Lifestyle modifications recommended for patients experiencing dry mouth to alleviate symptoms include:

  • Encourage regular oral hygiene practices such as brushing teeth twice daily with a soft toothbrush and fluoride toothpaste, tongue cleaning, and good denture care to maintain oral moisture and prevent complications .
  • Increase fluid intake with frequent sips of cold, unsweetened drinks, water sprays, ice cubes, or ice lollies to stimulate saliva and soothe dryness .
  • Use sugar-free chewing gum, boiled sweets, pastilles, or mints to promote saliva production .
  • Avoid acidic foods (e.g., pineapple) or acidic artificial saliva products if the patient has natural teeth, as these can increase tooth decay risk in dry mouth .
  • Apply lip lubricants such as petroleum jelly (Vaseline®) or water-soluble lubricants (e.g., K-Y Jelly® if on oxygen) to prevent lip dryness and cracking .
  • Modify diet to exclude irritants such as garlic and onions that may exacerbate oral discomfort .
  • Advise smoking cessation to reduce oral dryness and improve overall oral health .
  • Rinse the mouth after meals and at bedtime with warm water or appropriate mouthwash (e.g., chlorhexidine if gum disease is present) to remove debris and maintain moisture .

If symptoms persist, consider topical saliva stimulants or artificial saliva substitutes, noting patient preferences and cultural considerations regarding product ingredients .
