Purpose: to describe the type of breastfeeding, the age at which food was introduced, installation characteristics of oral habits and the occurrence of malocclusion in children aged three to five years old. Materials and methods: Cross-sectional study with 93 children by means of a questionnaire applied to parents on breastfeeding, introduction of oral habits and food. A dental clinical examination was performed to evaluate dental occlusion. Data were analyzed by Chi-Square test and Fisher’s exact test (p<0.05). Results: 93.5% of the children were breastfed, of these, 6.4% were breastfed exclusively for more than 6 months. The median age of introduction of water and tea was five months. The use of the bottle was observed in 86% of the children and the use of the pacifier, in 49.5%. The association between exclusive breastfeeding time and the presence of oral habits was significant (p=0.035). Children with a habit of keeping their mouths open at night showed a higher frequency of onychophagia (p=0.043). The malocclusions were present in 46.2% of the children, and of these, 22.6% presented an anterior open bite. A significant association between occlusal changes and the habit of keeping the mouth open at night (p=0.034) was observed. Conclusion: Exclusive breastfeeding was a protective factor for the establishment of oral habits in the sample evaluated. The introduction of food occurred early. Among oral habits, the habit of keeping the mouth open at night indicated association with occlusal changes
