I have officially been a patient here for a year. My oral health was severely neglected after years of no profesional care. Thankfully Dr. Loomba and her staff have done an amazing job caring and addressing my dental health needs. I left my office visit today with nothing but good news, no cavities, cleared x rays, and my gums are doing way better than a year ago. Dental care can be costly, but they are upfront with their costs before moving forward with any treatment. They recommend based on your needs both orally and financially.
