0.33 mm You need to wear around 10 to 30 removable plastic aligners or more. Each aligner will shift teeth 0.33 mm before you wear the next aligner. Every tray shifts teeth and applies pressure in different regions as you increment through the trays. On average, a single aligner tray moves teeth 1/10th of mm.

Depending on the degree of misalignment, the orthodontist suggests the number of aligners. Although the teeth shift position with each set of aligners, their movement is restricted to a fraction of a millimeter during the first week. Although you would need 10 to 12 weeks before noticing a subtle difference.

Invisalign uses a series of small movements to move your teeth. The reason it can do this is that it places constant pressure on your teeth. The teeth move just a bit with every new aligner, but you may have a few dozen. Doing your part by wearing the aligners consistently is important to see results.

Sometimes Invisalign treatment starts with moving the front teeth since they're the most crooked. Other times, the answer to which teeth will move first is the back teeth, since they're the biggest teeth and might require the most time to move.

A rule of thumb is 0.5 mm of movement per tooth per aligner. It is important to understand that the maximum amount of movement allotted to any one tooth is 2.5 mm of movement and cuspid movement is about one-half of the movement we can achieve with incisors.

Typically, the lateral incisors or the teeth next to your front teeth are the most challenging to move with Invisalign aligners and traditional braces.

The goal of both traditional braces and Invisalign treatment is to move teeth into proper position over time, not overnight. While that's the case, people who choose Invisalign can sometimes expedite their results by wearing their aligners for the recommended 22 hours per day.

Wear your aligners for at least 22 hours daily Dentists recommend you keep your aligners in for around 20-22 hours each day, but 22 hours gives you the best chance of accelerating the process. Many complaints about slow-working treatment stems from patients not wearing their Invisalign for the required length of time.

They do not change face shape, nose, or jawline noticeably. It is the reason most people prefer them over traditional braces. It is essential to understand the relation between your facial features, tooth alignment, and jaw before going for orthodontic treatment.

If the aligner trays seem like they are not fitting around any of the teeth, they won't be tracking properly and you will need to alert your dentist about this. For proper tracking, the trays should feel tightly secured around all of the teeth, with no gaps.

Typically, the lateral incisors or the teeth next to your front teeth are the most challenging to move with Invisalign aligners and traditional braces.

Each tray, including the first one, is manufactured to straighten your teeth more than the previous tray slightly. Your first Invisalign tray will typically move the teeth around 1/10mm.
