What Is Invisalign and How Does It Work?

In the past, orthodontic treatment was usually associated with bulky metal braces, uncomfortable adjustments, and long treatment times.  However, advances in dental technology have transformed the field, and one of the most notable innovations is Invisalign.

This discreet, comfortable, and effective teeth-straightening system has become increasingly popular in Dublin and all across Ireland over the past decade.

From teenagers to adults, more and more people are choosing Invisalign as their preferred orthodontic solution, for both aesthetic and practical reasons.

It’s a modern, nearly invisible way to transform your smile, without the brackets, wires, or hassle.

At Chatham Dental, we specialise in modern, patient-focused orthodontic care.

And, as Invisalign Elite Providers, we’ve helped hundreds of patients achieve straighter, healthier smiles using this advanced aligner system. In this blog, we’ll explain:

  • What Invisalign is.
  • How Invisalign works to move your teeth.
  • The benefits of Invisalign.
  • How Invisalign is different from braces.
  • What your daily routine looks like.
  • And what to expect from Invisalign treatment at Chatham Dental in Dublin.

From your first consultation to your final aligner, we’re here to make the entire experience smooth, stress-free, and tailored to your goals.

So, What Is Invisalign?

Invisalign is a type of clear aligner system that gradually straightens your teeth over time using custom-made, removable trays instead of fixed metal braces. It’s popular because the aligners are:

  • Clear (nearly invisible when worn).
  • Removable (you take them out to eat and brush).
  • Comfortable (no wires or sharp edges).

The Invisalign system is backed by decades of research, and millions of people worldwide have used it to achieve straighter, healthier smiles, often without anyone noticing they’re wearing aligners at all.

How Does Invisalign Work?

Each set of Invisalign aligners is carefully designed to move specific teeth, in specific directions, at the right time.

Aligners apply gentle, targeted pressure to shift teeth millimetre by millimetre.

As you switch to a new aligner (usually every 1–2 weeks), your teeth gradually move closer to their ideal position as mapped out in your 3D digital treatment plan.

The aligners are made from SmartTrack® material, which is smooth, flexible, and designed for both comfort and precision.

And because they’re removable, Invisalign allows you to eat, brush, and floss like normal, with fewer interruptions to your daily life.

Think of Invisalign like a gentle, step-by-step guide for your teeth.  Here’s how it works:

Step 1: Custom 3D Scan

Your Invisalign journey starts with a digital scan of your teeth (no messy impressions). This scan creates a 3D model of your mouth so your dentist can map out your entire treatment plan.

Step 2: Personalised Aligners

Based on your scan, you’ll receive a series of clear aligners, each slightly different, to guide your teeth into better alignment, little by little.

Step 3: Wear and Switch

You’ll wear each set of aligners for about 1 to 2 weeks, for 20–22 hours per day. As you change aligners, your teeth move gradually into the desired position.

Step 4: Enjoy Your Smile!

At the end of your treatment, you’ll have a straighter smile and a set of custom retainers to keep your results in place.

What Does Invisalign Do to Your Teeth?

Invisalign is designed to gradually move your teeth into a healthier, more aligned position using a series of custom-made, clear aligners.

Each aligner applies gentle, controlled pressure, which helps guide your teeth over time without the need for metal brackets or wires. Here are some of the most common problems it can help with and what they actually mean:

Crowded teeth

When there isn’t enough space in your jaw for your teeth to fit properly, they can overlap or twist. Crowding can make brushing and flossing harder, increasing the risk of decay. Invisalign helps create the space needed for a straighter, healthier smile.

Gaps between teeth

If you have spaces or gaps between your teeth, it can affect both appearance and oral health. Food can get trapped, and gums can feel unprotected. Invisalign can close these gaps over time for a more even smile.

Overbite

This is when your top front teeth stick out too far over your bottom teeth. A slight overbite is normal, but if it’s too deep, it can cause wear, jaw strain, or difficulty biting into certain foods. Invisalign can help bring the teeth into better alignment.

Underbite

An underbite happens when your lower teeth sit in front of your upper teeth. This can make chewing or speaking more difficult and may lead to jaw discomfort. Invisalign can often correct mild to moderate underbites.

