Guinea pig stopped eating hay but eats pellets. Is it dental pain?

Pet's info: Other | Unknown - Other | Female | unspayed | 4 years and 1 month old

My guinea pig has always eaten timothy hay like crazy but for the past couple months she has pretty much stopped eating it completely. She still eats her pellets like normal, eats her vitamin C tablet and eats any fresh fruits/veggies I give her but she won't really eat any timothy hay anymore. What could be the cause of her lack of interest in hay? Is it something I should be taking seriously?

Thanks for reaching out about Lucy. Dental disease (cheek teeth) are fairly common in guinea pigs, as their teeth grow throughout life. Infections, inflammation, scurvy, can all be causes. Dental disease can be infections or inflammation, and therefore painful. If it hurt to chew, and hay requires more chewing, then she might be shying away from hay. A veterinary visit is recommended to check, more important if you think she is loosing weight. Good luck.
