Cavities may begin small, but they can contribute to discomfort, changes in your bite, and more significant dental concerns if left untreated. These tiny holes develop when plaque bacteria mix with sugars in your food, producing acids that gradually wear away the enamel, the tooth’s outer protective layer.
While a filling may be required to repair the damage, maintaining a strong preventive routine can help reduce the risk of cavities forming. Brushing, flossing, and attending regular checkups all support long-term oral health and help protect your confident smile.
What Causes Tooth Decay?
Tooth decay occurs when acids produced by bacteria gradually break down enamel. This erosion can eventually lead to cavities, which damage the structure of the tooth. Although they’re common in children, cavities can affect people of all ages.
Plaque is a sticky film that builds up on teeth and plays a key role in tooth decay. When sugary or starchy foods are consumed, plaque bacteria feed on them and release acids that attack enamel.
Without treatment, decay may reach deeper layers of the tooth, including the dentin and, eventually, the pulp, where nerves and blood vessels are located. Early detection and regular dental visits are essential to help prevent discomfort and more serious issues.
The 5 Stages of Cavity Formation
Cavities don’t appear all at once; they progress through stages, with several chances for early intervention.
Stage 1: Initial Demineralization
Acids start pulling essential minerals from the enamel, creating weak spots that may appear as white patches. These early changes can often be reversed with the use of fluoride toothpaste and fluoridated water, which help support enamel strength.
Stage 2: Enamel Breakdown
As demineralization continues, the enamel erodes further. Small holes can form, marking the early stage of a cavity. A dental filling can typically restore the tooth and help stop decay from progressing.
Stage 3: Dentin Involvement
When decay reaches the dentin, it can spread more easily. Dentin is softer and more porous than enamel, and damage to this layer often leads to sensitivity, especially to sweet, hot, and cold foods. Treatment is often needed to prevent further damage.
Stage 4: Pulp Damage
If decay extends into the pulp, pain may occur. The pulp contains nerves and blood vessels, and infection in this area can cause throbbing discomfort or sensitivity while chewing. In some cases, a root canal may be required to preserve the tooth.
Stage 5: Abscess Development
At this point, the infection has moved beyond the tooth and into the surrounding tissue, typically resulting in a painful abscess. Signs can include swelling, fever, or enlarged lymph nodes. Emergency care may be needed, with treatment options including draining the abscess, a root canal, or tooth removal.
Cavity Signs to Watch For
Cavities can develop quietly, but noticing signs early on can lead to simpler treatment. Common indicators include:
- Tooth sensitivity to hot, cold, or sweet foods
- White or dark spots on the surface of the tooth
- Visible pits or holes in the teeth
- Pain when chewing or biting
- Ongoing or throbbing toothaches
If any of these symptoms occur, scheduling a dental exam is a helpful next step.
What Increases the Risk of Cavities?
Understanding the factors that contribute to tooth decay can help reduce the risk for you and your family.
Poor Brushing & Flossing
Infrequent brushing allows plaque to build up and feed cavity-causing bacteria. Flossing helps remove plaque and bacteria between your teeth and under the gumline—areas your toothbrush can’t always clean.
What Helps: Brush your teeth every morning and again at night using fluoride toothpaste. Floss once a day to help remove food and plaque between your teeth and around your gums.
Sugary Foods & Drinks
When you eat sugary foods, the bacteria in your mouth eat them too. As they break it down, they create acid, and that acid can slowly wear away your enamel and lead to cavities.
What Helps: Choose snacks like cheese, vegetables, or nuts while limiting sugary treats to occasional consumption.
Acidic Diet Choices
Eating citrus fruits, soda, and energy drinks can slowly erode enamel.
What Helps: Pair acidic foods with meals, and rinse with water after drinking pop or juice.
Gum Recession
Receding gums caused by brushing too hard or gum disease expose the roots that lack enamel protection.
What Helps: Use a soft-bristled toothbrush and visit your dentist regularly for cleanings that support gum health.
Lack of Fluoride
Fluoride helps strengthen enamel and support early-stage repair.
What Helps: Brush with fluoride toothpaste and find out whether your community’s water supply contains fluoride.
