Causes of Cavities, Decay & Holes in teeth

Filtered by Oral Health Goal

What Are Cavities and How Do They Form?

A dental cavity is essentially permanent damage to the outer layer of your tooth, creating tiny openings or holes.¹This damage results from the tooth decay process, which, if left unchecked, can lead to deeper, more painful issues.¹

The Step-by-Step Progression to Tooth Decay

Plaque Buildup: Everything begins with plaque, a sticky film composed of bacteria, residual food particles, and saliva. When not removed regularly, plaque creates an environment conducive to decay.²

Meet Streptococcus mutans: This particular bacterium thrives in plaque, especially when sugary or starchy foods are consumed. ³ The bacteria metabolize these sugars and produce acids as byproducts.

Acid Attack: These acids begin to erode your tooth’s enamel—the protective outer layer of your teeth.

Enamel Weakening: Over time, as the enamel loses minerals, you might notice tiny white spots on your teeth—an early warning sign of decay.

Cavity Formation: Eventually, continuous acid exposure creates small holes, or cavities, in the enamel.

Deeper Damage: If untreated, these cavities can penetrate deeper, eventually reaching the inner layers of the tooth, leading to significant pain, infection, and even tooth loss.

If left unaddressed, cavities not only cause more severe decay but can also result in persistent bad breath and painful infections.

Understanding the Root Causes of Cavities and Tooth Decay

The Impact of Sugary and Starchy Foods

Sugary treats and starchy snacks are not just temporary indulgences—they can pose a long-term risk to your dental health.⁴ When these foods are consumed:

Bacteria in your mouth feed on the sugars and starches, producing acids that corrode your enamel.

Frequent snacking on such foods keeps acid levels high, accelerating the decay process.

Acid Erosion: How Acids Attack Tooth Enamel

Our daily diets often include acidic foods and beverages—such as citrus fruits, juices, and sodas—that contribute to enamel erosion. Additionally, conditions like acid reflux or bouts of vomiting can worsen this erosion. As acids erode the enamel, your teeth become increasingly susceptible to decay.

Dry Mouth (Xerostomia) and Its Role in Decay

Saliva plays a crucial role in neutralizing oral acids and washing away harmful debris. However, when you suffer from dry mouth—whether due to medication, dehydration, or underlying medical conditions—the lack of saliva means that acids are left unchecked. This reduced saliva flow heightens the risk of cavities developing.

Poor Oral Hygiene: A Breeding Ground for Cavities

Maintaining good oral hygiene is essential to keeping cavities at bay. Here are some contributing factors when hygiene falls short:

Inadequate Brushing Techniques

Brushing at least twice a day for around two minutes each session is fundamental. However, it’s not just about the duration; it’s about technique:

Using circular motions and ensuring every tooth surface is reached.

Choosing the right toothbrush is paramount for effective cleaning.

A high-quality toothbrush, such as the DARLIE Volcanic Charcoal Toothbrush, is engineered with dual-core bristles infused with Jeju Volcanic Mineral and Japan Binchotan Charcoal that not only deliver a deep clean but also inhibit bacteria* formation, thanks to its antibacterial properties.

Neglecting to Floss Daily

Flossing is essential to remove plaque and food particles nestled between teeth—areas that toothbrushes might miss. Consistent and effective flossing helps prevent gum disease and the formation of cavities in these vulnerable spaces.

The Dangers of Tartar Buildup

Plaque left unchecked can harden into tartar (calculus), which is stubborn and difficult to remove with regular brushing. Regular dental cleanings are necessary to remove tartar and halt further decay.

Irregular Dental Check-ups

Routine visits to the dentist not only help in early detection of decay but also allow for professional cleanings and fluoride treatments, ensuring your teeth remain strong and cavity-free.

Other Factors That Increase Cavity Risk

Beyond diet and hygiene, several other elements can elevate your risk of tooth decay:

Lack of Fluoride

Fluoride plays a critical role in strengthening your tooth enamel, making it more resilient against acid attacks. It is found in fluoridated water and professional dental treatments. All DARLIE toothpastes and mouthwashes are formulated with fluoride to bolster your enamel’s defences.

Eating Disorders

Conditions such as anorexia and bulimia can lead to excessive acid exposure due to frequent vomiting, which in turn accelerates enamel erosion. Seeking professional help and adopting practices such as rinsing with water after an episode can mitigate some of the acid damage.

Medical Conditions and Medications

Certain health issues—for example, Sjögren's syndrome—or medications that reduce saliva production can create a dry mouth condition, further increasing the risk of cavities.

Age and Genetics

Both the very young and older adults are particularly vulnerable to cavities. Additionally, genetic factors can influence the natural strength of your enamel and even the composition of your saliva.
