Not sure about fang-farrier insurance. Most people reckon that the cover isn't worth it as you may as well pay for treatment if/when you need it. Plus, unlike medical insurance which can be compared to breakdown cover being insured after you've produced evidence of having a current MoT, dental insurance seems to be more like "Yes, OK. If you fit 4 new tyres, have the engine overhauled and that dent in the door repaired first, then we'll cover you....." Unless someone can correct me?
