Cavities and damaged teeth are common reasons why people visit the dentist, but understanding the right treatment can sometimes be confusing. Two of the most common restorative dental procedures are cavity fillings and dental crowns. Both have distinct purposes, benefits, and ideal situations where one makes more sense than the other. Here’s what you need to know to make an informed decision about your dental care.
What Is a Cavity Filling?
A cavity filling is a restorative treatment used to repair minor to moderate tooth decay. When plaque and bacteria erode your tooth enamel, they create tiny holes (cavities). Your dentist removes the decayed portion of the tooth and fills it with a material like composite resin, amalgam, gold, or porcelain. This seals the tooth and prevents further decay.
Benefits of Cavity Fillings
- Quick procedure: Typically completed in one visit.
- Minimally invasive: Requires less removal of healthy tooth structure.
- Cost-effective: Less expensive than crowns.
- Aesthetic options: Tooth-colored composite resin blends with natural teeth.
What Is a Dental Crown?
A dental crown (or “cap”) covers the entire visible part of a tooth. Crowns are used when a tooth is severely decayed, weakened, cracked, or after a root canal. The dentist reshapes the tooth and places a custom-made crown over it to restore its shape, strength, and appearance.
Benefits of Dental Crowns
- Protects weakened teeth: Provides full coverage and strength.
- Restores functionality: Allows normal biting and chewing.
- Long-lasting: Durable and resistant to wear.
- Aesthetic: Porcelain and ceramic crowns look like natural teeth.
When Do You Need a Filling?
A filling is ideal if:
- You have a small to medium-sized cavity.
- The tooth structure is mostly intact.
- There’s no significant fracture or deep decay.
- The tooth hasn’t undergone root canal treatment.
Signs you might need a filling include:
- Sensitivity to hot, cold, or sweet foods.
- Visible dark spots or holes in teeth.
- Mild toothache.
- Food consistently getting stuck in certain areas.
When Do You Need a Crown?
A crown is necessary when:
- The cavity is too large for a filling to hold.
- The tooth is cracked, fractured, or severely worn.
- You’ve had a root canal (which weakens the tooth).
- A large filling has failed or repeatedly cracked.
- The tooth’s structure is compromised and needs reinforcement.
Signs you might need a crown:
- Severe toothache or sharp pain when chewing.
- A large portion of tooth structure is missing.
- Existing filling keeps breaking.
- A visibly cracked tooth.
Why Not Always Choose the Less Invasive Filling?
While fillings are less invasive and cheaper, they can fail if the tooth damage is extensive. Placing a filling in a tooth that lacks sufficient healthy structure can result in fracture or leakage over time. A crown, in these cases, offers better long-term stability and protection.
Can You Upgrade from a Filling to a Crown Later?
Yes. Many patients start with a filling, and if the tooth deteriorates or cracks in the future, a crown may be recommended. Regular dental checkups allow your dentist to monitor existing fillings and recommend timely upgrades.
Material Choices: Fillings vs. Crowns
- Fillings: Composite resin (tooth-colored), amalgam (silver), gold, or porcelain.
- Crowns: Porcelain, ceramic, porcelain-fused-to-metal, gold, or zirconia.
Your dentist will suggest the best material based on location, appearance, and durability.
The Bottom Line
Choosing between a cavity filling and a dental crown comes down to the extent of the damage. Minor decay? A filling should suffice. Significant damage or weakened tooth? A crown offers long-term protection.
