Oral health is often seen as “genetic,” yet most cavities and gum problems are strongly influenced by daily routines. The key idea is simple: throughout the day, your teeth face repeated acid attacks; effective plaque control, fluoride exposure, and smart dietary patterns reduce damage and support remineralization.\n\nThis guide summarizes evidence-based habits: brushing frequency, fluoride use, interdental cleaning, why sugar frequency matters as much as total intake, gum-supportive behaviors, and nutrients that help maintain enamel and oral tissues. If you have higher-risk conditions (bleeding gums, dry mouth, diabetes, pregnancy, orthodontics/implants), a personalized dental plan and professional assessment are recommended.
