I am probably the wrong person to rate dental practice because I’m inherently biased! Yes, I love dental cleaning and scrapings! And, Dr Ortega is one the best! She and her caring staff are all so professional and friendly. Dr. Ortega listens to my concerns and never rushes me. I feel like I’m in good hands when I see her. If you have had the unfortunate experience of being with a “bad” dental practice then Dental Cosmetix is the right place for you!!!!
