If you have a sweet tooth—or if you’ve ever reached for a tangy candy or Vitamin C lozenge to “boost” your health—you might not realize the hidden risks to your smile. As Dr. Como of Como Dental Design, a leading Westchester dentist, often explains to patients, hard candies and ascorbic acid–based lozenges can cause significant and lasting damage to your teeth.
The combination of sugar, acid, and prolonged contact with tooth enamel creates the perfect recipe for cavities and dental erosion. For individuals with dry mouth, the problem can become even worse. Let’s explore the top five reasons why these seemingly harmless treats are a serious threat to your oral health, and what you can do to protect your smile.
Unlike soft sweets that are quickly chewed and swallowed, hard candies dissolve slowly—often over several minutes. This prolonged exposure keeps sugar in contact with your enamel for extended periods. Oral bacteria feed on that sugar and release acid as a byproduct, which weakens enamel and leads to cavities, especially to those who are cavity prone or with extensive dental work.
Even sugar-free hard candies aren’t completely risk-free; many contain acidic flavoring agents that can still wear down enamel over time.
Ascorbic acid is a form of Vitamin C frequently used in sour candies and lozenges. While Vitamin C is an essential nutrient, its acidic nature lowers the pH in your mouth, softening the enamel surface.
A 2020 study published in the Journal of Dentistry found that repeated exposure to acidic candies and lozenges significantly increased enamel wear—even in sugar-free varieties. When enamel is softened by acid, everyday chewing and brushing can wear it away, leading to permanent damage.
For many patients, especially older adults or those taking certain medications, dry mouth (xerostomia) is a daily challenge. Saliva plays a critical role in neutralizing acids, washing away food debris, and delivering minerals that repair early enamel damage.
When saliva is reduced, acids from candies or lozenges stay in contact with teeth for much longer. Some people turn to hard candies to stimulate saliva, but this can backfire—introducing more sugar and acid into an already vulnerable environment.
Cavities and erosion are related but different problems. Cavities occur when bacteria metabolize sugars and produce acids that decay enamel and dentin. Erosion, on the other hand, is direct chemical wear from acidic foods, drinks, or candies.
Hard sour candies and ascorbic acid lozenges deliver both attacks: they feed cavity-causing bacteria and directly dissolve enamel. Without intervention, this can lead to tooth decay necessitating significant dental care especially in patients with crowns or large dental restorations.
Once enamel is worn down, it cannot regenerate. Damaged areas can trap more plaque, creating a vicious cycle of decay and erosion. Patients often require restorative treatments such as tooth-colored fillings, dental bonding, or crowns to restore function and appearance.
At Como Dental Design, Dr. Como uses advanced diagnostic tools—including digital imaging and wellness scans—to detect early signs of damage and provide personalized treatment before problems become severe.
If you have dry mouth or crave something to suck on during the day, there are safer options that won’t harm your teeth:
If damage has already occurred, early intervention is key. Dr. Como recommends:
Hard candies and sour Vitamin C lozenges may seem harmless—or even health-boosting—but the combination of sugar, acid, and prolonged exposure can silently damage your teeth. For patients with dry mouth, the risks are even greater.
