Want to know what does a cavity look like? You are in the right place!

According to a recent report by CDC Oral Health, 1 in 4 adults suffer from untreated cavities. Even, it's estimated that 90% of adults have experienced at least one cavity in their lifetime. This concerning figure reflects a dual challenge: a lack of awareness about dental issues and a common fear of dental visits due to high costs. As a result, cavities often go unnoticed until they escalate into severe problems requiring immediate attention.

Understanding “What do cavities look like?” is crucial for early detection and timely intervention. By recognizing the signs, you can determine whether you need treatment.  

So, What Does a Cavity Look Like?

Cavities form when leftover food remnants combine with bacteria in your mouth, becoming a sticky layer called plaque. If this plaque accumulates around your gumline, it triggers gingivitis, which is gum inflammation. It contributes to tooth decay and cavities, which further develop into a small hole in the gums. 

A cavity can appear in various forms depending on its stage and location on the tooth. To know how do cavities look like, read further: 

1️⃣ Small white spots on the tooth enamel are visible in the early stages of cavity development.

2️⃣ When there is significant decay, the white spot turns into a brown or black spot.

3️⃣ In cases of deeper damage, it could turn into a rough or pitted area on the tooth surface. 

4️⃣ If it turns into a severe infection, large holes or pits appear in the tooth. Moreover, it may turn red or swollen due to infection or inflammation. 

Can You See Cavities?

Absolutely!

Look out for these indicators to find out if you have a cavity.

➡️ Color

   ♦ White Spots: Early stages of tooth decay may present as white spots on the enamel.

       It majorly signals demineralization before a cavity has formed.

   ♦ Brown or Black Spot: The most common visual sign of a cavity is a brown, black, or

       darkened spot on the tooth's surface. 

➡️ Surface Texture

The affected area may feel rough or have a noticeable indentation. This is due to the enamel being eroded by acids produced by bacteria.

➡️ Location

Cavities often occur on the chewing surfaces of molars, where food particles can get trapped. However, you may see cavities on the side of the tooth or near the gum line.

What Does a Cavity Look Like on a Molar

A cavity on a molar often appears as a small dark spot, pit, or hole on the tooth's surface. It may look brown or black and can be found in the grooves or between the teeth. As it worsens, the cavity can become larger and more noticeable, leading to pain or sensitivity.

What Does a Cavity Feel Like

A cavity can lead to a variety of sensations and discomfort in the affected tooth. Even some people may say, “I can feel a hole in my tooth with my tongue,” which often indicates the presence of a more significant cavity. 

Therefore, if you have a cavity, you might experience the following symptoms:

► Tooth Sensitivity

You might experience sharp pain when consuming hot or cold foods and beverages or even sweets. In fact, this sensitivity indicates that the cavity is affecting the tooth’s nerves.

► Toothache

"Do cavities hurt?"

Many people wonder about this, and the answer is a resounding yes. Cavities can cause a persistent, dull ache in the tooth, but it’s not always constant. You might also experience sharp, intermittent pain. 

► Pressure Sensitivity

The pain can occur when pressure is applied to the tooth, especially, when you chew food. This pressure can irritate the damaged area, leading to increased sensitivity.

► Lingering Discomfort

The pain or sensitivity may linger for a while after eating or drinking. It mostly happens when your tooth is exposed to extreme temperatures or sugary substances. 

How Long Does It Take for a Cavity To Form

Cavities can form at different paces based on a few key factors, like how well you care for your teeth, what you eat, and whether you use fluoride. Generally, cavities, either a pop cavity (caused by consuming too much sugar) or a gumline cavity, can start to develop within 6 months to 5 years. This process begins when the enamel starts to lose minerals. When food stays on your teeth, it mixes with bacteria and produces acids that can slowly wear away the enamel. Most importantly, if you don’t stop this by practicing good oral hygiene, like brushing and flossing regularly or getting professional cleanings, the enamel will continue to break. 

How Cavities Grow Through Each Stage

1. Demineralization

This process creates white spots on the enamel, indicating the beginning of decay. Moreover, the cavity can be easily identifiable through routine checkups. The major signs are plaque or a sticky film of bacteria forming on teeth. 

2. Enamel Decay

If demineralization continues, the enamel becomes more porous and weakens further. This is when a cavity begins to form. Additionally, the affected area may become discolored and might show signs of decay, such as brown or black spots.

3. Dentin Decay

Once the enamel is damaged, the decay can reach the dentin. It is the layer beneath the enamel. At this stage, patients may start to experience sensitivity to hot, cold, or sweet foods, as the protective enamel layer is no longer intact.

