I would say that there's probably no age that's too young. Even braces or orthodontics are considered cosmetic treatments, so sometimes we begin to consider orthodontics or orthodontic appliances quite early. Many parents often ask when it's appropriate to start thinking about cosmetic treatments for their child, and the truth is there isn't really an age that's too young. This is because we can often intervene, even when children still have baby teeth, to help align their permanent teeth better. This, in itself, is a form of cosmetic improvement. Additionally, on the orthodontic side of things, we can sometimes use appliances, not necessarily full braces, to help align teeth as the permanent ones start coming in.
When it comes to more advanced cosmetic procedures like veneers or replacing a missing tooth with an implant, we typically start considering those a bit later, often in the late teenage years. This timing is usually determined by the child's development. The best course of action can be assessed by visiting your dentist or coming to see us, and we can evaluate your child to provide you with the most suitable guidance.
