How do you remove a cavity?

A dentist removes a cavity by drilling away the decayed portion of the tooth and filling it with dental materials.

Can a cavity heal on its own?

No, a cavity cannot heal on its own. Once tooth decay occurs, it requires professional dental treatment to remove the decayed area and restore the tooth.

What are the 3 types of cavities?

The three types of cavities are pit and fissure cavities (on chewing surfaces), smooth surface cavities (on flat tooth surfaces), and root cavities (on the root surfaces).

How can cavities be treated?

Cavities are treated by removing the decayed portion of the tooth and filling the cavity with dental materials, such as amalgam or composite resin. In advanced cases, root canal therapy or tooth extraction may be necessary.

Can coconut oil remove cavities?

No, coconut oil cannot remove cavities. While coconut oil pulling may have some oral health benefits, it cannot cure or remove cavities. Professional dental treatment is required to address cavities effectively.

How can I fix a cavity at home?

It is not possible to fix a cavity at home. Dental cavities require professional treatment by a dentist to properly remove the decay and restore the tooth.

Can you brush a cavity?

Yes, you should continue to brush your teeth, including the area with a cavity, using a soft-bristled toothbrush. However, brushing alone cannot remove a cavity. Professional dental treatment is necessary to treat cavities effectively.

What is cavity?

A cavity, also known as dental caries or tooth decay, is a common dental condition that occurs when bacteria in the mouth produce acids that erode the hard tissues of the teeth.

It is characterized by the gradual destruction of the tooth structure, resulting in small holes or cavities in the affected tooth. Cavities can develop in various parts of the tooth, including the enamel (outer layer), dentin (middle layer), and potentially reaching the pulp (inner layer) if left untreated.

Cavities are primarily caused by poor oral hygiene practices, such as inadequate brushing and flossing, which allow plaque to accumulate on the teeth. Plaque is a sticky film of bacteria that forms on the teeth and produces acids when exposed to sugars and carbohydrates in the diet.

These acids gradually dissolve the minerals in the tooth enamel, leading to the formation of cavities.

Common symptoms of cavities include toothache, tooth sensitivity to hot, cold, or sweet foods, visible holes or pits in the teeth, and discoloration or staining on the tooth surface. However, in some cases, cavities may not cause noticeable symptoms until they progress and reach a more advanced stage.

Preventing cavities involves practicing good oral hygiene, including regular brushing with fluoride toothpaste, flossing daily, and using mouthwash.

Additionally, limiting the consumption of sugary and acidic foods and beverages, along with regular dental check-ups and professional cleanings, can help in preventing cavities.

If a cavity is detected, it is important to seek dental treatment promptly. The dentist will remove the decayed portion of the tooth and fill the cavity with materials such as dental amalgam, composite resin, or porcelain to restore the tooth’s structure and function.

In more severe cases, when the cavity has affected a significant portion of the tooth or reached the inner layers, additional treatments such as root canal therapy or tooth extraction may be necessary.

Maintaining good oral hygiene practices, adopting a tooth-friendly diet, and seeking regular dental care are crucial for preventing and addressing cavities, promoting overall dental health, and preserving the longevity of your teeth.

Causes of Cavity

The primary cause of cavities, also known as dental caries or tooth decay, is the interaction between bacteria in the mouth and the foods we consume. Here are the key factors that contribute to the development of cavities:

Bacteria: The mouth is home to various types of bacteria, including Streptococcus mutans and Lactobacillus. These bacteria form a sticky film called plaque on the teeth. When plaque is not adequately removed through oral hygiene practices, the bacteria in plaque can produce acids that attack the tooth enamel, leading to decay.

Sugary and Starchy Foods: Bacteria in the mouth feed on sugars and carbohydrates from the foods we eat, especially those that are sticky or remain on the teeth for an extended period. Sugary and starchy foods, such as candies, cookies, cakes, sodas, and chips, provide a food source for the bacteria to produce acids that erode the tooth enamel.

Poor Oral Hygiene: Inadequate oral hygiene practices, including infrequent or improper brushing and flossing, can allow plaque to build up on the teeth. When plaque is not removed effectively, the bacteria have more time to produce acids and cause damage to the teeth.

Dry Mouth: Saliva plays a crucial role in neutralizing acids and remineralizing the tooth enamel. Having a dry mouth, which can be caused by certain medications, medical conditions, or mouth breathing, reduces the protective effect of saliva, making the teeth more susceptible to decay.

