Guinea Pig Malocclusion - Peaches' Story

Guinea Pig Malocclusion Peaches Story 

 When a guinea pig stops eating normally, you know there's something wrong. The first warning sign came when Peaches didn't scarf down her blueberry right away. Confused by her uncharacteristic lack of enthusiasm, I peered at her as she took her time chewing, making unusual jaw movements as if she was trying to dislodge food from between her teeth.

I watched her closely through the next several mealtimes with increasing apprehension. On Monday she was gobbling down grass with gleeful gusto. By Wednesday she was struggling to snip even the thinnest blades. A visit to the vet confirmed my suspicions: malocclusion.


WHAT IS MALOCCLUSION?

Guinea pigs have open-rooted dental systems - meaning, their teeth are constantly growing throughout their lifetime. This continuous growth makes them more susceptible to malocclusion, a condition where overgrown teeth and other dental anomalies prevent the cavy from being able to eat and chew food normally.


COMMON SYMPTOMS
  • Difficulty chewing
  • Difficulty ripping food with teeth
  • Drooling, present as wet fur around the mouth and chin
  • Inability to completely close the mouth
  • Incisor overgrowth
  • Eating at a slower than normal pace
  • Decreased appetite, shows interest in food but is unable to eat 
  • Preference for soft foods
  • Weight loss
  • Facial abscesses
  • Eye discharge

In Peaches' case symptoms presented as difficulty chewing, difficulty tearing at food, and chewing at a slower pace. She displayed her usual interest in food but had trouble eating it. Being the diva pig that she is, Peaches repeatedly demonstrated her frustration by picking up food in her mouth, waving it about, and pawing the air before dropping it and repeating the process again.

Peaches Malocclusion Incisors

PEACHES' TREATMENT

Peaches underwent an oral exam and dental trim under anesthesia. During the procedure our vet discovered that her bottom left incisor was growing in twice as thick as the right. Her incisors were trimmed and her molars were filed down slightly with a dental bur.


POST-OPERATIVE CARE

Peach was prescribed Metacam for inflammation and pain relief.

To encourage her to eat, we brought out all her favorite foods. While in a drug-induced haze she began to take nibbles here and there. To make it easier for her we trimmed long strands of hay short, cut greens and vegetables into half-centimeter size pieces, curled lettuce leaves into rolls, and provided fresh grass. We hand fed her and supplemented her diet with Oxbow Critical Care.

After the pain meds from the procedure fully wore off Peaches completely lost her appetite. Because of the dental discomfort she was no longer willing to even consider eating on her own. Worried about gastrointestinal hypomotility, the piggy dad and I began syringe feeding her every 4-6 hours to keep her digestive tract moving. After a consultation with our vet, Cisapride was prescribed to aid motility.

We hope Peaches feels better soon. I'm sure she's getting sick of all those syringes.

  2. I'm not sure, I wondered that too. That photo was taken the day she came home, so it could have been due to the work she had done. She's nowhere near willing to let anyone get a look at her mouth now but I'm bringing her back in for a recheck later this afternoon.

  3. Poor Peaches :( Are gums normally that red-pink or are hers inflamed and red? I really hope she feels better soon! Sending lots of good wishes to all of you.

  4. We had this problem with Perky, about two years ago. He also stopped drinking, and made a 'clacking' noise. I had to sit up all night with him, keeping him warm and using a syringe to get water into him, before we could take him to the vet the following day.

    Get well soon Peaches. xxx

  7. No fun. I hope Peaches recovers quickly and gets back to her diva self. Those teeth are so short!

    Nice post. I like how you laid out the information for each step of the process.

  8. Thank goodness she pulled through and is eating a bit again. It sounds
    like it will take time, but I am just so glad to hear that she is
    improving. *HUGS* to both of you.

  9. Peaches says thanks for the well wishes Michelle! After 4 straight weeks of Critical Care she's starting to eat small bits of herbs when being hand fed. No such luck with hay though.. she has to re-learn how to eat with her thickened front incisors.
