Straight teeth are an important part of any smile. Misalignment can undermine your appearance and make dental hygiene more difficult.

Invisalign® clear aligners are a discreet, comfortable, and incredibly popular alternative to metal braces.

Dr. Louis J. Buono​ offers Invisalign at his Long Island, NY, practice to improve oral health and self-esteem.

Real Patients. Real Results. An Invisalign Transformation

This 24-year-old patient wanted a straighter, more symmetrical smile. Dr. Buono made her dream a reality thanks to aligners that are much more discreet and less bulky than braces.

Straighten Your Smile Without an Orthodontist

One of the benefits of Invisalign over traditional braces is that you don't have to see an orthodontist for treatment. Dr. Buono can create a customized Invisalign treatment plan right at his Long Island practice. Many existing patients appreciate this benefit, as they already have established trust with Dr. Buono and don't have to worry about finding an orthodontist. New patients can receive the perks of Invisalign treatment while also establishing a new general dentist.

Best dentist hands down. I travel from out east to use Dr Buono. I use to have a huge fear of the dentist now I look forward to my visits. I highly recommend him. His staff is just as pleasant.

Invisalign Treatment Timeline

Your first step on the road to straighter teeth is a free consultation at Dr. Buono's Garden City, NY, practice. He will analyze your mouth to determine if Invisalign is right for you. The total length of treatment depends on each patient's smile goals, but overall, treatment time is usually equal to that of traditional braces–at least one year or more.

Dental Impressions

First, Dr. Buono will take digital impressions with our Cadent iTero scanner, which eliminates the need for messy gels and waxes. These precise images are then uploaded to our computer software.

Aligner Fabrication

The digital impressions are then sent to our trusted partner lab. There, a trained dental technician custom-crafts your aligners according to Dr. Buono's personalized treatment plan. The number of trays necessary depends on your specific case.

First Try-In

Once the aligners have been created, they are shipped to our office in Long Island. You will be fitted for your first set of aligners. Our team will also provide you with instructions for proper wear and cleaning during your visit.

Active Treatment

For Invisalign to shift your misaligned teeth effectively, your clear aligners must be worn at least 20-22 hours every day. You should only remove them to eat, brush, and floss. The aligners are typically switched out for the next set approximately every two weeks. 


Once Dr. Buono has determined that your smile has been properly aligned, you will need to wear a retainer to prevent your teeth from shifting back into their original positions. Dr. Buono can discuss your options and help you choose a retainer that will fit your preferences and lifestyle.
Helpful hint: Keep your previous aligner every time you switch to a new one. This means you will have a back-up in case you lose or break your current tray.

Keep Your Smile Healthy During and After Treatment Invisalign Can Create a Beautiful Smile for Life

With proper care, the results of Invisalign treatment can last a lifetime. Follow Dr. Buono's care instructions during and after treatment to keep your teeth and gums healthy and your smile beautiful.

Brush and Floss

Continue to brush your teeth twice daily and floss once daily during and after your clear aligner treatment. Removable aligners make it easy to eat, brush, and floss during treatment. 

Wear Your Retainer

Wear your retainer (or last set of aligners) as directed by Dr. Buono to maintain your straightened smile and keep your teeth in proper alignment for years to come.

Visit Our Office

We will schedule regular visits to our Long Island practice during aligner treatment to ensure your teeth are shifting into the proper position. Following Invisalign, you should visit our office every six months for regular dental cleanings to keep your teeth and gums healthy.

Caring for Your Clear Aligners Tips on How To Keep Your Aligners Clean and Safe

Your clear aligners will sit against your teeth 20-22 hours a day, so it is very important to keep them clean.


Rinse your mouth after you eat or drink anything besides water. You should also rinse your aligners before you reinsert them, to ensure there are no lingering food or beverage particles from a previous meal.


A great way to clean your Invisalign clear aligners is to use the Invisalign cleaning system. However, denture cleaner works as well. Only brush your aligners with a soft-bristled toothbrush and gentle soap: hard bristles and abrasive toothpaste can leave scratches and a cloudy film, making the aligners more visible when worn.


Being removable is one of the major advantages of Invisalign over metal braces, but it does mean they can be misplaced. Always keep your aligners in a safe place where they cannot be lost or damaged. Lost or damaged aligners can add to your treatment time and cost.

How Much Does Invisalign Cost?

The Simple Answer? It Varies.

Just like the amount of time you will need to wear your aligners will vary, the cost of your treatment will vary based on your individualized needs. But a beautiful, straight smile is worth every penny.

We Offer Competitive Prices

Dr. Buono's fee structure is very competitive. Plans differ, but it is possible that your insurance could cover some of the expenses. Our warm, friendly staff will work with your carrier to get you the maximum coverage available. 

Don't Let the Cost of Treatment Keep You From Smiling Contact Our Long Island Practice To Request Your Consultation

We never want the cost of treatment to prevent you from getting the care you need. Our friendly staff is happy to review your insurance plan to ensure you are maximizing your Invisalign benefits. During your consultation, Dr. Buono will go over all your options and discuss ways to meet your dental needs and budget while still achieving your desired results.

Invisalign FAQs

Girl holding Invisalign

How Long Will I Have to Wear My Aligners?

The answer will depend on your individual alignment needs. Minor misalignments could be improved in as little as six months, while more complex cases could take over a year. Dr. Buono will go over the length of your treatment plan during your complimentary consultation at his practice.

Is Invisalign Permanent?

Yes! The straightening effects of Invisalign can last your entire life. Wearing your retainer regularly ensures your teeth won't shift out of alignment so you can forever enjoy the health and aesthetic benefits of a straighter smile.

Girl with tooth pain

Is Invisalign Painful?

Invisalign gradually shifts your teeth, so it should only cause minor to moderate discomfort, the worst of which is felt at the beginning of a new set. Once you have worn that set for a few days, your teeth start to adjust, and the discomfort fades.

Woman giving a speech

Does Invisalign Affect Your Speech?

Invisalign is made of thin, smooth plastic and may mildly affect your speech. Some patients notice a slight lisp at the start of treatment. However, the longer you wear your aligners, the more comfortable you will get speaking in them.

Invisalign Trays

Can I Throw Away My Last Set of Clear Aligners?

It is a good idea to keep your previous set of aligners. If your teeth did not shift correctly, Dr. Buono can check the last trays and make any necessary adjustments. Having your previous set around can help you stay closer to your original treatment timeline if you lose or damage your current aligners.
