Advantages and disadvantages of the finger probe technique in neonatal craniofacial development

Abstract

Introduction: Craniofacial development in the neonatal stage depends on early functional stimuli, especially those related to food. The establishment of sucking, swallowing and breathing patterns is key to the maturation of the stomatognathic system, made up of bone, muscular and neurosensory structures. The finger probe feeding technique is used in newborns with suction difficulties, seeking to preserve the sucking reflex, favor oral neuromuscular maturation and maintain orofacial functionality without resorting to the bottle. Objective: To analyze the scientific evidence available between 2020 and 2025 on the advantages and disadvantages of the facial growth finger probe technique in newborns from the dental approach. Review: Available studies describe benefits in sucking-swallowing-breathing coordination, weight gain and faster transition to oral feeding. However, there is no evidence to evaluate its direct impact on craniofacial growth. Research focuses on clinical and nutritional variables, without integrating parameters from dentistry. Conclusions: The technique shows positive effects on oral function, but the evidence about its direct influence on facial growth is limited or non-existent. Recommendations: Interdisciplinary research is required that incorporates dental criteria to evaluate its effect on neonatal facial growth.
