Invisalign is a tooth straightening treatment that offers a discreet alternative to traditional metal braces.

Invisalign uses transparent aligners to treat misalignment, gaps, overcrowding and mild bite issues. The aligners are made of clear plastic that are worn over the teeth to gradually move them into the desired position.

Unlike metal braces, Invisalign does not have wires and is more comfortable to wear. The aligners differ in shape so they can move the teeth into position in a step-by-step method. Patients usually change the trays every two weeks or as directed by their dentist. Most certified providers recommend wearing the Invisalign aligners for 20-22 hours a day. They should only be taken out for eating, drinking, and brushing their teeth.

The duration of treatment is usually much shorter than the traditional metal braces, taking an average of 1 year to complete. Invisalign can be used on both teenagers and adults. They are most popular among adults who have worn metal braces in the past but did not maintain their straightened teeth with a retainer. Invisalign also requires a retainer post-treatment to keep the teeth aligned. 

The process of an Invisalign treatment begins with a consultation where a dentist first takes X-rays and 3D models of the patient's mouth. They create a personalized treatment plan and determine the length of the treatment with the Invisalign technicians. Some patients with overcrowding issues may need to undergo an Interproximal Reduction (IPR) procedure. The dentist polishes down small increments of enamel to make space for teeth to move into alignment. It is normal to feel some tightness with every change of aligner set. But as the teeth move into position, the pressure subsides within a day or two. 

Patients should stick to the 2-week rule when changing their aligners to allow their teeth and gums to adjust accordingly. However, some cases can involve a change every week for faster results.

Dentists usually schedule an appointment with their patients every six weeks to check their progress. Patients need to avoid any colored food or drinks that could stain their teeth, and they should also brush and floss regularly. At the end of the treatment, patients receive a night-time retainer that helps hold their new and improved smile. Some cases may not be suitable for Invisalign treatment to get optimal results. More complex orthodontic issues may require traditional metal braces or advanced techniques.
