What Does a Cavity Look Like?

A dental cavity is a hole in the tooth caused by acid-producing bacteria that gradually wear down the tooth. They often start as small, discoloured spots or pits on the tooth’s surface, growing into larger holes when left untreated. In many cases, they won’t be visible to the naked eye, requiring a dental X-ray for an accurate assessment.

Addressing cavities involves more than just spotting visible signs. Regular dental cleanings and exams every six months help routinely remove cavity-causing plaque and tartar buildup, protecting your teeth from more serious damage.

The Cavity Culprits

Cavities are a result of several factors coming together, including:

• Bacteria
• Acid
• Food particles
• Saliva
• Inadequate oral hygiene

Plaque builds up when bacteria in the mouth interact with food particles and saliva. If you don’t routinely remove plaque with daily brushing and flossing, it can wear away at the tooth enamel and create cavities.

How to Spot a Cavity

Cavities typically manifest as dark spots on your tooth. This discolouration can appear as brown, black, grey, and yellow. These spots are usually found in the pits or grooves of molars or in between teeth.

As cavities advance, they may lead to chips and fractures in the teeth. In extreme scenarios, deep cavities can culminate in an abscess. 

Not all cavities will be visible, but there are several symptoms that might indicate the presence of a cavity. Regardless of whether they manifest as discoloured spots on your teeth, untreated cavities can still cause significant damage to your overall oral health.

A dentist can help diagnose and treat cavities.

Signs & Symptoms of Cavities

If you suspect a cavity, you should visit your dentist as soon as possible, even if it’s in between your routine appointments. The earlier you treat a cavity, the less likely it will be able to cause significant damage.

Here are common symptoms that indicate that a cavity might be getting larger.

Tooth Pain & Toothaches

One of the most frequent signs of a cavity is a toothache. This discomfort can range from mild to severe, lasting anywhere between a few seconds to several minutes at a time. 

In some cases, the pain can extend to your gums, jaw, or even ears. Persistent toothaches and pain should be evaluated by your dentist, as they could be a sign of an underlying cavity.

Sensitivity to Temperature

Unusual sensitivity to hot and cold temperatures could indicate a cavity. When the cavity has penetrated deep into the tooth, it often leaves the nerves exposed, making your teeth more sensitive to temperature changes.

This sensitivity may occur suddenly when consuming hot or cold items, lasting for several seconds, typically affecting one tooth or a particular set of teeth. This sensitivity may also be accompanied by discomfort or pain.

Chronic Bad Breath

Cavities form when bacteria in your mouth break down sugars and produce acids. The same bacteria responsible for cavities also release compounds that cause unpleasant tastes and odours. The longer a cavity goes untreated, the more likely it is to contribute to bad breath.

Swelling or Pus

In the advanced stages of a cavity, swelling or pus in the affected area may be a warning sign. This suggests that the infection has infiltrated the surrounding tissues and could be evolving into an abscess. An abscess demands immediate dental attention.

Cavity Prevention Techniques

Fortunately, there are measures you can adopt to prevent cavities. Maintaining proper oral hygiene is important: brush your teeth twice a day, floss daily, and keep up regular dental checkups.

Reducing your intake of sugary or junk food can also lower your cavity risk. Eat nutrient-rich foods that promote your oral health. 

Fluoride can also help strengthen tooth enamel and make it more resistant to acid attacks. Using fluoridated toothpaste and mouthwash can help prevent cavities.

Responding to a Suspected Cavity

If you notice any signs of dental decay such as unusual discolouration or a hole in your tooth, reach out to your dentist as soon as possible. Timely intervention can prevent further decay and stop the cavity from worsening.

During your dental visit, your dentist will assess your oral health and suggest the best course of treatment. If necessary, they may take an X-ray. 

Fillings are the most common treatment options for cavities, but deeper cavities may require root canal therapy. Additionally, a dentist may recommend dental sealants to prevent future tooth decay.

Regular Dental Visits Paired with Preventive Care

While cavities are common, they’re also preventable. Upholding good oral hygiene can mitigate the risk of developing cavities and other dental complications.
