Dr. Jeffrey S Rein, DDS

My ENT, Dr. Joel Portnoy referred me to this practice for my Sleep Apnea. Dr. Rein and Gina helped get me fitted for a Sleep Apnea oral appliance. It is life changing! I snore much less and I no longer keep my wife up at night. I also awake more rested and refreshed. I later decided to switch completely to the practice for all of my dentistry needs (e.g. cleanings, etc.). All of the staff are courteous, professional, and knowledgeable. I would highly recommend this practice to anyone.

Was looking to help from the start and made me feel very comfortable.

fantastic and so easy. very little pain and it was over so quickly. years ago i had an issue with a novacain inject....no more since i found this caring team with their fancy laser

After numerous other remedies (CPAP, Inspire and other Oral Appliances), the staff at Long Island Smile has helped me get on a path to better sleep. They also recommend other options that may help my individual situation as well!

I was completely blown away with the amount of time and patience that Dr. Rein dedicated towards me on my full exam. He was very detailed. The staff is very friendly and I was greeted with a huge smile each time I arrived at the office.

I had a wonderful experience at Dr. Rein's office. Everyone is pleasant and knowledgeable. I am using a mouthpiece for sleep apnea and thanks to Dr. Rein and Gina, I have my life back. My energy is back and I am very happy.

I have suffered with sleep apnea for over 15 years. This developed after my work as a NYC firefighter at the WTC. I was unable to get relief from any of the CPAP devices that I used. Finally after over 10 years of frustration I learned about the OPTISLEEP oral device. It worked from day 1 and has improved my quality of life. I am very thankful to all at LI Smile, especially Gina. She made the process a pleasure.

My visit was exceptional. Wonderful staff and service.

Had a great experience here. Dr. and staff were great. I have had good results with sleep appliance.

I've tried every type of remedy for my sleep apnea. The oral appliance is far and away the best solution I have ever tried! The team of Dr. Seltzer, Dr. Rein, and Gina were exceptional!

i had the cpap and there is no comparison to the device that dr. seltzer had made for me. i am sleeping soundly with limited snoring. game changer for me.

my experience was greater that my expectations thought. everyone friendly, out going.

The staff and doctor Rein were very helpful with questions, and concerns. I am extremely happy with my results.

staff amazing i can sleep, i can sleep,

The entire staff at Smile Dental Sleep Medicine has been very friendly, caring and professional. The oral device they prescribed to address my sleep apnea condition is comfortable to wear and is working well.

Would highly recommend to others

Thank you Doctor Rein, for a long time I dealt with sleep apnea and even went through CPAP therapy. I am grateful to say that I now am having deep sleep each night with dreams (which never was the case). Words can not say how relieved I am that you helped me!

The Staff also at your office has always been very helpful and flexible to work with my schedule.

my experience with staff at long island smile has been great
