Invisalign

Invisalign® is a form of orthodontic treatment that works to correct many different types of malocclusions through the use of a series of clear plastic trays called aligners. As a more discreet, comfortable and completely removable method of care, Invisalign aligners provide an effective alternative to traditional orthodontic braces and metal wires for certain types of malocclusions.

Developed by a team of Stanford University students, the advanced 3D imaging, modeling, and aligner technology that defines the Invisalign system of care was introduced to the public in the year 2000. Since that time, it has become an extremely popular option in care.

Invisalign uses advanced 3-D computer imaging technology to formulate a sequence of custom-made clear aligners. The aligners, each of which is worn for a couple of weeks, incrementally move the teeth into place until the final desired corrections are reached. The advantage and appeal of the Invisalign method are that the clear aligners are more cosmetic, comfortable and convenient than other orthodontic appliances and operate with minimal interference to daily activities. Invisalign allows teens and adults to enjoy eating all of their favorite foods, and engage in sports without the fear of breaking their orthodontic appliances or sharp poking wires. Moreover, as the aligners are completely removable, tooth brushing and flossing are much easier as there is no need to clean in between any attached orthodontic brackets or wires.

Frequently Asked Questions

What is Invisalign® and how does it straighten teeth?

+

Invisalign® is a modern orthodontic system that uses clear, removable aligners to straighten teeth discreetly. Each set of aligners is custom-made from smooth, BPA-free plastic to fit snugly and guide teeth into position. Because the trays are nearly invisible, many patients prefer Invisalign over visible metal brackets for a more discreet treatment option.

Treatment is planned using advanced digital scanning and 3-D imaging to map tooth movement from the current alignment to the intended result. A sequence of aligners is produced to apply controlled forces so teeth shift incrementally over time. Your dentist reviews and refines the digital plan so the movement sequence matches both functional and cosmetic objectives.

How does the Invisalign® treatment process work from consultation to completion?

+

The Invisalign® process begins with a comprehensive consultation and oral exam to determine candidacy and identify any underlying dental issues that must be addressed first. During this visit your dentist takes digital scans or impressions and evaluates bite relationships, periodontal health and restorative needs. These records form the basis of a personalized treatment plan that outlines the expected tooth movements and timeline.

Once the plan is finalized, a series of custom aligners is fabricated and delivered in phases for you to wear at home. Typically you wear each aligner for about one to two weeks before progressing to the next, following your dentist’s instructions. The team at Stahl Dental Studio monitors progress and makes adjustments as needed to keep treatment on track.

Who is a good candidate for Invisalign®?

+

Many adults and teens with mild to moderate spacing, crowding or bite issues are good candidates for Invisalign®. Because aligners are removable and nearly invisible, they are especially appealing for patients who want a discreet treatment option. However, severe skeletal discrepancies or very complex tooth movements may require traditional braces or a multidisciplinary approach.

An in-person evaluation is necessary to assess root positions, periodontal health and jaw alignment before confirming candidacy. Your dentist will also consider habits, compliance potential and any restorative or surgical needs that could affect the plan. Appropriate oral hygiene and consistent wear of aligners—generally 20 to 22 hours per day—are essential for predictable outcomes.

How long does Invisalign® treatment typically take?

+

Treatment length varies depending on the complexity of the case and patient compliance. Many adults complete active Invisalign® treatment in approximately six to eighteen months, while simpler cases can finish more quickly and more complex cases may require longer care. Your dentist will provide a personalized estimate during the consultation based on the planned movements and clinical findings.

Sticking to the prescribed wear schedule and attending scheduled checkups helps keep treatment on schedule and can reduce unwanted delays. Occasional refinements or additional aligners may be recommended to fine-tune results, and these are integrated into the overall plan as necessary. After active treatment, a retention phase is recommended to stabilize tooth positions and protect the result.

What should I expect in terms of comfort and discomfort with Invisalign®?

