What happens at an aligner consultation, and what decides whether I'm suitable?

Health comes before alignment

Aligners move teeth through the bone that holds them, and the bone and gum around each tooth have to be healthy enough to tolerate that. Gum disease (periodontitis) damages the tissue and bone that support teeth, so active gum disease is usually treated and brought under control before any tooth movement is planned. Untreated decay, a cracked tooth or a failing filling are also dealt with first, partly because decay that is left alone keeps progressing and partly because a tooth repaired after the scan may no longer match the aligners made from it.

For that reason the consultation usually begins as a thorough check-up of teeth and gums, with X-rays if they are due for you, rather than as a discussion of trays.

What is examined and recorded

• Teeth and gums. Each tooth is checked for decay, wear, cracks and the state of existing fillings and crowns. Gums are checked for inflammation, bleeding, recession and pocket depth, since gum health decides whether moving teeth is sensible yet.
• X-rays. These are taken based on your individual need rather than a fixed schedule. They show root length and shape, bone levels and anything hidden between or below the teeth. Roots matter because orthodontic forces act on them, and bone levels show how much support each tooth has.
• The bite. How the upper and lower teeth meet when you close, slide sideways and chew: overbite, underbite, crossbite, open bite, and whether the back teeth meet evenly on both sides.
• Crowding and spacing. How much room is lacking or left over in each arch. This shapes the plan, because space has to come from somewhere: from widening the arch, from moving teeth back, from polishing a very thin layer of enamel off the sides of some teeth (interproximal reduction), or, in very crowded mouths, from removing a tooth.
• The jaw relationship. Whether the misalignment lies mainly in the teeth or mainly in the size and position of the jaws. Aligners move teeth; on their own they do not change the size or position of the jaws. A mismatch between the jaws may call for other appliances, a specialist, or in rare cases jaw surgery.
• Jaw joints and muscles. Clicking, pain, limited opening or tenderness are noted and discussed on their own terms. Orthodontic treatment is not a recommended way to treat jaw joint disorders (TMD), so aligners should not be presented as a treatment for jaw pain.
• Habits. Grinding or clenching can wear and damage teeth and strain jaw muscles, and it may shorten how long aligners and retainers last. Thumb-sucking, tongue thrusting and pacifier use in childhood are recognized contributors to how teeth end up sitting. Your dentist may also ask about other oral habits so that the plan, and the retainers after it, suit how you actually use your mouth.
• A scan, photographs and a record of your goals. A digital scan or impressions produce a 3D model of your teeth, which becomes the basis of the plan and of the aligners themselves. Photographs record where you are starting from. Just as important is a clear statement from you of what bothers you: a single twisted tooth, a gap, a crowded lower front, a bite that feels off, or teeth that look tipped in a smile.

What aligners do well and what they do less well

Clear aligners are removable, nearly transparent plastic trays, each slightly different from the last, that move teeth in small planned steps. Like braces, they straighten teeth and correct some bite problems, and because they come out, brushing and cleaning between teeth is simpler than around fixed brackets and wires. They suit many cases of mild to moderate crowding and spacing and some bite problems.

They are not the right tool for everything. Aligners work only while they are in the mouth, so they depend completely on the wearer. Some problems, especially those rooted in jaw size or position rather than tooth position, need treatment beyond what trays can do, and more complex alignment problems may still be handled best with braces. Which individual movements are predictable with aligners is a technical judgment the dentist makes from your scan, so it is fair to ask which of the changes you want are considered straightforward and which are demanding. If part of your case falls outside what aligners do predictably, ask whether the office works with an orthodontist and refers cases that need braces or jaw treatment; a clear answer on this point is part of a thorough consultation.

Wear time, attachments, refinements and retainers

• Wear time. Because aligners move nothing while they sit in a case, they are worn for most of the day and night and removed for eating, for drinking anything other than water, and for cleaning. Your dentist will state the daily hours expected and how often you change to the next tray. If you know you would not keep trays in, say so at the consultation; that honesty may point you toward braces instead.
• Attachments and elastics. Some plans use small tooth-colored bumps bonded temporarily to certain teeth so the trays can grip and steer them, and some use elastics hooked between the arches. Ask whether your plan needs them, where they would sit, and how visible they are.
• Check visits. Teeth are checked periodically to confirm they are following the plan, and new trays are issued.
• Refinements. Teeth do not always track exactly as the digital plan predicts, and an extra series of aligners made from a new scan is a common part of treatment rather than a failure. Ask whether refinements are included in the plan you are quoted, and how many.
• Retainers. Teeth tend to drift back after any orthodontic treatment, so retainers are part of the treatment, not an optional extra. Retainers may be removable or fixed (a thin wire bonded behind the front teeth), sometimes combined. Plan on wearing retainers for the long term as directed, and expect removable ones to need replacement over time. Ask what the retainer plan is and what it includes.

Realistic timelines

How long treatment takes depends on how far teeth need to move, how many hours a day the trays are worn, how closely the teeth follow the plan, and whether refinements are needed. Small changes to a few front teeth can take a matter of months; correcting a bite takes considerably longer. Any figure given at a consultation is an estimate from the digital plan, not a promise, and it assumes full wear. If an estimate sounds much shorter than another office's for the same teeth, ask what is being moved and what is being left alone.

What the consultation should leave you with

• A clear verdict on whether aligners are a reasonable tool for the changes you want, and if not, what is.
• The health work that comes first, such as treating gum inflammation or decay, and roughly how it fits into the sequence.
• The plan in outline: which teeth move, whether attachments or elastics are expected, how many trays and visits are anticipated, and how refinements are handled.
• The retainer plan for after active treatment.
• A written estimate that lists what is included (scans, trays, attachments, refinements, retainers, visits) so that you can compare it fairly with another opinion. Our guide on how to compare dental treatment quotes explains how to line two plans up item by item.

Aligners can be requested by a patient, but they are prescribed by a dentist after an examination. The examination is what determines whether they fit your mouth, your bite and your habits.
