It is not unusual for recent dental restorations to
be sensitive to hot, cold, or pressure. This sensitivity
should decrease with time. If sensitivity from a recent
dental restoration worsens or persists, contact your
Whitening can also temporarily
cause mild sensitivity during treatment that disappears
within a few days.
Sensitivity due to a dental problem will worsen with
time and become a toothache. A toothache is not
like a headache. It won't just go away, even if the
pain temporarily subsides. The problem that is causing
the pain will just get worse, as will the pain, and
simple treatment may no longer be possible. (See our
pages on cavities, root
canals, abscesses, and extractions to see how
a cavity progresses from a minor to a major problem).
At the first sign of a toothache, contact your dentist.