+

Most patients experience pressure or mild soreness for a few days after switching to a new set of aligners as teeth respond to the prescribed forces. This sensation is generally temporary and often described as less intense than the discomfort associated with adjustments to fixed braces. The aligners are made from smooth plastic designed to reduce soft-tissue irritation compared with brackets and wires.

If you experience persistent pain, sore spots or problems with fit, contact your dental team so adjustments can be made or a replacement aligner provided. Over-the-counter pain relievers and soft foods can help manage brief periods of discomfort during the initial days of a new tray. Proper fit and careful handling of the trays also minimize breakage and the need for unscheduled visits.

How should I care for my aligners and maintain oral hygiene during treatment?

+

Keeping your aligners and teeth clean is critical for oral health during treatment and for achieving predictable results. Rinse aligners whenever you remove them and brush them gently with a soft toothbrush and clear, mild soap to prevent staining and bacterial buildup. Avoid hot water, which can warp the plastic, and store aligners in their protective case when not in use.

Brush and floss thoroughly after meals before reinserting aligners to reduce the risk of cavities and gum inflammation. Regular dental cleanings and periodontal evaluations remain important throughout treatment to monitor overall oral health. Your dental team will provide specific cleaning products or soaking solutions if recommended for your aligners.

Will Invisalign® require attachments, IPR or elastics during treatment?

+

Some Invisalign® cases use small tooth-colored attachments bonded to teeth to help the aligner apply more precise forces for specific movements. Interproximal reduction (IPR) and clear or elastic auxiliaries may also be used when spaces, rotations or bite corrections require additional control. These adjunctive procedures are routine, minimally invasive and are planned in advance as part of the digital treatment design.

Your dentist will explain any attachments or auxiliary techniques during the case presentation so you know what to expect at placement and during wear. Attachments are discreet and blend with the tooth surface, and they generally do not change your cleaning routine beyond normal care. If auxiliaries such as elastics are required, the office will provide detailed instructions on wear time and handling to achieve the intended results.

How often will I need to visit the dentist during Invisalign® treatment?

+

Invisalign® treatment typically requires periodic in-office visits to monitor progress and receive new aligner sets. Initially visits may be scheduled every four to eight weeks depending on the clinical situation and the practice’s protocol. During these appointments the dentist evaluates fit, checks tooth movement and addresses any concerns or refinements.

Emergency or unscheduled visits are available if an aligner breaks, an attachment loosens, or if you experience significant discomfort that needs attention. The dental team will guide you on how to proceed at home while arranging an appointment so treatment continues with minimal interruption. Good communication and adherence to the visit schedule help ensure predictable progress and timely completion of treatment.

How does Invisalign® compare with traditional braces for adults and teens?

+

Compared with traditional braces, Invisalign® offers clear, removable trays that are less visible and allow easier brushing and eating. Many adults and image-conscious teens appreciate the aesthetic benefit and the ability to maintain normal oral hygiene routines. However, braces still offer certain mechanical advantages for complex tooth movements and severe bite corrections.

The choice between aligners and braces depends on clinical needs, patient preferences and willingness to comply with aligner wear requirements. Your dentist will review the advantages and limitations of each option and recommend the approach that best balances efficiency, predictability and long-term oral health. In some cases, a hybrid approach or combined treatments with fixed appliances may provide the optimal outcome.

What happens after I finish Invisalign® treatment to keep my smile stable?

+

Retention is a critical phase after active Invisalign® treatment to maintain tooth positions and prevent relapse. Most patients wear a retainer full-time for a period determined by their dentist and then transition to nighttime wear to preserve results. Options include removable clear retainers and fixed bonded retainers; your dentist will recommend the appliance that best suits your case.

Periodic follow-up visits help assess the stability of your smile and the condition of any retainers so issues can be addressed early. The team at Stahl Dental Studio provides tailored retention plans and ongoing monitoring to protect the long-term success of your treatment. Maintaining excellent oral hygiene and attending routine dental appointments will help your new smile stay healthy and stable for years to come.