4. Pulp Involvement

If the cavity is not treated, it can reach the pulp. As a result, it can lead to severe pain, infection, and inflammation, known as pulpitis. Affected individuals may require more extensive dental treatments, such as root canal therapy, to save the tooth.

5. Abscess Formation

If the decay continues unchecked, bacteria can infect the pulp and lead to the formation of an abscess (a pocket of pus at the tooth's root). This condition can cause intense pain, and swelling, and can cause cavities in between teeth.

Can You Reverse Cavities?

Yes, stage 1 early cavity is possible to reverse.

As the saying goes, prevention is better than cure. Here are some effective methods to help you avoid cavities altogether. 

  • Brush your teeth twice daily using fluoride toothpaste. Don’t forget to floss every day to eliminate plaque and prevent further decay.
  • Cut down on sugar, as bacteria in your mouth feed on it to produce acids that can erode tooth enamel.
  • Prioritize a nutrient-dense diet full of vitamins and minerals to support healthy teeth and gums.
  • Stay hydrated and consider chewing sugar-free gum to enhance saliva flow. It neutralizes acids in the mouth and delivers minerals to fortify your teeth.
  • Schedule regular dental checkups to identify early signs of decay and address them promptly. 

Nevertheless, if you notice a severe cavity on X-ray, indicating that it has gone beyond the early stages, what actions should you consider?

How Do You Get Rid of Cavities?

Cavities can sneak up on you before you even feel a thing, but regular dental checkups can help you catch them early. Undoubtedly, addressing cavities before they cause more problems can make all the difference. Still, if cavities have already occurred, these treatments can help you get rid of them. 

Fluoride Treatments

These are professional dental procedures that protect your teeth from cavities and strengthen enamel. Fluoride treatment can be done through fluoride varnish, gel or foam, mouthwash, and supplements. 

Fillings

Realistically speaking, dental fillings are very effective in repairing cavities. Additionally, they are crucial in restoring tooth function and putting a halt to further damage and discomfort. There are several types of fillings available, namely, gold fillings, silver amalgam, composite, porcelain, and glass Ionomer fillings. 

Key Takeaway

What Does a Filling Look Like?

A filling typically appears as a smooth, shiny surface within the tooth, often matching the tooth's natural color if made from composite resin. It can also be metallic in color if made from amalgam, giving it a more noticeable appearance in the mouth.

Crowns

If you're dealing with moderate to severe cavities or a rotten tooth, a dental crown may be the best solution. This treatment addresses cavities that cannot be repaired with fillings alone. Typically, a dental crown is fitted following a root canal procedure to provide lasting support and strength to the tooth. 

Root Canals

When cavities progress beyond the outer enamel and dentin layers, they can reach the tooth’s pulp, causing infection or inflammation. In such cases, a root canal becomes necessary to save the tooth and prevent further complications. 

Tooth Extractions

When a tooth is extensively damaged and no treatment can restore it, extraction becomes necessary. It’s essential to prevent further damage to the surrounding teeth. This makes extraction a proactive measure for maintaining oral health. 

Here’s a table that outlines the costs and advantages of various dental treatments for cavities.

Frequently Asked Questions (FAQs)

A cavity typically appears as a small hole or dark spot on the tooth’s surface. It may also present as a white, brown, or black discoloration, depending on the severity of the decay.

It doesn’t necessarily mean it’s too late, but it does indicate that the cavity has likely progressed. When you start feeling pain, it means that the decay has moved beyond the outer layer of the tooth (the enamel) and is affecting the underlying dentin or even the tooth's nerve.

A bad teeth X-ray often shows dark spots or shadows around the teeth, indicating decay, cavities, or infections, and may reveal bone loss around the roots. Additionally, the presence of visible abscesses or impacted teeth can indicate serious dental issues.

Healing cavities in just two days at home is not realistically possible, as cavities require professional dental treatment for effective healing. However, maintaining good oral hygiene by brushing with fluoride toothpaste, flossing, and using mouthwash can help slow down decay and promote overall dental health.

Cavities themselves are not contagious, but the bacteria that cause tooth decay can spread through saliva, such as sharing utensils or kissing. Maintaining good oral hygiene and regular dental check-ups can help prevent the spread of these harmful bacteria.

Yes, cavities can cause bad breath as they create an environment for bacteria to thrive, leading to the production of unpleasant odors.

Tooth stains are surface discolorations caused by factors like food, beverages, or poor oral hygiene. In contrast, cavities are areas of decay that penetrate the tooth enamel, leading to structural damage and potential pain.

A rotten tooth is a tooth severely damaged by decay, often caused by plaque buildup and poor oral hygiene. It appears discolored, with dark spots, and may be accompanied by pain, sensitivity, or bad breath.
