The outermost shield safeguarding one’s teeth is known as enamel. Tooth decay happens when this protective layer is compromised, exposing the underlying layers of teeth. Preserving the longevity of enamel requires diligent oral hygiene practices, but a significant contributor to tooth decay is the food one eats. While enamel erosion is a natural part of aging, certain foods can expedite this process. Here are some harmful foods that should be avoided to protect one’s teeth.

1. Sweets
   There are millions of good and bad bacteria in one’s mouth. Consuming foods rich in sugar, like table sugar, candies, cakes, donuts, sugary breakfast cereals, and the like, provides a feeding ground for harmful bacteria. These bad bacteria convert the sugar into corrosive acids, which slowly strip essential minerals from the teeth and lead to cavities. So, one should avoid excessive intake of sugary snacks and practice good oral hygiene practices to protect one’s teeth.
2. Chips, white bread, and crackers
   Starchy foods like potato chips, crackers, and white bread may not seem harmful at first glance, but they can pose a threat to dental health. When the starch in these foods breaks down, it converts into sugar that feeds bad oral bacteria. Additionally, starchy foods can become lodged between teeth, promoting bacterial growth and increasing the risk of cavities.
3. Caramel and sticky foods
   Foods that are sticky or chewy can wreak havoc on teeth. Sticky substances like caramel, toffee, and certain dried fruits like apricots, prunes, figs, and raisins cling to the teeth and crevices and create an environment conducive to bacterial growth. This can, in turn, lead to the formation of plaque, a thin film on the teeth that expedites acidity and gives rise to more serious dental issues.
4. Citric fruits
   Citric fruits like grapes, pineapples, gooseberries, lemons, and oranges contain high levels of acid, which can make one’s teeth susceptible to decay. So, it’s best to eat them in moderation, during meals, and rinse the mouth thoroughly after consumption to maintain teeth integrity.
5. Ice pops
   Frozen treats like fruit pops made of citric fruits can significantly reduce the salivary pH balance compared to their juices at room temperature. Essentially, these ice pops have even higher acidity than direct citric fruits, so it’s important to limit their consumption or opt for whole fruits in moderation for better oral health.
6. Nuts and hard food
   Indulging in hard foods can lead to cracked or chipped teeth and increase the wear of enamel. Foods like hard candies, hard pretzels, popcorn kernels, and nuts can place undue stress on teeth, particularly if one bites them down forcefully. So, dentists often caution against regularly eating such hard foods.
7. Carbonated drinks
   Carbonated drinks, including sodas and sparkling water, pose a dual threat to dental health. They not just contain high levels of sugar for taste enhancement, but the carbonation itself can be harmful. Carbonated beverages are acidic in nature, and regular consumption of these can contribute to enamel erosion and compromise the integrity of teeth.

Maintaining good oral hygiene goes beyond regular brushing and flossing; it requires a mindful approach to food choices. Foods that harm teeth are often disguised as everyday indulgences, and being aware of their impact is essential for maintaining optimal dental health.
