Crooked, crowded, twisted, or gapped teeth have a negative impact on your appearance, chewing function, and oral health.

However, many people who need orthodontics may avoid treatment because they don't want to wear metal braces.

At our Rockville, MD, practice, we use Invisalign® to correct misaligned smiles without the need for conventional orthodontics. 

How Does Invisalign Work?

Created by Align Technology, Inc., Invisalign utilizes a series of clear aligners to gently and effectively straighten teeth. Whether your teeth are crooked, twisted, crowded, or spaced too far apart, Invisalign can help, leaving you with the beautiful smile you've always wanted. We use Invisalign clear aligners to correct crossbites, overbites, underbites, and other common orthodontic issues. In fact, Invisalign aligners can address most of the same issues as braces.
Invisalign is a great option for adults or teenagers who wish to avoid the metal bands and brackets of traditional braces. With individualized treatment plans and extensive preplanning, Dr. Victor Siegel can provide his patients with results that go unmatched by other orthodontic treatments. Clear aligners are changed out every two weeks until the desired tooth movement has been achieved. On average, Invisalign treatment takes 12 to 18 months to complete.

Clear Aligners: No More Brackets and Wires

Clear aligners help patients achieve a perfectly aligned bite without brackets and wires. Instead, Dr. Victor Siegel uses a sequence of plastic trays, attachments, and buttons to correct crowded, overlapping, and gapped teeth. Clean aligner therapy can also alleviate jaw pain caused by dental misalignment.

Do I Have to See an Orthodontist To Find Out If Invisalign Is a Good Fit?

People may think an orthodontist is necessary when it comes to evaluating your candidacy for Invisalign. However, general dentists are trained in Invisalign treatment like orthodontists.

Dr. Siegel has spent nearly four decades practicing cosmetic dentistry and general dentistry. He's helped patients with various oral health issues achieve their goals. Dr. Kramer has completed training for complex aspects of dentistry and can improve any patient's smile.

Invisalign Can Address 

  • Underbites
  • Crossbites
  • Crowded Teeth
  • Crooked Teeth
  • Gapped Teeth
  • Open Bites

Crooked teeth and a misaligned bite can cause health problems like headaches, teeth grinding, joint pain, and trouble sleeping.

Invisalign can treat many of the same orthodontic issues that traditional braces can fix. Patients with severe or complex malocclusion may benefit from a different treatment. If so, the dentists at our Rockville, MD, practice offer a range of orthodontic procedures that can enhance your smile. 

It's Never Too Late to Transform Your Smile Request a Consultation Today

After reaching adulthood, many people would prefer not to spend years wearing uncomfortable metal braces to straighten their teeth. Thanks to Invisalign, adults and teens can undergo discreet orthodontic treatment without the wires and brackets that come with braces.

Our dentists can review your oral health and see if Invisalign matches your long-term goals. To learn more about your treatment options, contact our Rockville, MD, office today or give us a call:

Invisalign Treatment Timeline

Whether you've never had major orthodontic work or your teeth have shifted a bit since wearing braces as a child, aligners are a simple and effective treatment for misaligned smiles.
Whether you've never had major orthodontic work or your teeth have shifted a bit since wearing braces as a child, aligners are a simple and effective treatment for misaligned smiles.

Initial Consultation

During a consultation at our Rockville, MD, dental office, Dr. Siegel will assess the health of your teeth and gums. He will also take scans and X-rays to determine your eligibility for aligners.

Dental Impressions

After putting together a treatment plan, Dr. Siegel will take impressions of your bite using a digital handheld wand. These image files are then sent to the Invisalign lab.

Aligner Fabrication

Using 3D computer imaging, a lab technician will create a series of clear plastic aligners developed specifically to meet your needs.

Aligner Fit

Once the lab has fabricated your aligners, they will be shipped to our Rockville, MD, office. Dr. Siegel will let you try on your first set of aligners to ensure a proper, comfortable fit.

Active Treatment

You will wear each aligner for approximately two weeks before moving onto the next in the series. You will return to our office periodically so we can monitor your progress.

The Perks of a Straighter Smile 

Boosted Confidence

Your smile factors heavily when making a first impression. A straighter smile with no gaps can make you feel more self-confident at work, in social situations, and in other aspects of your life.

Easier to Clean

Crowded and crooked teeth can be difficult to brush and floss effectively. Straight teeth that are evenly spaced are easier to clean, reducing serious health risks like tooth decay and gum disease.

Improved Oral Health

Misaligned teeth can affect the alignment of your jaw, which can cause joint pain, headaches, and teeth grinding (bruxism). Straighter teeth and a properly aligned jaw can reduce these pains and prevent TMJ disorders.

Better Function

Straighter teeth can improve your enunciation, allowing you to speak more clearly. Your biting and chewing abilities will also improve, allowing you to eat a wider variety of foods.

Is Invisalign 
Covered by Insurance?

Many dental insurance plans partially cover Invisalign treatment. Our financial experts are happy to check your benefits and file claims on your behalf.

In addition to accepting most major dental insurance plans, we also offer flexible financing options. Ask our team about:

  • CareCredit®
  • The Smile Club
  • Interest-free payment plans
  • Pay-in-full discount

Also Offering SureSmile Clear Aligner Treatment


In addition to Invisalign, Dr. Siegel also offers SureSmile®. SureSmile is another clear aligner system that provides many of the same benefits as Invisalign. However, SureSmile may be able to treat complicated cases of malocclusion that Invisalign cannot address. We can compare treatment options and which one would be right for you during your consultation.
