What is the relationship between our diet and dental health?

Many parents often worry that their children eat junk food which may hurt their digestive system and health. Young people fear that the sugary drinks and coffee they drink can lead to obesity and pimples.

But people fail to realize that whatever we eat has a significant impact on our dental health. Anything that we eat or drink first comes in contact with our mouth and teeth and harms them much before they can damage the body. Not only the food we eat but even the time we eat them affects the wellbeing of our teeth and mouth.

How does sugary food affect our dental health?

A thin layer of dental plaque keeps developing on the surface of our teeth. When we eat sugary food, the sugar sticks to the surface of the tooth and the bacteria present in dental plaque feeds on the sugar, producing acids that lead to tooth decay and periodontal diseases. The acids produced by bacteria can attack the teeth even after twenty minutes of eating sugary food. This is the reason we should avoid sweet food like aerated drinks, jam, pie, candies, chocolate and other foods that are high in sugar.

Is snacking bad for health?

Dentists believe that having three meals is much better than snacking throughout the day. A chocolate cake that is eaten at mealtime as a dessert causes less harm to the teeth than a midday snack of chocolate cake. Food eaten at meal time is less harmful to the teeth and mouth because we salivate more at meal times. Saliva washes away leftover food in the mouth, it also neutralizes the effect of harmful acids made by bacteria. Dr. Roman Fedorciw, a Rocky Hill dentist, advises that if we cannot stop snacking, then we can at least opt for healthier snacks like almonds, nuts, apple, etc.
