Invisalign for adults: straightening teeth at any age
Most adults who come to us for Invisalign fall into one of two groups. Some have teeth that have slowly crowded over the years. Others had braces as a teenager, stopped wearing their retainer, and have watched their teeth drift back.
Invisalign uses clear, removable aligners that fit around work, meals and meetings. This guide covers who it suits, what gets checked first, and how it works alongside other dental care. A free 30-minute consultation with a 3D scan will show you what treatment could involve for your teeth.
Teeth moved after braces?
It’s one of the most common reasons adults book in with us. Teeth keep shifting slightly throughout life, and after braces they tend to drift back towards where they started. A retainer, or a fixed wire behind the teeth, is what holds them in place.
If the retainer stopped being worn or a fixed wire was never fitted, the front teeth are usually the first to move. The good news is that Invisalign can often bring them back into line, even years later.
Adults also often come to us with
-
Crowding that has slowly worsened over time
-
Gaps that have opened up between teeth
-
Overlapping front teeth that are harder to clean
-
Bite concerns, such as an overbite or crossbite
Once your teeth are straight, wearing a retainer as advised is what keeps them there. Your dentist will talk you through the options at the end of treatment.
Am I too old for Invisalign?
There’s no upper age limit. Teeth can be moved at any age, so what matters more is the health of the gums and bone that hold them. Your dentist checks these at the free consultation before recommending treatment.
Gum health
Healthy gums are needed before teeth are moved. If there are signs of gum disease, that’s treated first.
Bone support
The 3D scan and x-rays show how much bone is holding each tooth, which guides how the teeth can be moved.
Existing dental work
Fillings, crowns and bridges are factored into the plan, and any work that needs attention is looked at first.
Adult braces or Invisalign?
Both can straighten adult teeth in the right cases. Many adults choose Invisalign because the aligners are clear and come out to eat, while braces stay on and can suit more complex bite corrections.
Invisalign may suit you if
- You’d prefer something less noticeable at work
- You want to eat and brush as normal
- Your teeth have moved since you had braces
- You can wear aligners 20 to 22 hours a day
Braces may suit you better if
- Your bite needs more complex correction
- You’d rather not take anything in and out
- Wearing aligners most of the day wouldn’t suit you
- Your dentist recommends it after the scan

Invisalign before veneers or cosmetic work
If you’re thinking about veneers, crowns or other cosmetic dentistry, your dentist may suggest Invisalign first. Moving the teeth into a better position before cosmetic work can mean less of the natural tooth needs to be reshaped, and gives a more even base to work from.
Not everyone needs this step. It depends on how your teeth sit now and what you’d like to change, which your dentist will go through with you.
- 1
Plan the end result
Your dentist looks at both the straightening and the cosmetic work together, so each step sets up the next.
- 2
Straighten with Invisalign
The aligners move your teeth into position first, with regular check-ins along the way.
- 3
Whitening, if it’s part of the plan
Whitening is usually done before veneers or crowns, so their shade can be matched to your natural teeth.
- 4
Cosmetic work and retainers
Veneers or crowns are then made for your new tooth positions, and a retainer helps hold everything in place.
Our Invisalign Services Include
Fitting Invisalign around work and life
Aligners need to be worn 20 to 22 hours a day, but they come out to eat, drink anything other than water, and brush. Most adults settle into the routine within the first couple of weeks.
Our practices are open from 7am to 7pm on weekdays and on Saturday mornings, so check-ins can happen before work, after work or on the weekend.
- 1
Meals and coffee
Take aligners out for meals, coffee and anything other than plain water, then brush before they go back in.
- 2
Meetings and presentations
Some people notice a slight lisp for the first few days with a new set of aligners. It usually settles as your tongue gets used to them.
- 3
A case in your bag
Keeping the case with you means aligners go somewhere safe at lunch, rather than into a napkin.
- 4
Regular check-ins
Your dentist checks how your teeth are moving and gives you your next sets of aligners, at times that fit your week.
What does Invisalign for adults cost?
The cost depends on how much your teeth need to move, the type of Invisalign and how long treatment takes. Your dentist gives you an exact quote at the free consultation, before you decide anything.
Interest-free payment plans
Spread the cost with interest-free plans through Humm, with approval and terms assessed by Humm. Afterpay, Zip and TLC are also available.
Private health insurance
If your extras cover includes orthodontics, your fund may contribute. Orthodontic cover often has a longer waiting period and an annual or lifetime limit, so it’s worth checking with your fund.

A quick note: Invisalign is an orthodontic treatment, and results vary from person to person depending on your individual case and how consistently the aligners are worn. This information is general in nature and intended for adults; your dentist will discuss what’s realistic for you at your consultation.
Invisalign for adults FAQs
Questions adults ask us most. Anything else, your dentist can answer at the free consultation.
Am I too old for Invisalign?
No, there’s no upper age limit for Invisalign. Teeth can be moved at any age. What matters more is the health of your gums and the bone that supports your teeth, which your dentist checks at the free consultation.
Can Invisalign fix teeth that moved after braces?
Often, yes. Teeth commonly drift back after braces if a retainer wasn’t worn or a fixed wire wasn’t fitted. Invisalign can usually bring them back into line, and a retainer afterwards helps keep them there.
Do I need a retainer after Invisalign?
Yes. Teeth naturally try to move back after straightening, so a retainer is what holds them in their new position. Your dentist will recommend a removable retainer, a fixed wire behind the teeth, or both.
How long does Invisalign take for adults?
Many adults finish treatment in around 12 to 18 months, though minor cases can be shorter and complex cases longer. Your dentist gives you an estimated timeframe after your 3D scan.
Can I get Invisalign if I have crowns or fillings?
Usually, yes. Crowns, fillings and bridges are factored into your treatment plan. Your dentist checks your existing dental work first and will let you know if anything needs attention before you start.
Can I get Invisalign if I’ve had gum disease?
Gum disease needs to be treated and under control before teeth are moved. Once your gums are healthy, Invisalign may still be an option, and your dentist will keep a close eye on your gum health during treatment.
Should I get Invisalign before veneers?
Sometimes. If your teeth are crowded or out of line, your dentist may suggest Invisalign first so your teeth are in a better position before veneers or crowns. It can mean less of the natural tooth needs to be reshaped. Whether you need it depends on your teeth.
Is Invisalign or braces better for adults?
Both can straighten adult teeth in the right cases. Invisalign suits many adults because the aligners are clear and removable, while braces can suit more complex bite corrections. Your dentist will recommend what suits your teeth after the scan.
Does Invisalign hurt?
Most people feel some pressure or tightness for a day or two after switching to a new set of aligners. This is a sign the aligners are working and usually settles quickly.
Will Invisalign affect my speech?
Some people notice a slight lisp for the first few days with new aligners. It usually settles as your tongue adjusts.
How many hours a day do I wear Invisalign?
Aligners need to be worn 20 to 22 hours a day. They come out to eat, drink anything other than water, and brush your teeth.
Can I drink coffee with Invisalign?
Take your aligners out for coffee and any drink other than plain water. Hot and sugary drinks can stain the aligners or get trapped against your teeth. Brush or rinse before putting them back in.
How much does Invisalign for adults cost?
