Can't Sleep Center - Santa Ana, California

Let's start with the office, it's your an average older business building, but once you walk into the office you feel like you walked into an office in Beverly Hills. Beautiful, but not gaudy chandeliers in the lobby and each room. Plus it smells so nice in there and the lobby has a beverage fridge for patients, never seen this.

Now for the staff, WOW! The staff is professional, caring and make it clear they are there for all your needs. This goes from the front office to the Dr/Dentist. Bottom line you really need to try them out, you will be so happy you did.

As a military veteran, I was referred to this office by the VA. Since working with them, they have been very nice and professional. I’ve had a sleep apnea device issued to me and the dental office has helped me fine-tune the device with 6 followups. I think it’s exceptionally impressive that they stay on top of technology and scan your teeth into a digital model instead of manual imprints. I have very much enjoyed every visit I’ve made with them.

I came in on a referral from the VA to fit a sleep apnea mouthguard. Dr. Abraham and his team are extremely professional, expert and friendly. They explained the different options and oros and cons, and the whole process has been easy and understandable. Dr. Abraham gave a lot of very helpful advice and set expectations well. I recommend this office and team for anyone with dental needs. 10/10 great experience.

I’ve struggled with teeth grinding and TMJ for years. Every dentist I saw just told me to use a night guard and that was it. But my experience at Can’t Sleep Center with Dr. Kareem was completely different—it was truly life-changing.

Dr. Kareem didn’t just hand me a night guard; he took the time to dive deep into my history and perform a thorough clinical exam. He evaluated everything—the TMJ, chewing muscles, my bite, and even used a 3D scanner for a precise bite assessment. Instead of a one-size-fits-all solution, he developed a comprehensive plan that included medication adjustments, muscle exercises, cognitive therapy for my muscle habits, and a natural, holistic approach. No medication dependency, no quick fixes—just real solutions.

This journey required multiple visits, and with every visit, I saw noticeable progress. I’m now completely free from TMJ pain, my teeth no longer hurt, and I’ve stopped breaking crowns. Dr. Kareem is incredibly talented and has an exceptional ability to create a personalized treatment plan that actually works. I can’t recommend him and his team enough. If you’ve been stuck with temporary fixes, this is the place to go for real, lasting results!

I travel often and struggled with obstructive sleep apnea, heavy snoring, and TMJ pain. CPAP machines were unbearable and impossible to travel with. Dr. Abraham at Can’t Sleep Center designed a custom oral device that’s compact, effective, and life-changing. My snoring is gone, TMJ pain is greatly improved, and I finally wake up feeling refreshed—even on the road. I highly recommend Dr. Abraham for anyone seeking a better solution to OSA!

Mina Salib

I was referred to Can’t Sleep Center by my pulmonologist after struggling with my CPAP machine. It just wasn’t working for me—I’d wear it all night but still wake up feeling exhausted. Dr. Kareem and his team introduced me to a customized oral device, and it’s been a total game-changer.

The device is incredibly small, fits perfectly, and has eliminated my snoring completely. My wife couldn’t be happier, and I wake up feeling refreshed and full of energy. I no longer need naps or rely on caffeine to get through my day. My demanding job requires me to stay sharp and focused, and this treatment has made a noticeable difference. Even my workouts have improved because I finally have the energy to push myself.

I can’t thank Dr. Kareem and the Can’t Sleep Center team enough for their expertise and care. If you’re struggling with sleep apnea and looking for an alternative to CPAP, I highly recommend them!

Dr. Abraham is an amazing dentist who really cares for his patients! I have been coming here ever since I was little, and will continue to come:) I have had issues with TMJ and the pain that comes from it, but Dr. Abraham was committed to easing my pain. He is truly the best dentist ever!

I started using the MAD (Mandibular Advance Device) provided by
Dr. Kareem Abraham.
Dr. Abraham's facilities are very comfortable facilities, and
maintained very clean. Parking is also very accessible.
Additionally, Dr. Abraham and his staff are very courteous and
warm.
Dr. Abraham is extremely attentive to us the patients, and him and
his staff are very focused on delivering very professional and
compassionate care, from the fitting of my MAD to the use of the
MAD.
I highly recommend Dr. Kareem Abraham.
Separately, from the very first morning I saw an immediate benefit
to my Obstructive Sleep Apnea (OSA), from the MAD.
I have been using the MAD for two weeks. On the first night of
trying it, the first few minutes, there was a little anxiety on my part,
because it was very hard to swallow and my breathing was more
labored; however, I removed the MAD, drank some water, and laid
down on my side, and that immediately helped. From the first
morning to the present, I have woken up with about 80-90%
reduction in my grogginess (and thus more clear headed and alert)
and my headaches have also decreased significantly.)
