Because no two teeth are alike, the treatment period will vary from patient to patient. Also, the duration of your treatment will be determined by many factors, including the severity of the condition, any bite problems such as crossbite or overbite, your age, and the health of your teeth. Depending on individual needs, your doctor will determine how long your treatment plan will take. In general, orthodontic treatments such as Invisalign may take twelve to eighteen months on average. However, you can see benefits in as little as a few weeks. Braces typically take about twenty-four months to complete. Some patients require treatment in less than a year, while others need treatment for up to three years or more before their teeth reach the optimal position.
