My kids hate the dentist and have a really bad gag reflex so it makes most visits a total nightmare! We went here for a cleaning and the doctor is... read more so nice gentle and patient. My son who we had to take to get put under for his last dental treatments because of such bad anxiety and fear felt so confident with this doctor after his cleaning he allowed him to do his filling with just laughing gas and numbing. I was shocked since he normally works himself up so bad he makes himself sick all other doctors won’t even bother. I highly recommend anyone looking for a pediatric dentist to come here ! He really is awesome and my kids love him ! The office is super clean , kid friendly with video games, wall murals , tvs in the ceiling so kids can watch during treatment , and state of the art equipment. I highly recommend him ! He really is perfect for this job ! So glad we found this office !

I brought my teenage son and daughter here as first time patients and they absolutely loved it! As a mother I greatly appreciated all the communication that was provided throughout... read more the visit. Dr Ruben even squeezed my son in to get his sealants done in the same visit! We will definitely be back! I plan on bringing my son for an orthodontist consultation next month. Thank you so much for everything Dr. Ruben and staff!

If you have a child with special needs or just one with high anxiety when it comes to the dentist, look no further! Dr. Ruben Sandu and his staff are... read more absolute rockstars. My son has a lot of fear and anxiety around new experiences, and let's just say our first visit wasn't exactly smooth sailing. There was some serious kicking, screaming, and unfortunately, even some throwing up outside the office. Through it all, Dr. Sandu and his team were incredibly patient and understanding. They never made us feel embarrassed or like we were doing something wrong. They just kept a calm and positive atmosphere, and even managed to get a peek at my son's teeth! What really impressed me was the follow-up call we received from Dr. Sandu himself. He wanted to check in and see how my son was doing after the whole ordeal. It showed a genuine level of care that goes above and beyond. Finding a dentist who can handle – and even thrive with – special needs kids can feel impossible. But the office Dentistry 4 kids is a true gem. We're so grateful to have found them!

We had a great first experience with Dr.Ruben and staff. The office is very kid friendly. My kiddos loved the underwater theme. Everyone from the receptionist to the doctor was... read more kind and patient. Dr. Ruben explained everything to my kids before he did it and then showed me all of his findings. It was my kids first visit to any dentist, they made them feel so comfortable that even my 3y old cooperated and both kids said they had liked it.

Ok, Dr. Ruben is one amazing dentist! My 9 year old had a cavity for over a year, and we tried 3 dentists and none of them could do... read more it because he was very nervous and would not stay still. But Dr. Ruben was patient and took time to explain him what he does and was able to do that one cavity without any complaints from my son! I was left speechless and so so so happy!! I cannot recommend this place enough! You won’t regret choosing this dentist for your children.

Dentistry 4 Kids has been amazing with treating my 7 year old. Dr. Ruben was AMAZING at ensuring the kido felt safe, reassured and comfortable. He talked her through everything he... read more was doing and made the "scary dentist tools" fun and friendly. Video games in the waiting room and TVs on the ceiling help the kids find it to be a fun place. ABSOLUTLEY 10/10 WOULD REVOMEND.
