Dental cavities, also known as caries or tooth decay, are among the most common health problems worldwide, affecting people of all ages. According to data from the Centers for Disease Control and Prevention (CDC), about one in four adults aged 20 to 64 in the United States has at least one cavity.

While often considered a minor nuisance, untreated cavities can lead to discomfort, infection, and tooth loss. They can progress to infections, lead to the formation of abscesses beneath the gums, and, though rare, can result in life-threatening complications, especially when infections spread to other parts of the body.

Fortunately, you can defeat cavities with dental fillings. This basic restorative procedure saves your smile and protects your dental health. Learn how dental fillings for cavities can be your best defense against tooth decay, helping you maintain a pain-free smile.

Common Causes of Dental Cavities

Cavities occur when the hard enamel layer of your teeth is damaged by acid produced by bacteria in your mouth. These bacteria thrive on food particles left on your teeth, particularly sugars and starches. Over time, the acid erodes the enamel, leading to cavities. Several factors increase the risk of developing cavities, including:

Poor Oral Hygiene

Poor oral hygiene contributes to the development of cavities and overall dental health deterioration. When you do not regularly brush and floss, plaque – a sticky film of bacteria – accumulates on the teeth and gum line. This plaque is problematic for several reasons:

Acid production. The bacteria in plaque feed on the sugars and starches left behind in your mouth after eating. As they digest these food particles, they produce acids that can erode the tooth enamel. This acid demineralizes and breaks down the enamel, forming pits and holes where bacteria can invade the inner dentin layer of your teeth.
Tartar formation. If plaque is not removed regularly through brushing and flossing, it can harden into tartar, which creates a rough surface that harbors more bacteria. It can form above and below the gum line, leading to serious dental issues like gum disease.
Gum disease. The gradual buildup of plaque and tartar can irritate the gum tissue, leading to gingivitis or early gum disease. If not treated promptly, gingivitis can become periodontitis, a more serious type of gum disease that can damage the soft tissue and bone supporting the teeth, potentially causing the tooth to fall out.
Bad breath. Poor oral hygiene and the resulting plaque build-up can also cause halitosis or chronic bad breath, which can be socially embarrassing and affect your confidence and quality of life.
Overall health impact. Research has shown that poor oral hygiene and the resulting dental issues can have a broader impact on overall health. Conditions like periodontal disease have been linked to heart disease, diabetes, and other systemic health problems.

Sugary and Acidic Foods and Drinks

Frequently eating acidic and sugary foods and drinks can lead to the development of dental cavities. Some of the ways in which these dietary choices can lead to cavities include:

Sugar and bacteria interaction. Our mouths are home to various bacteria, some of which are harmful and feed on the sugars found in the foods and drinks we consume. When these bacteria digest sugar, they produce acids as a byproduct. This acid is the primary cause of tooth enamel erosion, leading to cavities.
Acidic food and enamel erosion. Acidic foods and beverages, such as citrus fruits, soda, and certain sports drinks, can weaken and erode tooth enamel. Over time, this erosion makes the teeth more susceptible to decay. Acidic conditions in the mouth can also speed up the damage caused by sugar-fed bacteria.
Frequency of exposure. It’s not just the amount of sugar and acid consumed but also the frequency of exposure that affects cavity risk. Snacking on sugary or acidic foods throughout the day continuously exposes the teeth to harmful conditions, giving them less time to recover and remineralize.
Sticky and slow-dissolving foods. Certain sugary foods, like candies, cookies, and dried fruits, can stick to the teeth longer, prolonging the exposure to sugars. Similarly, sipping sugary drinks over an extended period continuously bathes the teeth in sugar and acid.
Neutralizing saliva. Saliva neutralizes acids in the mouth and remineralizes tooth enamel. However, frequent consumption of sugary and acidic foods can overwhelm saliva’s ability to maintain a balanced oral pH and protect the teeth.
Hidden sugars. It’s also important to be aware of hidden sugars in processed foods, including items not typically considered sweet, like certain breads, condiments, and cereals. These hidden sugars can contribute to the overall sugar intake, increasing the risk of tooth decay.

