Let’s Talk: Tooth Decay

When people hear the word cavity, they often imagine a visible hole in a tooth. In reality, tooth decay—also called dental caries—usually begins long before anything can be seen or felt. At its earliest stage, decay simply means the tooth has lost important minerals and become weakened or softened.

The good news is that when cavities are caught early, teeth can often be strengthened through remineralization or repaired with very small, conservative fillings. Early care helps preserve more of your natural tooth and keeps your smile healthier in the long term.

What actually causes tooth decay?

Your mouth is home to billions of bacteria. These bacteria feed on sugars from the foods and drinks we consume and produce acid as a byproduct. Over time, this acid pulls minerals from the tooth surface, weakening it. Saliva plays a crucial protective role by neutralizing acid and helping replace lost minerals—but when this balance is disrupted, decay can develop.

Factors such as frequent sugary snacks or drinks, inadequate oral hygiene, dry mouth, and even genetics can increase the risk of cavities.

One important thing to remember: by the time a tooth hurts, decay is often already advanced. Cavities don’t always cause pain in their early stages, so a lack of symptoms doesn’t necessarily mean your teeth are problem-free. Treating decay early allows dentists to restore teeth more conservatively and helps maintain their strength for years to come.

What can you do to prevent tooth decay?

• Practice good daily habits, including brushing twice a day and flossing before bed.
  
• Use a fluoride mouth rinse, especially if you are at higher risk for cavities
  
• Be mindful of sugar intake. Drinks are often the biggest culprit, including juice, pop, coffee or tea with sugar, sports drinks, and alcoholic beverages. Keep in mind that time of exposure matters more than the amount of sugar. Slowly sipping a sugary coffee over three hours is far worse than drinking the same cup in 30 minutes. Watch out for sticky candies, such as gummies, which can also increase risk
  
• Schedule regular dental checkups and cleanings. Early intervention is key to keeping your smile healthy and bright!
