When a veterinary surgeon performs an equine dental examination the teeth and skull are examined for any over growth and abnormalities. The overall aim is to provide a grinding surface that the horse can effectively use to perform the first stage of the digestion process. Effective chewing or ‘mastication’ is very important as the high fibre and cellulose feeds horses eat require considerable breakdown and mixing with saliva before it enters the stomach. If the horse is unable to do this effectively then it will not be able to utilise the nutrients and calories of the feed. In extreme cases the mouth may be so distorted that the horse will not be able to chew at all, this often is noticed when the horse begins to loose weight and drop feed (quidding).