Lack of Fluoride

The absence of fluoride in your oral hygiene routine and water supply can increase the risk of developing dental cavities. Fluoride is a naturally occurring mineral that contributes to the crystalline structure of your tooth enamel. Acid and sugar leech fluoride from your teeth, leaving the outer layer weak and vulnerable to decay. Here is a more in-depth look at how fluoride benefits your teeth:

Enamel strengthening. Fluoride is known for its ability to strengthen tooth enamel, the hard, protective outer layer of teeth. It aids in remineralization, where lost mineral content due to acid is restored. This process repairs weakened enamel and makes it more resistant to future decay.
Reversing early decay. In the early stages of tooth decay, fluoride can help reverse the damage. It encourages the development of new enamel crystals that are larger and more acid-resistant than the original enamel, effectively combating the early signs of cavities.
Inhibiting harmful bacteria. Fluoride can also inhibit the growth of harmful oral bacteria. It interferes with the acid production of these bacteria, reducing the amount of acid that attacks the teeth.
Source in toothpaste and water. Fluoride is commonly added to toothpaste, and regularly using it when brushing is one of the easiest ways to ensure adequate fluoride exposure for teeth. In many communities, fluoride is also added to the public water supply – a process known as water fluoridation. This has been shown to reduce the incidence of cavities in the population.
Fluoride treatments: For individuals at high risk of dental cavities, such as those with Sjögren’s syndrome, dentists may recommend additional fluoride treatments. These can include professional fluoride applications in the dental office, prescription fluoride gels, or mouth rinses.
Balancing fluoride intake. While fluoride is beneficial, monitoring and balancing its intake is important, especially in children. Excessive fluoride during tooth development can lead to dental fluorosis, a condition that causes changes in the appearance of tooth enamel.
Fluoride for all ages. People of all ages benefit from fluoride. Children need it to protect their developing teeth, and adults need it to maintain their tooth enamel’s integrity and combat the continual exposure to acids from food and bacteria.

Dry Mouth

Dry mouth, medically known as xerostomia, increases the risk of developing dental cavities. Saliva contains minerals, including fluoride and calcium, that are critical for enamel formation. It also removes harmful bacteria and food particles from your mouth. The following are some ways saliva benefits oral health and reduces the risk of cavities:

Reduced natural cleansing. Saliva continuously washes away food particles and debris from the teeth and gums. Without adequate saliva, these particles remain in the mouth longer, providing a breeding ground for cavity-causing bacteria.
Decreased acid neutralization. One of saliva’s key functions is to neutralize the acids produced by bacteria in the mouth. These acids are responsible for eroding tooth enamel and leading to cavities. Without sufficient saliva, the mouth’s pH balance is disrupted, creating an acidic environment conducive to tooth decay.
Lack of remineralization. Saliva is rich in minerals like calcium and phosphate that help repair and strengthen tooth enamel through a process called remineralization. A dry mouth lacks these essential minerals, preventing the natural repair process of the enamel and making teeth more susceptible to decay.
Compromised oral microbiome. Saliva helps maintain a balanced oral microbiome by controlling the growth of harmful bacteria. A reduction in saliva can disrupt this balance, allowing cavity-causing bacteria to thrive.
Increased plaque formation. Saliva acts as a natural barrier against plaque buildup. With reduced saliva flow, plaque adheres more readily to teeth and gum surfaces, increasing the risk of cavities and gum disease.
Difficulty eating and speaking. A dry mouth can make it challenging to chew and swallow food, which may lead to changes in eating habits and reduced oral hygiene. Additionally, the discomfort associated with dry mouth might affect speaking and lead to less frequent brushing and flossing.
Long-term oral health issues. Persistent dry mouth can lead to chronic oral health problems, including a higher risk of cavities, gum disease, and oral fungal infections.

The Role of Dental Fillings in Fighting Cavities

When a cavity develops, address it promptly. Dental fillings are the most common treatment for cavities and play a vital role in restorative dentistry.

