A Few Months or a Few Years? How Long Does Invisalign Really Take to Work?

The Invisalign treatment has been rising in popularity in recent years as a promising alternative to metal braces for straightening or realigning your teeth. Invisalign trays are removable and virtually invisible, making them a popular option for self-conscious teenagers and adults who choose to correct teeth issues later in life.

But how long does it take for Invisalign to work? Does it take longer or less time to fix issues than braces? In this blog, we’ll outline everything you need to know about Invisalign treatment times, depending on your specific needs.

How Does Invisalign Work?

Before we get to the average length of Invisalign treatment, let’s take a second to understand how the process works.

Invisalign trays are custom-made to fit your teeth. A 3 D scan is done and plastic trays are fabricated to be worn in order. When worn, it applies gentle pressure, slowly pushing teeth into their proper positions over time.

Invisalign was approved for use over 20 years ago and is one of the most common dental treatments in the Valley Village today.

How Long Does it Take to Straighten Teeth with Invisalign?

So, how long does the Invisalign process take? The simple answer is that it depends.

In most cases, the average time for Invisalign is between 9 to 18 months, but some patients see results as quickly as a few months.

The treatment times depend on several factors, including the issues you’re attempting to fix or how compliant you are with your dentist’s instructions. Invisalign treatment times are heavy case based; what works for one patient might not work for another. Therefore, a thorough Invisalign consultation with a dental professional is necessary to make a final decision.

Mild Misalignment

Invisalign has proven to be highly effective in dealing with minor adjustments. If you’re facing minimal rotation and gaps smaller than 2 mm, the Invisalign treatment time could be as short as six months.

Moderate Misalignment

How long does Invisalign take in the case of moderate misalignment? If you have a slight overbite, a gap between 2-5 mm, or significant crowding of teeth, it may take slightly longer to fix — anywhere between 12 to 18 months.

Severe Misalignment

For major rotations or gaps bigger than 5 mm, the average Invisalign time could extend beyond 18 months. However, if this is the case, we recommend consulting a dentist near you in Studio City to determine if Invisalign is the right option for you. Gaps over 6mm, for instance, can’t be closed without metal braces or esthetic dental treatment alternatives might be considered such as veneers.

Factors That Impact Invisalign Treatment Time

Other Factors That Impact Invisalign Treatment Time

Besides the severity of the case, certain other factors could influence the average length of Invisalign treatment.

Treatment Goals


Invisalign treatment time depends on your purpose for getting a treatment done. If you’re looking for purely cosmetic benefits, the duration can be much shorter than if you’re getting the treatment to deal with a serious issue.

Compliance Levels


One of the major benefits Invisalign offers over braces is that it can be removed at any time. However, most patients don’t realize that the retainers must be worn for 20-22 hours a day for maximum effectiveness. If you slip them out multiple times a day, you can expect the average length of Invisalign treatment to increase.

Similarly, if you don’t stick to the recommended treatment time, your misalignment may worsen, increasing the average time for Invisalign treatment.

Cleanliness and Care


The one downside to Invisalign over regular braces is that they require a very specific cleanliness routine. Braces are cleaned every time you brush, but Invisalign retainers must be carefully brushed at least twice a day and soaked in a cleaning solution.

If the water you wash it in is too hot, it can ruin the integrity of the tray and lead to longer healing times.

Overall Oral Health


Meanwhile, if you don’t wash your retainers at all or fail to maintain good hygiene practices, you might develop dental cavities which in turn might create complications and lengthen the Invisalign treatment time For maximum impact, you need to follow the recommended guidelines — brush regularly and avoid foods that stain or get stuck in the retainers.

Is Invisalign More Effective Than Braces

Is Invisalign More Effective Than Braces?

Invisalign vs braces: Which takes longer? While certain conditions can only be treated with metal braces, Invisalign has shown signs of being more effective over shorter periods of time. The treatment can resolve mild to moderate misalignments in 9 to 18 months, while braces can take up to two to three years.

Does Age Impact Average Length of Invisalign Treatment?

There is no overwhelming evidence to suggest that age affects the average time for Invisalign treatment. The average length of treatment heavily depends on multiple factors such as initial tooth position and final desired position, bone density of the jaw, and etc. Age should not be a limiting factor when you are looking for a dentist near you for Invisalign treatment.