Acidic Foods and Beverages: Consuming acidic foods and beverages, such as citrus fruits, tomatoes, vinegar, and carbonated drinks, can erode the tooth enamel, making it more vulnerable to bacterial attacks and cavity formation.

Genetics: Some individuals may be genetically predisposed to having a higher risk of developing cavities. Factors such as tooth structure, enamel strength, saliva composition, and susceptibility to bacterial colonization can be influenced by genetics.

Poorly Formed Tooth Enamel: In some cases, individuals may have naturally weaker or less mineralized tooth enamel, making the teeth more prone to cavity formation.

It’s important to note that cavities are preventable through proper oral hygiene practices, a balanced diet, regular dental check-ups, and professional cleanings. By minimizing the factors that contribute to cavity formation, you can maintain good oral health and reduce the risk of developing cavities.

What are the type of cavity?

Cavities, or dental caries, can manifest in different forms depending on their location and severity. Here are the main types of cavities:

what does a cavity look like
  1. Pit and Fissure Cavities: These cavities form on the chewing surfaces of the teeth, particularly in the grooves and pits that are more prone to trapping food particles and bacteria. They are commonly found on the molars and premolars.
  2. Smooth Surface Cavities: Smooth surface cavities occur on the flat surfaces of the teeth, such as the sides and in between the teeth. They typically develop when plaque accumulates and remains undisturbed due to inadequate oral hygiene practices.
  3. Root Cavities: Root cavities occur on the root surfaces of the teeth, usually in individuals with receding gums or gum disease. The exposed root surfaces are more vulnerable to decay as they lack the protective enamel covering and are composed of a softer material called cementum.
  4. Recurrent Cavities: Recurrent cavities form around the edges or underneath existing dental fillings or crowns. They can develop when bacteria infiltrate the margin between the tooth and the restoration, leading to decay in the surrounding tooth structure.
  5. Early Childhood Cavities (ECC): ECC, also known as baby bottle tooth decay, refers to cavities that occur in infants and young children. It is typically caused by prolonged exposure of the teeth to sugary liquids, such as milk, formula, or juice, especially when consumed from a bottle or sippy cup over an extended period.

ECC is defined as the presence of one or more decayed, missing, or filled tooth surfaces in any primary tooth in a child at 71 months.

The severity of cavities can vary as well, ranging from superficial enamel cavities to deeper cavities that reach the dentin or even the inner pulp of the tooth. Timely detection and treatment of cavities are crucial to prevent further damage and complications.

Regular dental check-ups, including dental X-rays, allow dentists to identify and diagnose cavities at an early stage, enabling prompt treatment and minimizing the extent of decay.

Proper oral hygiene practices, a balanced diet, and preventive measures such as dental sealants and fluoride treatments can help reduce the risk of developing cavities in the first place.

Cavity Symptoms

The symptoms of a cavity can vary depending on the severity and location of the decay. Here are common symptoms associated with cavities:


One of the most common signs of a cavity is a toothache. The pain may be mild initially and worsen over time as the decay progresses. The toothache can be spontaneous or occur when eating or drinking something hot, cold, sweet, or acidic.

Tooth Sensitivity:

Sensitivity to hot, cold, sweet, or acidic foods and beverages is often experienced when a cavity is present. The sensitivity may be localized to a specific tooth or area of the mouth.

Visible Holes or Pits:

As a cavity progresses, it can create visible holes, pits, or dark spots on the affected tooth. These areas may appear discolored, brown, or black.

Tooth Discoloration:

Cavities can cause the affected tooth to become discolored. The discoloration may be white, brown, or black, depending on the extent of the decay.

Tooth Fractures:

In some cases, cavities can weaken the tooth structure, leading to fractures or breakage of the affected tooth. This can result in sharp edges or rough surfaces.

Bad Breath:

Decay-causing bacteria can produce foul-smelling byproducts, leading to persistent bad breath or an unpleasant taste in the mouth.

Pus or Abscess:

In advanced cases, a cavity can lead to an infection in the tooth or surrounding gum tissue. This can result in the formation of a pus-filled pocket or abscess, accompanied by severe pain, swelling, and an overall feeling of illness.

It’s important to note that not all cavities cause noticeable symptoms in the early stages. Regular dental check-ups are crucial for detecting and diagnosing cavities before they progress and cause significant discomfort or complications.

