Most patients will notice visible improvements in their smiles within six weeks of starting Invisalign treatment. For some, the difference can be seen in as little as two weeks, while others with complex cases may take longer. Your dentist in Farmingdale, NY will examine your teeth and likely take X-rays to determine the best course of action. Aligners are designed to move a few teeth at a time in small steps.
A 3D computer generates the coatings for use in a specific order, and the number of aligners needed can range from 12 to 48 depending on the number of teeth being moved and how much they need to be shifted. Patients often ask how long retainers last, and the answer is usually between two and five years. If your retainer is still within its lifespan, you may be able to get away with using your last set of trays for a week or two to bring your teeth back into position. If that doesn't work, you'll need to contact your provider for a solution. On average, it takes 6 to 12 months for teeth to move into the correct position with Invisalign.
Each custom-made aligner moves the teeth smoothly and gradually until they are in place. Invisalign will move your teeth horizontally, vertically and even rotate them as needed. These aligners are designed to use the right amount of force in the right place at the right time, so as you change your Invisalign aligners each week, your teeth will become progressively straighter. If you had several dental problems or a moderate to complex correction, it's more likely that your teeth will return to their old crooked position if you don't use a retainer. Minor corrections can also relapse if you don't use a retainer, but it's not as likely.
To achieve optimal results, Invisalign gradually aligns the teeth which minimizes discomfort and ensures a precise and healthy smile. Usually, teeth that are crooked or out of place move last, so it can take a while to notice dramatic results. When most people think about orthodontics, they tend to consider only the time when they are actively straightening their teeth with Invisalign or braces. If you've just finished Invisalign treatment in Prior Lake, MN, there's a chance you might wonder if your teeth will move backwards after you stop using the last tray. Keep in mind that most people wear retainers for the rest of their lives because the teeth can try to return to their original state without the added pressure. The movement of the teeth after Invisalign is why an entire industry of retainers is emerging along with the rapid growth of Invisalign.
Teeth that need more rotation during treatment are usually the first to move after treatment is finished. Your orthodontist may have given you new aligners or made adjustments to increase pressure on your teeth and move them in the desired direction. By removing this orthodontic device, pressure will no longer be applied to the teeth, allowing them to move; this is natural and generally expected. However, in some cases, an orthodontic specialist may place a retainer on the teeth with dental glue. It's important to remember that when you finish Invisalign treatment, you'll need to wear a retainer for life if you want your results to last.
Without regular use of a retainer, your teeth may start shifting back into their old positions. To ensure that your smile stays straight and healthy for years to come, make sure you follow all instructions from your orthodontist regarding wearing and caring for your retainer.
