What is Invisalign®?

The Invisalign® Clear Aligner system can offer patients the opportunity to have the smile of their dreams with a more discrete method of treatment. Invisalign is clear, removable, and extremely effective when used correctly.

Invisalign offers a discreet orthodontic treatment option with a series of clear, removable aligners. These aligners are designed to straighten your teeth without the need for brackets or wires.

What are the benefits of Invisalign®?

Aesthetic - One of the most obvious benefits of the Invisalign® system is their aesthetics. With the Invisalign Clear Aligners, your orthodontic process will be virtually invisible to those around you. With this system, patients are able to remove their aligners to brush and floss eliminating the risk of any staining after treatment. We suggest that patients make sure to put their aligners on right after they finish eating, brushing, or flossing.

Time efficient - With Invisalign treatment, fewer appointments at our office will be required, and generally your appointment time should be shorter. On average, with Invisalign treatment at Terenure Orthodontics, appointments are needed every 10-12 weeks. At your consultation appointment, we will give you an idea of how long your treatment will take before you decide to get started.

How does Invisalign® work?

The Invisalign system is a set of customized clear aligners that are easily removable, enabling teen and adult patients to straighten their smile without anyone knowing they are going through orthodontic treatment. Here are a few points to better explain the Invisalign system:

  • Wear each set of aligners for approximately 2 weeks
  • Remove to eat, drink, brush, and floss
  • Teeth will gradually move with each set of aligners
  • Visit Terenure Orthodontics every 8-10 weeks
  • Total treatment time averages 6-15 months depending on the case
  • Average number of aligners needed is between 18-30

How much does Invisalign® Cost?

Due to the bespoke nature of the Invisalign system, the costs of this treatment tend to be more expensive the traditional braces. Nevertheless, the costs do vary depending on severity and treatment goals.

We offer a range of payments plans as well as discounts for up front payments and it's important not to forget that you are entitled to 20% back on the cost of treatment with the Med 2 Form.

The Process

Initial Consultation

This appointment is to discuss your goals with one of our specialist orthodontists. It may also involve your dental and medical history, a physical examination of your teeth and jaw, X-rays, and possibly impressions of your teeth to create models.

Treatment Planning

The orthodontist will review the X-rays, photos, and examination results to devise a specific plan for moving your teeth into the correct position. This plan will include the estimated length of treatment, cost of treatment and any preparatory work needed.


This might involve dental cleaning, addressing any existing dental issues like cavities, and possibly extracting teeth to create space for adjustments. Once these issues have been addressed, it's time to move onto the next phase!

Aligner fitting

Your first appointment will involve placing the attachments onto your teeth and giving you your first series of aligners. This process is a pain-free and simple process taking only about 20 minutes. We will go through all of the necessary instructions at this stage too.

Aligner Monitoring

During treatment we will monitor your progress with appointments every 8-12 weeks, to ensure your treatment is on track. We will usually require refinements, where we will take another impression or scan and send this away for a new set of aligners to be made.

Removal of Attachments

At this appointment, the composite attachments that were placed onto you teeth are removed carefully in a process that usually takes 30-40 minutes. We will usually place a metal fixed retainer behind you top and bottom teeth at this stage too and provide you with clear retainers to be worn at night-time.

Aftercare & Retention

To keep your teeth in their new position after the braces are removed, most patients will need to wear a retainer full time for a period following the removal of braces, transitioning to night-time wear to ensure teeth do not shift back to their original positions. Read more here.

How does Invisalign® work?

The Invisalign system uses clear aligners to gradually move teeth into place. Aligners should be worn 22 hours a day for about 2 weeks each, with office visits every 10 to 12 weeks to monitor progress. After treatment, a retainer is used to maintain the new alignment. Treatment averages 6 to 18 months.

Will Invisalign® yield the same outcomes as braces?

Yes, Invisalign and braces can deliver similar results, with Invisalign offering effective outcomes through its advanced technology in tooth movement.

I have an upcoming important event. Can I remove my aligners for that day?

Yes, aligners can be temporarily removed for special events, but it's important to wear them again promptly afterward and extend wearing time to compensate.

Can I engage in sports while wearing aligners?

For sports, it's recommended to use a separate mouth guard that adjusts as teeth shift, since Invisalign doesn't offer the same protection as a sports guard.

Is Invisalign better than braces?

Invisalign and braces each have advantages, with Invisalign being more aesthetic and removable, and braces often more effective for complex issues. The best choice depends on individual needs.

How much does Invisalign® cost in the US?

Invisalign costs in the range from 3,000 to 7,000, varying based on treatment complexity, duration, and location. A consultation is needed for an exact quote.

How much does Invisalign® cost in Ireland?

In Ireland, Invisalign costs between 3,500 to 6,500, with variations depending on treatment length and complexity. Consultation is recommended for accurate pricing.

What are the disadvantages of Invisalign®?

Disadvantages include the need for discipline in wearing aligners, potential for slower results in complex cases, higher costs than traditional braces, and the need for regular cleaning.

Is Invisalign® Painful?

Invisalign may cause mild pressure initially but is generally not painful. Discomfort usually subsides quickly after a new aligner is put in.

Why is Invisalign® so expensive?

Invisalign's cost reflects its custom manufacturing, advanced technology, and the benefits of a removable, nearly invisible system, including orthodontist visits and adjustments.

Is Invisalign® a permanent fix?

Invisalign can offer a permanent solution if followed by consistent retainer use post-treatment to maintain alignment.

What is the success rate of Invisalign®?

Invisalign has a high success rate for mild to moderate issues, with success depending on patient compliance and case complexity.

Are Invisalign® cheaper than braces?

Invisalign is often more expensive than traditional braces, though the cost difference has decreased. Prices vary based on individual treatment requirements.

Can you eat with Invisalign®?

Invisalign aligners must be removed during meals to prevent damage, allowing more dietary freedom compared to braces but requiring careful aligner maintenance.

Do orthodontists prefer Invisalign® or braces?

Treatment preference, like Invisalign or braces, is based on individual case needs. Invisalign is preferred for aesthetic reasons and simpler cases, while braces may be better for more complex issues.

Is Invisalign® cheaper if your teeth aren't that bad?

Invisalign may be less expensive for simpler, shorter treatments, but costs are generally based on treatment complexity and duration, with less severe cases potentially costing less.
