What are Dental Crowns and Fillings?

Both fillings and crowns are dental restorations used to fix specific problems. Dental fillings are typically used to patch up minor damages like cavities, small cracks, or chips on teeth.

Fillings are particularly effective when the damage is limited to a specific spot. Crowns, on the other hand, are used for more significant problems, such as large cavities and weak or cracked teeth. 

Crowns are also used to protect teeth after root canals. In some cases, crowns can improve the appearance of misshapen or severely discolored teeth. 

What’s the Difference Between Dental Crowns and FIllings?

Should You Get Crowns and Fillings?

If you’re worried about choosing between fillings or crowns, don’t be. Your dentist will recommend the most effective solution for your situation. 

However, it’s good to know some factors you should consider before choosing which procedure is best for you:

  • Location ⁠ Crowns are better for teeth that take a lot of force, like molars and premolars. On the other hand, fillings might be better for front or visible teeth if the damage isn’t too bad. 
  • The extent of the damage — As mentioned before, fillings are used for small damages, and crowns are used for bigger ones. 
  • Cosmetic reasons — If you want a more natural appearance, you might want to consider fillings.
  • Price — Fillings are generally less expensive, but sometimes metal crowns are cheaper than porcelain ones.
  • Durability — Crowns generally last longer than fillings. They’re a good investment if the tooth has already had extensive work done.

Additionally, you might want to consider fillings to conserve as much of your original tooth as possible because crowns need more tooth structure to remove. If you grind your teeth, your dentist might recommend a crown to protect your teeth in the long run.

The Dental Crown and Filling Procedures

Fillings are typically done in one visit, while dental crowns often require two appointments. However, with advanced technology like CEREC, some dentists can make crowns in one visit.

The procedure for fillings is simple. It involves cleaning, filling, and polishing. On the other hand, crowns take several steps, which include:

  • Preparation and impressions ⁠— Your dentist shapes the tooth to make room for the crown and takes dental molds (or digital scans) to make a model of your crown. This is typically done on the first visit.
  • Temporary protection — You get a temporary crown while your permanent one is being made off-site.
  • Lab time — The molds are sent to a lab, where your crown is carefully made.
  • Final fitting — The permanent crown is placed and adjusted for a perfect fit on your second visit.

Understanding the procedures for each option can help you prepare for what to expect during your appointment. It can also help your dentist determine which option is best for you.

What Materials Are Crowns and Fillings Made of?

In some cases, dental crowns can be made with porcelain or ceramic, which makes them look more natural. They can also be made out of more durable metal alloys. 

However, porcelain-fused-to-metal crowns combine strength with a more natural appearance. Meanwhile, fillings can be made of amalgam (silver) and composite resins. 

The former is more durable but noticeable, but the latter seamlessly blends with your teeth. Additionally, fillings can be made from gold, ceramic, or glass ionomer for specific needs.

Pros and Cons of Dental Crowns and Fillings

Both fillings and crowns effectively protect teeth. However, they each have their own pros and cons. 

Here’s a breakdown of each to help you understand what might be better for you:

It’s important to understand that crowns can have potential risks. After the tooth is prepared, it can become sensitive or even require a root canal. Similarly, you might feel some sensitivity after getting a filling, especially with composite fillings.

How to Take Care of Your Teeth After Crowns or Fillings

If you have a crown or filling, it’s important to ensure your investment lasts. Here are some things you can do to maintain your smile:

  • Avoid abrasive toothpaste to prevent damaging your crown or filling
  • Brush at least twice a day for two minutes
  • Floss regularly
  • Use a mouthguard if you play sports
  • Avoid chewing on hard foods and surfaces
  • Visit your dentist regularly

You should also talk to your dentist about odd sensations, such as pain, sensitivity, loose crowns or fillings, or changes in your bite. Your dentist might have to adjust your crown or filling as needed.

Additionally, both crowns and fillings may need attention or replacement. That’s why regular checkups and proper care are important in maintaining oral health.
