What is a Cavity?

A cavity, also known as tooth decay, is a damaged area on the hard surface of teeth. It is caused by bacteria in your mouth producing acid that erodes tooth enamel. Cavities can start as tiny holes and grow larger if untreated, potentially leading to severe toothache, infection, and even tooth loss.

How Cavities Form

Cavities form through a process involving:

  1.  Plaque Formation: Plaque is a sticky film of bacteria that constantly forms on your teeth.
  2.  Acid Production: When you consume sugary or starchy foods, the bacteria in plaque produce acids.
  3. Enamel Erosion: The acids erode the enamel, creating small holes or cavities.
  4. Progression: Without treatment, the cavity can deepen, reaching the tooth’s inner layers.

Symptoms of Cavities

  • Toothache
  • Sensitivity to hot, cold, or sweet foods
  • Visible holes or pits in your teeth
  • Brown, black, or white staining on any surface of a tooth

What is a Filling?

A filling is a treatment used to restore the function and integrity of a tooth damaged by decay. The process involves removing the decayed material and filling the cavity with a suitable material.

Types of Filling Materials

  1. Amalgam Fillings: Made from a mixture of metals, these are known for their durability and are typically used for back teeth.
  2. Composite Fillings: Made from a resin that can match your teeth’ colour, these are often used for visible areas.
  3. Gold Fillings: Durable and long-lasting, but more expensive and less common.
  4. Ceramic Fillings: Made of porcelain, these are also tooth-coloured and more resistant to staining.

The Filling Procedure

  1. Examination: Your dentist examines the tooth and decides on the best course of treatment.
  2. Anesthesia: Local anaesthesia is applied to numb the area around the affected tooth.
  3. Decay Removal: The decayed area is removed using a drill or laser.
  4. Cleaning: The cavity is cleaned to remove bacteria and debris.
  5. Filling: The chosen filling material is applied in layers and shaped to fit the tooth.
  6. Polishing: The filling is polished to match the tooth’s surface.

Benefits of Fillings

  • Restore tooth function
  • Prevent further decay
  • Improve the tooth’s appearance (especially with composite fillings)

What are Dental Sealants?

Dental sealants are a preventive treatment designed to protect teeth from cavities. They are thin, plastic coatings applied to the chewing surfaces of the back teeth (molars and premolars), where decay is most likely to occur.

How Sealants Work

  1. Blocking Food and Bacteria: Sealants fill the grooves and pits in the teeth, creating a smooth surface that is less likely to harbour food and bacteria.
  2. Long-lasting Protection: Sealants can protect teeth for several years but must be checked regularly for wear and tear.

The Sealant Application Process

  1. Cleaning: The tooth is thoroughly cleaned and dried.
  2. Etching: An acidic solution is applied to roughen the surface, allowing the Sealant to bond better.
  3. Rinsing and Drying: The tooth is rinsed and dried again.
  4. Applying Sealant: The Sealant is painted onto the tooth enamel and hardened with a special light.

Benefits of Sealants

  • Effective in preventing cavities
  • Quick and painless application
  • Durable protection for back teeth
  • Ideal for children and teenagers, who are particularly prone to cavities

Comparing Cavities, Fillings, and Sealants

Cavities are the problem, and fillings are the solution. When a cavity forms, a filling is used to repair the damage and restore the tooth. In essence, fillings are a response to decay that has already occurred.

Role of Sealants in Preventive Care

Sealants, on the other hand, are all about prevention. They are applied before cavities form, providing a protective barrier that helps to prevent decay. Sealants are particularly useful for children but can also benefit adults.

Why All Three Are Essential

  1. Cavities: Identifying and treating cavities early can prevent more serious dental issues.
  2. Fillings: Fillings restore the health and function of teeth damaged by cavities, preventing further decay.
  3. Sealants: Sealants offer a proactive approach to oral health, protecting teeth from cavities before they start.

Final thoughts

Understanding the differences between cavities, fillings, and dental sealants is crucial for maintaining good oral health. Cavities indicate damage that needs repairing with fillings, while sealants provide preventive care to stop cavities from forming in the first place.
