Patients always want to know “Doc, do I have a cavity? What is a cavity?” Let’s break it down!
The word “cavity” is short for “cavitation.” A cavitation is a hole or hollowness in the tooth that is broken down tooth structure. Imagine tooth structure that was once strong, hard, and healthy becomes soft, mushy and decayed.
How do cavities form?
When we eat carbohydrates the bacteria in our mouth metabolize sugars and secrete acid as a byproduct. Long term exposure of this acid metabolite, breaks down enamel which leads to a cavity.
How do cavities appear?
Sometimes cavities can be visually seen with the naked eye, other times we need x-rays to diagnose them. They can appear chalky white, brown, black or gray.
Do cavities hurt?
Some cavities cause pain and sometimes cavities are completely asymptomatic, meaning you cannot feel anything. The best way to diagnose a cavity is to have a visual and x-ray examination with a dental professional. Unfortunately, once cavities penetrate the enamel into the second layer of tooth called dentin, they will not heal on their own and need to be treated by a dental professional.
How do I prevent getting cavities?
The best ways to prevent cavities are the following:
- Excellent homecare including brushing twice daily and flossing once daily before bed
- Regular hygiene visits with a dental professional, including examinations with x-rays
- Using a toothpaste with hydroxyapatite
Cavities are a prevalent dental disease, but with proper care and attention they can be effectively avoided. By maintaining good oral hygiene, making smart dietary choices, and visiting your dentist regularly, you can keep your smile healthy and cavity-free. Remember, early intervention is key—if you suspect you have a cavity, don’t hesitate to consult with your dentist. Your teeth will thank you!
