How Invisalign Braces Work – A Step By Step Guide

Clear aligners like Invisalign provide an alternative to traditional braces for teeth straightening. The process involves a series of custom-made trays that gradually shift teeth into position.

Here is a breakdown of how the invisalign braces treatment progresses from start to finish.

Initial dental consultation:

The journey often begins with a visit to a dental clinic. During this appointment, the dentist checks the condition of the teeth and gums. The goal is to see if clear aligners are a suitable method for correction. This step may involve taking photographs, X-rays, or scans to capture the exact structure of the mouth.

Digital scanning and treatment planning:

After the first visit, a digital scan or mould of the teeth is usually made. This allows for a detailed plan to be created. Using specialised software, the dentist maps out how the teeth are expected to move over time. The result is a series of aligners, each shaped slightly differently, to guide the teeth into their new position.

Receiving the first set of aligners:

Once the aligners are ready, the dentist provides the first set and explains how to wear and care for them. Aligners are typically worn for about 20 to 22 hours each day and removed only for eating, drinking, brushing, and flossing. It is normal to feel some pressure when wearing a new set, especially during the first few days.

Wearing aligners and progress checks:

The aligners are changed regularly—often every one to two weeks. Each new set is slightly adjusted to continue moving the teeth gradually. Follow-up visits are usually scheduled every few weeks to check progress. During these appointments, adjustments to the plan may be made if necessary.

Maintaining oral hygiene:

Keeping the aligners clean is part of daily care. They are rinsed and brushed gently to prevent build-up. Brushing and flossing the teeth after meals before putting the aligners back in are also encouraged to avoid trapping food and bacteria.

Final stages and retainers:

Once the teeth reach the desired position, the dentist may provide retainers to keep them in place. These are also clear and worn mostly at night. This step helps maintain the results and prevents the teeth from shifting back over time.
