We’ve all heard about cavities since childhood. But how fast can one actually form? Is it something that takes months—or could tooth decay start in just days? According to Dr. Kevin Molldrem, a leading general dentist in Lakeville, the truth might surprise you. In 2025, with modern diets and lifestyle habits, cavities can begin developing much faster than most people think.

Understanding the Cavity Timeline
Contrary to popular belief, a cavity doesn’t just appear overnight, but it also doesn’t take years. A cavity forms when harmful bacteria in the mouth feed on sugars and produce acids that wear down tooth enamel. If left unchecked, this process can begin in as little as 24 to 72 hours—yes, that fast—especially in individuals with poor oral hygiene or diets high in sugar and acids.
Kevin Molldrem DDS explains that cavities progress in stages. It starts with demineralization, where enamel begins to weaken. If no action is taken, the enamel eventually breaks down, creating a visible cavity. By the time you feel pain, the decay has likely reached the inner layers of your tooth.
Factors That Speed Up Cavity Formation
Dr. Kevin Molldrem emphasizes that while not everyone’s risk is the same, several factors can accelerate how quickly a cavity forms:
Frequent Snacking: Constantly exposing your teeth to sugar, even from healthy snacks like fruit or granola bars, increases acid attacks.
Poor Brushing Habits: Missing even a few brushing sessions can allow plaque to harden and bacteria to grow rapidly.
Dry Mouth: Saliva helps neutralize acids; a dry mouth means less natural protection.
Genetics and Enamel Strength: Some individuals naturally have softer enamel, making them more vulnerable.
Kevin Molldrem reminds patients that these factors make prevention and regular care more important than ever.
The Importance of Early Detection in 2025
Thanks to advancements in dental technology, Kevin Molldrem DDS can now detect cavities in their earliest stages—long before you feel any symptoms. Digital X-rays and cavity-detecting lasers allow for fast, painless diagnostics during your routine exams.
Dr. Kevin Molldrem encourages patients to visit at least twice a year, as these early appointments can mean the difference between a small, reversible issue and a large, painful one requiring fillings or even root canals.
Prevention: Still the Best Treatment
The good news is that cavities are preventable. Kevin Molldrem recommends the following simple yet powerful steps:
Brush twice a day with fluoride toothpaste
Floss daily to remove food and plaque between teeth
Limit sugary and acidic foods and drinks
Use a fluoride mouthwash for added protection
Get regular dental check-ups and cleanings
By following this guidance, you can dramatically reduce your risk—regardless of how fast a cavity might try to form.
