Can you order aligners online?

Short answer: you can order aligners online, but I do not recommend it without an orthodontic examination and supervision. Before treatment the gums, roots, bone and bite must be checked, and during treatment the real movement of the teeth must be compared with the plan. An aligner is a good tool, but the doctor, not the tool, leads the treatment.

Today you can order almost anything online, even aligners to straighten your teeth. In adverts it looks very simple: you take an impression at home and the aligners arrive by post. But there is a catch: planning tooth movement on a computer is one thing, following how that movement happens in real life is another.

What aligners do well

Aligners are one of the great possibilities of modern orthodontics and I use them too. According to a systematic review they are effective for aligning teeth, for some movements of the front teeth and for moving back teeth over certain distances. They are almost invisible, come out for eating and brushing, and hygiene is easier.

Where they struggle

• Lengthening teeth, that is extrusion
• Rotating round teeth such as canines and premolars
• Precise control of root position
• Large bite corrections

These movements are less predictable with aligners. This does not mean they cannot be done. It means additional tools such as small attachments bonded to the teeth, elastics or mini-screws may be needed, and the plan may have to be revised during treatment.

Comparison with braces

In studies comparing aligners with braces both methods were effective. Braces performed better on some measures, such as control of the bite relationship, tooth angulation and root position. That is why the method has to be chosen for each case separately. A detailed comparison: braces or aligners.

Risks of treatment without an examination

• With active gum disease, moving teeth can speed up bone loss
• Hidden decay can progress faster under an aligner
• The teeth may straighten while the bite gets worse
• When a problem arises, it is unclear who is responsible

Why orthodontic supervision matters

The computer plan shows how the teeth should move, but teeth do not always move at the same speed and in the same direction as planned. At every visit I check how the aligners fit, how the teeth have moved and the condition of the gums. When needed we change attachments, add elastics or order new aligners. Without this supervision a small deviation can build up over months into a big problem.

Who aligners suit

• Those ready to wear aligners for the recommended hours every day
• Teenagers and adults who want invisible treatment
• Cases where tooth movement is predictable with aligners
• Cases with minor relapse after retention

Questions to ask before starting

If you are considering aligner treatment, whichever company or clinic it is, it is important to know the answers to these questions:

1. Will a doctor examine me in person before treatment?
2. Will X-rays and a gum check be done?
3. Who prepares the plan and who approves it?
4. How many check-up visits will I have during treatment?
5. What happens if the teeth do not follow the plan?
6. How will retention work after treatment?

If there are no clear answers, the management of treatment actually falls on you. The aligner itself is not bad, but in unsupervised treatment nobody notices a problem in time.

Impression and scan

Impressions taken at home often do not show the edges of the teeth and gums accurately. An impression or digital scan taken in the clinic is done under the doctor’s supervision, checked immediately and repeated if needed. The accuracy of the plan starts with this first piece of information.

What the science says

• Systematic review (2015): aligners are effective for alignment and some movements, while extrusion and rotation of round teeth are harder to control.
• Comparative review (2019): both methods are effective; braces are better at measures such as the bite relationship and root control.
