Abstract
We observed tooth losses (and subsequent alveolar resorptions) and other cases of anodonty and polydonty and anomalies in the shape and occlusion of the teeth in skulls of wolves from the former Soviet Union. Resorptions increase in number with age, but do not seem to have much of an effect on individual survival (they probably do not affect hunting), and are found in half of individuals over 8 years of age. The highest numbers of resorptions, as well as cases of polydonty and dental anomalies, were in the premolars. This suggests that the premolars are not greatly subject to selective pressure. At least 6.8 % of the skulls have malformed teeth or malocclusions.
