Overview

  • Have you noticed your rabbit grinding their teeth?
  • Depending on how your rabbit is grinding his/her teeth, it could be a sign of pain/illness/distress (loud grinding), or happiness and contentment (quiet, soft grinding)!

  • Contact your vet urgently if you think your rabbit is in pain, especially if their tooth grinding started suddenly and/or they are showing any other symptoms such as drooling, a reduced appetite or low energy.

When to contact your vet

It’s always best to contact your vet if your rabbit has started grinding his/her teeth, and it’s important to act quickly if your rabbit seems to be in pain, isn’t eating as much as normal, or is showing any other symptoms such as drooling or low energy. If possible, film your rabbit grinding their teeth to show your vet - even if it turns out to be normal natural tooth grinding, it’s better to be safe than sorry.

Other symptoms to look out for