If you experience any of these symptoms or suspect you may have a cavity, it is important to schedule an appointment with a dentist for a thorough examination and appropriate treatment.

Can cavities be cured?

Yes, cavities can be treated and cured. The decayed portion of the tooth is removed by a dentist, and the cavity is filled with dental materials like amalgam or composite resin. In advanced cases, a root canal or tooth extraction may be necessary.

Proper oral hygiene, regular dental check-ups, and preventive measures can help prevent cavities and maintain dental health.

Cavity Treatment: how to get rid of a cavity?

To get rid of a cavity and treat tooth decay, the following steps are typically involved:

  1. Dental Examination: Visit a dentist for a thorough examination, including dental X-rays, to assess the extent and severity of the cavity.
  2. Anesthesia: Before the treatment begins, the dentist may administer local anesthesia to numb the area around the affected tooth, ensuring a comfortable procedure.
  3. Decay Removal: Using a dental drill, the dentist will remove the decayed portion of the tooth, including the affected enamel, dentin, and any compromised tissue.
  4. Tooth Preparation: The remaining tooth structure is prepared to create a clean and stable foundation for the dental restoration.
  5. Dental Filling: The cavity is filled with a suitable dental material, such as dental amalgam (silver fillings) or tooth-colored composite resin. The chosen material is shaped, contoured, and hardened using specialized techniques.
  6. Bite Adjustment: The dentist will check and adjust the bite to ensure proper alignment and occlusion with the opposing teeth.
  7. Polishing: The filled tooth is polished to provide a smooth and natural appearance.

For more extensive decay or if the cavity has reached the inner pulp of the tooth, additional treatment options may be necessary, such as:

  • Root Canal Therapy: If the pulp is infected or damaged, a root canal procedure may be performed. This involves removing the infected pulp, disinfecting the root canals, and filling them with a biocompatible material. The tooth is then sealed and often restored with a dental crown.
  • Tooth Extraction: In severe cases where the tooth is extensively damaged and cannot be restored, extraction may be necessary. The extracted tooth can be replaced with options like dental implants, bridges, or dentures.

It’s important to note that early detection and treatment of cavities are essential to prevent further damage and complications. Maintaining good oral hygiene practices, including regular brushing, flossing, and dental check-ups, can help prevent cavities and maintain overall dental health.

How can I reduce my cavity naturally?

While it’s not possible to completely reverse a cavity without professional dental intervention, there are natural strategies you can adopt to help reduce the risk of cavities and promote dental health. Here are some tips:

Maintain Good Oral Hygiene: Brush your teeth at least twice a day using fluoride toothpaste and a soft-bristled toothbrush. Make sure to clean all tooth surfaces and along the gumline. Additionally, floss daily to remove plaque and food particles from between the teeth.

Limit Sugary Foods and Drinks: Reduce your consumption of sugary and acidic foods and beverages, as they contribute to tooth decay. Opt for healthier snack options like fresh fruits and vegetables and choose water or unsweetened drinks instead of sugary sodas or juices.

Increase Water Intake: Drinking water throughout the day helps rinse away food particles and neutralize acids in the mouth. It also helps maintain saliva production, which aids in protecting the teeth against cavities.

Consume Tooth-Friendly Foods: Incorporate foods that promote dental health into your diet. Foods rich in calcium, such as dairy products, leafy greens, and almonds, help strengthen tooth enamel. Crunchy fruits and vegetables, like apples and carrots, can help clean the teeth naturally.

Use Fluoride Products: Fluoride strengthens tooth enamel and makes it more resistant to decay. Use fluoride toothpaste and consider using a fluoride mouthwash as part of your oral care routine.

Chew Sugar-Free Gum: Chewing sugar-free gum after meals stimulates saliva production, which helps wash away food particles and neutralize acids in the mouth.

Consider Natural Remedies: Some natural remedies may offer additional support for dental health. For example, rinsing with diluted hydrogen peroxide or using mouthwash containing tea tree oil or xylitol may help inhibit bacterial growth.

Remember, while these natural strategies can contribute to maintaining dental health, they should not replace regular dental check-ups and professional treatments. It’s essential to consult with a dentist for a comprehensive evaluation, personalized advice, and appropriate dental care to address cavities and ensure optimal oral health.
