Guinea pig teeth grow constantly throughout their life and if they are not being worn down by chewing on lots of hay or grass they start to elongate. The most common form of dental disease in guinea pigs involves the elongation of their cheek teeth. The mandibular cheek teeth are often the worst affected and they can get so bad that they can grow over and totally ‘entrap’ the tongue. This prevents the tongue from moving normally which means the guinea pig cannot eat properly.
