Tooth decay, a common dental issue, arises from several factors that compromise oral health. First, poor oral hygiene is a leading cause. When individuals neglect to brush and floss regularly, plaque builds up on the teeth, creating an environment where harmful bacteria thrive and produce acids that erode enamel. Second, consuming sugary and acidic foods and drinks promotes decay. Sugars provide fuel for bacteria, while acidic items weaken enamel directly, leaving teeth more vulnerable to cavities.
A third cause is the lack of fluoride, a mineral that strengthens enamel and helps teeth resist decay. Without adequate fluoride, from water sources or dental products, enamel remains weak and susceptible to bacterial attacks. Fourth, dry mouth conditions, or xerostomia, reduce saliva production. Saliva plays a critical role in neutralizing acids and washing away food particles. When saliva is insufficient, acids linger longer, causing more harm.
Lastly, underlying health issues, such as diabetes or acid reflux, can contribute to decay. Diabetes, for instance, can lead to higher glucose levels in saliva, feeding harmful bacteria, while acid reflux exposes teeth to stomach acids, eroding enamel. Addressing these factors through diet, hygiene, and medical care is essential to prevent tooth decay.
