Introduction

Dental caries, commonly known as tooth decay, is one of the most prevalent oral health conditions worldwide. It develops gradually when bacteria in dental plaque break down sugars in the mouth, producing acids that damage tooth enamel. If left untreated, it can lead to pain, infection, and tooth loss.

What Is Dental Caries?

Dental caries is a chronic disease that affects the hard tissues of the teeth. It occurs when plaque—a sticky layer of bacteria—accumulates on tooth surfaces and converts dietary sugars into acids. Over time, these acids dissolve the tooth enamel and create cavities.

Free sugars include all sugars added to foods and drinks by manufacturers, cooks, or consumers, as well as naturally occurring sugars found in honey, syrups, and fruit juices.

Causes of Tooth Decay

Several factors contribute to the development of dental caries:

  • Frequent consumption of sugary foods and beverages
  • Poor oral hygiene practices (inadequate toothbrushing and flossing)
  • Low exposure to fluoride (from toothpaste or water sources)
  • Plaque buildup on teeth over time

These factors increase acid production in the mouth, which weakens and destroys tooth enamel.

Symptoms of Dental Caries

Early-stage tooth decay may not show visible signs. As it progresses, symptoms may include:

  • Tooth sensitivity to hot, cold, or sweet foods
  • Visible holes or dark spots on teeth
  • Toothache or persistent pain
  • Swelling or infection in severe cases

Complications

If not treated early, dental caries can lead to serious complications such as:

  • Deep tooth decay
  • Dental abscess (infection)
  • Severe pain and discomfort
  • Tooth loss

Prevention of Tooth Decay

Dental caries is largely preventable with proper care:

  • Brush teeth twice daily with fluoride toothpaste
  • Limit intake of sugary foods and drinks
  • Maintain regular dental check-ups
  • Use dental floss to remove plaque between teeth
  • Ensure adequate fluoride exposure

Conclusion

Dental caries is a preventable condition that can significantly impact oral health if ignored. Maintaining good oral hygiene, reducing sugar intake, and visiting a dentist regularly are key steps in protecting your teeth from decay.
