Located just a short drive from Exeter, our practice is proud to offer a full range of orthodontic solutions, including Invisalign, traditional braces, and clear ceramic braces. Whether you're a teen exploring your options or an adult finally ready to invest in your smile, we're here to help.
Invisalign offers a discreet, flexible alternative to traditional braces. Using a custom series of clear aligners, Dr. Walsh helps align your teeth gradually and comfortably, without metal brackets or wires. With his specialized training in clear aligner therapy, even complex cases can be handled confidently here in Stratham. Patients love the convenience, virtually invisible appearance, and life-friendly lifestyle Invisalign provides.
Traditional braces remain a highly effective treatment option, especially for younger patients or those needing more complex tooth movement. At Great Bay Orthodontics, we make braces feel less clinical and more like a journey toward your new, confident smile. We offer both metal and ceramic bracket options and use the latest techniques for faster, more comfortable results.

For patients who want the power of braces with a subtler appearance, clear ceramic braces are a wonderful middle ground. These blend smoothly with your natural teeth color, delivering strength and precision without standing out. They’re especially popular among adult patients in Exeter who are seeking understated yet effective solutions.
We take the guesswork out of getting started with orthodontics by offering a completely free consultation. This includes a full expert assessment by Dr. John Walsh, personalized honest advice, and your initial diagnostic records, all with no pressure, no obligation. This offer is our way of helping Exeter residents feel confident and informed before beginning treatment.
A standard dental visit typically includes a professional cleaning, a thorough examination by the dentist or orthodontist, and any necessary digital x-rays. At Great Bay Orthodontics, our new patient consultations go a step further, with detailed analysis, initial diagnostics, and custom treatment planning, all done with your comfort and goals in mind.
