Is it possible for a dental specialist to place bone grafting material within a tooth's deeper pocket without the need to do flap surgery?

Probably not!: The repair of a deep pocket around one tooth has many factors that would determine the method of treatment. The type of bone defect, which tooth, where the pocket is, the doctor's access to the pocket, the cause of such an isolated pocket. Flap design is most crucial for proper access, but sometimes special lasers can be used to start the repair process. See a periodontist and weigh your options.

Not really: Dr Frieedman is correct. To access the area where bone is missing requires temporarily moving back the overlying gum tissue. Follow your Dentist's or Periodontist's instructions. And once the correction has been made do whatever is necessary to maintain your oral health.
