Clear aligners are sold as a product, which is the source of most of the confusion. The trays are the same wherever you buy them. What you are actually paying for is the treatment plan behind them, and that varies more between clinics than almost anything else in dentistry.
Two people can start the same case on the same system and finish in very different places. Here is what accounts for the difference.
Who plans the case matters more than who sells it
Aligner systems are open to general dentists who complete the provider certification, as well as to orthodontists who spent additional years training specifically in moving teeth. Both can treat straightforward cases well. The gap shows up on the harder ones: bite problems, rotations, cases where teeth need to move in more than one plane.
So ask who writes your plan, in those words. Not who hands you the trays, not whose name is on the door. Who decides, tooth by tooth, what moves and in which order.
Provider tier tells you volume, not skill
Most aligner manufacturers publish a tier for each provider, based on how many cases they have submitted. It is worth asking for, but read it correctly: it is a count, not a quality rating. A high tier means the practitioner has planned a lot of cases and has seen a lot of things go slightly wrong, which is genuinely useful. It does not mean yours will be planned by the person with the tier.
- How many aligner cases this practitioner has personally completed
- Their current provider tier with the manufacturer
- Whether your case will be planned by that same person

Find out how often you will be seen in a chair
Remote monitoring by app is now normal and it saves a lot of pointless trips. It is also, for some clinics, a way to reduce chair time to almost nothing. The two look identical in a brochure.
Ask for the number of in-person appointments the plan assumes. Attachments come loose, teeth do not always track the way the software predicted, and somebody has to look at your mouth rather than at a photograph of it. A plan with a realistic number of reviews built in is a plan written by someone expecting to adjust it.
Refinements are where plans meet reality
A refinement is an extra set of trays, made after the first series, to finish movements that did not complete. They are common. They are not a sign that anything went wrong. What matters is how many are included before they become an additional cost.
Get the number in writing. A clinic that includes a generous allowance is telling you it expects to see the case through; one that includes none is leaving the risk with you.
Retainers are not an afterthought
Teeth move back. That is not a failure of the treatment, it is what teeth do, and retention is part of the treatment rather than an accessory to it. The question is whether retainers and the review appointments that go with them are in the price you were quoted, or billed at the end when you have no leverage left.
Ask what retention costs, and for how many years, before you agree to anything. It is the single most common line to appear after the fact.
What a good answer sounds like
You are looking for specificity and for writing. A practitioner who says their orthodontist plans every case, gives you a personal case count, tells you how many times you will be seen, names a refinement allowance and puts retention in the quote has answered all five questions in about two minutes. One who gives you a brochure has answered none of them.
None of this requires you to understand orthodontics. It requires you to ask five questions and notice whether the answers are concrete. If you would rather not do that part at all, that is what we are for: we ask them first, in writing, and introduce you to a clinic whose answers hold up.
