I've been going to Dr. Alhaouasli Dental Center for 13 years now. He has been providing dental services from teeth cleaning, teeth whitening, cavity treatment, as needed on my teeth. I haven't had to make multiple visits for a single tooth. Dr. Alhaouasli has managed to fix the problems at the scheduled appointment. Also, he always tries to save the tooth versus extracting it. His office staff are very helpful and accommodating. I once had to bring in my kids into the office and his staff watched them for me as I was getting treated. Despite the fact I moved to Salt Lake City 8 years ago, I still

This office is the most unprofessional office I have been to in my life. I went here to ask about getting my wisdom teeth removed. 1st the dentist said that he wouldn't remove them but instead would fill the cavities. I have had several other dentists recommend removing them since the cavatines were deep and prone to infections. I kindly asked if he could remove them and he said he would. When I came in the morning I was going to remove them, after I had already taken off work, they told me that I couldn't get my wisdom teeth removed and that they would instead fill some cavities. I told

I'd like to start by saying the receptionist and dental hygienist/assistant are very kind and helpful. The one star only applies to the Dentist.

I had cavities filled and unfortunately was not numbed completely and it was extremely painful. I also realized later that day (after the anesthesia wore off) that there was a "high" filling that was making my bite feel weird so I called and went back same day (nice of them to accommodate though I wish I had waited at least a day since my mouth was still in so much pain. He tried to fix it but I could tell he was getting frustrated and

Don't come here if you have Dentical. I haven't been to the dentist in quite a while due to some fears and trust issues. (SIDE NOTE: Anyways, I chose this place, and took a friend with me. My friend's mom, Father in law, and mother in law all own(ed) their own practice, so my friend is very knowledgeable when it comes to dentistry.)

Started off with the hygienist doing X-rays, the machine was very old and she could not seem to operate it very well, she kept like fighting with it to get it to stand still.
Then, she polished my teeth, and scraped plaque off the bottom front 3 teeth

Yesterday, I was feeling a absess tooth, and the Dentist, whom has had several years did a great job removing 6 teeth, no pain really at all today.

Dr. Hassain has provided with experienced and quality care at a reasonable price. Because I had a lot of previous dental work, he has improved my dental health. When I have an emergency, he has provided me with same day service, which I appreciate because I work with the public.

I make appointments and I never have to wait. I've also been going here my whole life and I'm not planning on changing that anytime soon.

Dr. Helen Ninh is super nice and gentle. She makes me actually want to get my teeth cleaned every now and then. She is such a delight and makes sure you feel comfortable. She beats the whole scary dentist stereotype.

Dr Hassan is an amazing dentist!!!! My son sees him every 6 months...and is always so great with him! I finally got the nerve to go to the dentist after 8 years and found I needed a root canal. I was shocked at the lack of pain and how quickly he did it! Even the next day, no pain! Highly recommend him!!!
