Invisalign vs Mail-Order
Aligners sent to your door can look like the same treatment for less money. Sometimes the end result is similar, but what happens before and during treatment is very different, and that's where the risks lie.
Are at-Home Aligners as Good as Invisalign From a Dentist?
The main difference is not the plastic but the care around it: Invisalign at Comely Bank Dental in Edinburgh starts with an in-person examination, X-rays where needed and a gum check, and a dentist supervises your teeth until treatment ends. Invisalign is from £3,000 with refinements and Vivera retainers included, while at-home aligners usually cost less but rely on remote checks.
What's the Real Difference Between the Two?
Both use clear plastic aligners, changed every week or two, to move teeth in small steps. The difference is in everything around the aligners.
With Invisalign at a dental practice, a dentist examines you in person before treatment, checks your gums and the bone around your teeth, takes X-rays where needed, plans the tooth movements, fits attachments, sees you regularly during treatment and adjusts the plan when teeth don't move as expected.
With at-home aligners, you typically take your own impressions with a home kit, or have a scan at a shop or partner clinic. A dentist or orthodontist usually reviews your records remotely and approves a plan, and progress is monitored through photos you send in.
Remote review by a qualified clinician is better than none. But a scan or photo is not an examination, and a plan approved without seeing your gums, your bone levels or the roots of your teeth is built on incomplete information.
At Comely Bank Dental in Edinburgh, every Invisalign patient is examined in person before any aligner is ordered.
Why Should a Dentist Examine You Before Teeth Move?
Straightening is the last step, not the first. Before teeth move, the mouth needs to be healthy, and some problems can't be spotted from a photo or impression. At an in-person examination, a dentist checks for:
- decay, including between teeth and under old fillings, which should be treated before aligners cover the teeth for 22 hours a day
- gum disease, measured by gently probing the gaps between gums and teeth
- loose teeth or teeth with reduced support
- crowns, bridges and implants. An implant is fixed in the bone and won't move, and a plan that tries to move it will fail.
- your bite and jaw joints, including clicking, pain or limited opening
- worn, cracked or heavily filled teeth that may need attention first
- soft tissue changes, as part of routine checks for oral cancer
Many of these cause no symptoms at all. That's exactly why they're missed when no one looks.
Have a Proper Check First

What Do X-Rays and Gum Checks Add to a Scan?
A 3D scan or impression shows the crowns of your teeth: the parts above the gum. It doesn't show what's going on underneath, which is where teeth actually move.
X-rays show the roots and the bone around them. They can reveal short roots, roots that have already been shortened by earlier orthodontics, infection at the tip of a root, decay hidden between teeth, cysts and teeth that are fused to the bone and can't move.
Gum checks measure the pockets between gum and tooth. Deep pockets mean active gum disease, and moving teeth while the disease is active can speed up bone loss. If your gums need treatment first, our hygiene team can get them healthy and stable before you start.
Not everyone needs X-rays before aligners, and your dentist will decide what's appropriate for you. But the decision should be made by someone who has examined you.
How Is Invisalign Supervised Once Treatment Starts?
At Comely Bank Dental, you'll see Dr Wardell regularly through treatment, typically every six to ten weeks, with aligners issued in batches between visits. At those appointments we:
- check each tooth is following the plan, rather than lagging behind
- look at your gums and the fit of the aligners
- fit or replace attachments, the small tooth-coloured bumps that help aligners grip
- carry out any planned reshaping between teeth, which creates small amounts of space
- adjust the plan early if something isn't working
Problems found early are usually simple to correct. A tooth that has stopped moving at week six is easier to bring back on track than one discovered at the end.
What Happens If Teeth Don't Follow the Plan?
Teeth don't always move exactly as the computer predicts. Bone density, root shape, how many hours you wear the aligners and how well they fit all play a part. When this happens, a new scan is taken and a further set of aligners, called refinements, is made to finish the job.
Refinements are a normal part of Invisalign. Most people need at least one round, and some need more. At Comely Bank Dental, refinements and Vivera retainers are included in your Invisalign treatment, so a few extra aligners don't bring an unexpected bill.
With at-home aligners, it's worth checking how refinements work, whether they're included, and whether anyone will see you in person if progress stalls.
What Can Go Wrong Without Supervision?
Most people who use aligners don't run into serious problems. But when something does go wrong without anyone checking in person, it can go unnoticed until it's harder to fix. The risks include:
- Bone and gum loss. Moving teeth in gums affected by active gum disease can worsen bone loss and loosen teeth.
- Gum recession. Pushing teeth outwards beyond the bone that supports them can leave the roots exposed.
- Bite problems. Teeth can line up neatly from the front but meet badly at the back, leading to a bite that feels wrong, chipped teeth or jaw discomfort.
- Root shortening. Some shortening of roots can happen with any orthodontic treatment, and is more likely with heavy or poorly planned movements.
- Untreated decay or infection progressing under aligners.
- Relapse. Without the right retainers worn for long enough, teeth drift back.
Some of these changes, such as bone loss and root shortening, can't be reversed. That's the strongest argument for an examination before you start.
Do at-Home Aligners Ever Make Sense?
To be fair to them, at-home aligners usually cost less, and fewer appointments suits some people. For a narrow group of adults with healthy gums, a recent clean bill of health from their dentist and a minor cosmetic concern, such as slight crowding of the lower front teeth, the result can be acceptable.
The difficulty is knowing whether you're in that group. Many people who order at home haven't had a recent examination and X-rays, and don't know their gum health. If you're considering this route, at least have a dental examination first, tell your dentist what you're planning, and carry on with regular dental examinations throughout.
If you've already finished at-home treatment and your bite feels uneven, or you've noticed gum or tooth changes, book an examination. We offer a second opinion for exactly this.
What Should You Ask Any Aligner Provider?
Whether you're comparing practices in Edinburgh or looking at a mail-order kit, these questions are worth asking before you pay:
- Will a dentist examine me in person before treatment? Not just look at a scan or photographs.
- Will my gums be checked, and will I have X-rays if they're needed?
- Who is the clinician responsible? Ask for their name and GDC number, and check the online GDC register.
- Can I see the planned movements before I commit?
- How often will I be seen, and by whom?
- What happens if my teeth don't move as planned? Are refinements included, and how many?
- Are retainers included? How many sets, and what do replacements cost?
- Who do I see if I have a problem mid-treatment? A loose attachment, a broken aligner, a sore tooth.
Clear, confident answers to all of these are a good sign, whichever route you take.
How Does Invisalign Work at Comely Bank Dental?
Your free Invisalign consultation at our Comely Bank practice, near Stockbridge, starts with an examination of your teeth, gums and bite. If X-rays are needed, we'll explain why. We then take a 3D scan with our iTero scanner, which lets us show you a simulation of how your teeth could move, on screen, at the same visit.
Dr Jonathan Wardell has been an Invisalign Diamond Apex Provider every year from 2022 to 2026, which places him in the top 1% of Invisalign providers in Europe. If aligners aren't the right choice for you, he'll tell you, and refer you if fixed braces would serve you better.
Invisalign is from £3,000, with refinements and Vivera retainers included. Your fee is confirmed in a written treatment plan before anything starts. You can see our guide prices on the fees page.
