Pippi is only 3 - at her annual checkup last year the vet commented on how bad her teeth & gums were for her age, but this year's vet had a closer look, noticed some teeth are already missing & advised total extraction as the best treatment - otherwise her mouth will get more & more painful & she'll eventually stop eating 
Cost estimate was £400-450. She is insured, but as dental isn't covered, even though this is actually a disease rather than a condition iyswim, I'm wondering whether there's any point even asking (insurance is Argos). Luckily we can afford it.
Any advice?
