Dental crowns and fillings are two of the most common treatments used to repair damaged or decayed teeth. While both serve to restore a tooth’s strength and function, they do so in very different ways. If you’re wondering which option is right for you, understanding the difference can make your next dental appointment a lot easier.
A filling is used to repair a tooth that has been affected by decay or minor damage. Your dentist removes the decayed area and fills the space with a material such as composite resin. This restores the tooth’s structure and prevents further decay.
Fillings are usually quick to complete and are most effective when the damage is relatively small. They’re a routine part of general dentistry and are typically completed in a single visit.
A dental crown is used when a tooth is more severely weakened—either due to extensive decay, a large filling that needs replacing or after root canal treatment. A crown is essentially a cap that covers the entire tooth, restoring both appearance and strength.
The crown is custom-made to match the shape and colour of your natural teeth, so it fits in seamlessly. It’s designed to last longer and take on more pressure than a filling, making it ideal for molars or teeth that do a lot of chewing.
A filling can usually be done in one appointment and often takes less than an hour. After removing the decay, the dentist places and shapes the material before it sets. Crowns, however, require more preparation. At the first visit, the tooth is reshaped and impressions are taken. A temporary crown is fitted while the permanent one is being made. Once ready, you’ll return for a second appointment to have the final crown placed.
Fillings do a great job of restoring function and preventing further decay but they don’t offer the same level of strength as a crown. They can last five to ten years with proper care but may need replacing if they chip, crack or begin to wear. Crowns are a longer-term solution. Depending on the material used and how well they’re maintained, crowns can last between ten and fifteen years—or even longer in some cases.
Fillings are generally more affordable, especially if you catch decay early. They’re a cost-effective solution for minor repairs and often covered under standard dental plans. Crowns are more expensive because they involve more work, both in terms of materials and time. However, when a tooth needs more structural support, a crown can prevent future issues—making it a worthwhile investment in the long run.
Composite fillings are colour-matched to your teeth and almost invisible, making them a good option for visible areas. Crowns also come in a range of materials including porcelain, ceramic and metal, each with their own benefits. Porcelain crowns, for instance, are highly natural-looking and are often chosen for front teeth.
Metal crowns, while not as discreet, are extremely durable and a reliable option for back teeth. Your dentist will talk you through the best material based on where the crown is being placed and your overall dental needs.
This comes down to the extent of the damage. For small cavities or minor cracks, a filling is usually the best approach. It’s simple, cost-effective and retains more of your natural tooth. If the tooth is heavily filled, cracked or has had root canal treatment, a crown is often the better choice. It offers extra support and long-term protection that a filling alone can’t provide.
With fillings, there might be slight sensitivity for a day or two but it usually settles quickly. After a crown, your tooth may feel a little different for a few days, especially while adjusting to the new bite. Any mild discomfort tends to fade as the tooth settles into its new shape. Either way, maintaining good oral hygiene is key. Brush twice daily, floss regularly and avoid biting hard foods that could damage the restoration.
There’s no one-size-fits-all when it comes to restoring teeth, which is why your dentist will always assess the situation before recommending a filling or a dental crown. The decision depends on the condition of the tooth, your oral health and how long you want the solution to last.
