Bad breath: how to prevent it

With Valentine’s Day around the corner, Dr Paul O’Dwyer, group clinical advisor at Dental Care Ireland, answers some common questions on how to keep bad breath at bay

Q: What is the most common cause of bad breath?

A: Bad breath (halitosis) can often originate in the gums and tongue. It is typically caused by the bacteria in our mouths as they work to naturally break down food. Smoking is also a common cause. In some cases, persistent bad breath can also be a sign of underlying issues such as tooth decay or gum disease.

Q: Is stress a contributing factor? 

A: Stress, dieting, age, hormonal changes, and dry mouth can all exacerbate the symptoms.

Q: How can I help prevent bad breath?

A: It is important to maintain a consistent oral health routine at home. Ideally, brush twice per day for two minutes with a fluoride toothpaste. Remember to include your tongue, as it can also harbour bacteria. Floss teeth at least once a day, to help clean areas that your toothbrush cannot reach. It is best to replace your toothbrush at least every three months, or after an illness.

Q: How can I avoid it after eating my favourite foods? 

A: Strong-smelling foods and drinks, such as onions, garlic or coffee, can be detected on a person’s breath for up to 72 hours after digestion. The effect on your breath is usually only temporary. Drinking plenty of water and chewing sugar-free gum after a meal, will increase saliva flow, which helps eliminate the odour-causing bacteria.

Q: How can I manage bad breath from smoking?

A: Mouthwashes and smokers’ toothpastes may be effective in removing stains and freshening up the mouth. While they can mask the symptoms/signs of halitosis, however, they cannot treat any underlying damage caused by smoking. Smoking also irritates the gums and often contributes to your chances of tooth decay and gum disease.

Q: What should I do if my bad breath persists?

A: If your bad breath persists, it could be a sign of underlying issues including tooth decay or gum disease. Schedule a regular check-up with your dentist or dental hygienist to help maintain your oral health and prevent the occurrence of bad breath.
