Persistent Bad Breath: Dental Causes and What to Do
Occasional bad breath is common, but breath odor that persists despite normal home care can be a reason to look for an underlying cause.
Start with daily oral hygiene
Brush the teeth thoroughly with fluoride toothpaste and clean between teeth each day. Cleaning the tongue can also help remove odor-producing debris. Dry mouth can make breath problems more noticeable.
Dental problems can contribute
Plaque buildup, gum inflammation or periodontal disease, tooth decay, infection, poorly fitting appliances, and other oral conditions can contribute to persistent odor. A dental examination can help identify oral causes.
Not every cause is dental
Diet, tobacco use, medications, dry mouth, sinus or respiratory conditions, reflux, and other medical factors can also affect breath. If an oral examination does not explain the problem, medical evaluation may be appropriate.
Do not rely only on masking products
Mints and cosmetic mouthrinses may temporarily cover odor but do not correct an underlying dental or medical cause.
