Dry Mouth: Understanding the Risks

Dry mouth refers to a lack of saliva inside the mouth. Since saliva plays an important role in oral health, it is essential to understand the risks linked to this condition. Below, we explain these risks, the causes of dry mouth, and the available solutions to manage it.

The Important Role of Saliva

Saliva plays several roles within the oral environment and helps protect the teeth and gums from bacteria.

First, saliva lubricates the oral tissues and allows us to speak comfortably. When mixed with food during chewing, saliva forms what is called the food bolus. This is the first step of digestion, allowing us to swallow food properly.

Saliva also performs important functions that protect the teeth. It neutralizes acids from food and those produced by bacteria when they feed on sugary residues. By helping restore the mouth’s pH level after eating, saliva helps prevent cavities. It also helps prevent enamel erosion caused by an overly acidic oral environment.

Consequences Associated With Dry Mouth

Based on the information above, you may already guess the potential consequences of dry mouth. Here they are:

• Increased risk of premature enamel wear (the protective layer of the teeth)
• Higher risk of developing cavities or gum disease, as oral bacteria become more active
• Difficulties with speech, chewing, and swallowing
• Higher risk of mouth ulcers or injuries inside the mouth
• Chronic bad breath, as bacteria release volatile compounds that create unpleasant odors

How to Manage Dry Mouth

A sticky mouth, dry throat, discomfort… These are clear signs of dry mouth. It is important to discuss them with your dentist to find solutions. Certain habits and strategies can help manage this condition. Here are some tips from our dentists:

• Chew sugar-free gum: chewing stimulates saliva production. Choose sugar-free gum to avoid increasing the risk of cavities.
• Drink plenty of water: at least two liters of water per day helps maintain good hydration and reduces dry mouth symptoms.
• Review your medication list: many medications reduce saliva production as a side effect. Review your medication list with a doctor or pharmacist to explore alternatives.
• Avoid certain drinks: beverages that contain caffeine and alcoholic drinks can contribute to dehydration. Spicy foods can have the same effect.
• Be mindful of mouth breathing: breathing through the mouth can significantly dry out oral tissues. It is important to breathe through the nose with the mouth closed.

If lifestyle changes are not enough to manage dry mouth, your dentist may recommend treatments such as lubricating gels or mouth rinses. Discuss it during your next routine visit to prevent the negative effects associated with this condition.
