he is annoyed at something, but not excessively or in a way that seems damaging. Our best guesses currently are that he pulls some extremely clumsy move in a fight, or that he runs into something, or chews on things in a really dumb way sometimes. Are there any potential explanations we are missing? Has anyone else had a similar problem with frequent loss of apparently healthy teeth? Is there a way to prevent it or at least mitigate the risk?
 
Hi and welcome

Unfortunately, there is not yet any working solution for guinea pigs who have a persistent issue with breaking incisors (upper or lower ones). You and your vet can consider suitable vitamin supplements but this area is sadly at this time not yet researched and understood and any approach is individual and experimental.
My elderly Hapus managed to snap her two lower incisors twice within a few weeks after they had grown back fully for the first time but thankfully not again in the last months of her life. Why she broke them and whether the problem did lie in a specific activity or a weakness in the teeth in combination with putting too much pressure on them could not be solved.

The incisors are about 4 cm long and curved; that makes them very prone to breaks. They are used mainly for picking up and cutting food but bar biting, falls etc. can sometimes cause a break. A single incisor can also break if there is a problem at the root but that is not to be considered in your case.

I wish I had better news. You are welcome to look at forum cases with a comparable issue via the Search button when you extend the top bar by clicking on the three horizontal lines icon if you feel that would help you.
 
Thank you! I wish there was something we could do, but overall it doesn't impact his quality of life very much.
Also, if there is anyone else finding this thread, it was super scary the first time it happened, but it's much less scary than it seems! Some things that we found work really well are:
- get one of those little dentist mirrors, they're pretty cheap. Much less stressful to check the teeth from below while the pig is sitting normally
- using a vegetable peeler to cut veggies into thin stripes
- grating veggies also works well, you can use the juice to make a paste with (high quality, grain-free) dry food to prevent weight-loss
- If the tooth breaks up in or very near the gums, flushing the with sage tea (mild disinfectant) twice a day prevents infection. Definitely go to the vet in that case, they might prescribe antibiotics pre-emptively. If a tooth breaks further down, you only need the vet later on to adjust uneven growth, but most of the time, the teeth readjust by themselves just fine if the pig has a healthy bite to begin with
 
thought I'd update this thread, we finally saw it happening and realised what the problem is (not that we can solve it lol)! We saw him briefly chase after another piggie, trying to run after him and threaten with his head raised at the same time. He very inelegantly missed the entrance to the ramp, running teeth first into the doorframe. He's not the most athletic pig to begin with and apparently loses all coordination when he gets flustered. There's a chance that his eyesight isn't great, but he navigates new surroundings just fine, so it can't be that bad. It's mainly just him losing his head. It's a relief to know that it's not an inherent problem with his teeth, just him being dumb when asserting dominance sometimes. Not much we can do short of taking away all the hideys, so we just hope he learns from his mistakes eventually. At least he's figured out how to eat leafy vegetables without using his front teeth.

It looks like it could be down to a sight issue. But you must be relieved that it is not a dental problem.

We're definitely keeping an eye on his eyesight. It's enough to navigate and explore under normal circumstances, but it might still be too poor for accurately assessing distances when he's distracted and running. Hard to tell. Going forward, we'll avoid changing the cage layout in high-traffic areas just in case. That said, the entrance to the ramp he ran into has been in the exact same spot for 6 months now, so there clearly is an element of plain clumsiness that unfortunately isn't helped by knowing where things are.

Could you pad the crucial area on the ramp side with some thicker fleece wadding? That should prevent the teeth from snapping again.

Blind guinea pigs have their own mental map based on scent, touch, feel (whiskers and paws) and hearing - all senses that are much stronger than their human equivalent. Sight is our strongest but the weakest sense in guinea pig. As long as you do not deep clean and allow the smelly furniture and scent retaining ramp flooring to be still there after a move for orientation, blind piggies can deal well with any changes to a layout; they are wired to follow scent spoors.

It may be more of an attention focus issue.
