Invisalign uses a series of clear removable aligners (pictured to the left) to straighten your teeth without metal wires or brackets. Invisalign has been proven effective in clinical research and in orthodontic practices nationwide. In fact, over 70% of all U.S. orthodontists are certified to treat patients with Invisalign.
Dr. Lewkowitz is proud to offer the latest in Orthodontic treatment including the finest clear braces made of pure sapphire crystals that are very smooth and aesthetic, small and smooth metal braces, and invisalign. The American Association of Orthodontists recommend that children should have their first orthodontic evaluation at 7 years old.
For prevention in general dentistry Infants should be seen by our office after the first six months of age, and at least by the child's first birthday. By this time, the baby's first teeth, or primary teeth, are beginning to erupt and it is a critical time to spot any problems before they become big concerns.
For decades, fluoride has been held in high regard by the dental community as an important mineral that strengthens tooth enamel, which thereby helps to prevent decay of tooth structures. Water fluoridation is endorsed by nearly every major health and safety-related organization in the world.

Communities make it a common practice to "fluoridate" their drinking supplies in order for the general population to benefit from this inexpensive and effective preventative treatment.According to the American Dental Association, more than 144 million U.S. residents in more than 10,000 communities drink fluoridated water, most from public water supplies with sodium fluoride added artificially.
An estimated sixty-five percent of Americans have bad breath. Over forty-million Americans have "chronic halitosis, " which is persistent bad breath. Ninety percent of all halitosis is of oral, not systemic, origin. Americans spend more than $1 billion a year on over the counter halitosis products, many of which are ineffective because they only mask the problem.

We love Dr. Lewkowitz. She is great with my kids, they feel comfortable with her and she makes them laugh (me too). I would follow her anywhere, and we have...I can’t say enough good things about her and her staff. I highly recommend Dr. Lewkowitz. The Kardum’s

If you’re looking for a qualified and professional orthodontist I highly recommend LIDG dental group! Dr. Lewkowitz shows such compassion towards her staff and her patients and always ensures that she takes care of them as well. Not to mention, she will keep you entertained and make your stay as comfortable as possible. During the Covid-19 pandemic all protocols were in place and of a high standard. As a 15 year old patient, I saw immediate changes with braces in a matter of 2 weeks! Dr. Lewkowitz provides excellent follow up care and she’s always available for questions and concerns!

Let me just say this is the cleanest and far most the best dentist i ever been to. From the receptionist (jenny) to my hygienist (jenn) and of course the amazing dentist Dr. Seo. Whenever i went to other dentists office for my cleaning, they don't wrap the chairs in disposable plastic (and who knows if those seats are sanitized) and i will come out of there looking like a hot mess; blood splats on my cheeks and my clothes all wet. But jenn, i don't know how she does it, not only my teeth are shining, but I'm out of there dry and with a clean face. She's also very gentle with

Dr Lewkowitz is one of a kind; very professional and makes every office visit fun with her bubbly personality. My teeth would not be as perfect as they are without her. She is a pleasure to deal with and I highly recommend her.

This is a great dental practice. From start to finish, Dr. Patricia Seo (Huynh) and staff were extremely tight on communication, insurance processing, dental procedure, sign out, and follow up. Dr. Seo is very thorough, gentle, and knowledgeable. I highly recommend Dr. Seo.

My friend recommended this office to me when I had a chipped molar and I was desperately in need of dental work. I would definitely recommend this office! They have a parking lot which is a big plus, and the office is so nice! It doesn't have the typical dental office feel and the interior is so modern. The best part is there was no wait. I'm from the bayside/flushing area and there's ALWAYS a wait whenever I go to the doctor's.

Also, I usually HATE getting a cleaning because it hurts so much and I can't stand the sound. I went back another time to get a cleaning and

Love my dentist. She's skilled, friendly and informative, and doesn't push unnecessary procedures on you. I don't feel nervous at all whenever I come here.

Receptionist is the sweetest lady on Long Island. Why are nice receptionists in the healthcare industry so tough to come by? I feel so lucky to have found this place.

Office is very clean and smartly decorated, without the tacky or clinical feel of a dentists office. Don't let the outside of the building fool you.

Dental offices are pretty high end and modern to begin with but this place takes the cake. Very relaxing and modern place and extremely clean ( the bathroom is spotless and looks like it should be in a high end hotel).
I moved into area and brought my whole family in. They are excellent with kids my son loved his visit. Doctor is very personable and very clean, he even had protective coverings over handles of the light and his most used instruments handles to be replaced after ever visit. We were seen as soon as we finished first timers paperwork and were taken care of very timely. Everyone had

A+ What can I say, this place from the construction to the overall visits are SPOT on every time you go.

You feel as if you are at home. The staff is very welcoming, the doctor (Kim) is very nice and very good. The place is no joke, very all about their patients and high-tech. Appointments are made, texted confirmations, e-mails, it's just top notch.

Appointments are planned on a timely base, you are never waiting for someone to finish, and if you are it's very rare. You would think the place doesn't get much business, but no! It's just managed very well.

I found this randomly
