Services
Invisalign
Invisalign uses clear, removable aligners to straighten teeth discreetly. Custom-designed for each patient, these aligners gradually shift teeth into proper alignment without the need for traditional braces. Ideal for adults and teens seeking a nearly invisible orthodontic solution.
Braces
Metal braces offer a reliable, cost-effective method for correcting misaligned teeth and bite issues. Modern designs feature smaller brackets and advanced wires for improved comfort and faster results, suitable for patients of all ages.
Orthodontic Consultations
Complimentary consultations include digital imaging and X-rays to assess orthodontic needs. We develop tailored treatment plans, estimate timelines, and discuss financial options to ensure patients make informed decisions about their care.
Flexible Financing
We offer customizable financing options, including down payments, monthly installments, and multi-family discounts. Our team assists with insurance verification and FSA/HSA documentation to make orthodontic care accessible and affordable.
Sierk Ortho Shuttle
The Sierk Ortho Shuttle (SOS) provides free transportation for patients to and from appointments. This service ensures convenience for families, particularly for school-aged children requiring orthodontic visits during school hours.
