A crown (or cap) is a covering that encases the entire tooth surface restoring it to its original shape and size. A crown protects and strengthens the tooth structure, giving the tooth a longer life than it would have if restored by fillings or other types of restorations.
There are three common types of crowns: all-porcelain (tooth colored), porcelain fused to metal, and gold.
A tooth colored crown. Crowns made of zirconia are durable and resist cracking. They are more opaque looking and best for back teeth and people who clench and grind their teeth where durability is important. There are other A very aesthetically pleasing crowns made of other ceramics recommended for front teeth.
Porcelain Fused to Metal
A metal based crown with porcelain baked to the outside to make it more aesthetically appealing. This type of crown is great for someone who wants a tooth colored crown but still wants durability. There is still a risk of fracturing these types of crowns but usually it is just the outside porcelain that chips off.
This type of crown is very durable! They are recommended for back teeth where the crown cannot be seen, and they are often recommended for people who grind or clinch their teeth. Gold crowns are most like your natural teeth and your tissue adapts best to this material. Also, less actual tooth structure needs to be removed for this type of crown.
If a crown is needed, Dr. Wentworth will discuss what type of crown would be best for you.
Reasons for Crowns
What Does Getting a Crown Involve?
A crown procedure usually requires two appointments. During your first appointment, the dentist will prepare the tooth by removing any decay and shaping the surface to properly fit the crown. Then he or she will take impressions that will be sent to the lab to create your custom crown. You will wear a temporary crown for approximately two weeks while your custom crown is being fabricated.
At your second appointment your temporary crown will be removed, the tooth will be cleaned, and your new crown will be carefully placed to ensure the spacing and bite are accurate.
You will be given care instructions and encouraged to have regular dental visits to check your crown. As always, proper oral hygiene will help extend the life of your new crown.
