The Dangers of Dry Mouth: A Dentist’s Perspective on Oral Health

Although many people view dry mouth as merely an inconvenience or discomfort, it is actually a condition that we are concerned about because of its impact on oral health.   In this blog, we want to talk about how dry mouth can affect your oral health and why it’s crucial to address this issue.

First and foremost, let’s understand what dry mouth is. Also known as xerostomia, dry mouth occurs when the salivary glands fail to produce enough saliva to keep the mouth adequately moist . Saliva plays a crucial role in oral health by helping to lubricate the mouth, wash away food particles, neutralize acids, and prevent the growth of harmful bacteria. When saliva production decreases, it can lead to a host of oral health problems.

One of the most immediate effects of dry mouth is discomfort. Without enough saliva to keep the mouth with enough saliva, you may experience a persistent dry feeling, as well as difficulty chewing, swallowing, and speaking. This discomfort can significantly impact a person’s quality of life and make everyday activities such as eating and talking challenging.

The consequences of dry mouth extend beyond mere discomfort. Saliva serves as a natural defense mechanism against bacteria in the mouth. When saliva production decreases, harmful bacteria can grow, leading to an increased risk of cavities, gum disease, and other oral infections. Without the cleansing action of saliva, food particles and plaque are more likely to build up on the teeth and along the gum line, creating an environment conducive to decay and inflammation.

Saliva also plays a role in maintaining the pH balance of the mouth. When saliva production decreases, the pH level of the mouth becomes more acidic, creating an environment that is favorable to the growth of acid-loving bacteria. These bacteria produce acids that can erode tooth enamel, leading to cavities and tooth sensitivity. Over time, untreated dry mouth can contribute to tooth decay and even tooth loss.

In addition to its role in preventing cavities, saliva also aids in the remineralization of tooth enamel. Saliva contains minerals such as calcium and phosphate, which help to strengthen and repair enamel that has been damaged by acids. When saliva production is insufficient, the remineralization process is compromised, increasing the risk of enamel erosion and tooth decay.

So, what can be done to address dry mouth and protect oral health? First and foremost, it’s essential to identify and address the underlying cause of dry mouth with our dentist. Common causes include medications, medical conditions, lifestyle factors, and dehydration, so be sure to update all your medications with our hygienist when you are in the office. By addressing the root cause of dry mouth, it may be possible to alleviate symptoms and improve saliva production.

In addition to addressing the underlying cause, there are several strategies that individuals with dry mouth can use to manage their symptoms and protect their oral health. These include:

    • Stay hydrated by drinking plenty of water throughout the day.
    • Avoid or limit the consumption of alcohol, caffeine, and tobacco, all of which can contribute to dry mouth and health issues.
    • Use over-the-counter saliva substitutes or moisturizing mouthwashes to help keep the mouth moist.
    • Chew sugar-free gum or suck on sugar-free candies to stimulate saliva production.
    • Practice good oral hygiene habits, including brushing twice a day, flossing daily, and visiting the dentist regularly for check-ups and cleanings. See our how-to best floss and brush your teeth here:

  • In some cases, a dentist may recommend prescription medications or other treatments to help stimulate saliva production and alleviate symptoms of dry mouth.

Dry mouth is a common yet often overlooked condition that can have serious implications for oral health. Without adequate saliva production, individuals are at increased risk of cavities, gum disease, and other oral infections. By understanding the causes and consequences of dry mouth and taking steps to address it promptly, individuals can protect their oral health and maintain a comfortable, healthy smile for years to come.
