How Do Cavities Form?

Many people think that cavities are caused by excessive consumption of sugary foods, but this isn’t the only way to develop cavities. When we eat, the bacteria in our mouths break down the food particles and produce a biofilm that contains acids, sugars, and bacteria. This biofilm can accumulate on the teeth and hold harmful substances against them, gradually eroding the enamel.

Why Do Some People Get More Cavities Than Others?

Oral Hygiene Habits

Not brushing and flossing regularly can lead to the buildup of plaque, which contains harmful bacteria that can erode tooth enamel and cause cavities.

People who do not brush and floss at least twice a day are more likely to develop cavities than those who maintain good oral hygiene habits.


Eating a lot of sugary or acidic foods and drinks can create an acidic environment in the mouth, which can lead to tooth decay. Additionally, snacking throughout the day can increase the risk of cavities, as it does not give the mouth enough time to neutralize acid and repair tooth enamel.

If you consume a lot of sugary or acidic foods and drinks, especially between meals, you are more prone to cavities than those who maintain a healthy diet.


Certain genetic variations can affect the strength of tooth enamel, making it more susceptible to cavities. Some people may be genetically predisposed to tooth decay, regardless of their oral hygiene habits or diet.  

If your family has a history of cavities, you may be more likely to develop them as well and it’s important you let your dentist in Plantation, Fl know about this.  

Dry Mouth

Saliva helps to neutralize acid in the mouth and wash away harmful bacteria. People who have a dry mouth due to medication, medical conditions, or aging may be more prone to cavities.  

Without enough saliva to neutralize acid and wash away bacteria, the risk of tooth decay increases. If you have a dry mouth, it is important to talk to your dentist about ways to manage the condition and reduce your risk of cavities.

Tooth Structure

The structure of your teeth can also affect your likelihood of developing cavities. Teeth with deep pits and fissures can trap food and bacteria, making them more difficult to clean and increasing the risk of cavities.  

Crowded teeth can also be more challenging to keep clean, allowing bacteria to accumulate and cause decay. In these cases, your dentist may recommend dental sealants or orthodontic treatment to help prevent cavities.

Information to Consider

Did you know that cavities can be contagious? The bacteria responsible for cavities can be transmitted from person to person through saliva, making it important to avoid sharing utensils or toothbrushes with others. This could be another factor that’s causing your cavities!
