Dr. Louis talks to his patient.

Dr. Louis is a leader in Computer Guided Dental Implant Surgery where implant surgery is performed via 3D planning providing the most accurate Implant placement with the least amount of invasiveness and discomfort to the patient. This technology allows Dr. Louis to insert an implant or implants, then place a crown or bridge the same day. It also allows Dr. Louis to extract a tooth or teeth, insert an implant or implants, then place a crown or bridge the same day.

Dr. Louis is in the forefront when it comes to treating patients who have periodontal (gum) disease. The relationship between periodontal disease and our overall health is well-documented. Periodontal disease can lead to, exacerbate, and make one more susceptible to: cardiovascular disease, diabetes, Rheumatoid Arthritis, Alzheimer’s, pulmonary disease, gastrointestinal disorders, cancer and low birth weight pre-term babies. Periodontal disease can also compromise the outcome of orthopedic surgery, organ transplant surgery and other types of invasive surgery.

Dr. Louis provides state-of-the-art molecular testing for use in the assessment and treatment of periodontal disease by providing specific bacterial analysis as well as individual genetic periodontal disease susceptibility information. The Center also provides a salivary DNA test that determines who is at increased risk for human papillomavirus related oral cancers.  
Doing and caring more than is expected, maintaining the highest standards and careful attention to the smallest detail while providing excellence, experience, compassion and commitment: these are the values of Bethesda TMJ and Dr. John V. Louis.
