Anyone planning on romance this Valentine's Day might want to check their breath.

According to the Irish Dental Association (IDA), one in four people suffer from halitosis (chronic bad breath), however many of these do not realise they have it.

"Often people are not aware that they are suffering from this condition and of course if that is the case they don't bother seeking treatment. Not alone can it cause major embarrassment and disappointment for people on big dates, but it can also be a sign of gum disease. If you think this may be the case for a friend or family member you should mention it to them privately. You will be doing them a favour dentally and socially," commented Dr Sean Malone, president of the IDA.

He noted that while men and women are affected equally by halitosis, women tend to seek treatment quicker than men. However, the condition is usually easy to treat.

While there has been an increase in halitosis in recent years, the IDA believes that this is largely due to new diet plans and the fact that people are keeping their own teeth for longer. This is because natural teeth provide a better breeding ground for bacteria than dentures.

As there are around 500 different types of bacteria found in a typical healthy mouth, it is essential that a build-up of bad bacteria is not allowed.

"If you want to avoid a discussion about good versus bad bacteria over that special candlelit dinner, the best thing you can do is brush your teeth twice a day, floss once a day, drink plenty of water, use mouth rinse and avoid trigger foods such as garlic and onions. Smoking is clearly bad for your health but also for your breath, as is alcohol and coffee," Dr Malone said.

He pointed out that if the problem persists, you should visit your dentist, as halitosis can be a sign of an underlying condition.

"Some 80% of all Irish adults qualify for a free annual examination, so if concerned, just make an appointment," Dr Malone added.
