Dr. Rein did my two fillings today with the new laser machine and it was AMAZING. No pain, stress, or worry. I highly recommend doing the fillings here with them. Always the best to their patients and great new laser for fillings!
Came to Long Island Smile to finally make my teeth a priority. As soon as I walked in I had a pleasant greeting from the front desk staff. The dental technician had a smile the whole time and made be feel relaxed. Dr. Rein was kind, gentle and didn't rush my appointment like other dentists I have had in the past. I feel comfortable with his knowledge and suggestions. Will be back tomorrow to start my work. Thank you Long Island Smile! Leticia

laser is the way yo go. No pain, no numbness. Was a good experience... considering I'm getting dental work done.
Getting my cavity filled this morning was a quick and easy process! The staff assured me Solea was safe alternative to anesthesia and drilling. While I was nervous at first, the procedure went extremely well and was completely painless.
Dr. Rein is the best! Great results and a great manner.
He is very caring and helpful with his patients
I was a Sleep Apnea sufferer for many years. I've had many operations and used a CPAP machine to sleep with much difficulty. After seeing Dr. Rein and having a SOMNO MED device made my life has changed. My AHI of 73 went to a 0.5. I sleep through the night without any machines or hoses. UNBELIEVABLE !
I came to this office with a diagnosis of severe sleep apnea and attempts to use a CPAP machine did not help at all. I was fitted with an oral appliance to use while sleeping and it was life changing. I am sleeping comfortably every night and feeling refreshed in the morning. Morning headaches when I wake up have subsided completely. My wife says I sleep quietly now instead of the loud snoring. She said she is jealous at how comfortably I look when I sleep now. I regul...
Great staff, nice office, easy comfortable experience. Thank you for providing me top dental care.
My experience has been extremely favorable. I was able to transition from a CPAP, which was very uncomfortable and not travel-friendly, to the oral sleep appliance, which has dramatically improved me quality of life. I no longer have to lug the CPAP when I travel and am able to go through security much faster. The appliance is also much more comfortable. I hardly notice it at all!
Knowledgeable and experienced.
Always professional, caring and thorough!
Extremely professional. Explained every aspect of the appliance. Appointments that fit my busy schedule. Excellent office staff that understand friendly customer service.
Very positive experience.
Office staff is very accommodating and thoughtful.
Very patient and nice demeanor.
Finally, a night's sleep. Had no difficulty getting used to the guard as I had used a mouth guard for TMJ for years. Sleeping soundly with no discomfort whatsoever and no more TMJ headaches.
Professional service and care.
Fantastic, Dr. Rein you have saved my life and for that I will always be grateful.
I have never felt so pleased in an office!
Very accommodating and through. Always takes the time to explain everything.
