Conventional wisdom would dictate that there be absolutely no air space within the tooth during diving or even flying. A barodontalgia, while very rare, can happen. Even the air space left at the end of an incomplete root canal filling can cause a problem--sometimes years later. You shouldn't dive until the root canal is completed AND either a temporary filling is placed WITHOUT a cotton ball inside the tooth or the tooth has been permanently restored.
Check the Scubadoc site previously listed it has my long winded answer.
Be patient and enjoy diving,
