Comparing Clear Aligners in Singapore

Zenyum vs Invisalign vs Smile Direct Club vs WonderSmile

If you’re planning on getting clear aligners any time soon, then you must be looking at multiple options, trying to figure out which one will work best for you. If so, we can help.

For today, we’ve looked at a few popular companies in Singapore that offer said treatment—Zenyum, Invisalign, Smile Direct Club, and WonderSmile. We’ve compared and contrasted their services, prices, and treatment plans just for you.

We understand that costs are often one of the primary concerns, though. So without further ado, let’s talk about that first.

How Much Do Clear Aligners Cost in Singapore?

Clear aligners are certainly more affordable than traditional braces, but it doesn’t mean that they’re cheap.

In the table below, we’ve laid out their corresponding costs and available installment plans so you can plan your budget accordingly.

CompanyPrice RangeInstallment Plans
Zenyum$2,400 – $3,900
*Depending on your case complexity
3 Monthly Interest-free Payments (ZenyumClear); or Deposit of $800, Followed by 5 Monthly Interest-Free Payments (ZenyumClear Plus) 
Invisalign$4,200 – $9,000Varies per Partner Clinic
Smile Direct Club$2,500Initial Deposit of $350 + $115 a Month for 24 Monthly Payments
Wondersmile$2,490 – $2,560Initial Deposit of $498 + 3 Repayments of $664.33/Month, Inclusive of Admin Fee (All-day Aligners); or Initial Deposit of $512 +
3 Repayments of $683.33/Month, Inclusive of Admin Fee (Nighttime Aligners)

Similarly, we’ve also noted possible additional costs that you can expect to pay for your treatment apart from the actual clear aligners.

Take note that your orthodontist may require other dental treatments such as dental fillings, extractions, and cleanings. Be sure to check with your orthodontist for actual costs.

The Battle of Clear Aligners: How Do They Differ?

Now, here comes the tricky part—how exactly can you tell which set of clear aligners works best for you?

While we can’t exactly tell you which one to go for, we’ve gathered the most common questions that customers have about them in the charts below. By answering them, you can make an informed decision prior to setting an appointment.

To start with, one of the perks of getting clear aligners is that orthodontic visits are considerably less frequent. Depending on your provider’s instructions and treatment time, you may get a new set of clear aligners every few weeks or so.

And to make sure that you can easily access your chosen provider’s services, we made sure to list them down in the table below. We’ve also included the average treatment time for each brand, but take note that this will vary on a case-to-case basis.

CompanyWhere to Find ThemAverage Treatment TimeRequired Wear Time per Day
ZenyumSelect Partner Clinics3 – 15 Months
*Depending on your case complexity

The Best Clear Aligners in Singapore

To give you a better idea of what they can offer, let’s head over to our list of the best clear aligners in Singapore!

1.   Zenyum

HOW TO BEGINStart your free pre-assessment here

To kick things off, we’re starting with Zenyum—a relatively new, homegrown brand that promises straighter teeth for a fraction of the cost of traditional braces. Currently, they have 2 treatment plans available, which are designed to treat mild, moderate, and complex cases.

Unsure whether you have a mild or complex orthodontic case? We’ve outlined the process of getting a consultation with Zenyum so they can take a closer look at your teeth.

How Do Initial Consultations Work?

They work with a network of local orthodontists in Singapore who can take a closer look at your teeth and come up with a personalised treatment plan for you.

While we can see how convenient it is to have partner clinics all over the island, the lack of readily available information on these clinics may be a drawback for some. Not to worry though, as you can learn more about them pretty easily.

To see if you’re a suitable candidate for their clear aligners, you can begin by filling out their free online pre-assessment form. From there, their in-house orthodontist will review your information to determine if you’re eligible for treatment or not.

And if you’re eligible, a member of their customer service team will reach out to help you book your clinic appointment. From there, expect to get your X-rays and 3D scans so Zenyum can make the perfect set of clear aligners for your treatment.

Take note that these procedures come with separate costs, which range from $150 to $175 to be paid directly to the clinic.

Another downside to Zenyum is that their treatments are not suitable for patients below 18 years old, unless they have received a referral from their partner clinics. You can contact Zenyum to find out more about which clinic to go to.

What Happens after My Consultation?

