Bad Breath From Dry Mouth And How To Treat It

We're all familiar with bad breath—pretty much everyone has it in the morning! That said, it can be embarrassing sometimes and makes us feel a little self-conscious. In most cases, we can avoid bad breath simply by practicing good oral care. Sometimes, however, bad breath is caused by other conditions like dry mouth problems, which have little to do with poor dental hygiene.

The good news is — no matter what the cause — you can take steps to identify and treat your dry mouth and bad breath and prevent these issues from recurring.

What causes mouth dryness?

Not sure what dry mouth is or what causes it? Well, there could be a variety of reasons why you're experiencing ongoing dryness in your mouth. Minor illnesses such as vomiting, mild dehydration or flu may lead to temporary mouth dryness. In some cases, dry mouth can be a symptom of a medical condition like diabetes. Mouth dryness (known as xerostomia) can also be a side effect of some medications. According to National Cancer Centre Singapore, these may include medications for allergies (antihistamines), mood (antidepressants), increasing urination (diuretics) and pain (opioids). Chemotherapy can also cause dry mouth.

What are some reasons for bad breath?

So you now know what can cause dry mouth, but you may be wondering why dry mouth causes bad breath. Interestingly, medication isn't the direct cause of bad breath. It's the chemicals within the medicine that inhibit your salivary glands from producing saliva. According to the National Institute of Dental and Craniofacial Research in the United States, saliva keeps the mouth hydrated, washes food particles away from your teeth and gums, and can help fight tooth decay. Without sufficient saliva to perform these tasks, the increased presence of bacteria in your mouth – coupled with dry oral tissues – produces the odour commonly associated with bad breath from dry mouth.

How do you diagnose dry mouth?

Understanding the real cause of your dry mouth is important and will help your doctor find the proper treatment for you. Most dental professionals can quickly determine whether the reason is related to your oral health or something else. If the diagnosis from your dentist is periodontal disease or cavities, they can help resolve these issues. However, if medication for another medical condition is the causing your dry mouth, you may need the care of a medical doctor or specialist to diagnose and address the issue.

What are treatments for dry mouth?

Even if you have dry mouth, there are steps you can take to treat it. Most patients require a two-pronged approach to treating dry mouth problems. Initially, your doctor will likely recommend treatment to manage your symptoms, ranging from dental sores to bad breath. Treatment may also include antibiotics for signs of oral infection. At the same time, your physician will investigate the cause of your dry mouth, conducting tests for any medical conditions or making adjustments to your medications and dosages.

Prevention

Of course, even before you get to the point of treatment, you might be able to find ways to prevent bad breath. If you find your medication alternatives are limited, or you have one of the medical conditions that cause xerostomia, your best method of preventing bad breath from dry mouth is to maintain a high level of oral hygiene to control bacteria and avoid the development of bad breath and mouth sores. You can always ask your doctor to recommend products specially formulated to prevent dry mouth and avoid habits such as smoking or drinking alcohol and caffeine.

So if you're experiencing bad breath due to dry mouth, whether it's due to medication or a medical condition, there are several things you can do to improve the situation. The most important thing is to find the root cause of your dry mouth. Your dentist or doctor can guide you through this process, and together, you can decide on what's the best course of action.

It's also essential to manage your stress levels and protect your overall health. Taking the time to take care of yourself is the first step towards better oral hygiene and breath. And let's face it, when we have good breath, we feel good too!
