A Modern Clear Aligner Treatment for Straighter Teeth

Invisalign clear aligners offer a modern, discreet way to straighten your teeth without traditional metal braces. At Merrifield Dental Associates, we provide customized Invisalign treatment for patients throughout Merrifield, Fairfax, Vienna, Annandale, Mantua, and surrounding Northern Virginia. Using a series of virtually invisible aligners, we gradually move your teeth into healthier, more functional positions while helping you achieve a straighter, more confident smile.
These aligners are virtually invisible and removable, allowing you to improve your smile without the inconvenience of traditional braces. In many cases, treatment can be completed in as little as 12 months, depending on your individual needs.
A Clear Alternative to Braces
Unlike traditional braces, Invisalign clear aligners use a series of smooth, comfortable trays with no metal wires or brackets. Patients throughout Merrifield, Fairfax, and surrounding Northern Virginia appreciate the ability to straighten their teeth discreetly while continuing to eat, brush, and floss normally. Invisalign is a popular choice for both teens and adults seeking a convenient, comfortable, and natural-looking orthodontic treatment.
However, traditional braces may still be recommended for more complex orthodontic cases.
How Does Invisalign Work?

Invisalign treatment begins with a digital scan of your teeth using our iTero scanner. The scan creates a detailed 3D model of your teeth that allows us to evaluate your bite, plan tooth movement, and develop a customized treatment plan.
Your Invisalign treatment follows a simple, personalized process designed to create predictable, comfortable results:
- Digital iTero® scan and customized treatment planning
- Custom Invisalign aligners are designed and created specifically for your smile
- Wear your aligners 20–22 hours per day, removing them only to eat, brush, and floss
- Progress visits every 4–8 weeks to monitor your treatment and provide your next sets of aligners
- Custom retainers provided after treatment to help maintain your new smile for years to come
What Can Invisalign Treat?
Invisalign clear aligners can effectively correct many common orthodontic concerns, helping patients achieve a healthier, more confident smile. Treatment may be recommended for:
- Crooked or misaligned teeth
- Gaps between teeth
- Mild to moderate crowding
- Overbite, underbite, and crossbite
- Certain bite (occlusion) problems that may contribute to teeth grinding (bruxism) or excessive wear on the teeth
During your Invisalign consultation at Merrifield Dental Associates, we’ll evaluate your bite, discuss your goals, and determine whether Invisalign is the right treatment for your smile. For more complex orthodontic cases, we’ll recommend the treatment option best suited to your needs.
Benefits of Invisalign

Invisalign offers several advantages over traditional orthodontic treatment, particularly for teens and adults who want to straighten their teeth without significantly changing their appearance or daily routine.
Why are Invisalign aligners less noticeable than braces?
Invisalign aligners are made from clear material and custom-fitted to your teeth, making them much less noticeable than traditional metal brackets and wires. This makes Invisalign especially appealing to adults and teens who want a discreet way to straighten their smile. Invisalign can also be incorporated into a broader cosmetic dentistry treatment plan when patients want to address additional aesthetic concerns.
Can I remove Invisalign to eat, brush, and floss?
Yes. Invisalign aligners are removable, so there are no brackets or wires restricting what you can eat. Simply remove your aligners for meals and brush your teeth before putting them back in. Being able to remove the trays also makes brushing and flossing much easier than with traditional braces.
Is Invisalign comfortable to wear?
Invisalign aligners are made from smooth material and custom-designed to fit closely over your teeth. While you may feel pressure or mild soreness when beginning a new set of aligners, there are no metal brackets or wires that can irritate the cheeks and gums.
How long does Invisalign treatment take?
Treatment time depends on how much tooth movement is required and how consistently you wear your aligners. Many patients complete Invisalign treatment in approximately 6 to 12 months, although simpler cases may take less time and more complex cases can take longer. At Merrifield Dental Associates, we provide a personalized treatment estimate after evaluating your teeth and bite.
How many hours a day should I wear Invisalign?
For Invisalign to work predictably, aligners generally need to be worn approximately 20–22 hours per day. They should usually only be removed for eating, drinking anything other than water, brushing, and flossing.
Will I need retainers after Invisalign?
Yes. Retainers are an important part of maintaining your results after Invisalign treatment. Without retention, teeth can gradually move from their corrected positions over time. Learn more about our Invisalign retainers in Merrifield and Fairfax, VA and how they help prevent orthodontic relapse.
Invisalign vs. Traditional Braces

Both Invisalign and traditional braces can effectively straighten teeth, but the treatment experience is different. Invisalign uses removable clear aligners rather than brackets and wires, making it easier to eat normally, brush and floss, and straighten your teeth discreetly.
Invisalign can be an excellent option for many mild to moderate orthodontic problems, but traditional braces may still be more appropriate for certain complex tooth movements or bite problems. During your consultation, we’ll evaluate your teeth and bite to determine which treatment approach is appropriate for you.
What Happens After Invisalign? Retainers and Long-Term Results

Completing your final Invisalign aligner is an exciting milestone, but maintaining your new tooth positions is an important part of protecting your results. Teeth naturally have a tendency to shift over time, a process known as orthodontic relapse, which is why retainers are recommended after Invisalign treatment.
We use our iTero digital scanner to capture a detailed 3D scan of your finished smile. This allows us to create accurately fitting clear retainers designed to hold your teeth in their new positions and preserve the smile you worked to achieve.

Finishing Your New Smile
Once your Invisalign treatment is complete and your teeth are in their final positions, you may want to further enhance your new smile. Some patients choose professional ZOOM teeth whitening after Invisalign to brighten their teeth and complement their newly straightened smile. Whitening is completely optional and can be discussed once your Invisalign treatment is complete.
