While it makes sense that children with protruding front teeth might have an increase chance of having them knocked out, a study confirmed this assertion. An Australian study found that children up to age 6 with protruding teeth of over 3 mm, had triple the risk of having one or more of their teeth broken or knocked out. They also discovered that children older than 6, with teeth protruding 5 mm or more had twice the risk of trauma.
Lost or broken teeth poses future dental complications including tooth loss, the need for root canals and other procedures later in life, such as implants to replace the lost teeth. Even teeth that weren’t lost, but suffered trauma may cause further problems during Orthodontic treatment.
