This comprehensive guide will unravel the mystery and answer the question, “What does a cavity look like?”

Knowing how to spot cavities early improves the odds of saving the tooth and prevents decay from affecting adjacent teeth.

To help you maintain optimal oral health, let’s explore dental decay, its causes, and prevention. You’ll gain valuable insights into maintaining good oral hygiene and detecting those cavities early on.

What does a cavity look like?

A cavity, also known as dental caries, is a common oral health issue that affects people of all ages.

But what does a cavity look like?

The appearance of a cavity can look different based on its severity and location.

In its initial stages, a cavity may appear as a small white spot on the tooth enamel, often unnoticed by the naked eye.

As the decay progresses, the cavity may turn yellow, brown, or black and become more visible.

Early signs of cavities

Early detection of cavities is vital for preventing further damage to your teeth.

Look out for the following signs that may indicate the presence of a cavity:

Tooth sensitivity: Increased sensitivity to hot or cold foods and beverages can be an early warning sign of tooth decay. If you experience discomfort or pain when consuming something hot or cold, it’s time to pay attention.

Visible holes or pits: As a cavity progresses, it may develop into a visible hole or pit on the surface of the affected tooth. These indentations can vary in size and are usually accompanied by discoloration.

Toothache: A persistent toothache, especially when biting down or applying pressure, may indicate an advanced cavity.

The pain can be sharp or dull and might come and go.

Bad breath: Cavities can create an environment where bacteria thrive.

The byproducts of bacterial growth can cause persistent bad breath that doesn’t go away even after brushing or using mouthwash.

Visible stains: Stains on the surface of your teeth, ranging from white to dark brown or black, can indicate tooth decay.

These stains are often localized and appear as patches.

Moderate to advanced stages of cavities

If left untreated, cavities can become more severe, leading to more noticeable signs and symptoms.

At this point, it becomes even more crucial to seek dental care.

Here are some characteristics of cavities in moderate to advanced stages:

Visible holes or craters: As the decay spreads deeper into the tooth, larger holes or craters may become visible on the affected tooth’s surface.

These cavities may have jagged edges and can be quite prominent.

Tooth fracture: In some cases, the weakened tooth structure due to decay can lead to fractures or chips.

This can cause sharp pain and sensitivity.

Pus or abscess: A dental abscess or pus-filled sac may form around the tooth root if a cavity progresses to an advanced stage.

This can cause severe pain, swelling, and even fever.

Loose teeth: Cavities that reach the inner layers of the tooth can weaken the structure and result in loose teeth.

If you notice a loose tooth, seeking immediate dental attention is crucial.

Radiating pain: In advanced stages, cavities can cause radiating pain that extends beyond the affected tooth.

This pain can spread to the jaw, face, and even the ear. It may be a constant ache or a sharp, shooting pain.

Gum inflammation: As the decay progresses and reaches the tooth’s root, it can lead to gum inflammation and tenderness.

You may notice redness, swelling, and sensitivity in the surrounding gum tissues.

It’s important to note that the appearance and symptoms of cavities can vary from person to person.

Regular dental checkups and professional examinations are crucial for accurate diagnosis and timely treatment.


In conclusion, understanding what cavities look like is important for maintaining good dental health.

The appearance of a cavity can range from small white spots to visible holes or stains on the teeth.

Early detection and treatment are key to preventing further damage and complications.
