Bad Breath: How to Know and Fix It

Civil society depends in some measure upon the things which its members agree not to say. A crooked tie may be corrected by a friend without much ceremony; an unpleasant breath is more often met by a slight increase in conversational distance, the reason for which its owner is left to discover for himself.

One’s own nose is a poor judge because it quickly grows accustomed to familiar odours. Wrist tests and similar domestic experiments are unreliable. A candid companion, dentist, or hygienist can give a more useful answer.

The common causes are usually manageable through ordinary hygiene, beginning with a part of the mouth which many men overlook. The tongue retains a considerable deposit, and should be cleaned when the teeth are brushed; a tongue scraper does the work more thoroughly. I remember the tortoiseshell implement, though the surgical-steel article now sold is easier to clean and answers just as well.

The spaces between the teeth also require daily attention. In my youth waxed silk thread was used; the thin synthetic ribbons now available are easier to manage, and there can be little excuse for leaving food to decay where the brush and mouthwash cannot reach it.

Drink water throughout the day. Dry mouth makes odour more likely and may be caused by medication, tobacco, mouth breathing, dehydration, or illness. Coffee and alcohol can make dryness or odour more noticeable in some people.

When the difficulty persists despite careful brushing, cleaning between the teeth, cleaning the tongue, and adequate water, make an appointment with a dentist. Do not wait where there is pain, bleeding, swelling, a sore which does not heal, loose teeth, or marked dryness. Persistent halitosis may accompany decay or disease of the gums and should be placed before a professional.
