When visiting the dentist, you might be surprised to learn that you have a cavity. Dental cavities are permanently damaged areas in a tooth's hard surface that create tiny holes. Cavities are a sign of tooth decay, and the problem is prevalent among children and adults. Your dentist can fill cavities to prevent further issues, but you can reduce your risk of developing tooth decay by learning about the most common causes of dental cavities. 

How Do Cavities Develop?

1. Poor Oral Hygiene

Tooth decay from oral bacteria is responsible for cavities forming in teeth. Oral bacteria are essential for helping break down food and beverages, but too many bacteria can eat away at tooth enamel. 

Brushing and flossing your teeth at least twice a day is the best way to prevent plaque, the sticky, bacteria-filled film that sticks to your teeth. Without proper oral hygiene habits, plaque will form and increase your risk of developing cavities. 

2. Excessive Sugar and Carbohydrate Consumption

Children often develop cavities because of the sweets and carbs they eat. Some adults also have a lot of sugary and starchy foods in their diet. Unfortunately, oral bacteria feed off them and produce damaging acidic waste that eats away at tooth enamel. 

Foods like candy, soda, bread, milk, fruit, and juice contribute to cavities. However, you can reduce the risk of high acid levels in your mouth by brushing your teeth soon after consuming sugars or carbohydrates or rinsing your mouth with water. 

3. Teeth Grinding

Teeth grinding is a lesser-known cause of cavities, but it's relatively common. If you feel tense, you might clench your teeth, but most people unknowingly grind their teeth while sleeping. This action is problematic because it causes premature wear on the hard outer layer of teeth, leaving them vulnerable to cavities. The thinner your enamel becomes, the more likely it is for bacteria to enter a tooth and cause permanent damage.
