What Does a Cavity Look Like?

by

Cavities, also known as dental caries, are one of the most widespread oral health problems worldwide. They form when the hard surface of a tooth (enamel) is damaged by acids produced by bacteria in plaque. Cavities can develop in anyone, regardless of age, and recognising their appearance at various stages can help prevent serious dental issues.

This guide delves into the physical signs, stages, causes, and treatment of cavities to help you maintain optimal oral health. Understanding cavities early can save you from discomfort and costly treatments.

How Can You Spot a Cavity?

Recognising the Early Signs of Cavities

At the earliest stage, cavities can appear as chalky white spots on your teeth. These spots indicate a process called demineralisation, where the enamel begins to lose essential minerals. At this point, cavities are not easily noticeable without professional dental examination.

As the condition worsens, the tooth may show:

  • Brown or black spots.
  • Visible holes or pits.
  • Discolouration that looks darkened in areas near the chewing surface or between teeth.

Where Do Cavities Commonly Appear?

Cavities can develop anywhere on the tooth’s surface but are most often found in:

  • Chewing Surfaces: Grooves and pits on molars trap food particles and bacteria.
  • Between Teeth: Hard-to-reach areas are more prone to decay.
  • Near the Gum Line: Plaque build-up close to the gums can lead to decay.
  • Around Existing Fillings or Crowns: Older dental work can wear down, creating gaps for bacteria.

What Are the Stages of a Cavity?

Cavities develop over time, progressing through distinct stages. Recognising these stages can guide treatment decisions and prevent further complications.

Stages of Cavity Development

Stage Appearance Symptoms Treatment
Early (White Spot) Chalky white spots on enamel None or mild sensitivity Fluoride treatments
Enamel Decay Brown or black discolouration Sensitivity to hot/cold/sweet Dental filling
Dentin Decay Larger, visible holes or pits Pain when biting, bad breath Filling or crown
Pulp Infection Severe tooth discolouration, swelling Persistent, throbbing pain Root canal therapy
Abscess Swelling, pus, and severe pain Fever, swollen lymph nodes Root canal or extraction

Each stage highlights the importance of timely detection and treatment. For instance, fluoride treatments can reverse the early stages of demineralisation, while advanced stages may require invasive procedures such as root canals.

What Are the Symptoms of a Cavity?

Many people fail to realise they have a cavity until they experience discomfort. Below are some symptoms that may indicate the presence of a cavity:

Physical Signs

  • Tooth Discolouration: Ranging from white spots to brown or black stains.
  • Visible Holes or Pits: Damage on the surface of the tooth.
  • Chipped or Broken Teeth: A sign of severe decay weakening the tooth.

Sensory Symptoms

  • Sensitivity: Pain or discomfort when eating hot, cold, or sugary foods.
  • Toothache: A persistent, throbbing pain that may worsen at night or during chewing.
  • Bad Breath: Caused by trapped bacteria in the decayed area.

Progressive Symptoms

  • Swelling: Around the affected tooth, particularly in severe cases.
  • Pus Formation: A clear sign of an abscess, which needs immediate treatment.

What Causes Cavities to Form?

Cavities result from a complex interaction between diet, oral hygiene, and bacteria. Here’s how cavities develop:

  1. Plaque Buildup:
    • Plaque forms on the teeth after consuming sugary or starchy foods.
    • Bacteria in the plaque produce acids that weaken tooth enamel.
  2. Enamel Demineralisation:
    • The acids strip away essential minerals from the enamel, making it porous and prone to damage.
  3. Progression to Dentin and Pulp:
    • If untreated, the damage spreads deeper, affecting the softer dentin and eventually reaching the pulp, which houses nerves and blood vessels.
  4. Advanced Decay:
    • The infection may spread to surrounding tissues, leading to abscesses or systemic issues.

How Are Cavities Diagnosed and Treated?

Diagnostic Techniques

  • Visual Inspection: Dentists can often spot cavities during a routine check-up.
  • Probing: Special dental tools are used to detect soft spots on the tooth.
  • X-rays: Essential for identifying cavities between teeth or beneath fillings.

Treatment Options

The treatment approach depends on the severity of the cavity:

  • Fluoride Treatments: Effective in reversing early-stage cavities.
  • Dental Fillings: Used to restore teeth with moderate decay.
  • Crowns: Recommended for extensive damage where the tooth structure is compromised.
  • Root Canals: Necessary when decay reaches the pulp, causing infection.
  • Extractions: For severely damaged teeth that cannot be saved.

How Can You Prevent Cavities?

Prevention is key to maintaining long-term oral health. Here are essential steps to minimise the risk of cavities:

  • Brush and Floss Regularly: Use fluoride toothpaste and clean between teeth daily.
  • Limit Sugary Foods: Reduce consumption of sweetened beverages and snacks.
  • Drink Water: Fluoridated water strengthens enamel and washes away food particles.
  • Visit Your Dentist: Regular dental check-ups can catch cavities early.
  • Use Sealants: Protective coatings on molars reduce the risk of decay.

FAQs

1. What does an early cavity look like?

An early cavity appears as white or chalky spots on the enamel caused by demineralisation. At this stage, no pain or discomfort is usually present.

2. Can cavities be reversed?

Early-stage cavities (white spots) can be reversed with fluoride treatments and improved oral hygiene, but once decay progresses, professional treatment is needed.

3. How do I know if I have a hidden cavity?

Hidden cavities, such as those between teeth, may not show visible signs but can cause sensitivity or discomfort. A dentist can confirm them using X-rays.

4. Are children more at risk of cavities?

Yes, due to thinner enamel and higher sugar intake, children are more susceptible. Preventative measures like fissure sealants are highly effective.

5. Do cavities always hurt?

Not always. Cavities may not cause pain until they reach the dentin or pulp. Regular check-ups are essential for early detection.

6. Can fillings fix deep cavities?

Yes, fillings can repair moderately deep cavities. However, if the cavity reaches the pulp, a root canal or crown may be required.
