Invisalign is a globally recognised clear aligner system that has proven to be effective in correcting a wide range of teeth alignment issues, from mild spacing to more complex cases. Often referred to as invisible braces, Invisalign uses a series of custom-made aligners to gently and gradually move teeth into better alignment.
The aligners are virtually invisible, soft, and comfortable, making them a discreet alternative to traditional braces. Because they are removable, Invisalign allows you to continue enjoying your favourite foods and maintain your usual oral hygiene routine with ease.
Invisalign aligners are made from clear, medical-grade plastic, making them very discreet compared to metal braces. Most people won’t even notice you’re wearing them, which is a big plus for adults and teens who prefer a more natural look during treatment.


Unlike braces, clear aligners can be taken out when you eat, drink, brush, or floss. This means no food restrictions (yes, you can still enjoy popcorn and crunchy snacks!) and much easier oral hygiene, helping you maintain healthy teeth and gums throughout your treatment.


Invisalign typically requires fewer in-person appointments than traditional braces. Some clinics even offer remote dental monitoring, so your dentist can track your progress through photos or apps.
A straighter smile can make a huge difference in how you feel. With Invisalign’s discreet design, many patients feel more confident throughout their whole journey and more so after treatment.
Invisalign can correct a wide range of teeth alignment problems (known as malocclusions) including overcrowding, overjet, underbite, crossbite, open bite, and spacing.

Overcrowding is when there is insufficient room in your jaw for your teeth to fit normally. Your teeth can bunch up, overlap, twist, or get pushed to the front or back.
An excessive overjet, also known as buck teeth, is when your upper front teeth extend too far horizontally over your lower front teeth. This is not to be confused with an overbite, which is a vertical overlap of the lower teeth by the upper.
An underbite is when your lower teeth and jaw protrude in front of the upper teeth. Severe cases may cause difficulty chewing food or challenges when speaking.
A crossbite is when some of your upper teeth sit behind your lower teeth. This may lead to abnormal tooth wear and chipping.
An open bite is when your upper and lower teeth do not touch when your mouth is closed. This may affect your appearance and cause speech problems like having a lisp.
Spacing is when there is a gap between two or more of your teeth. It may cause speech problems and food can get stuck easily.
From consultation to completion, the Invisalign process is closely supervised by a licensed dentist. These dentists possess the orthodontic knowledge to recommend suitable treatment options for specific cases and tooth movements.
They will ensure you are well-informed about your treatment options, instruct you on proper aligner use, and address any concerns you have along the way.
With SmartForce® attachments, tooth movements such as rotation, extrusions, and translations are now feasible! These barely noticeable, tiny tooth-coloured shapes are attached to your teeth and work alongside your aligners, guiding your teeth precisely to their desired positions.
Your Invisalign aligners are crafted from SmartTrack®, a medical-grade polymer. Align Technology developed this material over 8 years, testing 260 different materials to ensure optimal quality.
With this material, your aligners will fit snugly and move your teeth with gentle, consistent pressure, maximising comfort throughout your treatment.

Retainers are crucial in helping you maintain your smile after treatment is complete. You may need to replace them periodically as they are likely to experience wear and tear over time. Below are the different types of retainers available at i.Dental, along with their respective prices (inclusive of GST):
In 2014, i.Dental was appointed as an Invisalign Dedicated Clinic in Singapore by Align Technology. This designation reflects our long-standing focus and experience with Invisalign treatments. Over the years, our team has continued to refine our approach, staying up to date with the latest Invisalign techniques and advancements to ensure patients receive well-planned and reliable care.
We use digital dentistry to make Invisalign treatment more accurate and comfortable. This includes 3D teeth modelling with the iTero Intraoral Scanner instead of traditional moulds, digital X-ray with lower radiation, and Dental Monitoring to track aligner fit and treatment progress for timely adjustments.
We believe good Invisalign results come from more than just aligners. From your initial consultation to your final check, our team takes the time to explain each step, track your progress, and support you throughout your treatment.
With multiple i.Dental clinics across Singapore, fitting Invisalign appointments into your schedule is easy. Whether it’s reviews, refinements, or follow-ups, you can choose a location that works best for you.
We offer different Invisalign treatment plans designed to suit varying levels of teeth alignment needs, age groups, and treatment goals. From minor cosmetic adjustments to more complex bite corrections, each Invisalign plan differs in treatment duration, number of aligners, and overall scope. Your dentist will recommend the most suitable option based on your dental condition and desired outcome.

