The effects of breastfeeding on the occlusion have been much debated, and it is often suggested that breastfeeding facilitates optimal development of the jaws and the dentition, thus preventing the development of a malocclusion. Despite these claims, the evidence is equivocal, and the majority of studies are of low quality and only assess the deciduous dentition. Therefore, at present there is currently no high quality evidence to support claims that breastfeeding has a positive effect on the occlusion, thus the method of feeding should be chosen due to the health benefits and personal preference, not due to any claims regarding occlusal benefits that cannot be substantiated.
