What is the Invisalign system?

It is an orthodontic treatment well-known for its clear aligners which are made from BPA-free plastic. These aligners are used to gradually move and straighten your teeth to desired position without causing too much interruption in your lifestyle.

Why Invisalign?

Helps to properly align teeth (crooked, gaps, crowded or overlapping) which helps to correct improper bites, any chewing difficulties or jaw issues. For some patients, it may even help with their speech and ease doing oral hygiene care.

The advantages of Invisalign treatment

Invisalign aligners are removable, making it easier to brush and floss to maintain your oral health during treatment.

Attend functions and events in confidence with Invisalign aligners. Virtually invisible, very few people would notice you’re having your teeth straightened.

Get straighter teeth more comfortably thanks to innovative SmartForce and SmartTrack technologies in Invisalign aligners.

Invisalign aligners are suitable even for an active lifestyle since there are no metal brackets cutting your mouth.

With doctor visits only approximately every 3-5 weeks, Invisalign aligners are ideal even for a busy lifestyle, allowing you to spend more time doing the things that you love.

Craving a snack? Since Invisalign aligners are easily removable, you have the freedom to eat, chew and drink whatever you like.

How does the Invisalign system work?


Using Align Technology’s proprietary

software, your doctor will create a customised 3D treatment plan. This will show you the final position your teeth are predicted to reach. This also informs you of the likely length of the treatment.

The customised aligners

will be manufactured and shipped to your doctor’s office.

Your series of custom-made aligners

will be given to you (typically 3-4 sets at a time) for you to wear every day, and change approximately every 1-2 weeks.

You will visit your Invisalign trained doctor

approximately every 3-5 weeks to monitor your progress, and receive the next series of aligners.


You have finished your Invisalign treatment! Maintain your newer, better smile with the use of retainers.

About Consultation

Unfortunately, Invisalign is not suitable for all orthodontic cases hence, we offer a consultation with our experienced dentists to do the assessment and discuss the treatment options available for you.

Treatable Cases

Invisalign clear aligners are clinically proven to treat cases from minor teeth straightening to moderate and severe malocclusions.

Gapped Teeth

This occurs when there is considerable space between at least two of your teeth, and can cause gum problems.


This can occur when the upper and lower jaws are both misaligned, and can cause wear and tear leading to bone loss.


This occurs when the upper teeth bite over the lower teeth, and can lead to painful jaw irritation.


This occurs when the lower teeth protrude past the front teeth, preventing normal function of your front teeth or molars.


This occurs when there is simply a lack of room within your jaw for all your teeth to fit normally, leading to plaque accumulation.


This is when your upper and lower teeth are unable to make physical contact when the jaws are closed, making chewing and even talking difficult.

About Procedure

In Niddrie Dental Clinic, we use the latest technology, the iTero scanner to create a digital scan of your teeth so you can peek at what your smile could look like with straighter teeth on the spot!

The dentist will discuss your treatment plan and give you a review of how it will progress. When you’re happy with the treatment plan, all we have to do is wait for the aligners to arrive and start the Invisalign.

Generally, the treatment would go for a few weeks to a few months depending upon how much crowding you have or how much your teeth need to move as well as on various factors. The dentist will inform you while discussing your treatment plan.

Frequently Asked Questions

Is Invisalign treatment painful?

This treatment involves moving your teeth gradually by applying gentle and constant pressure. Some people do feel discomfort for the first few days of wearing the aligners. They usually describe it as ‘pressure’ more than pain. However, if you do feel extreme discomfort or have had pain for many days, please call the clinic.

Do I need to wear it while I’m sleeping?

You need to wear your aligners at least 20-22 hours a day to get optimal results. It is very unlikely that your aligners would fall out, so you can have it on while sleeping, talking, and even laughing.

Will smoking stain my aligners?

Yes, it can stain the aligners hence, we recommend no smoking or minimal if possible.

Are there any restrictions on diet?

Nope! As the aligners are removable, it is convenient to eat what you want.

However, do note that you are advised to avoid having hot and sugary drinks. You are advised to avoid biting anything hard on the front teeth.

Can I take off my aligners when I need to?

Yes, you are advised to remove them when eating, drinking, or doing your oral hygiene. Even for special occasions like interviews, wedding functions, or graduations.

Do note if you took it off for a certain period for such functions, you will be advised to wear them for those hours afterward.

Since having my braces removed, my teeth have shifted. Can Invisalign fix this?

Yes, as Invisalign helps with straightening teeth, you can do Invisalign even if you’ve done braces before. Many people prefer Invisalign as it is more discreet.

I have veneers or crowns done. Can I still do Invisalign?

Depends. We would highly recommend a consultation with our dentist to assess and evaluate the situation.

How do I clean my aligners?

Brush and rinse them in lukewarm water. Always remember to brush your teeth after each meal before popping back the aligners.

What if I lose or break an aligner?

Call the clinic and inform the dentist about the situation. He or she will ensure you stay on track with your treatment plan which may involve wearing a previous set of aligners or the next one or even ordering replacement ones.

How long will I need to wear the retainers for?

Our dentist recommends wearing the retainer to prevent the teeth from shifting back or moving in a different direction which changes the smile. Every case is different, so you will need to ask the dentist.
