1. What Invisalign is and how it works
Invisalign is a brand of clear aligner orthodontic treatment manufactured by Align Technology, delivered through licensed dental providers (general dentists and orthodontists). Each patient receives a series of custom-made transparent plastic aligners that progressively move teeth from their starting position to the target final position.
The treatment sequence is planned digitally by the provider using Align’s ClinCheck software. 3D scans of the patient’s teeth are used to design each aligner in the series, typically involving 20-50 aligners per treatment depending on complexity. Each aligner is worn for 1-2 weeks before advancing to the next. Progress visits every 6-10 weeks verify tracking and make adjustments.
The aligners themselves are made from SmartTrack, Align’s proprietary multilayer plastic, which applies more controlled orthodontic force than generic thermoplastic materials. Small tooth-colored attachments (bumps) are bonded to specific teeth to create grip points for complex movements that flat aligners alone can’t accomplish.
See our canonical treatment page: Invisalign in Gilbert, with parallel pages for Mesa and Glendale.
2. What clear aligners can and can’t correct
Invisalign handles a wider range of cases than it did 10 years ago. What’s treatable today:
- Mild-to-moderate crowding
- Spacing and gaps
- Overbite (upper front teeth covering more than half of lower front teeth)
- Underbite (lower front teeth in front of upper)
- Crossbite (upper and lower teeth misaligned laterally)
- Open bite (front teeth don’t contact when back teeth are together)
- Relapse after prior orthodontic treatment
- Rotations and tipping corrections
- Intrusion (shortening of over-erupted teeth) and extrusion (lengthening of short teeth)
What clear aligners struggle with or can’t handle:
- Severe skeletal discrepancies (jaw size/position imbalances) — these need orthognathic surgery plus orthodontics, not aligners alone
- Very severe crowding requiring significant extractions and complex space closure
- Some canine cases with severe displacement
- Cases where the patient cannot or will not wear aligners 22 hours per day
If we evaluate a case and determine Invisalign isn’t the right approach, we say so. We refer to orthodontists for surgical orthodontics or for cases that genuinely need fixed appliances.
3. Invisalign vs traditional braces — the real tradeoffs
Where Invisalign wins
- Aesthetics. Nearly invisible during wear. For adults who’d be self-conscious about braces at work or in professional settings, this matters substantially.
- Oral hygiene. Aligners come out for brushing and flossing. Patients with good habits maintain better gum health through Invisalign treatment than through braces.
- Dietary freedom. No restrictions on what you can eat — because aligners come out for meals. Traditional braces prohibit popcorn, hard candy, sticky foods, and a long list of other items.
- Comfort. No wires or brackets to poke cheeks or tongue. Mild pressure in the first 2-3 days of each new aligner, then normal.
- Fewer emergency visits. No wire pokes or bracket debondings to schedule around.
Where traditional braces still win
- Most severe cases. Complex skeletal issues, severe crowding requiring extractions, and specific tooth movement patterns are still best handled by fixed appliances.
- Compliance-independent. Braces work 24/7 whether the patient is motivated or not. Invisalign only works if the patient wears the aligners 22 hours per day.
- Slightly faster for some cases. In certain complex scenarios, well-executed braces can achieve faster correction than aligners.
- Lower cost in some markets. Though the gap has closed substantially.
For the majority of common orthodontic cases (mild-to-moderate crowding, spacing, bite correction) in adult patients, Invisalign is our recommended approach. For pediatric cases requiring significant growth modification, traditional braces or specific appliances often remain superior.
4. Invisalign vs mail-order alternatives
SmileDirectClub (now defunct), Byte, Candid, and similar direct-to-consumer aligner companies ship aligners to patients after self-taken impressions or in-store scans, with remote oversight from a licensed dentist or orthodontist the patient never meets in person. Cost is typically half of provider-delivered Invisalign.
The mail-order model fails for predictable reasons:
No clinical exam. Active gum disease, cavities, cracked teeth, and compromised roots aren’t detected. Applying orthodontic force to diseased teeth accelerates damage.
Incomplete treatment planning. Most at-home programs correct only visible front-tooth alignment, ignoring the underlying bite. Patients finish with cosmetically straighter front teeth and a worse bite than they started with — which can cause jaw pain, premature tooth wear, and relapse.
