In dogs, hypoplasia may occur following a [[Canine Distemper Virus]] (CDV) infection during tooth development. This is a very severe systemic disease seen early in life or in utero in dogs.
In dogs, hypoplasia may occur following a [[Canine Distemper Virus]] (CDV) infection during tooth development. This is a very severe systemic disease seen early in life or in utero in dogs.
Hypoplasia may also occur in single teeth following damage to the permanent tooth germ, for example if a deciduous tooth is fractured or extracted without care. The damaged ameloblasts will fail to form enamel and abnormalities will be evident.

In ruminants, one will see a chalky mottling and yellow brown pitting of the [[:Category:Teeth - Anatomy & Physiology|tooth]], due to enamel hypoplasia. There is usually no difficulty in mastication detected and the animal is clinically well.

In dogs, CDV causing enamel hypoplasia, may result in severe discoloration or pitting of teeth due to effect on [[Enamel Organ#Enamel|enamel]] formation.

There is no treatment for this condition. Control measures are prevention of the causes of the disease, e.g. vaccination against CDV and prevention of fluoride poisoning in cattle.

If only a single tooth is affected, restorative treatment can be performed using dental composites or a metal-alloy jacket crown.
