Invisalign is worth it only for patients who can commit to wearing the aligners 20 to 22 hours a day; it is the wrong choice for anyone unwilling to make that commitment, since the real drawbacks are a strict wear-time requirement, a limited range for complex bites, and mandatory long-term retention. At Sola Dental Spa in Staten Island, every Invisalign consultation includes an honest assessment of whether your case fits within what clear aligners can predictably treat.
What Invisalign cannot treat well
Invisalign is most reliable for mild to moderate crowding, spacing, and certain bite discrepancies. It consistently underperforms fixed braces on severe skeletal malocclusions such as a significant overbite, underbite, or open bite driven by jaw position, on large vertical tooth movements, and on rotations of round teeth like canines, which are hard to control with a removable tray. Patients with an existing bridge face a specific limit too: an aligner cannot move a bridged unit, so the plan has to work around that fixed segment.
An experienced provider identifies these limits during the consultation and either recommends a different path or explains clearly how far Invisalign can take your case. If a provider claims Invisalign can fix anything braces can fix without qualification, get a second opinion.
The compliance requirement is not flexible
Invisalign aligners must be worn 20 to 22 hours a day for the full course of treatment, removed only for eating, drinking anything other than water, and brushing. Each tray applies a calculated force to move teeth a set distance before the next tray goes in. If a tray is not worn long enough, the tooth does not reach its target, which compounds into inaccuracies that lengthen treatment and often require refinement trays. Before starting, compare your daily routine honestly against that 20 to 22 hour requirement.
Cost is part of the decision too. Invisalign and comprehensive fixed braces are usually priced in a similar range for cases of comparable complexity, so the deciding factor is rarely price alone. It comes down to whether the removable, compliance-dependent format fits your daily life better than a fixed appliance that requires no daily discipline but more diet and hygiene adjustments.
| Factor | Invisalign | Fixed braces |
|---|---|---|
| Visibility | Nearly invisible when worn | Visible brackets and wires |
| Compliance | Removable, requires 20 to 22 hours a day | Fixed, compliance built into the appliance |
| Complex cases | Limited for severe malocclusion and some rotations | Handles a broader range of movements |
| Oral hygiene | Easier, removed for brushing and flossing | More demanding around brackets |
| Diet | No restrictions, remove to eat | Restrictions on hard and sticky foods |
"I tell every Invisalign patient the same thing upfront: the aligner only works when it is in your mouth. For patients who can commit to 20 to 22 hours of daily wear, the results are excellent and the experience is far more comfortable than braces. For patients who know they will take the aligners out whenever something feels inconvenient, traditional braces will serve them better, because compliance is built into the appliance."

Retention is part of the treatment, not optional
After Invisalign finishes, teeth do not stay put on their own. The bone and ligament supporting each tooth keep exerting force toward the original position for months to years, which is true after braces as well. Retainer wear is what preserves the result. Most patients wear a retainer full time for the first six to twelve months, then nightly after that. Patients who stop within the first year commonly see the lower front teeth shift back.
How Sola Dental Spa approaches Invisalign
Dr. Anne Gershkowitz performs Invisalign consultations using a 3D digital scan rather than a traditional impression, which produces a more accurate simulation and a better-fitting first tray. If your case falls outside what Invisalign addresses well, you will hear that directly along with an alternative. For candidates who are a good fit, the compliance requirements are reviewed in detail so the plan is realistic from the start.

Frequently asked questions
Does Invisalign hurt?
Most patients feel pressure or mild aching for the first one to three days after switching to a new tray. It is the normal sensation of teeth beginning to move and is usually milder than the tightening appointments associated with braces.
Will Invisalign affect my speech?
A mild lisp is common for the first one to two weeks as the tongue adapts. Most patients notice no effect by the second or third tray.
How long does Invisalign treatment take?
It depends on case complexity. Minor spacing or crowding can finish in six to nine months, moderate cases typically run twelve to eighteen months, and more involved cases can extend past two years, especially if refinement trays are needed.
Is there a risk of root resorption with Invisalign?
Any orthodontic force carries a small risk of root resorption, a shortening of the tooth root. Research indicates the risk is comparable between Invisalign and fixed braces when treatment is managed by an experienced provider, and significant cases are rare.
What happens if I do not wear my retainer?
Teeth begin drifting back toward their original position, most noticeably in the lower front teeth, often within the first year after treatment ends.
