What are dental crowns?
Over time, your teeth have probably degraded. There are plenty of reasons to damage your teeth, such as cavities, injuries, etc. Gradually, your teeth can lose their shape and function.
Dental or porcelain crowns are considered a coat that covers the visible portion of the tooth. The shape of any crown is created based on its natural tooth. Unlike metal-based crowns, the advantage of porcelain crowns is an aesthetic factor as the replacement looks like the former, which is important if you get the crown for your front teeth.
Who needs a crown ?
The patients who need a dental crown are those that have:
- A tooth is severely decayed or damaged: If a tooth has a large cavity or has been weakened by a fracture or other trauma, a crown may be needed to restore the tooth’s strength and function.
- A tooth has undergone a root canal: After a root canal, a tooth may become weakened and more susceptible to fractures. A dental crown can protect the tooth and help prevent future damage.
- A tooth is severely discolored or misshapen: A dental crown can be used to cover a tooth that is severely stained or discolored, or to improve the appearance of a tooth that is misshapen or otherwise aesthetically unappealing.
- A tooth is used to anchor a dental bridge: Dental bridges are used to replace missing teeth. The teeth on either side of the gap are typically fitted with dental crowns to anchor the bridge in place.
- A dental implant is being placed: Dental implants are used to replace missing teeth. A dental crown is typically placed on top of the implant to restore the appearance and function of the missing tooth.
Your dentist can evaluate your specific dental needs and recommend a dental crown if it is the best course of treatment for your particular situation.
Why are dental crowns needed?
You may want to consider a porcelain crown if you:
- Have recently suffered an injury to your tooth, to protect a weak tooth from fracture or restore a cracked, worn down tooth.
- Require an anchor for a dental bridge, to hold the dental bridge in place.
- Want to reshape a crooked tooth, to enhance your smile.
- To replace a large filling that has come loose or fallen out, to cover and support the teeth with filling.
- Have been treated with a root canal treatment.
Essentially, the role of porcelain crowns is to protect the tooth and improve the strength and durability of an existing tooth.
What is the process of porcelain crown treatment?
Porcelain crown treatment usually necessitates 2 appointments. Because your tooth is prepared for the placement of the porcelain crown. On the first visit, the dentist will take X-rays of the tooth and the bone around it. You may need to have a root canal treatment if there’s any:
- Tooth decay.
- Risk of infection.
- Injury to the tooth’s pulp.
The dentist will then identify, remove fragile parts of the tooth, and make more room for a temporary crown. And if your tooth loses too much, a filling can be used to expanse your tooth before the crown covers.
After the natural tooth is ready, a paste or putty is used to make a copy of the tooth. The copies will also be made for the teeth above and below the tooth that’s getting the dental crown. The involved impressions are to ensure that the crown will not interfere with your eating.
The impressions will reach a laboratory. The laboratory will make the crowns, and this process usually takes 2 to 3 weeks. Before the next visit, your prepared tooth will be restored with a temporary crown while you’re waiting for the permanent one.
The second visit is usually in the next 2 weeks, your temporary crown will be removed and the permanent one will be checked. If everything is okay, the gum below your tooth will be numbed and the new crown will be fitted.
Dental crown treatment in one day. Dental crowns can also be made in a dental office if your dentist has the necessary equipment. This process is conducted similarly to the traditional way — this procedure begins with the removal of decay and shaping of the tooth to ensure an entire fit inside the crown.
Because the permanent crowns are made in a day, the next stage is different from the traditional way. A scanning device (a “wand”) is used to take digital pictures of the tooth inside your mouth. These images are assessed by the computer’s software that builds a 3D model of the tooth. Then the digital design is delivered to a second in-office machine to cut a ceramic block into the shape of the crown. This method is called computer-aided or computer-aided manufacturing (CAD/CAM). In about 15 minutes, the crown is done to be cemented into place.
What are dental crowns made of?
Permanent crowns can be made out of many different materials. These materials can include:
- Metal: Dental crowns can be made from a variety of metals, including gold, palladium, nickel, and chromium. Metal crowns are the least likely to chip or shatter, wear down the least quickly, and only need a little portion of your tooth to be removed. The metallic color is the main drawback of this type of crown. The biggest disadvantage of this kind of crown is its metal crowns. Metal crowns are a good option for hidden molars.
- Porcelain-fused-to-metal: This kind of dental crown can be fit to the color of the natural teeth that’s next to the crown. They have a natural look. However, occasionally a black line can be seen as the metal underneath the porcelain crown top. Other drawbacks include the potential for the porcelain piece of the crown to shatter or break off and the crown wearing down the teeth next to it in the mouth. Dental crowns made of porcelain bonded to metal may be a considerable option for front or back teeth.
- All-resin: Resin-based dental crowns are often less costly than other crown types. They are more prone to crack than porcelain-fused-to-metal crowns, although they wear down over time.
- All-ceramic or all-porcelain: Compared to other crown types, these kinds of dental crowns offer the closest approximation to natural skin tone. They’re also a wise choice if you’re allergic to metal. They lack the strength of porcelain-fused-to-metal crowns. Additionally, unlike metal or resin crowns, they have the potential to damage the teeth next to them. Front teeth suit for all-ceramic crowns.
- Pressed ceramic: There is a firm inner core in these dental crowns. Pressed ceramic dental crowns replace the metal liner that’s used in the all-ceramic crown-making process. Porcelain is used to cap pressed ceramic crowns because it offers the closest natural color match. They are more long-lasting than an all-porcelain crown…
Comparison: Metal vs porcelain crowns
Metal crowns are typically made from cobalt-chromium, nickel-chromium and other metal-based alloys. Metal crowns are well-known for their durability and have been used in dentistry for a lot of years. Compared to porcelain crowns, they are the least prone to wear down over time or get chipped or broken. The majority of patients decide to have metal crowns placed on their back teeth (posterior teeth) since they are hidden.
On contract, porcelain crowns are made to resemble the natural appearance of your teeth and come in 2 main forms: all-porcelain or all-ceramic. Both are safe options for people with metal allergies and can be utilized for both front and back teeth.
What are onlays and 3/4 crowns?
You can utilize a variety of crown kinds on your teeth. Dental crowns such as onlays and 3/4 crowns don’t completely cover your teeth as standard dental crowns do. A standard crown will cover your entire tooth. When you still have a healthy tooth structure, onlays and 3/4 crowns could be appropriate. When opposed to full covering of your crown, it is seen to be a more conservative technique. Your dentist does a reshaping of the tooth to prepare it for the crown during this process.
Should I get an implant or a crown?
This is dependent on your tooth health and the recommendation of your dentist. A dental implant is an artificial or prosthetic root that serves the same purpose as a natural tooth root. The implant is inserted into your bone, where the root would be, and used with your jawbone to provide a long-lasting and stable fit. Your implant essentially serves as the base for your dental crown. They work together to mimic the structure and appearance of a natural tooth. While a crown can replace part of a broken tooth, it can’t fully restore a tooth without the use of an implant.
