Entries in suspect_pages but checkdb shows no error

I am using Microsoft SQL Server 2016 (SP2-GDR) (KB4505220) – 13.0.5101.9 (X64) Jun 15 2019 23:15:58 Copyright (c) Microsoft Corporation Standard Edition (64-bit) on Windows Server 2012 R2 Standard 6.3 (Build 9600: )

Yesterday, I got two entries in “suspect_pages” for the same database. One of event type 1 and one of type 2

1 = An 823 error that causes a suspect page (such as a disk error) or an 824 error other than a bad checksum or a torn page (such as a bad page ID).

2 = Bad checksum.

database_id file_id page_id eventtype   error_count last_update_date 8           1       1482057 1           1           2019-11-14 14:40 8           1       1482057 2           1           2019-11-14 14:40 

I found the object related and they both point to the same table on the database.

DBCC TRACEON (3604); DBCC PAGE (8, 1, 14823057, 0); DBCC TRACEOFF (3604);

I had a valid backup of before the corruption and couldn’t afford a down time so I took a backup of the corrupted database, restored my backup on a new name. I dropped the corrupted table and then recreated it from the valid backup.

Today, I restored the corrupted database backup that I took yesterday on a test server and when I run a full checkdb, it detects no corruption.

DBCC CheckDB() WITH No_INFOMSGS, ALL_ERRORMSGS

How is it possible that the backup I took from a corrupted database (according to suspect_pages) doesn’t have any problems? Can those entries in suspect_pages be a false positive?
