Seacoast Periodontics & Dental Implants

Our primary goal is to save teeth whenever possible. We provide scaling and root planing, laser and traditional periodontal therapy, crown lengthening, gingival (gum) grafting, and bone grafting. We perform tooth extractions when necessary and place dental implants and utilize bone grafts and sinus lifts as needed. We offer oral and IV sedation for anxious patients.

Our practice incorporates advanced technology to achieve the most precise and effective treatment. We offer cone beam 3D imaging, digital radiography, laser treatment, microsurgery and piezosurgery. These approaches have been validated by rigorous clinical research. But our technology never substitutes for a close interpersonal relationship with you.

The critical components of successful periodontal or implant therapy are a comprehensive diagnosis and an honest assessment of your individual goals. Before starting treatment you should know what to expect during and after treatment. Please click below to learn about your consultation appointment and to read our pre-op and post-op instructions.
