What Causes a Cavity?




















Did you know that only about one percent of the population is immune to tooth decay? For the vast majority of us, developing a cavity is a common problem. Of course, we don’t always understand why we suffer from tooth decay or what we can do to prevent this issue. At A New Smile Dental Group, our dental experts discuss the common factors behind cavities.

The Causes and Symptoms of Tooth Decay

Our teeth are coated in a thin but powerful layer of enamel. Tooth enamel acts as a barrier, safeguarding our smile against harmful bacteria. A cavity forms when this layer is weakened, exposing the more sensitive inner structure to bacteria. A variety of factors can cause enamel to erode, including:

  • Consuming foods and drinks high in sugar and other starches
  • Not brushing or flossing properly or often enough
  • Not enough access to fluoride
  • Smoking or using tobacco products
  • Dry mouth

If you do develop a cavity, you may not notice until your teeth become sensitive to cold or hot temperatures. Eventually, you may experience a toothache. Over time, the cavity continues to grow, potentially leading to an infection that requires a root canal procedure or even extraction to address. You should always see the dentist when you experience tooth sensitivity or a toothache.

Repairing a Cavity

How do you fix a cavity? The most common solution involves a dental filling. Made from either amalgam (metal) or composite resin, fillings repair the decayed portion of the tooth. First, we will remove the decay and thoroughly clean the tooth. A filling material will then be added and cured with a special light. Once complete, your tooth will be protected against further decay. Most patients prefer the composite fillings, which can be shaded to blend seamlessly with the tooth structure.
