Patients with orthodontic problems can benefit from treatment at nearly any age. An ideal time for placement of braces is between 10 and 14 years of age, while the head and mouth are still growing and teeth are more conducive to straightening. What is the right age for orthodontic treatment? Most parents know that dental care for their children should start during their early years. Experts suggest that the best age for an orthodontic assessment is 8 to 10 years; during that time period, a child usually has a combination of baby teeth and mature teeth.
