If you have a cavity or weakened tooth, it’s likely that your dentist in DuPont would recommend either a dental filling or crown, or maybe even both. While these treatments are similar, they are used to address different concerns. Read on to learn more about the difference between fillings and crowns and how to tell what procedure you could need.

What’s the Difference Between a Filling and a Crown?

The best way to determine what dental treatment you need is to visit a dentist for a thorough evaluation. Based on any X-rays or scans they take, as well as their visual exam, they may recommend restorative procedures, such as a filling or crown.

Fillings are sculpted in the treatment chair using a composite resin material to fill in and seal off teeth affected by decay. On the other hand, dental crowns are custom-made in a laboratory and designed to fit over the visible surface of a tooth, covering it completely and providing it with an added layer of protection.

When are Fillings the Best Option?

Fillings are usually recommended when there are no cracks in a tooth and it still has most of its dental structure. You can think of it as a less extensive protective measure for a tooth, like a minor repair versus a remodel. The procedure tends to take less time and be more cost-effective due to the fact that it can be completed at the dental office.

When are Crowns the Best Option?

On the other hand, your dentist may recommend a crown. This process typically takes longer and requires multiple steps, so you can expect it to be more costly than a filling. However, it also tends to treat more extensive dental health concerns, like weakened, cracked, and misshapen teeth. These also tend to last a bit longer than dental fillings, as they’re custom-designed for your tooth by a lab technician.

When are Both Necessary?

In some cases, both a filling and crown may be necessary. This is usually recommended when decay has progressed and a large filling is needed. To help keep the filling in place and protect the tooth, your dentist can also place a dental crown over the top of the tooth.

Deciding the Best Course of Action for You

The best way to learn what type of dental restoration is right for you is to schedule a consultation with your dentist. They will determine the underlying cause of your symptoms and go over the pros and cons of each of your treatment options with you. That way, you can make a confident and informed decision for your oral health.