Ideal for very minor corrections, Invisalign Express is designed for small movements such as slight crowding or spacing. Treatment is typically short and best suited for patients seeking quick cosmetic improvements.
Complexity of Condition: For relapse cases and very minor movements
Aligners Included: Up to 7 sets
Treatment Duration: 3 – 6 months
Invisalign Lite is suitable for mild to moderate alignment issues. It offers more flexibility than Express and is often chosen by patients who need noticeable improvements without undergoing full comprehensive treatment.
Complexity of Condition: Ideal for mild crowding and spacing, no extractions required
Aligners Included: Up to 14 sets
Treatment Duration: 6 – 12 months
This plan addresses moderate orthodontic concerns such as more pronounced crowding or spacing. Invisalign Moderate provides a greater number of aligners and a longer treatment window for more controlled tooth movement.
Complexity of Condition: Meant for less complex crowding or spacing cases
Aligners Included: Up to 26 sets
Treatment Duration: 1 – 2 years
Invisalign Comprehensive is the most extensive plan and is designed for complex cases, including significant misalignment and bite issues. It allows for unlimited aligners and refinements throughout the treatment period to achieve optimal results.
Complexity of Condition: Suitable for complex cases like crowding and spacing.
Aligners Included: As many as needed
Treatment Duration: 2 – 3 years
Invisalign First is designed specifically for children, typically between the ages of 6 and 10, who are still in their early developmental stages. This phase focuses on guiding jaw growth, correcting early bite issues, and creating space for incoming adult teeth. By addressing problems early, Invisalign First can help reduce the need for more complex orthodontic treatment later on.
The aligners are made with smaller mouths in mind and are gentle enough to accommodate growing teeth. Invisalign First may also includes compliance indicators — small blue markers on the aligners that fade over time when worn correctly. This helps parents and dentists easily track whether the aligners are being worn for the recommended number of hours each day, ensuring treatment stays on course.
Complexity of Condition: Designed for growing children with developing jaws and mixed dentition
Aligners Included: Varies depending on child’s growth and needs
Treatment Duration: 12 – 24 months
Invisalign Teen is tailored for adolescents whose permanent teeth have mostly erupted and who require more active orthodontic correction. It can treat a wide range of issues, including crowding, spacing, overbites, underbites, and crossbites, all while fitting seamlessly into a teenager’s daily routine.
Like Invisalign First, Invisalign Teen aligners may also feature compliance indicators to help monitor wear time. This is especially helpful for busy teens juggling school, sports, and social activities. In addition, Invisalign Teen often includes replacement aligners at no extra cost, offering peace of mind in case aligners are lost or damaged.
Complexity of Condition: Suitable for teenagers with developing teeth, including eruption of new teeth
Aligners Included: Varies; includes features like eruption tabs & compliance indicators
Treatment Duration: 12 – 24 months
ClinCheck® is used by our dentists to develop a customised digital treatment plan, detailing your teeth’s precise movements. Your Invisalign aligners are designed to exert the correct force at the right locations and times, with our dentist overseeing your progress and fit throughout the treatment.
You may feel some pressure or tightness when you start a new set of aligners, especially in the first few days. This is completely normal and usually means the aligners are working as intended. Most patients find Invisalign far more comfortable than traditional braces, and any discomfort typically fades quickly.
Invisalign is suitable for adults, teenagers, and even children with developing teeth. There are different Invisalign options designed for each age group, and suitability will depend on dental development and individual needs.
Invisalign can treat a wide range of cases, including more complex alignment and bite issues. A proper assessment is required to determine suitability, and in many cases, Invisalign can be a viable option with the right treatment planning.
Invisalign is a type of orthodontic braces that is clear and removable. On the other hand, braces are fixed onto your teeth and are easily visible. Other differences between Invisalign and braces include:
Not necessarily. Many Invisalign cases can be treated without extractions, especially mild to moderate crowding. However, if space is limited or the case is more complex, extractions may be recommended. But this will be assessed by your dentist during your consultation.
This depends on the condition of your teeth and the treatment plan your dentist has in mind. For example, wisdom tooth removal is recommended if you have an impacted wisdom tooth.
On the other hand, removal may not be required if your teeth have erupted well and are properly positioned. The wisdom teeth may be kept as an anchor to help align other teeth during the treatment process.
Treatment duration can vary significantly depending on your condition and desired results.
A typical treatment can take about 1.5 to 2 years but there are orthodontic devices available from our clinic that you can use to speed up your treatment. Devices like Acceledent and VPRO5 are able to cut treatment time by as much as 30%-50%.
It is recommended for you to wear it at least 22 hours per day.
Almost immediately! Invisalign is designed to fit into your daily life, so you can continue working, exercising, playing sports, and even musical instruments as usual.
Rinse your aligners regularly with water and clean them gently using a soft toothbrush. Avoid hot water, as it can warp the aligners.
Most people change to a new set of aligners every 1 to 2 weeks, depending on their dentist’s instructions.
Consistency is key! Wearing your aligners for the recommended 20–22 hours a day helps each set do its job properly. Your dentist will track your progress during reviews and may adjust the schedule if your teeth need more time or are moving faster than expected.
Appointments are usually spaced out every few weeks to monitor progress and ensure everything is on track. With tools like digital monitoring, some reviews can be less frequent compared to traditional braces.
Our dentists will recommend the different types of retainers which you can wear. You will also be advised on the daily duration of wearing your retainers. This is to prevent your teeth from gradually shifting back to their initial position.
After treatment, retainers are essential to keep your teeth in their new position. There are different types of retainers available, and your dentist will recommend the most suitable option based on your needs. Retainers may need to be replaced over time due to normal wear and tear.
Invisalign Attachments are small dots that are stuck to your teeth at specific locations.
After IPR is done (if required), attachments may be used to provide grip for your Invisalign aligners to apply pressure to your teeth to guide them to their desired locations.
