Silent reflux can genuinely affect dental health, since acid reaching the mouth — even without any noticeable burning sensation — still has the same erosive effect on tooth enamel as classic acid reflux.
Why this can happen without you noticing
Because LPR often doesn't cause the classic heartburn sensation, someone can have acid reaching their mouth regularly during sleep or throughout the day without being aware reflux is happening at all — the first sign might actually come from a dentist noticing unusual enamel wear or increased cavities during a routine checkup.
What dentists look for
Erosion patterns on the back (tongue-side) surfaces of the upper teeth are a classic sign dentists associate with acid reflux, since that's where acid tends to pool during reflux episodes. Increased sensitivity to hot, cold, or sweet foods can also be an early sign of enamel thinning.
What to do if this comes up at a dental visit
If a dentist raises the possibility of reflux-related enamel wear, it's worth following up with a doctor to evaluate for silent reflux specifically, even in the absence of any other symptoms you might have attributed to a completely different cause, like just "sensitive teeth" or grinding.
