Hmm, quite young, must have been 3–4.
The first extraction was the final, they all came out. The vet offered us the choice of taking them out piecemeal or at once. Apparently it's intractable and was already affecting most of her teeth, so they'd likely all come out in the end, but she'd have years of discomfort and multiple surgeries to get there. Given it involves general anaesthetic and LMC really, really doesn't like going to the vet, we opted for the single surgery and out they all came.
I don't believe there's anything you can do to stop it. If it's only affecting a few teeth, the vet may feel it's best just to remove those affected and see what happens to the rest. But any surgery under GA is traumatic and contains an element of risk.
That said, if she's bothered by the fact, she's not said. Honestly, she doesn't seem to realise. She still gums the occasional mouse.
