Has dental health improved in Chile?
Yes, there have been advances, thanks to greater education and awareness of the importance of oral health among the population, and to increased public investment in oral health through programs for FONASA (public health) beneficiaries. Although the prevalence of cavities has decreased, the population still perceives its oral health as fair or poor. Socio-economic factors continue to limit access to treatment and education, so the improvement is partial and still insufficient. To this, new oral diseases are added, such as lesions caused by bruxism and erosive wear, which are associated with the current lifestyle and lead to significant dental wear and sensitivity.
In addition to good hygiene, what other factors favor the health of our teeth?
Along with hygiene, which should include brushing and flossing, the use of fluoride in mouthwashes or toothpastes is beneficial, as it strengthens teeth. A balanced diet, low in sugars and rich in anti-cariogenic foods, such as peanuts, fish, tea, proteins, and fats; maintaining good hydration to promote salivary flow and regular dental check-ups to detect and treat early lesions. It is key to avoid bad habits, such as tobacco and alcohol, acidic foods and drinks, such as energy drinks, hot water with lemon, excessive brushing or with very abrasive toothpastes, biting our nails or chewing on pencils, or opening containers with our teeth.
What myths about dental issues remain ingrained in society?
Some myths are “Brushing hard or many times a day cleans better”: False. Brushing too hard wears away enamel and damages gums; the correct approach is to use a soft-bristle brush, use a proper technique, and brush up to three times a day. “If it doesn’t hurt, there is no disease”: False. Cavities, gum disease, erosive wear and tear, or microfractures do not hurt at first, until they are advanced. “Rinsing, apples or sugar-free chewing gum replaces brushing”: False. Brushing and flossing help sweep bacteria properly throughout the tooth. Finally, self-medication or the use of home remedies such as baking soda, lemon juice, or brine can wear down enamel and cause sensitivity.
