Invisalign

Invisalign clear aligners in Singapore

A clear, removable way to straighten teeth, with treatment options for children, teens and adults.

Invisalign works through a planned sequence of aligners, each one moving your teeth a small amount, until they reach the position your dentist has designed. Because the aligners are removable, you take them out to eat, brush and floss, which makes cleaning easy and means there are no food restrictions.

Not every case is suited to clear aligners, and we will tell you honestly if fixed braces would do a better job for your situation. Where Invisalign is a good fit, it is a discreet, comfortable option that fits around work, school and life.

The Invisalign treatment options

Invisalign treatment is tailored to how much movement your teeth need. The main options differ in how long they take and how many aligners are involved.

Invisalign Full

For complex or severe orthodontic corrections that require significant tooth movement, such as cases where extractions are needed to make room for alignment. Treatment usually takes 18 to 36 months, with around 36 aligners on average.

Invisalign Moderate

For moderate crowding and spacing issues. It is also a common treatment after the first phase of Invisalign treatment for children and teens. Treatment usually takes 12 to 24 months, with around 26 aligners on average.

Invisalign Lite

For mild misalignment that does not need extractions. Treatment usually takes 3 to 12 months, with 10 to 14 aligners on average.

The Invisalign process

What to expect, step by step

  1. Digital 3D scans and x-rays

Questions & answers

Invisalign: common questions

How long does Invisalign treatment take?
Most adult cases take somewhere between a few months and about a year or more, and simpler cases can be quicker, while complex ones take longer. The single biggest factor you control is wear time: aligners need to be worn around 20 to 22 hours a day, only coming out to eat, drink anything other than water, brush and floss. At your consultation we will give you a realistic estimate for your case and an idea of how often you will change aligners and come in for reviews. Treatment that includes growth, like Invisalign First or a palatal expander, follows its own timeline.
Does Invisalign hurt?
Most people describe Invisalign as feeling tight or under pressure for the first day or two after switching to a new aligner, rather than painful, and that settles as the teeth move. Because there are no brackets or wires, there is much less of the rubbing and ulcers that can come with fixed braces. If a new aligner is uncomfortable, switching to it in the evening so you sleep through the first hours can help, and over-the-counter pain relief is fine if you need it. Tell us at your reviews if anything is bothering you and we will check the fit.
Is my child too young for Invisalign?
Not necessarily. Invisalign First is designed for children who still have a mix of baby and adult teeth, roughly ages 6 to 11, and it can guide jaw width and tooth position during a window when growth makes treatment easier. For some children, an airway-focused approach with the Invisalign Palatal Expander is more appropriate, especially where the upper jaw is narrow or there are signs of mouth breathing or disrupted sleep. The right time to start depends on your child's growth and bite, so the best step is an assessment so we can advise specifically.
Will I need to wear a retainer afterwards?
Yes. Teeth naturally tend to drift back over time, so wearing retainers after Invisalign is essential to keep your result, usually full-time at first and then nightly long term. We will provide retainers and clear instructions on how to wear and look after them, and we follow up to make sure everything is holding. Looking after your retainers, and replacing them if they wear out or are lost, is the simplest way to protect the investment you have made. See our retainer wear and care guide for the details.