After your orthodontist gives you the go signal, you can expect to receive your Zenyum clear aligners within 4 weeks. Moving forward, patients are entitled to a mix of in-person check-ups and in-app monitoring.

This allows you the ease of having your progress monitored remotely, as well as the assurance of in-person check-ups that everything is in order.

Depending on how your treatment goes, note that you may have to get refinements, in which case you’ll need a rescan that costs about $100. You might also need retainers to ensure that your teeth stay in the right position, which costs about $300.


  • Installment plans available
  • Several partner clinics available
  • In-app and in-person monitoring
  • Relatively affordable
  • Free pre-assessment
  • In-person fitting session
  • X-rays and full oral examination

Customer Reviews

Check out what customers had to say about Zenyum:

“Currently on my last set of Zenyum and been in this journey for almost 4 months. The team at Zenyum, especially Fizah has been making the process so smooth and convenient. For someone who was on braces before, Zenyum aligners are more affordable than other brands. This has been one of my best experiences as a customer ever!” —Ying Ying Tan, Google Reviews

“Being in my 50s, I thought the concept of having straight teeth was past me. Then a friend recommended Zenyum, and after just a few short months, my teeth are straighter than it’s ever been. I couldn’t be happier with the results. My customer care consultant, Kristofer, was a great help with my queries. I would definitely recommend this to anyone who wants straighter teeth, without the painful experience of braces.” —Colin Santa Maria, Google Reviews

Over the years, Invisalign has become a household name when it comes to clear aligners—and for good reason. They’re the pioneers of the world’s first removable clear aligner treatment, making them one of the most advanced and reliable brands out there.

Invisalign treatment can correct various orthodontic problems including overbites, overcrowding, gaps, and more.  Luckily in Singapore, there are plenty of ways to get this treatment, and here’s how.

How Do Initial Consultations Work?

If you’re just beginning your research, the most convenient option to know whether you’re eligible for treatment or not is to fill out their online form.

After a day or two, expect a representative from their team to walk you through the results and help you make an appointment as necessary. But if you’re set on the idea of proceeding with this treatment, you have 2 options moving forward.

First, you can check out their database to look for an orthodontist nearest you, so you can schedule an appointment yourself. Alternatively, you may also contact Singapore’s Invisalign team so they can pencil you in for an appointment at their centre located along Orchard.

What sets Invisalign apart from other brands is that their treatments can accommodate teenagers. While there are no minimum age requirements for treatment, it’s best to have your child checked by an Invisalign-trained orthodontist to see if they qualify.

From there, your orthodontist will determine which plan suits you best. Depending on your orthodontist, treatment plans may or may not include pre-assessment and mid-treatment procedures, which will affect the overall cost.

Hence, we highly recommend checking in with your chosen orthodontist to see if the price quoted to you is inclusive of these procedures.

What Happens after My Consultation?

Once all the pre-assessment procedures are complete, you can expect your first set of Invisalign aligners to be delivered to your doorstep within 4 weeks. On average, patients have reported changing their aligners every 2 weeks, but this will depend on the complexity of your case.

In terms of monitoring, this will also depend on your chosen clinic. Some orthodontists offer remote monitoring for an additional cost, while others only provide in-person check-ups.

For in-person visits, you can expect to visit your orthodontist every 6 to 8 weeks over the course of your treatment. Again, this will depend on your case, in which case frequency can be shorter or longer.

It all boils down to your chosen clinic, really. But with Invisalign’s large network of orthodontists island-wide, you have plenty of leeway to choose the best one according to your needs and budget.


  • Large network of clinics
  • Suitable for teenagers
  • Suitable for more complex cases
  • Invisalign Centre open daily
  • Installment plans available


  • Relatively expensive
  • Plan inclusions vary per clinic

Customer Reviews

Here are some comments about customers who used Invisalign treatment:

“I am very satisfied with my Invisalign treatment. This help me to be more confident especially when I want to smile. My friends is surprised when they saw me and told me that I am beautiful. 😄 The treatment duration is acceptable which is 1.5 years. Wearing this aligners is very comfortable. I have never developed any mouth ulcers during my treatment period. As this aligners allow us to wear it by ourselves and monitor ourselves for most of the time. It is very convenient and my treatment has never been affected by this COVID situation . My doctor (Dr Huang) is very friendly, professional and responsible.” —董菊, Invisalign Centre Singapore, Google Reviews

