If you’ve recently visited your dentist and been told you need either a filling or a crown, you might be wondering what the difference is between these two treatments. Both are common procedures, but they serve different purposes depending on the condition of your tooth. At Medivance Dental, we believe in providing clear, concise information to help you make informed decisions about your oral health. In this blog, we’ll explain the key differences between fillings and crowns, and how our dental clinic in Perth can help determine which one is right for you.
What Is a Dental Filling?
A dental filling is a procedure used to restore a tooth that has been damaged by decay. When a cavity forms, the decayed part of the tooth is removed, and the space is filled with a material to restore the tooth’s shape and function.
When Are Fillings Needed?
Fillings are typically recommended when:
- You have a small to moderate cavity that only affects the tooth enamel (the outer layer of the tooth).
- The tooth is still structurally sound and doesn’t need additional support.
Types of Filling Materials:
There are several different materials used for fillings, including:
- Amalgam Fillings (Silver Fillings): These are durable and cost-effective, often used for back teeth where strength is important.
- Composite Fillings (Tooth-Coloured Fillings): These are more aesthetically pleasing as they blend with the natural colour of your teeth. They’re commonly used for visible teeth, such as those in the front of your mouth.
- Ceramic Fillings: Made from porcelain, these fillings are also tooth-coloured and highly durable, offering a more aesthetic option than amalgam.
- Glass Ionomer Fillings: These are typically used for smaller cavities or in areas where a cosmetic result is less important.
Fillings can be completed in a single visit, and the procedure is relatively simple and non-invasive.
What Is a Dental Crown?
A dental crown, also known as a cap, is a restorative treatment used to cover and protect a tooth that has been significantly weakened or damaged. Crowns are custom-made to fit the tooth perfectly, providing strength, protection, and improved appearance.
When Are Crowns Needed?
Crowns are recommended in the following situations:
- A large portion of the tooth is missing (due to decay or damage).
- The tooth is weak or cracked and needs additional support to prevent further damage.
- You’ve had a root canal and need a crown to restore the tooth’s structure and function.
- Cosmetic reasons, when a tooth is severely discoloured, misshapen, or too worn down.
Types of Crown Materials:
Crowns come in a variety of materials, depending on the location of the tooth and the patient’s preference:
- Porcelain Crowns: These crowns are tooth-coloured, making them ideal for front teeth and visible areas. They offer a natural appearance but may not be as durable as metal crowns.
- Porcelain-Fused-to-Metal Crowns: These combine the strength of metal with the cosmetic benefits of porcelain, making them ideal for back teeth.
- Metal Crowns: Made from alloys like gold or silver, these crowns are highly durable and often used for molars where appearance is less of a concern.
- Zirconia Crowns: These crowns are strong, durable, and tooth-coloured, making them a popular choice for both front and back teeth.
Key Differences Between Fillings and Crowns:
| Aspect | Filling | Crown |
| Used For | Small to moderate cavities | Large cavities, cracked, or damaged teeth |
| Procedure Time | Completed in one visit | Requires two visits (one for the prep and impressions, another for placement) |
| Amount of Tooth Removed | Minimal tooth structure removed | Significant amount of tooth removed to fit the crown |
| Cost | Generally less expensive | More expensive due to custom fabrication |
| Durability | Good for small cavities, may need replacement in 5-10 years | Highly durable, lasting 10-15 years or more |
| Aesthetic Appeal | Tooth-coloured fillings available | Tooth-coloured crowns available, more visible in front teeth |
| Coverage | Only covers the decayed portion of the tooth | Covers the entire tooth, offering more support |
When Should You Choose a Filling vs. a Crown?
Choosing between a filling and a crown depends on the extent of the damage to your tooth. If your tooth is relatively intact and only has a small cavity, a filling is often the best option. However, if your tooth is severely damaged or weakened, a crown may be necessary to protect and restore the tooth to its original strength.
Conclusion:
Both fillings and crowns are effective ways to restore your teeth, but choosing the right treatment depends on the severity of the damage.

FAQs:
- How do I know if I need a filling or a crown?
Fillings are ideal for small cavities or minor damage. A crown is recommended if a tooth is severely decayed, cracked, or weakened and needs more protection. - Is a crown more expensive than a filling?
Yes. Crowns are more complex and typically cost more than fillings. However, they last longer and provide more coverage and strength to the tooth. - Can a filling turn into a crown later?
Yes. If a tooth with a filling suffers further decay or damage, your dentist may recommend upgrading it to a crown for better support and longevity. - How long do crowns and fillings last?
Fillings can last 5–10 years, while crowns can last 10–15 years or more with proper care, depending on the material and your oral hygiene. - Will getting a crown or filling hurt?
No need to worry—your dentist will use local anaesthesia to ensure you’re comfortable. Some mild soreness afterward is normal and temporary.
