Sugar has long been known to have negative effects on your teeth, but this was not always the case. One thing that cannot be disputed is that sugar is a major promoter of tooth decay. If you are wondering how sugar can destroy your teeth, read ahead and find out!

Your mouth is a huge battleground

Your mouth is home to a wide variety of microorganisms. Some are good for your dental health, while others are bad. For example, there is a specific strain of dangerous bacteria that produces acid in your mouth anytime they come into contact with and consume sugar. These acids dissolve minerals from your tooth enamel, which is the beautiful, protective covering on the outside of your tooth in a process known as demineralization. However, your saliva continuously helps to reverse this serious damage through a natural process known as remineralization.

Minerals in your saliva, including calcium and phosphate, as well as fluoride from toothpaste and water, aid in the restoration of enamel by replenishing minerals lost during an “acid attack.” 

This strengthens your teeth. The recurrent cycle of acid attacks, on the other hand, produces a mineral loss in the enamel. This weakens and dissolves the enamel over time, resulting in the formation of a cavity.

Sugar lowers your mouth’s PH while attracting bad bacteria

Sugar attracts harmful microorganisms like a magnet. Streptococcus mutans as well as Streptococcus sorbrinus are the two harmful bacteria present in the mouth. Both feed on the sugar you consume and build a dental plaque-a sticky, white film that grows on the surface of your teeth If plaque is not removed by saliva or brushing, the mouth gets more acidic, and cavities start forming.

 Dietary habits which may lead to tooth decay

  • Consuming snacks that are high in sugar.
  • Drinking sugary and acidic beverages.
  • Eating sticky and acidic food.

Tips to help you fight tooth decay

  • Be conscious of what you eat. Ensure that your diet contains whole grains, vegetables, and fresh fruits. Also, include dairy products in your food.
  • Reduce your intake of sugar. Sugary and sticky meals should be consumed in moderation.
  • You should ensure that you practice acceptable levels of oral hygiene.

The Bottom Line

When you drink or eat something sugary, the bacteria in your mouth starts to break it down. They do, however, produce acid as a byproduct of the process. Acid erodes tooth enamel, resulting in tooth decay over time. To combat this, limit your intake of high-sugar foods and beverages, particularly between meals and shortly before bedtime.

Taking proper care of your teeth and living a healthy lifestyle are the most effective approaches to combat tooth decay. When you consume more sugar, you increase the chances of your teeth getting spoiled. But just in case, let brushing be your friend. As soon as you complete eating or drinking anything sugary, brush right away.
