Invisalign FAQs


Dr Brian Mulgrew (Specialist Orthodontist) has been treating patients with Invisalign since 2009. He is one of Northern Irelands leading Invisalign providers. Here are his thoughts to your questions on Invisalign.

What is Invisalign?

Invisalign is a virtually invisible method of straightening your teeth. It works by wearing a series of clear gum shields (aligners) which gently guide your teeth into position.

How does Invisalign work?

Invisalign works by gently moving your teeth into position using custom made aligners. You change these every 1 to 2 weeks.

Is Invisalign only for very mild cases?

No Invisalign can be used to treat nearly all cases. Invisalign is just a tool to straighten your teeth. It is prescribed by the clinician treating you. If you want your teeth straightened with Invisalign we would recommend that you attend a Specialist Orthodontist experienced in the use of Invisalign to achieve optimum results.


Is Invisalign as good as braces?

Yes in the hands of a specialist orthodontist experienced in Invisalign. I find that anything I can treat with braces I can also treat with Invisalign.

Invisalign is constantly improving and innovating. It has revolutionised orthodontics and it has removed barriers for lots of people who were very unhappy with their smile but suffered in silence because they were worried about the appearance of traditional fixed braces.

Is Invisalign painful?

Every patient experiences tooth movement differently. In my experience patients describe it as uncomfortable in the first few weeks or tender rather than painful. It is normal to experience a little bit of discomfort as teeth move and can be managed with normal painkillers. Some people experience no discomfort at all. Compared to traditional braces Invisalign is much less bulky. It does not have any wires or brackets which can annoy or rub the inside of your mouth.

What Does It Feel Like?

My patients tell me they initially feel like a slim and lightweight retainer. This becomes less noticeable each day and with each aligner change. They do feel the presence of the aligner at first, and may have a small lisp as they get used to it. As you remove them completely when eating – which is a huge advantage over normal braces, you will notice no difference here and can eat what you like.

What are the advantages of Invisalign?

I call it the 4 C’s

Cosmetic – Invisalign is clear, you will find that most people do not notice you’re wearing them.

Clean- You remove Invisalign for eating and drinking therefore unlike traditional braces you do not have to worry about food getting caught around the brace. You are much less likely to get decay or inflamed gums with Invisalign.

Comfortable – It does not have any wires or a bracket so will not rub as much as a traditional brace.

Convenient – Invisalign is removable so it can be removed for 2 hrs a day. This means that if you have a music recital or are going out for a special meal you can take it out and so long as you maintain 22 hours wear.

What is the Cost of Invisalign?

Your smile is a worthwhile investment. Invisalign varies in price depending on the type invisalign used, e.g I7, LIte or full Invisalign. It also depends on the complexity of your problem.
At Mulgrew Orthodontics we offer all our patients interest free finance over 18mths to cover the cost of their Invisalign Treatment. For example, if you put a deposit of £900, in an Invisalign case you will then pay as little as £116 per month.
