Eating too many sweets is bad for your teeth mainly because of two main reasons:

1. Sugar Feeds Harmful Bacteria: Your mouth contains bacteria that feed on sugars present in sweet foods and drinks. When these bacteria consume sugar, they produce acids as a byproduct. The primary acid is lactic acid, which can demineralize tooth enamel, weakening it and making it susceptible to decay. This process is commonly referred to as dental caries or cavities.
2. Acid Attack on Tooth Enamel: The acids formed by the bacteria lower the pH level in your mouth, creating an acidic environment. Tooth enamel, which is the hard outer layer of the tooth, begins to dissolve at a pH below 5.5. Frequent and prolonged exposure to acidic environments caused by sugary foods increases the risk of enamel erosion and cavity formation.

Additionally, sticky or chewy sweets tend to adhere to teeth for a longer duration, prolonging the acid attack. Also, snacking frequently on sugary items instead of consuming them during meal times can increase the frequency of these acid attacks, as saliva production tends to be higher during meals, helping to neutralize acids and remineralize the teeth.

Therefore, it’s recommended to limit the consumption of sweets, brush teeth twice daily with fluoride toothpaste, floss regularly, and maintain a healthy diet that includes plenty of water and foods that promote oral health. Regular dental check-ups and cleanings are also essential to prevent tooth decay and gum disease.
