Bad breath is a sign of an unhealthy body?

Bad breath is common among adults, and it is a dating deal-breaker for many! According to the American Dental Association, at least 50% of adults suffer from bad breath or chronic bad breath (AKA Halitosis). There are various reasons why adults have bad breath but 90% of bad breath comes from a dirty tongue, a problem that could easily be solved via the use of a tongue scraper. However, other factors such as poor dental health habits and other potential health problems can also result in bad breath. While at first glance bad breath is a simple and treatable condition, those who suffer from Halitosis can be indicative of serious ailments like diabetes and kidney disease. Read more to find out…

Did you know that 43% out of 5,000 respondents agreed that fresh breath matters the most when it comes to a potential date? The numbers have spoken and although it sounds a bit silly, this is no laughing matter. Bad breaths might just be the reason why you are not getting that second date.

What causes bad breath?


The main cause of bad breath is bacteria that produce Volatile Sulphur Compounds (VSCs). VSCs are the main cause of what makes the breath smell bad. The type of bacteria that produces VSCs are mainly Gram-negative anaerobic bacteria. Anaerobic bacteria thrive in low oxygen regions and are commonly found where tartar build-up is excessive or in deep gum pockets.

A quick measurement of your gum pocket is indicative of the severity of your gum disease. This is because gum pockets create the perfect environment for anaerobic bacteria to thrive in. In terms of gum measurement, 2-4mm is considered normal, however, anything deeper than 5mm of gum pocketing with bleeding is indicative of a high accumulation of anaerobic bacteria that results in gum inflammation leading to possible bone loss. These harmful bacteria also produce toxins that enter the bloodstream and are also associated with other health concerns, such as diabetes, heart disease and stress. These are often the same bacteria that cause bad breath.

Bad breath can be caused by other factors too, such as food intake. When you go on a dinner date, watch out for food containing garlic and onions. These foods produce several sulfur-containing gases that are absorbed into our bloodstream, meaning our body would also exude an unpleasant odour. Tobacco products are perhaps the most notorious when it comes to bad breath as it dries up the fluids in our mouth that help wash away food stains and bacteria lingering inside.

Poor dental hygiene such as not brushing the teeth correctly, or not brushing at all, would also cause bad breath and gum disease. About 15% of bad breath may not be directly related to the mouth. It could be a result of upper and lower respiratory infection or a systemic illness such as diabetes or disorders of the kidney or liver.

The medical condition xerostomia (dry mouth in layman’s terms) can also cause bad breath. Saliva is necessary to moisten the mouth, as it helps prevent tooth decay and neutralise acids produced by plaque. It also washes away dead cells that accumulate on the tongue, gums, and throat; if not removed, these cells will decompose and can cause bad breath. Dry mouth could be caused by a number of factors such as medication or continuous breathing through the mouth, to which we would further elaborate.

5 Tips to eliminate bad breath

1) Correct mouth breathing

1) Correct mouth breathing

According to a study, breathing through the mouth is much more harmful than breathing through the nose. Mouth breathing causes the saliva in your mouth to dry up faster. Bacteria then easily multiply and thrive in a dry environment. People who sleep through the night while breathing through their mouth would experience dry mouth in the morning, and subsequently, would experience bad breath. So, breathe the right way — always through the nose. Proper nasal breathing will reduce the number of harmful particles entering your lungs and also improve the efficiency of oxygen transfer from your blood to your cells.

2) Maintain good gum health

2) Maintain good gum health

It is indeed important to practise good dental hygiene such as flossing the teeth regularly and brushing at least twice a day. However, it is equally crucial to keep our gums healthy. To do this, you can visit your dentist regularly for general maintenance of your gums. And if needed, deep cleaning with laser disinfection to reduce the anaerobic bacteria in the mouth.

3) Consume probiotics

3) Consume probiotics

Lactobacillus probiotics or “good bacteria” aids in digestion and makes the process of food and medication breakdown easier. It is known that oral administration of Lactobacillus improves bad breath and provides additional benefits that greatly improve your body’s health. Foods that contain Lactobacillus probiotics are yoghurt, miso soup and kimchi, just to name a few.

4) Drink plenty of water


4) Drink plenty of water

Besides preventing dry mouth, water, much like saliva, helps wash away food particles and bacteria in the mouth that causes bad breath. Furthermore, drinking water would also stimulate saliva secretion in the mouth, allowing the mouth to stay moist for longer periods of time.

5) Visit your dentist regularly

5) Visit your dentist

Be sure to see your dentist every 6 months to have your gums and teeth checked. Through professional help, any sign of anomalies would be detected and this could prevent any severe oral illnesses in the future.

Dear Patients, Family and Friends,

We have some great news to share!  Effective from October 1st 2022,  Coast Dental did a merger with DP Dental group!  We will be operating our new clinic under the name of DP Coast at 451 Joo Chiat Road #02-01/03, Katong Point (above Little Farms) from March 4th 2023.

My wife Shaheeda and I started Coast Dental in 2014. Prior to that I had worked in the government service and several reputable private clinics for about 7 years.  Interestingly, the first dental private practice I had worked with was DP Dental Pte Ltd where I worked for about two and a half years.

Shaheeda and I would like to take this opportunity to thank all our patients for your continual support and trust in our clinic.  We started the clinic in 2014 in a humble shophouse. We had to slowly build our reputation and branding.  With hard work and dedication, we expanded the clinic in 2017 to incorporate Myofunctional Therapy for children at Coast Kids.  Our clinic also invested in several high technology equipments during the COVID pandemic and the clinic has thrived since as we slowly navigate beyond the pandemic.

Now the next level of expansion is to consolidate our resources with a highly reputable group such as DP Dental to leverage on their expertise, human resource and management capabilities.

This will enable us to provide an even higher level of dental care.   DP Dental group has also  invested in several other initiatives to provide holistic dental care and whole body wellness.

DP Healthverse is an ecosystem of companies that have been formed by DP Dental to focus on whole body wellness.  This ecosystem comprises of

  1. i) Avantir Wellness - A state of the art wellness facility where whole body rejuvenation can take place.
  2. ii) DP Academy which focuses on learning the latest dental techniques and leveraging on technology to provide the highest level of dental care
  3. iii) Progressive Practice which facilitates the procurement of the very best dental materials and equipment from around the world.
  4. iv) DP Dental @Kovan and DP Dental @Orchard - Centres for advanced dentistry

As such it is my pleasure to embark on this exciting journey with Dr Yue Weng Cheu and his wife Louisa Lee who are the directors of DP Healthverse and DP Dental group to form DP Coast.  Together  we will continue to strive to provide dental excellence to all our patients.  Looking forward to seeing you at DP Coast!
