• The Delta Dental Difference

To help control periodontal disease, Delta Dental recommends four periodontal maintenance visits per year for those individuals with moderate to high risk of progressive periodontal diseases.

Most patients with recurrent inflammation of the gingival tissues (gingivitis) without bone loss are adequately treated with one or two cleanings per year. In these cases, a dental prophylaxis will preserve the periodontal tissues.

For patients with a history of susceptibility to periodontal diseases, periodontal maintenance needs to be conducted at more frequent intervals. Statistical modeling and Delta Dental’s analysis of its own claims data show that these nonsurgical benefits are more economical than periodontal surgery. These procedures are also health-preserving and reduce tooth loss compared to those periodontal patients who do not receive these therapies. Tooth loss is a major expense in the dental system because tooth replacement costs are great whether the tooth is replaced by a conventional bridge or a dental implant.
