Dental Fillings

About Dental Fillings:
Dental Fillings in Chatswood are used to repair cavities and restore the strength of damaged teeth. By filling in areas affected by decay, dental fillings help protect your teeth from further damage while maintaining their natural function.
At our dental clinic in Chatswood, we offer a range of filling options, including traditional amalgam as well as tooth-coloured materials such as composite resin and porcelain. These modern materials blend seamlessly with your natural teeth, giving you a healthier and more natural-looking smile.
Depending on the type of material used, dental fillings can last many years — in some cases, over 20 years — making them a reliable solution for long-term oral health.

- Preserve your natural tooth structure.

General FAQs
Dental fillings are restorative treatments that repair damaged or decayed teeth. The dentist removes the compromised tooth material and fills the space with a durable substance. Fillings help restore tooth function, prevent further decay, and maintain overall oral health.
The most common dental fillings are composite (tooth-colored resin), amalgam (silver-colored), gold, ceramic, and glass ionomer. The best option depends on factors like the location of the tooth, aesthetic preferences, durability, and cost.
Dental fillings can last 5 to 30 years, depending on the material used and your oral hygiene habits. Composite (tooth-colored) fillings usually last 5–10 years, amalgam (silver) 10–15 years, gold and ceramic 15–20+ years, and glass ionomer fillings around 3–5 years.
No, dental fillings are usually not painful because the area is numbed with local anesthesia. You may feel pressure or vibration, but not pain. Mild sensitivity or discomfort can occur for a short time after the anesthesia wears off, but it typically subsides within a week or two.
After a filling, avoid hard, sticky, and very hot or cold foods to prevent damage. Maintain good oral hygiene by brushing twice daily and flossing daily. Avoid chewing on the numb side until the anesthesia wears off. If you experience persistent sensitivity, contact your dentist for a follow-up.
