Invisalign vs Braces: Which Works Faster and Why If you want to fix your smile fast, Invisalign could be the quicker choice for mild gaps or small crowding, sometimes taking just 6 to 8 months. But for more serious cases, both Invisalign and braces can take up to two years or more. The right choice depends on your case. Braces work continuously, while Invisalign depends on how disciplined you are in wearing them. Come and book your appointment with T Care Dental today. Our dentists will help you
