Introduction

In this episode of Save Your Money, Save Your Teeth, host Eon Engelbrecht and guest Dr Clifford Yudelman explore the pervasive issue of chronic dry mouth (xerostomia). They discuss its most common causes- from dehydration and medications to autoimmune conditions and head‐and‐neck radiation - examine how reduced saliva impacts oral health and daily comfort, and share practical, evidence-based strategies for relief and long-term protection of teeth and gums.

Key Takeaways

Major Causes of Dry Mouth

• Dehydration: Inadequate fluid intake, excess caffeine or alcohol.
• Medications: Antihypertensives, antidepressants, antihistamines, diuretics.
• Autoimmune Disorders: Sjögren’s syndrome directly damages salivary glands.
• Radiation Therapy: Head/neck irradiation can destroy saliva-producing tissue.

Oral Health Consequences

• Increased risk of cavities (caries) due to loss of saliva’s buffering and remineralising functions.
• Difficulty speaking, chewing and swallowing; higher incidence of oral infections such as candidiasis.
• Mucosal discomfort (“burning mouth”) and denture retention problems.

Diagnostic Approaches

• Thorough medical and medication history review.
• Simple clinical tests: unstimulated saliva observation (lip dryness test) and stimulated saliva collection.
• Referral for specialist tests (salivary flow measurement, lab panels, imaging) when underlying disease is suspected

Everyday Triggers to Avoid

• Alcohol-based mouthwashes and tobacco use.
• Excessive caffeine and energy drinks.
• Mouth-breathing (especially at night), sugary or acidic snacks.

At-Home Relief Strategies

• Hydration: Frequent sips of water or saliva sprays.
• Ice Chips: Slow sucking of crushed ice.
• Xylitol Gum: Sugar-free gum stimulates residual saliva flow.
• OTC Saliva Substitutes: Gels and sprays that mimic natural saliva.
• Humidifiers: Adding moisture to bedroom air, especially for CPAP users.

Professional & In-Office Therapies

• Custom trays with remineralising gels (e.g., Tooth Mousse) for nightly use.
• Prescription sialogogues (e.g., pilocarpine) via specialist referral.
• Photobiomodulation (low-level laser therapy) to stimulate gland function.
• Emerging treatments: platelet-rich fibrin (PRF) injections into salivary glands.

Protecting Teeth & Gums Long-Term

• Twice-daily brushing with fluoride toothpaste (and minimal rinsing).
• Regular application of high-fluoride varnish or glass-ionomer sealants.
• Professional cleanings and check-ups at three-month intervals for high-risk patients.
• Annual medication reviews with a general practitioner to mitigate drug-induced dryness.
