BEST DENTIST IN AMINJIKARAI! Drinking too much alcohol or washing your mouth with an alcohol-based mouth rinse can dehydrate your mouth. Limit yourself to one or two drinks and drink enough water to keep yourself hydrated. The body converts much of the alcohol consumed into acetic acid, which has a foul smell. Alcohol can damage the esophagus, leading to heartburn and acid reflux, contributing to bad breath. If you suspect that your breath is off-putting to others, schedule a checkup. In just minutes we at Apple Dental can assess your oral hygiene and determine not only the cause of your bad breath, but provide a care plan to eliminate it.
