Dental Fillings in Singapore
Dental fillings are commonly used to restore teeth affected by decay, small fractures, or worn areas. By removing the damaged portion of the tooth and rebuilding it with a restorative material, the remaining tooth structure can be protected and supported.
This page explains when dental fillings may be considered, what the procedure typically involves, and how to determine whether a filling or another restoration is more appropriate.
Quick Overview
Dental fillings may be discussed when:
-
Tooth decay is detected
-
A small fracture or chipped area is present
-
An old filling requires replacement
-
Localised sensitivity is linked to structural loss
A filling may not be suitable when:
-
A large portion of the tooth is missing
-
Cracks extend through the cusps
-
The tooth requires root canal treatment
-
Chewing forces exceed what remaining structure can support
What Are Dental Fillings?
A dental filling restores the shape and function of a tooth after damaged or decayed areas are removed. In most modern restorative care, tooth-coloured composite materials are used to bond directly to the remaining tooth structure.
This bonded approach helps reinforce the tooth while preserving as much natural structure as possible.
When Are Dental Fillings Considered?
Tooth Decay
When bacteria weaken the enamel and dentine, the affected area may require removal and restoration. Early intervention helps prevent further structural loss.
Minor Fractures or Chipped Edges
Small fractures or chipped surfaces may be repaired using composite material to restore contour and function.
Replacement of Old Restorations
Existing fillings may wear down, leak, or develop decay underneath. Replacement may be discussed when deterioration is identified during examination.
Types of Dental Filling Materials
Different materials may be used depending on the size of the cavity, location of the tooth, chewing forces, and aesthetic considerations.
Tooth-Coloured Composite Fillings
Tooth-Coloured Composite Fillings
Composite fillings are commonly used in contemporary restorative dentistry. These materials bond directly to the remaining tooth structure and can be shaped to restore both function and natural contour.
Because composite materials bond directly to enamel and dentine, they help restore structural continuity and support the remaining tooth structure while allowing more conservative preparation that preserves healthy enamel and dentine.
Composite restorations are used for a wide range of clinical situations, including both front and back teeth, depending on cavity size, remaining structure, and functional demands.
Their shade can be selected to blend with the surrounding tooth, allowing restoration of both function and appearance.
When shade matching is important, teeth whitening may sometimes be discussed before final restoration placement.
Other Filling Materials
In certain cases, alternative materials may be discussed depending on functional requirements and tooth condition. The choice of material is based on clinical examination and long-term considerations rather than preference alone.
What to Expect During a Dental Filling Procedure
The exact steps vary depending on the size and location of the cavity, but most filling procedures follow a similar sequence.
Assessment and Diagnosis
The tooth is examined clinically and may be evaluated with radiographs to determine the depth and extent of decay.
Removal of Damaged Tooth Structure
The affected enamel and dentine are carefully removed while preserving as much healthy structure as possible.
Placement of the Filling Material
The restorative material is placed in layers and shaped to restore the natural contour of the tooth. It is then hardened and polished to ensure proper bite alignment and surface smoothness.
Local anaesthesia may be used when required to maintain comfort during the procedure.
What to Expect During a Dental Filling Procedure
Some individuals may notice mild sensitivity to cold or pressure following a filling. This is often temporary and typically improves as the tooth settles.
If sensitivity persists or worsens over time, a review may be appropriate to assess bite alignment or underlying factors.
When a Crown May Be Recommended Instead
While dental fillings are suitable for many small to moderate cavities, they may not always provide adequate support when a large portion of the tooth has been lost.
Extensive Loss of Tooth Structure
When decay or fracture has removed a significant amount of enamel and dentine, the remaining tooth walls may be too thin to withstand normal chewing forces. In such cases, a crown may be discussed to provide broader coverage and protection.
Cracks Extending Through Cusps
If cracks involve one or more cusps or if biting causes pain due to structural weakness, a filling alone may not be sufficient. A restoration that covers and stabilises the cusps may be considered.
Root Canal–Treated Teeth
Teeth that have undergone root canal treatment may become more brittle over time, especially if substantial structure has been removed. Depending on the location and remaining tooth structure, a crown or onlay may be discussed to reduce fracture risk.

Frequently Asked Questions (FAQs)
How do I know if I need a dental filling?
A filling may be discussed when decay, structural loss, or a small fracture is identified during examination. Some cavities do not cause pain in the early stages, which is why routine dental check-ups are important for early detection.
Does getting a filling hurt?
Most small to moderate fillings are well tolerated. Local anaesthesia may be used when required to maintain comfort. The level of sensation depends on the depth of decay and the individual’s pain threshold.
How long do dental fillings last?
The lifespan of a filling varies depending on cavity size, chewing forces, oral hygiene, and material used. Regular review appointments help monitor wear or changes over time.
Why does my tooth feel sensitive after a filling?
Mild sensitivity to cold or pressure may occur temporarily after a filling. This often improves as the tooth settles. If discomfort persists or worsens, reassessment may be appropriate.
Do old fillings need to be replaced if they are not causing pain?
Lack of pain does not always mean a filling is functioning well. Fillings may wear down, leak, crack, or develop decay underneath without symptoms. Clinical examination and radiographs help determine whether a restoration remains stable or whether replacement should be considered.
What is the difference between a filling and a crown?
A filling restores a smaller area of damage within the tooth. A crown covers most or all of the tooth when significant structure has been lost. The choice depends on how much healthy tooth remains and how the tooth functions during chewing.
Unsure if a Filling Is Suitable for Your Tooth?
Every tooth is different. A short clinical assessment can help determine whether a filling is appropriate, whether a larger restoration may be required, or whether monitoring is sufficient at this stage.
