Sugar and Tooth Decay: What You Need to Know


Preston Dental Saskatoon Dental Clinic Services

Many of us have been told since childhood to avoid sugary foods and drinks to prevent cavities. But just how does sugar contribute to tooth decay, and is it the only cause? In this blog, we’ll explore these questions to help you better understand the relationship between sugar and cavities.

Does Sugar Cause Cavities?

In short, yes, sugar is a major contributor to tooth decay. When we eat foods containing sugar, such as candy, soda, or even fruit juice, the sugar reacts with the bacteria in our mouths to create acid. This acid can erode the enamel on our teeth, leading to cavities over time.

It is important to note that not all sugars are created equal when it comes to tooth decay. Liquid sugars, like those found in soda or flavored coffee, tend to coat the teeth more thoroughly than other types of sugar, increasing the risk of decay. Sticky candies can also be more damaging than quickly melting options like chocolate.

Is Sugar the Only Cause of Tooth Decay?

While sugar significantly contributes to tooth decay, it’s not the only one. Carbohydrates, such as those found in bread and crackers, can also lead to acid production and plaque buildup in the mouth. Additionally, acidic foods and drinks, such as citrus fruits or sports drinks, can erode enamel over time.

How Can I Fight Cavities Before They Start?

The best way to prevent cavities is to practice good oral hygiene habits, such as brushing and flossing daily, drinking plenty of water, and visiting your dentist regularly. Your dentist may also recommend additional preventative measures, such as fluoride treatments or sealants, to help protect your teeth against decay.

Are Some Sugars Better for My Teeth Than Others?

Interestingly, some types of sugar can actually be beneficial for your teeth. Xylitol, for example, is a sugar substitute that physically prevents plaque biofilm from adhering to teeth. However, consuming too much xylitol can lead to gastrointestinal discomfort.

In general, it’s best to limit your intake of all types of sugar to prevent tooth decay. And don’t forget that even “sugar-free” foods and drinks can contribute to acid production and plaque buildup in the mouth.

In Conclusion

While sugar is a major contributor to tooth decay, it’s not the only cause. Practicing good oral hygiene habits and limiting your intake of sugary and acidic foods can go a long way in preventing cavities. And if you indulge in sweets, brush and floss afterward to minimize the damage to your teeth.
