Facts About Dental Crowns
A dental crown is fairly common and needed to protect a tooth that has been weakened by tooth trauma or tooth decay. They are also routinely recommended for teeth that have undergone root canal therapy. A dental crown can be custom fabricated using dental materials such as porcelain, metal, or a combination of.
The Purpose of A Dental Crown
In order to restore a damaged or fractured tooth, a dental crown can provide strength and durability that will also mimic your natural teeth. They assist in strengthening your tooth following a root canal operation, reinforcing damaged teeth to avoid possible tooth extraction, and maintaining the structure of your teeth. A dental crown will restore form, function, and esthetics of your damaged tooth or teeth.
Different Types of Dental Crowns
Dental crowns are made using high quality dental materials including porcelain, zirconia, metal (such as gold), ceramics, or a combination of materials. The type of material used in a dental crown depends on the following factors:
- Is there gum tissue recession?
- The location of the tooth (front or back).
- The amount of the original healthy tooth structure remaining.
- How much of your teeth will be visible upon smiling.
- The color and size of neighboring teeth.
- The function of the teeth requiring a crown. An incisor will function differently than a molar.
Dental Onlays and 3/4 Crowns
Onlays and 3/4 dental crowns don’t hide much of the underlying tooth as a regular dental crown does. In comparison to complete crown preparation, it is considered a more conservative treatment. In cases where you still have a lot of healthy tooth structure remaining a 3/4 dental crowns or dental onlay may be the proper treatment.
Crown In A Day
Dental technology has advanced where dental crowns can be fabricated on site in a dental office. These crowns are used using CAD/CAM technology. These crowns while convenient are not suitable in many situations and do not give the long term esthetics or function of some of the other crowns listed here.
A temporary crown is made of dental resin. These crowns are made and inserted using a temporary cement. They protect the tooth and smile while a permanent crown is being fabricated.
Porcelain Fused To Metal (PFM) Crown
These crowns have a metal framework underneath and a porcelain facing. The porcelain facing is for cosmetic reasons and can be stained and color matched to your natural teeth. The metal framework can be made of many different types of metals.
All Porcelain Crown
These crowns are the most esthetic of all the crowns available. The entire crown is made up of a durable, cosmetic porcelain.
All ceramic or all porcelain crowns provide the best natural color match than any other dental crown type (also suitable for patients with metal allergies). Porcelain crowns are an excellent choice for front teeth where we want a more cosmetic outcome.
All porcelain crowns are made using your own custom color to match your existing teeth. This allows your final result to be seamless and undetected. Marielaina Perrone DDS use the finest, strongest, and most modern materials available.
All Gold Crown
This type of crown is generally used only in the back of the mouth. They are not a very cosmetic option. However, gold is as close to our natural teeth in terms of strength and the interaction with other teeth.
When is a Crown Needed?
A dental crown may be recommended if you are missing a single tooth or multiple teeth). Crowns are also sometimes necessary after a root canal since the tooth becomes more fragile and requires increased protection.
Dental crowns can also be used for cosmetics. If a tooth has a large dental restoration, a dental crown may be necessary not only for function and strength but also for esthetics.
Cost of Dental Crown in Las Vegas
The financial cost of dental crowns will vary based on the type of treatment necessary and ay additional work needed. Other costs involved in a dental crown procedure could include:
-Post And/Or Build Up. If a tooth has received a root canal already a post will be necessary into one of the canals to give strength to the tooth prior to crown placement. In some cases, a tooth needs to be built up using composite resin to allow for enough tooth structure for fitting and placement of a custom dental crown.
A porcelain crown will generally cost more than a PFM crown. However, dental insurance will generally cover about 50% of the treatment cost (check your benefits to see what is covered and how much).
How Long Will A Dental Crown Last?
Dental crowns on average last a maximum of 15 years with proper care and placement. Longevity factors include:
- Proper Design. A poorly designed dental crown will cause failure at a faster rate as well as possibly cause damage to surrounding teeth.
- Proper Seating Of Dental Crown. Not all dentists have the skill nor experience to ensure a proper seating of your custom dental crown. A poorly trained dentist or poor dental lab can create a crown that does not fit properly. If it does not fit properly and placed in mouth anyway, tooth decay will develop under the crown over time due to poor fit.
- Proper Dental Hygiene Maintenance. This is important to care for your new crown properly. The tooth can still decay along the margins of where the crown meets natural tooth structure.
- Wear And Tear. Dental crowns can wear down over time just like any other material. They are subjected to extreme forces including hot and cold.
Preparation Of Teeth
A tooth is prepared for a crown in a very specific way. Enough tooth structure must be removed to allow for space for your new crown. Once the tooth is prepared, your dentist will take a dental impression using special materials. This impression will also include the bite of the other teeth. This will ensure the new crown fits properly in your smile.
Before you leave the dentist chair a temporary crown will be fabricated. You will return in about 2 weeks for placement of your permanent crown.
Caring For Your New Dental Crown
Your new dental crown should be cared for just like your natural teeth. This should include brushing 2x per day, flossing, and rinsing with an ADA approved mouthwash.
Possible Complications Of Dental Crowns
Complications may include the following:
- Loose Crown – Over time the dental cement can break down causing a loose crown. The crown can also become loose due to the type of foods we eat. For example sticky caramels or candies. The concern is the underlying tooth structure could be damaged. Should see your dentist immediately if you notice your crown is loose.
- Allergic Reactions – While very rare, this can occur. Metal frameworks for crowns can be made up of various metals. And these metals can sometimes cause a reaction.
- Porcelain Chipping – Crowns constructed using porcelain may chip from time to time. Some small chips can occur over time. Sometimes it can be repaired if the chip is small but the success rate is low. Generally when there is a chip in the porcelain a new crown is recommended.
- A dark line close to the gum line – This can occur if the crown was not designed properly. There is a metal collar on a PFM crown. If the crown preparation is not below the gum line or the gum tissue recedes over time, this collar will show thru. It is strictly a cosmetic issue. All porcelain crowns do not have this issue.
- Sensitivity or pain: A freshly crowned tooth may give you distress following the surgery as the anesthetic wears off. You may develop some sensitivity to cold and heat if the capped tooth still has a nerve within it.