Crossbite

This is when some upper teeth sit inside the lower teeth when you bite down, instead of outside. Crossbites can wear down teeth over time and sometimes lead to gum issues. Invisalign aligners help gradually move the teeth into a healthier bite.

Open bite

In an open bite, your top and bottom teeth don’t touch when your mouth is closed — leaving a gap. This can make it hard to chew properly or pronounce certain words. Invisalign helps to gently close that space by moving teeth vertically.

The Benefits of Invisalign

It’s easy to see why Invisalign has become one of the most popular orthodontic treatments in Ireland.  Here are some of the reasons patients are choosing Invisalign at Chatham Dental:

1. Virtually Invisible

Invisalign aligners are made from clear, medical-grade plastic that’s almost invisible when worn. Most people won’t even notice you’re wearing them, making them perfect for professionals, teens, or anyone who prefers a low-profile look.

2. Comfortable and Smooth

Unlike traditional braces with wires and brackets, Invisalign trays are smooth and custom-fitted to your teeth. That means less irritation to your cheeks and gums, and no emergency visits for broken brackets or poking wires.

3. Removable for Eating and Cleaning

One of Invisalign’s biggest advantages is that you can take the aligners out. You can eat all your favourite foods without restrictions, and brushing and flossing are just as easy as before. No awkward tools required.

4. Fewer Dental Visits

Invisalign treatment requires fewer check-ups than braces. You’ll still see your dentist to monitor progress, but there’s no need for wire tightening or bracket adjustments, making it easier to fit into your schedule.

5. Predictable Results

Using 3D digital scans (such as the iTero Element scanner), your entire Invisalign treatment plan is mapped out from the start, so you’ll know exactly what to expect and see how your smile will transform, step by step. This transparency builds confidence and motivates patients to commit to the process.

6. Shorter Treatment Times

In some cases, Invisalign treatment can be faster than traditional braces, depending on the complexity of the dental issue. Patients appreciate the possibility of achieving results in as little as six months for mild cases.

The Growing Popularity of Invisalign in Dublin

Over the past decade, Invisalign has become a go-to solution for people in Dublin and across Ireland who want to improve their smile with minimal disruption to their daily lives.

From students and working professionals to brides-to-be and parents investing in themselves, more people are choosing Invisalign for its discreet design, proven results, and modern approach to orthodontics.

At Chatham Dental, we’ve seen this growing demand first-hand.

Here are some of the key reasons behind Invisalign’s rise in Dublin:

1. A Lifestyle Fit for the Modern Patient

One of the biggest drivers of Invisalign’s success is how seamlessly it fits into busy lives. Unlike braces, the aligners are removable, making them perfect for work meetings, social events, weddings, or sports. There are no dietary restrictions, and cleaning is quick and easy, which makes the treatment especially appealing for active, on-the-go individuals.

2. Influencer and Celebrity Endorsements

Influencers, celebrities, and lifestyle bloggers have openly documented their Invisalign journeys on Instagram and TikTok, normalising orthodontic treatment for adults and showing how discreet, transformative, and confidence-boosting it can be.

3. The Power of Digital Marketing

Dental practices across Ireland are now using before-and-after photos, real patient testimonials, and educational videos to showcase Invisalign results. This increased visibility has helped more people understand what’s possible and how achievable it really is.

4. Accessible Financing and Widening Availability

The ability to finance Invisalign through interest-free payment plans has opened the door for many who previously felt it was out of reach. Plus, with more general dental practices (not just orthodontists) now certified to offer Invisalign, patients in both rural and urban areas can easily access treatment close to home.

5. Trusted, Certified Providers

Success with Invisalign isn’t just about the aligners. It’s about who guides your treatment. At Chatham Dental, we’re proud to be recognised as Invisalign Elite Providers and have a professional, talented, and knowledgeable team trained in the latest techniques.

6. Combined with Other Smile Enhancements

Invisalign is often offered as part of a complete smile makeover, alongside treatments like teeth whitening or composite bonding, giving patients not just straighter teeth, but a full cosmetic transformation.

