What Causes Cavities? The Science Behind Tooth Decay



Cavities, or tooth decay, are one of the most common dental issues that plague people of all ages. While many may think cavities are caused by eating too much sugar and not brushing enough, the truth is a bit more complex. In this article we will explore what actually causes cavities and how to prevent them.

To understand what causes cavities, it’s important to first look at how teeth are formed and maintained. Teeth are made up of two main layers – an outer enamel layer and an inner dentin layer. The enamel is the hardest substance in the human body and acts as a protective barrier for your teeth against bacteria and acid. The dentin layer lies beneath the enamel and is softer than enamel but still strong enough to protect your teeth from damage and decay.

The primary cause of cavities is bacteria that live in your mouth called Streptococcus mutans (S. mutans). These bacteria feed on sugars from food particles left behind after you eat or drink something sugary or starchy. As they feed, they produce acids which break down tooth enamel over time leading to holes in your teeth known as cavities.

In addition to S. mutans, other factors can contribute to the development of cavities including poor oral hygiene habits such as not brushing or flossing regularly; dry mouth caused by certain medications; frequent snacking on sugary foods; drinking acidic drinks like soda; smoking or chewing tobacco; weakened immune systems due to illness or other health conditions; worn fillings or crowns that allow bacteria easy access into your tooth’s inner layers; some medical treatments such as radiation therapy for cancer patients; genetics can also play a role in cavity formation since some people have weaker tooth enamel than others making them more susceptible to decay even with good oral hygiene habits in place.

Fortunately there are steps you can take to help prevent cavity formation including brushing twice a day with fluoride-containing toothpaste, flossing daily, rinsing with an antibacterial mouthwash after meals if possible, limiting sugary snacks between meals (or replacing them with healthier options like fruits), drinking plenty of water throughout the day (this helps wash away food particles), seeing your dentist regularly for checkups/cleanings every six months (or more often if recommended), avoiding acidic drinks like soda when possible, quitting smoking/chewing tobacco if applicable, wearing a night guard if you grind/clench your teeth while sleeping at night etc..
By following these tips you can help keep both S Mutans levels low which will reduce your risk of developing cavities significantly!
