Orthodontics is an area in dentistry which involves correcting the jaw and teeth alignment. There are many cause of “crooked” teeth and this could be from thumb-sucking, hereditary conditions, limited space or from a trauma. There are different ages for orthodontic and orthopaedic interventions. It is recommended that your child has a brief orthodontic assessment before the age of 4 and again at age of 7 to see if there are issues that can be addressed early. Typically children between the ages of 10 and 14 are at a stage where their faces are growing and treatment with braces and functional appliances are effective. Prompt referral by your dentist can be arranged for a consult with an orthodontist.
If you are an adult and would like your teeth better aligned this can still be done. Your face would have stopped growing, but it is still possible to move teeth.
