Traditionally, the number of teeth a person has was seen as an indicator of health. But this study went further. Instead of merely counting teeth, researchers classified each tooth as either sound, filled, or decayed. They discovered that older adults with more healthy or treated teeth had a significantly lower risk of death during the study period. In contrast, those who had lost all their teeth faced about 1.7 times higher mortality risk compared to people with 21 or more functional teeth.
Interestingly, including decayed teeth in the analysis reduced the accuracy of health predictions. Simply put, untreated decay not only affects your mouth—it can reflect underlying health risks as well.
Drinks That Can Harm Teeth from the Inside Out
Enamel, the protective outer layer of your teeth, does not regenerate. Frequent exposure to sugar and acids can wear it down, sometimes long before cavities appear on X-rays. Here are six common drinks that can slowly damage teeth if consumed regularly, along with why they’re risky:
1. Energy and Sports Drinks
Often seen as performance enhancers, these beverages are surprisingly harsh on teeth. Packed with sugar and acids, they can erode enamel even faster than soda. Sipping them slowly during workouts or study sessions prolongs acid exposure, leaving teeth vulnerable to decay.
2.Coffee and Tea
On their own, coffee and tea are mildly acidic but generally less harmful than sodas. The real problem arises when sugar, flavored syrups, or milk are added. These drinks can stain softened enamel and create a cavity-friendly environment, especially when sipped throughout the day.
3. Flavored and Sparkling Water
While plain water is excellent for oral health, flavored or carbonated options can be more damaging than they seem. Carbonation produces carbonic acid, and added citrus flavors increase acidity, which over time can contribute to enamel erosion if consumed frequently.
4.Fruit Juices and Drinks
Even natural fruit juices, including orange, grape, lemon, and berry varieties, are high in sugar and acids. Drinking juice in large quantities exposes teeth to concentrated acid, which can thin enamel and increase the risk of cavities. Unlike whole fruits, juice lacks fiber, making it easier for acids to attack the teeth.
5. Regular Soft Drinks
Traditional colas and fizzy drinks are a double threat: they contain sugar and acids like phosphoric and citric acid. Constant sipping keeps teeth bathed in an acidic environment, leading to surface wear, sensitivity, yellowing, and overall enamel erosion.
6. Diet and Zero-Sugar Sodas
Even without sugar, diet sodas remain highly acidic. Phosphoric, citric, and carbonic acids continue to weaken enamel, increasing susceptibility to wear and cavities from other foods. Switching to diet doesn’t protect your teeth from acid-related damage.
Your teeth are more than just tools for chewing—they’re indicators of your general health. Keeping them strong and healthy involves more than brushing; it requires paying attention to what you drink every day. Limiting acidic and sugary beverages, practicing good oral hygiene, and getting regular dental check-ups can help preserve enamel and reduce health risks over time. Healthy teeth don’t just make you smile—they may help you live longer.
