It all begins with a no-cost, no-pressure consultation. We'll evaluate your smile, answer every question, and walk you through the treatment options best suited to your goals.
Using advanced digital imaging and our doctors' expertise, we design a precise, customized plan built around your unique smile and timeline.
Whether you choose braces or Invisalign®, our team guides you through every step with gentle, skilled care — keeping you informed and comfortable throughout.
The day your treatment is complete, you'll walk out with the confident, beautiful smile you've always wanted — and a relationship with a team that genuinely cheered you on the whole way.
The best way to find out is with a professional evaluation. We offer complimentary consultations at both of our Tampa locations — no referral needed, no cost, no obligation. Early assessment can make a significant difference in the ease and success of treatment.
The American Association of Orthodontists recommends a first evaluation by age 7. At this stage, Dr. Goodnight or Dr. Mathews can identify developing issues and, if needed, recommend early treatment that guides healthy jaw and tooth development.
Invisalign® uses a series of clear, removable aligners that are virtually invisible — ideal for patients who want a discreet option. Traditional braces, including our Empower® self-ligating system, offer exceptional precision and are often the best choice for more complex cases. We'll help you find the right fit during your consultation.
Absolutely. We treat patients of all ages at Goodnight Orthodontics. Adult orthodontics is more popular than ever, and we offer a full range of options — including discreet Invisalign® — designed to work around busy adult lives.
Empower® self-ligating braces use a specialized clip instead of elastic ties to hold the wire, which reduces friction and often results in a more comfortable experience and potentially shorter treatment time compared to conventional braces.
Two-phase treatment is an approach that addresses developing jaw and bite issues early (Phase 1), then completes full smile alignment later when all permanent teeth have erupted (Phase 2). It can simplify future treatment and lead to better long-term results for younger patients.
Simply call either of our Tampa offices or request an appointment online. Your first consultation is completely complimentary — our team will walk you through everything and make sure you feel confident and informed every step of the way.
Join the hundreds of Tampa families who've trusted Goodnight Orthodontics with their smiles. Your first consultation is completely free — no obligation, no pressure, just expert care and a clear path forward.