No attachments, no IPR. Mail-order programs can’t bond attachments to your teeth or perform interproximal reduction. Complex movements that require these interventions either under-correct or fail.
No monitoring. When treatment goes off-track, there’s no clinical oversight to catch it. By the time the patient realizes something’s wrong, compensations have built up.
The narrow slice of cases where mail-order aligners work acceptably: very mild cosmetic crowding or spacing on front teeth only, healthy gums and teeth, patient understands results will be cosmetic-level. Outside that slice — which is most cases — see a provider in person.

5. The full treatment process
- Free consultation. Clinical exam, photos, and honest conversation about whether you’re a candidate and what the realistic outcome will be.
- 3D scan and records. Digital scan of both arches with an intraoral scanner (no goopy impressions). Bite registration, panoramic X-ray, additional radiographs as clinically needed.
- Treatment planning. ClinCheck software simulation is reviewed and adjusted by your dentist. You see the predicted outcome in 3D before aligners are ordered.
- Aligner delivery + attachments. 2-3 weeks after records. Attachments bonded to specific teeth. First aligner fitted, wear schedule reviewed.
- Progress visits. Every 6-10 weeks. Tracking check, next set of aligners, attachment adjustments as needed.
- Refinements. Most cases need 1-2 refinement phases after the primary aligners — additional aligners to finalize specific details. Included in treatment cost at Glisten Dental.
- Retention. Custom clear retainers upon completion. Nightly wear indefinitely.
6. Attachments, IPR, and the techniques that make it work
Attachments are small tooth-colored composite bumps bonded to specific teeth, serving as grip points for the aligners. They allow movements that flat aligner plastic alone can’t achieve — rotations of round teeth (canines, premolars), extrusions of short teeth, and precise movements of isolated teeth without affecting neighbors. Most Invisalign treatments involve 6-15 attachments.
IPR (interproximal reduction) is the careful removal of tiny amounts of enamel from between specific teeth — typically 0.25-0.5mm per contact — to create space for tooth movement without extractions. When done within evidence-based limits, IPR is harmless to the teeth involved. It’s an essential technique for treating moderate crowding without removing permanent teeth.
These techniques are why professional Invisalign outperforms mail-order aligners: the clinical oversight to place attachments correctly, perform IPR when indicated, and adjust the treatment as it progresses.
7. Treatment timeline expectations
Typical Invisalign treatment duration at Glisten Dental:
- Simple cases (mild cosmetic correction): 6-9 months, 15-25 aligners
- Moderate cases (moderate crowding or spacing, mild bite issues): 9-15 months, 25-40 aligners
- Complex cases (bite correction, moderate-to-severe crowding, multi-tooth movements): 15-24 months, 40-60 aligners plus 1-2 refinement phases
- Invisalign Express / Lite (minor cosmetic cases): 3-6 months, 7-14 aligners
Patients with excellent compliance (22+ hours daily wear, changing aligners on schedule) often finish slightly ahead of these estimates. Patients who skip wear or change aligners late extend treatment.
8. Costs and what drives them
Invisalign at Glisten Dental Studio in Gilbert: $3,800-$6,500 depending on case complexity. The range reflects real differences — simpler cases on the lower end, complex cases with multiple refinements on the upper end.
Cost drivers:
- Case complexity (Invisalign Express/Lite is less than Comprehensive)
- Number of aligners required
- Whether multiple refinement phases are needed
- Retainer costs (sometimes included, sometimes separate)
- Whether attachments and IPR are required (almost always are, but covered in the quoted cost)
Avoid “bargain” Invisalign quotes substantially below market. Corners typically get cut on: treatment planning depth, number of refinements included (patients charged extra for work that should have been included), retainer support, or follow-through on relapse/complications.
9. Insurance and financing
Most dental insurance plans with orthodontic benefits cover Invisalign at the same rate as traditional braces. Typical coverage: 50% up to a lifetime orthodontic maximum of $1,500-$2,500 per person. This is a lifetime benefit, not annual — it doesn’t reset.
