Our cosmetic dentist in Billerica, MA, plans for your treatment based on personalized needs. Additionally, the duration of your treatment will vary based on the condition of your dental misalignment. Your specialist will determine the time of your treatment based on your progress. You can wear clear aligners for 12 to 18 months, and the longer you wear Invisalign aligners, the better the outcomes. Before your treatment is over, you’ll notice that your teeth are straightening with time.
