Invisalign for Adults

Can Adults Have Invisalign?

Yes. There is no upper age limit for Invisalign, and adults now make up a large share of aligner patients. What decides whether it suits you is not your age but the health of the gums and bone around your teeth, the kind of movement you need, and whether you can wear aligners for 20 to 22 hours a day.

At Comely Bank Dental, Invisalign is led by Dr Jonathan Wardell, who has been an Invisalign Diamond Apex Provider every year from 2022 to 2026, a status held by the top 1% of Invisalign providers in Europe. Treatment starts from £3,000, refinements and Vivera retainers are included, and the first consultation is free.

Adult treatment often has a different goal from teenage orthodontics. Rather than a textbook bite, many adults want front teeth that are easier to keep clean, a smile they are comfortable with in photographs, or teeth positioned so that future dental work is simpler and less invasive. A good plan starts from what you want and what your mouth can safely do.

What Can Invisalign Correct in an Adult Mouth?

Aligners move teeth gradually through a series of slightly different trays. Used well, they can manage most of the problems adults bring to us:

• Crowding, from one overlapping tooth to more noticeable crowding across the front teeth
• Gaps, including spaces that have opened up over the years
• Rotated or tipped teeth, often with small tooth-coloured attachments that give the aligner something to grip
• Deep bites, where the upper front teeth cover too much of the lower ones and wear them down
• Some open bites and crossbites, depending on their cause
• Relapse after braces you had as a child or teenager
• Preparation for other treatment, such as uprighting a tilted tooth to make room for an implant, or aligning teeth before composite bonding

That last use is underrated. Moving teeth into better positions first can mean bonding or veneers need much less tooth reduction, and sometimes the alignment alone gives the result someone was hoping for.

Where Does Invisalign Reach Its Limits?

Being clear about what aligners cannot do matters as much as what they can. Invisalign is not the right answer when:

• The problem lies in the jaws rather than the teeth. A significant mismatch in jaw size or position may need fixed braces combined with jaw surgery, planned by a hospital orthodontic team. We would refer you rather than offer a compromise.
• Gum disease is active. Moving teeth through inflamed tissue and shrinking bone can make things worse. This is treated first.
• There is untreated decay or a failing filling. These are dealt with before scanning, so the aligners fit the teeth you will actually have.
• Teeth are missing. Aligners can open or close a space, but they cannot replace a tooth.
• The concern is shape or colour. Straight teeth that are chipped, worn or stained are still chipped, worn or stained. Whitening or bonding may be needed as well.
• The wear time isn't realistic for you. Aligners that spend the day in their case do nothing.

Some movements are also less predictable with aligners, such as large rotations of rounded lower premolars, or bringing down a tooth that sits well above its neighbours. Attachments and refinements often handle these. Where they won't, fixed braces with an orthodontist are the better tool, and we will tell you so.

Is Invisalign Safe If I've Had Gum Problems?

Often it is, but timing matters. Teeth move because the bone around them remodels, so gums and bone need to be stable before treatment starts. If your gums bleed when you brush, or you have been told you have periodontal disease, we check gum pocket depths and X-rays first and arrange gum treatment if it's needed. Once things are stable, aligners can be used safely in many people with a history of gum disease, sometimes with gentler, slower movements.

Two things adults should know in advance:

• Small dark triangles can appear between the front teeth once crowding is corrected, especially where gums have receded with age. The aligners don't cause them; the overlap was hiding the space. Minor reshaping or bonding can reduce them.
• Aligners do not reverse recession. They can sometimes move a tooth back into better bone support, but lost gum does not grow back.

Removable aligners are generally easier to clean around than fixed braces, and regular visits with our hygienist help keep the gums healthy while the teeth are moving.

What About Crowns, Fillings, Implants and Worn Teeth?

A mouth with decades of dentistry needs more planning than one with none, but that rarely rules Invisalign out.

Crowns and veneers. It is the root that moves, so crowned teeth can be straightened. Attachments bond less reliably to porcelain or metal than to natural enamel, so we may use a different bonding method or plan around that tooth. If an old crown is already due for replacement, it usually makes sense to replace it after alignment, so the new one is made for the final position.

Large fillings. These are checked beforehand, and anything cracked or leaking is repaired first. Some fillings are better redone at the end, once the bite has settled.

Implants. An implant is fused to the bone and will not move. It stays put while other teeth move around it, and the plan is built with that in mind.

Worn teeth. Wear often comes from crowding or a deep bite that overloads certain teeth, or from grinding at night. Aligning first can create room to rebuild worn edges with bonding while removing far less tooth. If you grind, you may see marks on your aligners, but they are not a long-term replacement for a night guard.

Can Invisalign Fix Teeth That Moved After Braces?

This is one of the most common reasons adults come to see us. Teeth keep moving throughout life, and the lower front teeth in particular tend to crowd with age, braces or not. If retainers were worn for a year or two and then given up, some relapse is very likely.

The encouraging part is that relapse cases are often relatively short. The roots are usually close to where they were left, and the movement is commonly limited to the front teeth. Some people need only a few months of aligners; others need longer, particularly if the bite has changed too. Your scan and treatment plan will show which applies to you.

The less welcome part is that it will happen again without retention. Teeth that have moved once have shown they want to move, so we plan for long-term retainer wear from day one. Vivera retainers are included in Invisalign treatment with us.

How Many Hours a Day, and How Does It Fit In?

Aligners only work while they are in. The standard is 20 to 22 hours a day: out to eat and to drink anything other than plain water, then straight back in after brushing or rinsing. Most adults move to a new set every one to two weeks, as advised.

Some honest notes on fitting this around work and family:

• Meals and meetings. Long lunches and grazing through the day are the biggest threat to wear time. Many patients find they snack less.
• Coffee, tea and wine. Take the aligners out. Hot drinks can distort them, and coloured or sugary drinks sit against the teeth under the plastic.
• Speech. A slight lisp is common for a day or two with a new set and usually settles quickly, even for people who present or teach.
• Pressure. Expect teeth to feel tight for a day or two after each change. That is the aligner doing its job.
• Smoking and vaping. Both stain aligners and are bad for gums while teeth are moving.
• Travel. Pack your current and next aligners, and keep the previous set as a spare.

If life makes 20 hours a day unrealistic right now, it is better to wait than to start and fall behind.

Your Free Invisalign Consultation in Edinburgh

The consultation is free, and it is a conversation as much as an examination.

• Your concerns. We start with what you would like to change, and what matters most if not everything is achievable.
• A health check. Dr Wardell looks at your teeth, gums, existing dental work and bite. X-rays may be needed if you haven't had recent ones.
• An iTero scan. Instead of putty impressions, a small wand records a 3D digital model of your teeth in a few minutes.
• A simulation. The scan can show a preview of how your teeth might look after treatment. It's a guide, not a promise, and results vary.
• Options and fees. Invisalign starts from £3,000, depending on complexity. If aligners aren't the best route, we will talk through the alternatives, including fixed braces, bonding or simply leaving things as they are.

If you go ahead, a detailed plan shows each stage of tooth movement, and you review it before any aligners are made. Your fee is agreed in a written treatment plan before treatment starts, and it includes refinements and Vivera retainers. You can book a free consultation online or call 0131 332 3971.
