Dental Crowns

If you damage your teeth, your dentist can use a dental crown to restore its function, appearance, and shape. You may require a crown under various circumstances such as when you have a broken tooth, a huge filling in your tooth, and a root canal. This hollow and artificial tooth can also cover a decayed or discolored tooth and protects your tooth against further damage. Crowns are frequently necessary when a huge cavity threatens the current health of your tooth. Dentists usually bond dental crowns to your tooth using dental cement. While beneficial to your dental health, the materials and procedure can be relatively costly.

 

When a dental crown is necessary

Various situations require tooth restoration with a crown. They include:

 

Large filling

At times, a large filling requires replacement with a crown because your tooth shows signs of cracks and stress around the filling.

 

Undesirable tooth appearance

Crowns can make your teeth appear beautiful and natural if they have an undesirable appearance because of shape, color, or spaces between your teeth.

 

Root Canal

This treatment leaves your tooth hollow and predisposes the remaining part to cracking. Therefore, a tooth that has undergone root canal frequently needs restoration with a dental crown to prevent fracture.

 

Types of Crowns

Crowns originate from various materials. Depending on the tooth that requires a crown, your dentist will recommend a material or blend of materials that suit you.

 

Metal

These crowns are generally durable and will not break or chip. They also endure chewing and biting forces well. The major drawback is the metallic color especially gold, which looks artificial especially on your front teeth.

 

Porcelain

These crowns appear very natural and are more brittle compared to composite or metal crowns. They are also prone to chipping. Due to this factor, dentists will not place them on your back teeth.

 

Composite

These crowns appear natural and will not chip easily as porcelain crowns do. However, they typically wear more rapidly from chewing. Brushing your teeth tends to eliminate the polished surface of these crowns, causing them to stain easily.

 

All-resin

These crowns are more affordable than other types of crowns. However, they erode over time and tend to fracture easily than porcelain-fused-to-metal crowns.

 

Porcelain-fused-to-metal crowns

These crowns appear natural and are more durable than composite or porcelain crowns. They will not chip as easily as ceramic and porcelain crowns do. However, the metal may be visible if your gums shrink.

 

Crowns are strong and typically last for approximately 10 years or longer if you care for them. It is important to floss and brush your crown as you would your natural teeth.