Procedure for dental fillings for cavities:

Diagnosis. The first step is identifying the cavity, typically during a routine dental checkup. Your dentist will use various tools and X-rays to detect cavities. Owens Cosmetic and Family Dentistry uses state-of-the-art digital dental X-rays and intraoral cameras to take precise images of your teeth and gums.
Preparation. The area around the cavity is numbed using a local anesthetic. Then, your dentist removes the decayed part of the tooth using a drill.
Filling. Once the decay is removed, your dentist cleans and sterilizes the cavity to eliminate bacteria and debris. The cleaned cavity is then filled with a tooth-colored composite resin filling material.
Polishing. After the filling is in place, your dentist will shape and polish it to match your tooth’s natural contours and check your bite.

Common Materials Used for Dental Fillings

If you have tooth decay or cavities and need a filling, there are several different materials your dentist might use. Amalgam and gold fillings were used in the past due to their durability; however, because they are highly noticeable, most people opt for metal-free dental fillings.

Owens Cosmetic and Family Dentistry offers high-quality tooth-colored composite resin dental fillings. These fillings blend seamlessly with your natural teeth while providing a strong, durable chewing surface that can last up to 10 years with the proper care.

Benefits of Getting Dental Fillings

Dental fillings offer multiple benefits, protecting oral health and improving overall functionality and aesthetics. Here’s a closer look at these advantages:

Prevent further decay. Fillings stop cavities from growing larger and reaching the deeper layers of the tooth, which can cause pain and lead to more serious issues like pulp infections, which may require a root canal treatment.
Restore tooth function. Cavities may impair your ability to chew and speak. Fillings fully restore function to the teeth, allowing you to chew comfortably and speak clearly.
Aesthetic improvement. Tooth-colored fillings offer an aesthetic advantage by restoring the natural appearance of decayed or damaged teeth. Unlike metal fillings, these composite materials blend with your natural teeth, making fillings virtually invisible and ensuring your smile remains bright and even.
Longevity. With proper care, most composite dental fillings last 10 years. This makes them a cost-effective solution for treating cavities, offering long-term protection for your teeth.

Caring for Your Dental Fillings

Maintaining your dental fillings is essential for their longevity and effectiveness. Some care tips to ensure your fillings stay in the best condition include:

Oral hygiene. Maintaining good oral hygiene will help preserve your fillings. Brush your teeth twice daily using fluoride toothpaste, which helps strengthen tooth enamel and prevent decay.
Flossing daily is also important to remove food particles and plaque from between your teeth and around the gumline, areas your toothbrush can’t reach. This prevents the buildup of plaque, which can lead to new cavities around your fillings.
Regular dental visits. Schedule dental checkups and cleanings at least twice a year. These visits allow your dentist to monitor the condition of your fillings and your overall oral health. Regular professional cleanings help remove tartar that can’t be brushed or flossed away, keeping your teeth and fillings in optimal condition.
Avoid hard foods. Avoid hard foods like ice, candies, or popcorn kernels. Chewing on these can crack or damage your fillings.
Limit sugary foods and drinks. Reducing your intake of sugary foods and beverages benefits your overall dental health. Sugar can contribute to tooth decay, leading to cavities around and under your fillings. Reducing sugar helps prevent new cavities from forming and extends the lifespan of your fillings.

Importance of Regular Dental Check-ups

It’s important to have regular dental check-ups to catch cavities early. By visiting your dentist frequently, they can identify early signs of tooth decay before it turns into a bigger issue. Catching cavities early means your dentist can treat them with smaller fillings and helps save more of your natural tooth.

Considering that 52% of kids have had cavities in baby teeth, 57% of teens have cavities in their permanent teeth, and a whopping 90% of adults have had at least one cavity, it’s clear why regular dentist visits are important at all ages.

While dental fillings are durable, they aren’t permanent and can deteriorate or loosen over time. Your dentist will inspect your fillings during your regular dental check-ups, which typically occur every six months.

This routine examination allows for any necessary maintenance, such as repairing or replacing fillings, ensuring they continue to provide the best protection for your teeth and maintain your overall dental health. Regular dental visits are key to prolonging the life of your fillings and keeping your teeth in good condition.
