We take particular care to ensure that brackets are stuck to the teeth in the best possible way. There are many reasons why brackets may fall off from moisture exposure (saliva) during placement of the bracket, weak enamel structure and factors related to how and what patients eat. It is interesting that a small number of patients represent the vast majority of breakages but using a stronger glue will result is significant difficulty when the braces are removed and possible damage to the tooth. This is why we stress that care is needed through the course of treatment. Often brackets fail in the initial stages of treatment when the wires are very light and weak and patients are getting used to changes in function when chewing with braces.
