We’re welcoming new patients!
Summit Dental Health, formerly Siouxland Dental Health, has been a fixture in the Sioux City community since 1929. Conveniently located near the corner of Pierce and 22nd Streets, we offer high-quality dental care with a wide range of services. We’re available for evening appointments two days a week and accept most dental insurances, making it as easy as ever to take care of your smile. No insurance? Ask about our dental savings plan!
Call today to schedule an appointment with us. We look forward to building a long-lasting relationship with you and your family.
New patients can now schedule online! If you're already a patient, please call your practice directly to schedule. You'll find a list of insurances we currently accept on our payment options page. If you do not see your insurance listed, please contact our patient services team at (402) 799-1147 so we can check for a nearby practice that may accept your plan. Please note that any patient portion of payment is due at the time of service.
