You have heard the basics — brush twice a day, floss daily. But cavity prevention is a multi-faceted area and there are evidence-based strategies beyond the standard advice that make a real difference.
Diet: It Is Not Just About Sugar
Sugar feeds the bacteria that produce the acids that cause cavities — but frequency matters more than total amount. Sipping a sugary drink over hours is more damaging than drinking it quickly. Frequent snacking keeps pH levels low in the mouth for extended periods. Minimizing snacking frequency and rinsing with water after eating or drinking is more effective than most people realize.
Fluoride: The Most Evidence-Based Cavity Prevention Tool
Fluoride is incorporated into enamel and makes it more resistant to acid attack. Fluoride toothpaste (1000+ ppm for adults) is essential. Fluoride varnish applied by a dental professional provides a concentrated, time-released fluoride treatment that significantly reduces cavity risk — particularly for high-risk patients.
Dental Sealants
The grooves on the chewing surfaces of back teeth are impossible to clean fully — they are thinner than a toothbrush bristle. Sealants are a thin plastic coating applied to these grooves that effectively seals out bacteria and food. They are highly effective for children, but adults with deep grooves can benefit too.
Saliva: Your Natural Defence
Saliva neutralizes acids, washes away food, and delivers minerals that remineralize enamel. Dry mouth (caused by medications, mouth breathing, or dehydration) significantly increases cavity risk. Stay hydrated, breathe through your nose, and speak with your dentist if dry mouth is an issue. At Smileworks Dental in Calgary, we assess your individual cavity risk at each check-up and tailor your prevention plan accordingly.
