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.