“Chanced upon the Invisalign Centre while window shopping after already starting on my Invisalign journey. Was drawn by the different cases available for the aligners. Was welcomed by Jocelyn (hope I spelled her name right), who was very warm and we had a nice chat about my invisalign journey. She seems very knowledgeable as well when I shared about the bite problems I’m getting corrected. Overall a very pleasant experience, and a happy invisalign user. 😊” —Kim Li Ng, Invisalign Centre Singapore, Google Reviews

Another option to consider is Smile Direct Club—a global company that set up shop in Singapore a few years ago. Their line of clear aligners is quite simple, really.

You have the option to choose all-day aligners that you have to wear 22 hours per day or you can get nighttime aligners that require 10 hours of continuous wear. If you’re thinking of exploring this option, read on to know more about their consultation and monitoring processes.

How Do Initial Consultations Work?

Prior to proceeding with treatment, it’s important to know whether you’re a suitable candidate in the first place. Fortunately, you may get a preliminary answer by answering a few questions through their free online tool.

From there, you can book a free 30-minute 3D scan in any of their SmileShops on the island. Yes, it’s free—and you can maximise your visit by raising all your questions about the treatment to their in-house dentist or orthodontist.

While there are a couple of SmileShops in Singapore, their irregular business hours may be a source of confusion for some. Hence, make sure to take note of them prior to your visit.

In most cases though, Smile Direct aligners are only suitable for mild orthodontic cases that require minor movements. We recommend skipping this one if you have severe dental problems that would involve major teeth movement, in which case traditional braces might be the best option.

This will give you the assurance that the treatment will be effective to you.

What Happens after My Consultation?

Once their resident orthodontist/dentist has approved your treatment plan, your clear aligners will arrive in about 4 to 5 weeks. From there, you don’t need to come to their SmileShop for regular dental check-ups.

Instead, your designated dentist or orthodontist will track your progress through their app until the end of your treatment. Accuracy can be an issue here though, and the lack of in-person check-ups may mean a less personalised treatment plan.

As a trade-off, you’re entitled to 24/7 customer care via phone, chat, or video call in case problems arise. If you feel like the aligners aren’t working out at any point of the treatment, just give them a call so they can update your treatment plan and give you new aligners for free.

Otherwise, you can also request for a full refund within 30 days upon receiving your aligners, if you feel like they aren’t for you. These safety nets make them unique in our book, and why we think they’re also worth considering if you have minor dental problems.


  • Free 3D image with dentist consultation
  • Multiple locations
  • 30-day money-back guarantee
  • Satisfaction guarantee
  • 24/7 customer care
  • Virtual monitoring during the treatment and gets free touch ups


  • Suitable for mild cases

Customer Reviews

Check out some reviews by customers who chose Smile Direct Club as their choice of clear aligners:

“My SmileGuide, Shaffiq was extremely helpful in explaining how the aligner works and the treatment process.He was very welcoming and friendly as well which was really admirable and which made the whole interaction really pleasant!! Thank you for making my experience a wonderful one!!! Outstanding and excellent customer service provided + he was assuring and clarified all my doubts and already made me feel confident.” —Kashful, Google Reviews

“Went to Harbourfront Centre for consultation with SmileDirectClub. I’ve asked quite a lot of questions regarding the process, if need to extract my wisdom tooth, payment process & many more. It was a pleasant and smooth consultation with Mr Poh! He was very friendly & patience throughout the consultation. I can’t wait to purchase the aligners as I only went there to consult but now maybe I’ve already decided to purchase them. Received a free whitening kit after the consultation and he mentioned that when I purchased the kit, there will be another whitening products without the LED light which is amazing! I just want to say thank you so much for the great explanation and service!! ❤️” —Nabilah Rahim

And finally, we have WonderSmile—another company that specialises in at-home aligner treatments. Similar to our previous entry, WonderSmile offers daytime aligners for 22 hours of continuous wear and nighttime aligners for 10 hours.

Apart from that, WonderSmile and Smile Direct Club are highly similar in many ways, actually. That said, allow us to outline their process below.

How Do Initial Consultations Work?

Like all clear aligner treatments, you’ll need to have your teeth assessed to see if you’re a suitable candidate or not. WonderSmile also has a free online tool that you can fill up in just a few minutes.

