Periodontogram frequency

[macbar]

I had a periodontogram done about a month and half ago. I am planning to have braces but now the doctor has said that before doing the orthodontics I would need to do another revaluation periodontogram. This would be only 3 months apart so I am not so sure any significant benefit or reason except to hit me where it hurts in my wallet. Any advice?

Not necessary; ask him what he thinks has happened in 3 months. If your periodontal condition is so bad as to require 3-monthly charting, then you wouldn't be getting braces.
