Fixing unused corrupted pages.

We find corrupted pages at innodb file.

mysql/bin/innochecksum -s 7034440 ibdata2
InnoDB offline file checksum utility.
Fail; page 7034440 invalid (fails log sequence number check)

But they are not used by any tables data, since full mysqldump for the DB passed successfully.

Can we assume that the corrupted pages will be automatically fixed on use?
Or should we dump/restore DB completely?
