The prevention of bottle caries is mainly to quit the habit of night feeding and avoid sleeping with a pacifier. Warm water can be added to the bottle after feeding to dissolve the sugar in the food. Parents should pay attention to help their children to clean the surface of the teeth to reduce the risk of caries. For teeth that have already developed caries, if the child is able to cooperate, relevant treatment should be carried out. In conclusion, bottle caries is mainly prevented as a treatment option because children are still relatively young, so the sense of cooperation is not enough. If available, caries treatment under general anesthesia can be taken in the hospital.
