Dental fillings are one of the most common restorative dental treatments used to repair teeth damaged by decay, cracks or wear. They restore tooth structure, improve function and prevent further damage — helping you maintain a healthy, confident smile.
If you have a cavity, chipped tooth or worn enamel, understanding the types of dental fillings, the procedure and aftercare will help you make informed decisions about your treatment.
What Is a Dental Filling?
A dental filling is a material placed inside a damaged tooth to restore its shape, function and integrity. It seals the area where bacteria could enter, preventing further decay.
According to the research, fillings can last from 5 to 15 years or longer, depending on the material used, your oral hygiene habits and dietary factors.
Common Reasons for Dental Fillings
- Cavities (tooth decay) caused by plaque and bacteria
- Chipped or broken teeth from trauma or biting hard objects
- Worn down teeth due to grinding (bruxism) or acid erosion
- Replacing old fillings that are cracked, loose or leaking
Types of Dental Fillings
There is no one-size-fits-all option — your dentist will recommend the best type based on tooth location, budget and cosmetic preference.
1. Composite Resin Fillings
- Appearance: Tooth-coloured, blends naturally with teeth
- Best for: Front teeth or visible areas
- Pros: Aesthetic, bonds directly to tooth structure
- Cons: Less durable for large cavities, may stain over time
2. Amalgam Fillings (Silver Fillings)
- Appearance: Silver/metallic
- Best for: Back molars where chewing force is greatest
- Pros: Strong, long-lasting (10–15+ years), cost-effective
- Cons: Visible, contains mercury
3. Gold Fillings
- Appearance: Gold metallic
- Pros: Extremely durable (lasts 20+ years), gentle on surrounding teeth
- Cons: Expensive, noticeable in the mouth
4. Ceramic (Porcelain) Fillings
- Appearance: Tooth-coloured, stain-resistant
- Pros: Aesthetic and durable
- Cons: Higher cost, can be brittle if not well-fitted
5. Glass Ionomer Fillings
- Appearance: Tooth-coloured (less aesthetic than composite)
- Pros: Releases fluoride, helps protect against further decay
- Cons: Lower durability, usually used for children’s teeth or non-biting surfaces
Dental Filling Procedure: Step-by-Step
- Examination and Diagnosis – Dentist checks tooth with X-rays if needed
- Anaesthesia – Local numbing to ensure comfort
- Decay Removal – Damaged tooth structure is cleaned
- Tooth Preparation – Surface is shaped for the filling material
- Placement of Filling – Material is applied and hardened (light-curing for composites)
- Shaping and Polishing – Filling is adjusted for bite and smoothed
notes that a single filling typically takes 20–60 minutes, depending on size and location.
Aftercare Tips for Dental Fillings
- Avoid chewing hard or sticky foods for a few hours after placement
- Maintain good oral hygiene — brush twice daily, floss once a day
- Visit your dentist for regular check-ups
- Report any sensitivity, sharp edges or discomfort immediately
How Long Do Dental Fillings Last?
- Composite fillings: 5–7 years
- Amalgam fillings: 10–15 years
- Gold fillings: 20+ years
- Ceramic fillings: Around 15 years
Longevity depends on the filling type, oral hygiene, diet and whether you grind your teeth.
