One of the most common questions my patients ask me is: “How long will Invisalign take to straighten my teeth?” The honest answer is that it depends on your unique case.

On average, Invisalign treatment takes between 6 to 18 months. Many patients start noticing small improvements within just a few weeks, which is exciting and motivating. However, the total treatment time varies based on how complex your smile needs are.

Quick cases vs. complex treatments

If we’re simply aligning mildly crooked front teeth, treatment can be surprisingly quick — sometimes just a few months. On the other hand, if we’re correcting a bite issue such as an overbite, underbite, or crossbite, the process usually takes longer. This is because we’re not just moving teeth but also guiding how the upper and lower jaws fit together for a healthier, long-term result.

Adults vs. children

Another factor that influences treatment length is age. With adults, Invisalign usually focuses on aligning teeth and improving the bite within the limits of a fully developed jaw. Children and teenagers, however, may have Invisalign as part of a wider orthodontic plan. Because their jaws are still growing, we can sometimes use this to our advantage, staging treatment over a longer period for a more comprehensive outcome.

Tailored treatment plans

The beauty of Invisalign is that it’s completely customised. At your consultation, we use advanced 3D digital scans to map out every step of your tooth movement. This technology allows me to give you a clear idea of how long your treatment is likely to take, before you even begin.

Whether your Invisalign journey lasts a few months or over a year, the goal remains the same: to achieve a healthy bite and a confident smile that lasts a lifetime.

If you’re considering Invisalign and want to know how long your treatment might take, the best next step is to book a consultation. Together, we’ll create a plan designed around your smile goals, lifestyle, and dental health.