For active duty military dependents, TRICARE Dental covers orthodontics at 50% up to $1,750 lifetime maximum — see our TRICARE guide for details.
Flexible spending accounts (FSA) and health savings accounts (HSA) can be used for Invisalign as a qualified medical expense. CareCredit and in-office financing spread remaining costs across 18-24 months, typically at 0% promotional interest rates.
10. Wearing the aligners — the 22-hour rule
Invisalign requires 22 hours of daily wear. This is not negotiable — it’s the threshold where tooth movement happens reliably. Patients who wear aligners 18-20 hours daily get substantially slower movement, more tracking issues, and longer overall treatment time.
Practical rules:
- Remove for meals only. Put them back in immediately after eating.
- Remove for anything with sugar or color (coffee, tea, wine, soda) — these stain the aligners and concentrate sugar against your teeth.
- Plain water is fine while wearing aligners. No other drinks.
- Brush teeth before putting aligners back in after meals. Food trapped under aligners causes rapid decay.
- Keep aligners in a case when out — wrapping them in a napkin at restaurants is the #1 cause of lost aligners.
The math: 22 hours of wear means 2 hours of non-wear per day. For most patients, that’s 90 minutes total for three meals plus 30 minutes of buffer for snacks, coffee, etc. Realistic but requires intention.
11. Retention — the part that’s skipped most often
Every tooth that’s moved orthodontically wants to return to its starting position. Retention is what prevents relapse. Without nightly retainer wear, teeth shift back partially or fully over 1-5 years.
Our protocol at Glisten Dental: custom clear retainers at completion, worn every night indefinitely. New retainers every 2-3 years as they wear out. Patients who stop wearing retainers after a year or two are the ones who come back for Invisalign “refresh” treatments 5-8 years later.
Retention is not expensive, not difficult, and produces lifelong results. Skipping it is the single biggest cause of wasted orthodontic investment we see.
12. Invisalign for teens
Invisalign Teen is a specific product designed for adolescent patients with compliance indicators (blue dots that fade with wear to track usage) and eruption tabs that accommodate teeth still coming in. Works well for motivated teens with appropriate cases.
Teen compliance is the variable. We screen in consultation — asking the teen directly (not just the parent) about their motivation, understanding of the 22-hour requirement, and willingness to commit. Teens who aren’t motivated will underwear aligners and produce suboptimal results. For that subset of cases, traditional braces are often better because compliance is removed from the equation.
13. Frequently asked questions
Will my teeth hurt during treatment? Mild pressure and tenderness for 2-3 days after each new aligner. Over-the-counter ibuprofen manages this. Patients who describe Invisalign as “painful” are unusual; most describe it as occasionally uncomfortable.
Can I eat with aligners in? No. They’d break, stain, or trap food against your teeth causing decay. Remove for all meals, eating, and drinks other than plain water.
How often do I change aligners? Typically every 1-2 weeks depending on the treatment plan. Some cases use weekly changes with proper fit; others need 2-week intervals.
What if I lose an aligner? Call us. Usually we advance to the next in the series; sometimes we order a replacement of the missing one. Don’t skip ahead without clinical guidance.
How is Invisalign cleaned? Rinse in cold water after eating. Brush gently with a soft toothbrush and clear liquid soap (not toothpaste — it’s abrasive). Soak in denture cleaner or Invisalign cleaning crystals weekly. Never use hot water (warps the plastic).
Can I have Invisalign if I have crowns, bridges, or implants? Crowns yes. Bridges — depends on case; sometimes implants attached to the bridge limit what can be moved. Implants can’t be moved but surrounding natural teeth can be moved around them. Planning accommodates these situations.
Will Invisalign work if I need a tooth extracted? Sometimes yes, sometimes no. Moderate cases with extractions can be treated with Invisalign (it’s more complex); severe extraction cases typically need braces for the space closure. Consultation determines which.
How long before I see results? Most patients see noticeable changes within 6-8 weeks. Full results at treatment completion. Subtle cosmetic improvements happen throughout.
Can I whiten my teeth during Invisalign? Generally wait until after completion. Whitening works better on teeth in final position, and whitening products can interact with aligner plastic. Post-treatment whitening with your retainers as delivery trays works beautifully.
