Bridgett is а 42-yeаr-оld аccоuntant. She is a new patient tо your office and presents today with pain on the lower left. The periodontal assessment reveals generalized bleeding on probing and probing depths that are less than 3 mm with the exception of the interproximal molar areas where 5 mm depths are noted. A review of the medical history reveals hypertension and diabetes for which she takes lisinopril and metformin. Her latest A1c was 8.6. Radiographs reveal 1 mm bone loss between the molars and a radiolucency at the apex of tooth 19. Which toothbrushing method should be recommended for this patient?
