Compose a prioritized three-item clinical counseling script for an adult patient who drinks only well water (unfluoridated) and expresses concern about cavities. Which three elements, in order, best synthesize evidence-based preventive strategies?

• A. 1) Use only sea salt to flavor food because it contains fluoride; 2) avoid dental check-ups as they will often recommend unnecessary fluoride varnishes; 3) rely on chewing gum for mechanical cleaning instead of fluoride products.
• B. 1) Start drinking exclusively commercially bottled water labeled 'no minerals' for purity; 2) cease all toothbrushing to avoid fluoride exposure because it is dangerous without municipal oversight; 3) increase sugar-free beverage consumption to wash the teeth.
• C. 1) Replace well water with untreated river water for natural minerals; 2) take high-dose iodine supplements to indirectly protect teeth; 3) use non-fluoride herbal toothpaste exclusively.
• D. 1) Use fluoridated toothpaste twice daily and avoid swallowing; 2) arrange periodic professional topical fluoride treatments or discuss fluoride supplements with a dentist if caries risk is high; 3) reduce frequent sugary snacking and encourage regular dental visits.
