How Do Dental Fillings Protect Your Teeth?

Dental fillings are crucial for maintaining oral health. They repair cavities, prevent further decay, and restore tooth structure. At SmileWorks Dental—Kensington, we use safe and durable materials to ensure your teeth remain strong and functional.

If left untreated, cavities can grow, leading to more severe dental problems, including infections and tooth loss. A dental filling helps seal a tooth’s damaged area, preventing bacteria from causing additional harm.

The Importance of Dental Fillings

Dental fillings serve multiple protective functions:

1. Sealing Cavities – Prevents bacteria and food particles from entering the tooth.
2. Restoring Strength – Reinforces the tooth structure, making it functional for chewing.
3. Preventing Further Decay – Stops cavity progression and reduces the need for extensive treatment.
4. Minimising Sensitivity – Helps reduce discomfort caused by enamel wear.
5. Enhancing Aesthetics – Modern fillings blend naturally with your teeth, maintaining a seamless appearance.
6. Preventing Infections – Reduces the risk of bacterial infiltration into the deeper layers of the tooth.
7. Supporting Adjacent Teeth – Prevents neighbouring teeth from shifting or developing cavities due to gaps left by decay.

How Cavities Develop and Why Fillings Are Necessary

Cavities develop due to plaque build-up, which contains acid-producing bacteria. These acids erode the enamel, creating holes in the tooth structure.

Factors Contributing to Tooth Decay

Contributing Factor	How It Affects Teeth
Poor Oral Hygiene	Allows plaque and bacteria to thrive.
High Sugar Intake	Feeds harmful bacteria, accelerating decay.
Acidic Foods & Drinks	Weakens enamel, making teeth more vulnerable.
Dry Mouth	Reduces saliva production, leading to bacterial growth.
Lack of Dental Check-Ups	Prevents early detection and intervention.
Smoking and Alcohol	Increases the risk of enamel damage and gum disease.

Without intervention, cavities grow deeper, reaching the inner layers of the tooth. A filling is essential to stop decay before progressing to more severe conditions like infections or abscesses.

Types of Dental Fillings

The choice of filling material depends on various factors, including durability, aesthetics, and location of the tooth.

Comparison of Dental Filling Materials

Filling Type	Durability	Appearance	Best For
Composite Resin	Moderate	Tooth-coloured	Front teeth & visible areas
Amalgam	High	Silver-coloured	Molars & high-pressure areas
Glass Ionomer	Moderate	Tooth-coloured	Small cavities & children’s teeth
Ceramic	High	Natural-looking	Large fillings & visible teeth
Gold	Very High	Metallic	Longevity & durability in molars

At SmileWorks Dental – Kensington, we carefully select the most suitable material based on your dental needs, ensuring optimal function and aesthetics.

The Dental Filling Procedure

1. Examination & Diagnosis – The dentist assesses the cavity using X-rays if necessary.
2. Anaesthesia – A local anaesthetic numbs the area to ensure comfort.
3. Tooth Preparation – Decayed parts of the tooth are removed.
4. Filling Application – The selected material is placed and shaped to match the natural tooth structure.
5. Final Adjustments – The filling is polished, ensuring a smooth and comfortable bite.
6. Post-Treatment Care – Patients receive guidelines on oral hygiene and dietary recommendations.

This straightforward procedure helps restore dental function while preventing complications.

How Fillings Protect Your Teeth Long-Term

A properly placed dental filling offers long-lasting protection by:

• Reinforcing weakened tooth structure.
• Preventing bacteria from infiltrating cracks or openings.
• Reducing sensitivity by covering exposed dentin.
• Maintaining a natural bite to prevent uneven wear on surrounding teeth.
• Helping preserve the natural shape of the tooth and preventing further damage.

However, regular dental visits are essential to monitor the condition of fillings and ensure their longevity.

Caring for Your Dental Fillings

To extend the lifespan of your fillings and protect your teeth, follow these best practices:

Care Tips	Benefits
Brush twice daily with fluoride toothpaste	Strengthens enamel and prevents decay.
Floss daily	Removes plaque between teeth and around fillings.
Limit sugary and acidic foods	Reduces bacterial growth and enamel erosion.
Avoid chewing hard foods	Prevents filling damage or fractures.
Schedule regular check-ups	Detects early signs of wear or deterioration.
Use a mouthguard if grinding teeth	Protects fillings and prevents cracks.
Rinse with fluoride mouthwash	Strengthens enamel and provides extra protection.

Fillings can last many years with proper care, but occasional replacements may be necessary due to natural wear.

When Should You Replace a Filling?

While dental fillings are durable, they do not last indefinitely. Signs that indicate a replacement is needed include:

• Pain or Sensitivity – May suggest a worn or cracked filling.
• Visible Cracks or Wear – Indicates potential damage to the filling.
• Rough or Uneven Surface – Can affect your bite and comfort.
• Decay Around the Filling – Requires immediate attention to prevent further complications.
• Discolouration or Staining – Some materials, like composite resin, may stain over time.
• Filling Falling Out – A lost filling exposes the tooth to bacteria and decay.

If you experience any of these symptoms, visiting SmileWorks Dental – Kensington for an assessment can prevent more extensive dental issues.
