What Is a Diagnosis?

Lakewood Ranch Dentist


At O’Brien Smiles, diagnosing periodontal disease begins with a thorough evaluation of the gums, teeth, and supporting bone. Dr. Allison O’Brien carefully examines the gums for signs of inflammation, bleeding, recession, and other indicators of gum disease. Periodontal probing is used to measure the depth of the spaces between the teeth and gums, known as periodontal pockets. Deeper pockets can indicate infection and damage to the supporting structures of the teeth. Digital X-rays are also an important part of the diagnostic process. These images allow Dr. Allison O’Brien to evaluate the bone supporting the teeth and identify bone loss that may not be visible during a visual examination. By combining clinical findings with advanced imaging, it becomes possible to determine the stage and severity of periodontal disease.

An accurate diagnosis allows Dr. Allison O’Brien to recommend the most effective treatment plan for each patient. Early detection helps control infection, protect the supporting bone and gum tissue, and prevent further damage that could eventually lead to tooth loss. Careful periodontal evaluation is an essential step in maintaining long-term oral health and protecting the stability of your smile.

Dr. Allison O’Brien and her staff are INCREDIBLE!!!! I have never received such amazing dental care in my life. Dr. O’Brien loves what she does and always puts me at ease. She is so patient and generous with her time. My cousin in Philadelphia is a dentist and I asked him if he could research a dentist in my area that REALLY is a TMJ specialist. He found Dr. O’Brien because he researched dentists that continually do extra training at a special institution in Tampa. Dr. O’Brien is that that Dentist!!! I will always be so grateful to her and her staff❤️❤️❤️❤️
