Invisalign® is the world’s most widely used clear aligner system, with millions of patients treated globally since its introduction in 1999. Using a series of custom-fabricated, BPA-free clear plastic aligners, Invisalign® moves teeth gradually toward their target positions through a carefully staged sequence of planned movements. The aligners are virtually invisible, removable, and more comfortable than traditional metal braces, making Invisalign® one of the most popular orthodontic treatment options for teenagers and adults seeking a discreet path to a straighter smile.
Treatment begins with a comprehensive orthodontic evaluation including photographs, dental X-rays, and a digital scan of the teeth. The scan data is used to create a ClinCheck® digital treatment plan—a computer simulation of the proposed tooth movement sequence from the initial position to the final target. Patients can review this simulation before treatment begins, giving them a preview of the expected result. Once the plan is approved, Invisalign® fabricates a custom series of aligners. Each aligner is worn for approximately one to two weeks, and progress is monitored at regular check-up appointments.
Invisalign® aligners are made from patented SmartTrack® material, which fits snugly over the teeth and applies gentle, controlled forces to move them predictably. The system includes SmartForce® attachments—small, tooth-colored bumps bonded to specific teeth to facilitate more complex movements that aligners alone cannot achieve. These attachments are removed when treatment is complete and do not damage the teeth.
Invisalign® has expanded its clinical capabilities significantly over the years and can now address a wide range of orthodontic conditions including mild to severe crowding, spacing, open bite, overbite, underbite, and crossbite. With appropriate clinical planning and the use of attachments and other auxiliaries, Invisalign® achieves outcomes that approach those of traditional braces for most adult and teenage patients. For highly complex cases, traditional fixed appliances may still be preferable, and we discuss all options honestly at the consultation.
The removability of Invisalign® aligners is one of their most appreciated features. Patients remove them for eating and drinking (except plain water), allowing a completely unrestricted diet. Brushing and flossing are done normally, making oral hygiene during treatment simpler than with braces. Social and professional life is unaffected, as the aligners are virtually undetectable when worn.

Invisalign® works by applying gentle, controlled pressure to the teeth through a series of custom-made clear aligners. Each aligner is slightly different from the previous one, moving specific teeth by small, incremental amounts. Wearing each aligner for the prescribed period allows the bone and soft tissue to remodel around the moved teeth before the next aligner applies further movement. The cumulative effect of the series moves the teeth from their starting positions to their planned final positions.
Before the aligners are made, a digital treatment plan (ClinCheck®) is created showing each stage of tooth movement. This plan is reviewed and approved before fabrication begins. Attachments—small tooth-colored bumps bonded to specific teeth—may be added to facilitate movements that require more precise force vectors than the aligner alone can provide.
Treatment duration varies based on the complexity of the case. Mild cases may be completed in six to twelve months. Average complexity cases typically take 12 to 18 months. More involved cases can take 18 to 24 months or longer. The ClinCheck® digital plan provides an estimate of the number of aligners and the overall treatment timeline before treatment begins.
The single most important factor in staying on schedule is wearing the aligners for the recommended 20 to 22 hours per day. Patients who consistently comply with wear time progress as planned. Those who remove aligners for significantly longer than recommended will extend their treatment timeline, as the planned tooth movements are based on consistent aligner pressure.
For most orthodontic conditions—including mild to moderate crowding, spacing, and common bite discrepancies—Invisalign® achieves results comparable to traditional braces in the hands of an experienced provider. The system has evolved significantly since its introduction and now includes features such as SmartForce® attachments, precision bite ramps, and optimized staging algorithms that have substantially expanded its clinical capabilities.
For some complex cases—including significant vertical corrections, severe crowding requiring extraction, or intricate tooth movements—traditional fixed appliances may still offer advantages. We evaluate each patient’s case honestly and recommend the approach that will provide the best clinical outcome for their specific situation, not the most convenient one.
The cost of Invisalign® varies based on the complexity and scope of the case, the geographic area, and the provider’s fee structure. Comprehensive Invisalign® treatment typically falls in a range comparable to traditional braces for most cases. Invisalign® Lite—a limited case option for minor corrections—is typically less expensive. A specific cost estimate is provided after the initial evaluation, when the scope of treatment is understood.
Many dental insurance plans include orthodontic coverage that can be applied to Invisalign® treatment. FSA and HSA funds can also be used. Financing options with monthly payment plans are available. We discuss all cost and payment options at the consultation so you can make an informed decision.
Most patients experience mild pressure or temporary soreness for one to three days when switching to each new aligner. This discomfort is normal and indicates that tooth movement is occurring as planned. It typically resolves within a few days and is managed easily with over-the-counter pain relievers if needed. Most patients find the discomfort much more manageable than they expected.
Invisalign® aligners do not cause the bracket and wire irritation associated with traditional braces. There are no wires to poke the cheeks, no brackets to come loose, and no wire adjustment appointments that can cause temporary soreness. Overall, the majority of patients find Invisalign® significantly more comfortable throughout treatment than conventional braces.
Because Invisalign® aligners are removable, there are no dietary restrictions during treatment. Simply remove the aligners before eating or drinking anything other than plain water, enjoy your meal normally, rinse or brush your teeth, and replace the aligners. This freedom to eat without restriction is one of the most appreciated practical advantages of aligner treatment over braces, which prohibit sticky, hard, and chewy foods throughout treatment.
The practical discipline required is to actually remove the aligners before eating and to clean the teeth before replacing them. Patients who eat or drink with aligners in risk staining the trays, trapping food beneath them, and potentially damaging them. The habit of removing, eating, brushing, and replacing becomes second nature quickly for most patients.
Invisalign® progress appointments are typically scheduled every six to ten weeks, though the specific interval depends on the stage of treatment and the complexity of the case. At these appointments, we assess tooth movement, ensure the current aligner is fitting correctly, check for any issues with attachments, and provide the next series of aligners. X-rays are taken periodically to monitor root health and bone response.
Unlike braces, which require monthly wire adjustment appointments, Invisalign®’s less frequent appointment schedule is convenient for patients with busy schedules. Between appointments, patients manage their own progress by switching aligners on schedule and wearing them for the recommended time each day.
After the active aligner series is complete, retainers are required to maintain the achieved results. Teeth have a natural tendency to drift back toward their pre-treatment positions (relapse), and retainers prevent this from happening. Custom clear retainers similar in appearance to Invisalign® aligners are the most common retention option. Fixed (bonded) retainers attached behind the front teeth are another option, particularly for the lower front teeth.
Initially, retainers are worn most of the time and are gradually transitioned to nighttime wear only as stability is confirmed. Long-term nightly retainer wear is the standard recommendation for maintaining orthodontic results indefinitely. Stopping retainer wear allows the teeth to shift, potentially requiring retreatment.
Yes—Invisalign® is commonly used for patients who had orthodontic treatment earlier in life and have experienced relapse (shifting of teeth after braces were removed, usually due to inconsistent retainer wear). These cases often involve more limited movement than original orthodontic treatment and may be suitable for Invisalign® Lite or a shorter comprehensive series depending on the degree of relapse.
Evaluation of the current tooth positions and any prior orthodontic records helps determine the scope of movement needed. Patients with prior orthodontic treatment who have relapsed can often achieve excellent results with a second round of aligner treatment.
At Cameron Park Dental Care, we take Invisalign® treatment seriously—providing thorough evaluations, careful ClinCheck® review and customization, attentive monitoring throughout treatment, and clear guidance on compliance and home care. Our goal is not just to complete an aligner series but to achieve a result that genuinely improves the alignment, function, and appearance of your smile.
