When acids and bacteria etch away at our tooth enamel, it demineralises and weakens. Eventually, that weak spot erodes and becomes a cavity. When it does, a small filling is the best way to prevent additional damage and seal out bacteria.
Depending on your cavity size, we may recommend a white (composite) restoration or a traditional amalgam (silver) filling.
White dental fillings are generally more aesthetic and can be placed in various areas of the mouth due to their ability to blend in with the colour of the teeth.
Silver restorations are typically reserved for large cavities or when cost is a factor.
Dental fillings provide several important benefits:
- Prevent further decay and infection
- Restore normal tooth function
- Improve comfort when eating and chewing
- Maintain natural tooth appearance (especially composite fillings)
- Help avoid more complex treatments like root canals or extractions
Not all cavities are painful. Some of the symptoms that you may experience can involve:
During your exam at Ormeau Dental, we’ll take an X-ray of the tooth to evaluate how deep the cavity goes.
As long as it has not yet reached the nerve of the tooth, a filling is usually the most appropriate treatment. Leaving the decay untreated could result in an abscessed tooth and the need for root canal treatment.
When a Filling Is Not Enough
In some cases, a tooth may be too damaged for a simple filling. Alternatives may include:
- Dental crowns for heavily restored or weakened teeth
- Root canal treatment if decay reaches the nerve
- Tooth extraction if the tooth cannot be saved
Early treatment greatly increases the chance of preserving the natural tooth.
When Do You Need a Dental Filling?
A dentist may recommend a filling if you experience or show signs of:
Tooth decay (cavities)
Bacteria in the mouth produce acids that gradually break down tooth enamel, creating small holes known as cavities.
Tooth sensitivity
Sensitivity to hot, cold, or sweet foods can indicate enamel breakdown or exposed dentine.
Visible holes or dark spots
These may indicate decay that requires immediate treatment.
Chipped or worn teeth
Minor fractures or wear from grinding may also be repaired with fillings.
Food trapping or discomfort
Food getting stuck between teeth can sometimes signal a cavity forming between contact points.
Do Dental Fillings Hurt?
Most patients report little to no discomfort during the procedure. Thanks to modern anaesthetics and gentle techniques, the process is typically quick and comfortable.
After the procedure, mild sensitivity may occur for a short time but usually settles within a few days.
How Long Do Dental Fillings Last?
The lifespan of a filling depends on the material used and oral hygiene habits:
- Composite fillings: 5–10 years (often longer with good care)
- Amalgam fillings: 10–15+ years
- Glass ionomer fillings: 5 years or less (depending on location)
Regular dental check-ups help ensure fillings remain in good condition.
Are Dental Fillings Covered by Private Health?
Yes, dental fillings are often covered by private health insurance, but the amount you get back depends on your policy. Dental fillings are usually covered by private health insurance under general dental or “extras” cover, but the rebate depends on your level of cover, annual limits, and waiting periods. Most patients will still have a gap payment, although many health funds offer on-the-spot claiming through HICAPS.
For patients at Ormeau Dental, the exact out-of-pocket cost will vary depending on their health fund and policy.

Treating dental cavities early is crucial to prevent the escalation of oral health issues. Early intervention halts the progression of decay, preserving the tooth’s structure and preventing more invasive, costly treatments in the future.
Left untreated, cavities can deepen, leading to severe toothaches, infections, and potential tooth loss.
Moreover, timely treatment minimizes the risk of bacteria spreading to neighbouring teeth or entering the bloodstream, which could lead to broader health concerns. Addressing cavities promptly ensures optimal oral health, comfort, and overall well-being.
Getting a filling is a routine and generally comfortable procedure.
Step 1: Examination & diagnosis
The dentist examines the tooth and may take X-rays to assess the extent of decay.
Step 2: Local anaesthetic
A local anaesthetic is used to numb the area, ensuring a pain-free experience.
Step 3: Removal of decay
The decayed portion of the tooth is carefully removed.
Step 4: Cleaning the tooth
The area is cleaned to remove bacteria and prepare it for restoration.
Step 5: Filling Placement
The chosen filling material is placed, shaped, and hardened.
Step 6: Polishing & Adjustment
The filling is polished and adjusted to ensure a natural bite and smooth finish.
