Ever Wondered If You Have Bad Breath? A New Sensor Can Tell You

Bad breath is a common, yet difficult thing to live with, and many of us worry about having bad breath throughout the day. Practicing excellent oral hygiene is the best way to combat bad breath. However, new research shows that a thumb-sized sensor could help detect bad breath for you!

Bad breath is a common source of concern, anxiety and embarrassment. It is one of those topics that is difficult to ask others for an honest opinion about, and even more difficult to tell someone about their bad breath.

But recent research that has focused on studying ways of detecting bad breath has found that a specially-constructed, thumb-sized device could allow us to automatically detect if we have bad breath.

Finding an accurate method to detect bad breath has been a topic of interest for a long time for researchers, especially given how common the issue of bad breath is for people around the world. Therefore, this is an exciting development.

What is bad breath?

Many people have bad breath now and then, while others have long-term problems with bad breath – which is a medical condition called Halitosis.

Bad breath affects many people, with statistics suggesting approximately 60million people in the United States alone suffer from chronic halitosis [1].

Bad breath is linked to the levels of a gas named hydrogen sulfide that is present in our mouths. This is the gas that causes bad breath.

From a dental perspective, persistent bad breath is often a sign of halitosis or gum disease, and therefore early identification can be very helpful in preventing worsening oral health.

Aside from physical health, bad breath can also be a problem socially. A study in the United Kingdom found that bad breath was the “biggest turn off” for people looking for a new partner [2]. Bad breath can also negatively impact mental health, with low self-esteem and anxiety commonly associated with those who have bad breath [3].

The causes of bad breath

Poor oral hygiene is the most common cause of bad breath. Toothpaste not only effectively cleans the mouth, but it also leaves a minty taste behind, keeping our breath fresh and pleasant.

But when people avoid brushing their teeth, neglecting to floss, and ignoring their tongue, it results in the build-up of bacteria in and between the teeth and gums, which leads to rotten-smelling gases to emit.

Aside from poor oral hygiene, other common causes of bad breath or halitosis include foods, diseases and tobacco.

Many things cause short-term bad breath, such as strong-flavoured foods like garlic and onions. But others, like smoking, can cause both short and long-term breath quality problems. Smoking also stains teeth and irritates gums [4].

Certain medications and medical conditions are also linked to bad breath. Dry mouth, some gastrointestinal conditions and even diabetes can all worsen breath [5].

The Research

There has been significant research in the past into ways of detecting bad breath. But while some devices already exist, their accuracy and legitimacy has been questioned. These devices also require exhaled air to be tested on expensive scientific equipment, therefore making it impractical for general public use.

But thanks to a new study, this could change. The recent research was published in the ACS Nano journal, and was carried out by researchers at the South Korea-based Advanced Institute of Science and Technology [6].

The researchers have been able to create a new sensor that is able to detect the levels of hydrogen sulfide in breath – which, as mentioned earlier, is the gas that leads to bad breath.

The researchers created a solution, which consisted of different levels of sodium chloride, metal salt, platinum metal nanoparticles and tungsten. The solution was then manufactured into tiny fibres using a technique called electrospinning [6].

Researchers used different solutions and quantities of chemicals in order to find the most effective final solution, which was measured by the solution with the highest reactivity to hydrogen sulfide.

The sensor would combine with the above solution to detect levels of gas, temperature, pressure and humidity, in order to ascertain breath quality.

When tested, the sensor was able to identify bad breath 86% of the time when measuring exhaled air. The researchers suggested that a process of filtering would lead to even more accurate results [6].

As a result of these findings, the researchers have suggested that a small, thumb-sized device could soon be built, which could be sold to the general public – providing them with rapid results on the quality of their breath [6].

What we offer at Savanna Dental

Here at Savanna Dental, we are happy to offer our patients a vast range of services. We are based in a convenient location within Calgary, Alberta, Canada.

We strive for patient satisfaction, and ensure that we provide our visitors with a comfortable, caring and reassuring experience.

We discussed earlier about how bad breath can be a sign of health problems, and this is consistent with any oral health issues – it is important to attend regular check-ups to check overall oral health.

The earlier that any problems are detected, the better the chance of recovery. We therefore recommend that our patients see us at Savanna Dental at least twice a year for a regular check-up.

If further treatment is required following a dental check-up, we provide our patients with a clear treatment plan, whilst giving them a voice in their treatment.

Just some of the many services we offer include cavity fillings, root canals, dentures, and even cosmetic dentistry services like teeth whitening.

The best thing we can all do to avoid extra treatment is to practice excellent oral hygiene. This includes brushing our teeth at least twice a day, flossing regularly, and potentially using a tongue scraper – with this helping to protect against bad breath.

Avoiding smoking, sugary foods and drink and alcohol wherever possible can also protect our oral health.

Our Calgary dental clinic Savanna Dental also follows the Alberta Dental Fee Guide, which provides affordable and totally transparent fees.

Summary

Recent studies certainly suggest that dental health is going to be aided by technological advancements. As well as this bad breath device, other recent developments include the possibility of predicting tooth loss, and even a candy that could lead to enamel restoration (click here to know more).

The study above into bad breath is another example of exciting developments being made in dentistry. However, for now, the focus must remain on practicing excellent oral hygiene.

That is the best way of staving off the threat of bad breath, and also helps to fight against dental problems.

We hope that you visit our Calgary-based dental clinic Savanna Dental soon! You can visit our website by clicking here https://savannadentalclinic.ca, where you can find out more about us, and the various services that we offer our patients.