7. A Post-Pandemic Boost

Interestingly, the pandemic also played a role. With fewer in-office visits required, Invisalign’s low-maintenance nature made it ideal during lockdowns when clinic visits were limited. As cosmetic dentistry continues to grow in Ireland, and patients demand treatment that’s discreet, flexible, and effective, Invisalign has become a natural, trusted choice.

Invisalign Vs Braces

At Chatham Dental, we offer both Invisalign and traditional braces, because no two smiles are the same, and neither are treatment needs.

Feature Invisalign Traditional Braces
Appearance Clear, virtually invisible aligners Metal brackets and wires are visible
Removability Removable for eating, brushing, and special occasions Fixed to teeth until treatment is complete
Comfort Smooth plastic trays, no wires or brackets May cause irritation from wires and brackets
Oral Hygiene Easy to brush and floss normally Requires extra tools (floss threaders, interdental brushes)
Diet Restrictions None, just remove aligners to eat Must avoid hard, sticky, or chewy foods
Appointments Fewer visits, no wire adjustments Regular in-chair adjustments and monitoring
Technology 3D computer-guided planning moves teeth in multiple directions at once Manual adjustments by orthodontist
Best For Mild to moderate cases, lifestyle-conscious patients Complex or severe orthodontic cases
Treatment Monitoring Digital scans and progress tracking Visual assessments and manual adjustments
Suitability Teens and adults seeking a discreet, flexible option Patients of all ages, especially with complex needs
Duration ~6–12 months on average (varies by case) ~18–36 months on average (depending on severity of the case)

Ultimately, the right choice depends on your teeth, goals, and preferences. Our team will guide you through all your options and help you make the best decision for your smile.

What’s the Daily Routine Like?

Daily life with Invisalign is surprisingly simple. Here’s what to expect:

  • Wear aligners for 20–22 hours a day.
  • Remove them to eat, drink (except water), brush, and floss.
  • Switch to a new set of aligners every 1–2 weeks (your dentist will guide you).
  • Clean your aligners daily with lukewarm water or cleaning crystals.
  • Attend check-ups every 6–8 weeks to monitor progress.

Most people get used to wearing aligners quickly, and because they’re nearly invisible, it’s easy to feel confident wearing them at school, work, or social events.

What’s Next For Your Smile?

The growing popularity of Invisalign in Dublin and all across Ireland reflects a wider shift in how people view orthodontic treatment.

Teeth straightening is no longer seen as an uncomfortable, purely functional process.

It’s now a lifestyle-friendly investment in confidence, appearance, and self-care.

With its blend of comfort, convenience, and clear results, Invisalign has redefined orthodontics for everyone. And this is just the beginning.

As dental technology continues to evolve, we’re seeing faster, more comfortable treatments thanks to innovations like AI-guided planning and smarter aligner materials.

At the same time, the way we think about cosmetic dentistry is changing, too.

More people are seeing it as part of their overall well-being, not just their appearance, and Invisalign fits perfectly into that mindset.

At Chatham Dental, we help patients take control of their smile in a way that’s simple, supportive, and tailored to their lifestyle.

Still Have Questions? Here Are a Few Frequently Asked Questions about Invisalign

Q1. Is Invisalign as effective as braces?

Yes. It works especially well for mild to moderate crowding, spacing, and bite issues. For more complex cases, we’ll assess whether Invisalign or braces are the better option during your consultation.

Q2. How long does Invisalign treatment take?

Most patients at Chatham Dental complete Invisalign in 6 to 12 months. More complex cases may take a little longer. You’ll get a clear idea of your timeline after your 3D scan and treatment planning.

Q3. Is Invisalign painful?

Not painful, but you may feel some mild pressure or discomfort for the first day or two after switching to a new aligner. This is totally normal and means your aligners are working. Most patients find Invisalign far more comfortable than braces.

Q4. What happens after Invisalign treatment ends?

At the end of your treatment, you’ll receive a custom retainer to maintain your new smile. Wearing it as instructed is crucial to prevent your teeth from shifting back over time.

Q5. How much does Invisalign cost?

The cost varies depending on the complexity of your case, but we offer interest-free payment plans to make treatment manageable. You’ll receive a full quote and breakdown at your free consultation — no surprises.