From there, a member of their team will reach out to you to talk about the treatment once you qualify. Naturally, the next step would be to schedule an appointment at their WonderSmile clinic for your 3D scan.

Children as young as 12 years old may also come in for a screening to determine if this treatment is suitable for them—under the supervision and consent of their parents, of course.

During your visit, their resident orthodontist will also discuss your case and walk you through the plan. Take note that scanning and initial consultation fees will cost you $80, which can be deductible from the total cost of the treatment, should you proceed.

Similar to Smile Direct Club, WonderSmile clear aligners work best for patients with mild dental conditions that need very little dental supervision. Hence, we only recommend WonderSmile for cases with mild teeth misalignment.

What Happens after Consultation?

Like everyone else, you can expect your set of clear aligners to arrive 4 to 5 weeks after your initial assessment. Important to note that WonderSmile’s services mostly provide you with a DIY treatment for your teeth.

While remote monitoring is available throughout your treatment, you’ll have to make sure that you wear your clear aligners as prescribed so you can achieve results.

The absence of in-person mid-treatment consultations may mean that you have to rely purely on their remote monitoring service, which may not be as precise and stringent compared to others.

WonderSmile does have a lifetime guarantee, though, which entitles you to free additional treatments if your teeth ever shift out of alignment. And yes, this guarantee will be in place for the rest of your life—but there’s a catch.

Note that the guarantee will only cover teeth originally involved in your WonderSmile treatment plan. This means that the guarantee may be voided once you undergo dental or orthodontic procedures following the end of your WonderSmile treatment.

So make sure to factor these conditions in prior to scheduling your scan.


  • Suitable for patients above 12 y.o
  • 30-day money-back guarantee
  • Satisfaction guarantee
  • Relatively affordable


  • Suitable for mild cases only
  • Virtual monitoring only
  • Only 1 clinic available

Customer Reviews

See what some of Wondersmile’s past customers have to say about the treatment:

“Carmen is really helpful in answering all questions and making me feel comfortable throughout the process. The team is also really speedy with their response and updates! Can’t wait to try out the clear braces!!” —Fan Yu Qing, Google Reviews

“Carmen was detailed in her explanation and also very hospitable in her approach. The whole process was pleasant and quick (<30min) no pain at all, only some short periods of mild discomfort when my teeth were being scanned, especially trying to reach nooks and crannies. Every step was well explained and I enjoyed my time there. Have yet to begin my treatment so I cannot vouch for the end result yet. Looking forward to receiving my WonderSmile box!” —Amanda Er, Google Reviews

Conclusion: Which One’s for You?

At the end of the day, the best choice of clear aligners all boils down to your needs and budget. Ask yourself this preliminary question: How severely misaligned are my teeth?

If your answer to that question is “quite severe,” then the best course of action is to have your teeth checked by an Invisalign-trained orthodontist. They’re the best choice for patients with moderate to complex alignment issues.

This also means that your teeth will need regular hands-on monitoring to make sure everything’s in order. And with the presence of regular check-ups with your orthodontist throughout the Invisalign treatment, rest assured that your case will be handled with utmost care.

Just be prepared to shell out a huge sum for this treatment, though. After all, they’re the most expensive option out of our other entries.

Now, if you only need some alignment corrections to your front teeth, then Zenyum can help you with that. While check-ups aren’t that frequent, you’ll still have to go to your orthodontist 3 times.

Otherwise, monitoring will continue through its app, which will require you to upload photos of your teeth regularly. Not to mention that Zenyum is significantly more affordable than Invisalign, too.

This makes Zenyum a good option for those with a limited budget and only need mild to moderate corrections, but still would like a limited hands-on approach towards their treatment.

Finally, you can consider Smile Direct Club or WonderSmile if you have minor alignment issues that require very little dental supervision.

While they offer remote monitoring, these companies don’t really offer strict monitoring processes as part of their treatments, unlike Invisalign and Zenyum.

This means that the success of the treatment is entirely up to you, and how much you adhere to the procedures that they’ve set in place for your treatment. The biggest advantage of these companies is that they’re more affordable than our other entries.

Beyond budget, Smile Direct Club or WonderSmile might give you the treatment you need if you only need minor corrections without the hassles of regular check-ups.
