The Importance of Saliva in Oral Health

Let's talk about saliva. Did you know that this underrated bodily fluid is a superhero for your oral health? In fact, it plays several crucial roles in keeping our mouths healthy and happy.

One of the most important functions of saliva is to keep our mouth moist. Experiencing dry mouth at night can be uncomfortable and even lead to bad breath, mouth sores, and tooth decay.

Chewing sugar-free gum or sucking on sugar-free candy can also help.

Saliva production can also be affected by health conditions or side effects of medication. In these cases, artificial saliva or saliva substitutes may be recommended by a healthcare professional.

Saliva also helps to neutralize acids produced by bacteria in our mouths, which can cause tooth decay. It contains enzymes that aid in digestion and helps to wash away food particles and debris. Saliva even helps to prevent dry eyes by keeping our eyes moist.

For those with sleep apnea or continuous positive airway pressure (CPAP) machines, dry mouth can be a common side effect. To reduce dry mouth, try using a humidifier in your bedroom or using a nasal spray to clear nasal passages and reduce nasal congestion.

If you suspect any of these issues may be affecting your oral health or if you're experiencing persistent nighttime dry mouth despite trying various remedies, it's essential that you consult with a healthcare professional like your doctor or dentist for further evaluation and guidance on appropriate treatments.
