How does Invisalign work?

Invisalign uses clear aligners created specifically for your own mouth to gradually and gently move your teeth into place. Every couple of weeks a new, specially modified aligner is worn, moving the teeth little by little until they have straightened into the prescribed position determined by your dentist.

Like traditional braces, Invisalign works by exerting consistent pressure on your teeth to move them slowly into place. Because the aligners change every few weeks, your dentist can target different areas over the time of your treatment.

Depending on your individual treatment plan, you may use as little as seven aligners, or as many as forty. Your dentist will use X-rays, pictures, and impressions to create a precise 3-D image of your teeth and to configure your aligner trays accordingly.

Invisalign aligners are made of strong, medical grade thermoplastic material, which is, importantly, BPA free.

How long does treatment take with Invisalign?

Obviously, everybody’s teeth are different, and so the time frame for treatment varies according to the corrections that need to take place. In your initial consultation, your dentist will tell you the likely length of treatment, and how many individual aligners you will need. Treatment can vary between 6 months and 2 years, with the average length of treatment being about a year. In some cases, your teeth may take longer than predicted to align fully. In these instances there may be some additional ‘refinement’ aligners. If needed, these do not cost extra but can add some time to the overall treatment.

Once treatment has concluded, as with most braces systems, a temporary retainer will need to be worn for some time after to stabilise teeth in their new positions. This will be custom made for you once your teeth are aligned.

Does Invisalign treatment hurt?

Invisalign is one of the most comfortable orthodontic options available. The aligners are smooth with no sharp or protruding edges, so they won’t graze or rub in your mouth. While there may be some discomfort with each new aligner, this will fade within a few days. This is simply the result of the pressure of the aligner moving your teeth.

Is Invisalign right for me?

Comparing Invisalign® vs braces

Both Invisalign® and braces have the same goal - to straighten and align your teeth for better oral health and a more confident smile. However, they achieve this in different ways.

With braces, your orthodontist will attach semi-permanent brackets to each tooth, which will be attached by a wire that works to slowly move your teeth into place. You will wear these braces until treatment is complete, which is usually 12-24 months. These braces are obvious whenever you open your mouth to eat or speak.

With Invisalign®, you will wear a series of clear trays custom-made for your mouth that will slowly move your teeth into place. You can take the trays out when you eat and drink, or for special occasion photos. It takes about the same amount of time as braces, but Invisalign® is not immediately obvious when you open your mouth - someone would have to be quite close to see the tray.

The right option for you will depend on your specific needs and circumstances. Invisalign® is typically more expensive, but the extra cost may be worth it if you would prefer a more discreet treatment.
