A dental crown is a cap-shaped restoration that covers the entire surface of the tooth. It can protect a damaged tooth, increase the lifetime and durability of a decayed tooth, or restore the strength of an otherwise weakened tooth. Crowns are custom-made to be highly lifelike and can also improve the aesthetics of a discolored or irregularly shaped tooth.
When Would I Need A Dental Crown?
If you want a smile that’s your crowning glory, you may need a crown to cover a tooth to help restore it to its normal shape and size. A crown can make your tooth stronger and improve its appearance.
A crown can help strengthen a tooth with a large filling when there isn’t enough tooth remaining to hold the filling. Crowns can also be used to attach bridges, protect a weak tooth from breaking or restore one that’s already broken. A crown is a good way to cover teeth that are discolored or badly shaped. It’s also used to cover a dental implant.
If dental crown provider in Santa Rosa recommends a crown, it is probably to correct one of these conditions. Your dentist’s primary concern, like yours, is helping you keep your teeth healthy and your smile bright. Here are some of the most common indications:
Advanced Tooth Destruction
Crowns are often needed when a large cavity threatens the ongoing health of a tooth. A badly broken or decayed tooth needs to be strengthened with a crown because this cannot be done with a filling alone. The crown will keep the cracked tooth together and protect it; thus, it prevents or delays having to have the tooth extracted.
Tooth Shows Large Fillings That Need Replacement
Many times, after removing large old fillings, a crown is indicated to strengthen the tooth and make it aesthetically more pleasing.
The tooth is broken and can no longer be restored with fillings. The tooth may crack or fracture due to a dental trauma or because of the progression of a dental decay that destroys the dental tissues.
In such situations, a post and core is often indicated to replace the missing tooth structure and to support the crown. After the post and core is cemented in place, a dental crown will be manufactured to cover the post and core.
Improving Tooth Aesthetics
Dental crowns may be designed to improve the appearance of a tooth. For example, the tooth shows large, unsightly fillings, discolorations or the tooth is stained or unusually shaped. Many patients simply want to have their smile aesthetically improved.
Endodontically Treated Teeth
It is well known that endodontically treated teeth are often missing significant solid tooth structure and become less resistant. Sometimes they may also change color.
A crown may improve both the aesthetic and resistance of an endodontically treated tooth. In fact, there are many practitioners who argue that all endodontically treated teeth should be protected with crowns.
To Cover Dental Implants
Dental implants are placed into the jawbone to replace one or more missing teeth. Once placed and properly integrated into the bone, implants may then be fitted with a number of different prostheses: dental crowns, bridges or removable dentures.
Retainer Crowns For Dental Bridges Or Dentures
A bridge is a fixed dental restoration used to replace a missing tooth (or several teeth) by permanently joining an artificial tooth to adjacent teeth or dental implants. In this case, the adjacent teeth are covered with dental crowns.
In this situation, dental crowns are utilized to attach bridges and hold them in place. Dental crowns can also be used to attach removable partial dentures or overdentures.
Depending on the location of your affected tooth, your personal preferences, and your budget, dental crown provider in Santa Rosa can fabricate a variety of dental crowns, including:
Porcelain-fused-to-metal crowns –can be color matched to your adjacent teeth (unlike the metallic crowns). However, more wearing to the opposing teeth occurs with this crown type compared with metal or resin crowns. These crowns can be a good choice for front or back teeth as well as long bridges where the metal is needed for strength. This crown provides a stronger bond than regular porcelain because it is connected to a metal structure. It’s also extremely durable.
Advantages of having a PFMCrown
- Aesthetic Appeal – PFM crowns provide you with a beautiful natural smile. Except the dark line which can be seen between the crown and the tooth, they look very similar to all-porcelain crowns.
- Durability – Cosmetic imperfection of PFM crowns is compensated by their strength and durability achieved due to a metal component. Indeed, PFM crowns have a high level of success and with proper brushing and flossing, they can last for many years.
- Better Fit – A metal structure provides a better fit than all-porcelain crowns.
- Reasonable Price – Usually, PFM crowns are cheaper than all-porcelain ones.
All Ceramic Crown
All-ceramic or all-porcelain crowns – provide better natural color match than any other crown type and may be more suitable for people with metal allergies. All-ceramic crowns are a good choice for front teeth.
Advantages of having an All Ceramic Crown
- Durability– Zirconia crowns are extraordinary strong and can withstand most chewing and biting activities. They are very resistible to high temperatures and, as a rule, don’t cause teeth hypersensitivity. Due to the fact that they are made of crystal, zirconium crowns are much stronger than porcelain and porcelain-fused-to-metal ones.
- Appearance – It is hard to differentiate a zirconia crown amongst natural teeth. In addition, zirconia crowns can be modified, according to the shape and size of teeth it will be placed alongside with.
- Non-allergic – Due to their biocompatible structure, zirconia crowns rarely provoke allergic reaction or body rejection.
- Less Tooth Structure Has To Be Removed – It is needed less layer of material to provide a super strength with zirconia crowns. As a consequence, less amount of your original tooth should be removed to fit the crown properly
Dental Crown Procedure
Crowns are completed in two separate appointments – but dental crown provider in Santa Rosa also offer same-day dental crowns. During your first appointment, impressions of your teeth are taken so that the lab can create a crown that matches your original tooth. Next, dental crown provider in Santa Rosa shapes your tooth on the chewing surface and sides to make room for the crown. After this has been completed, he will place a temporary crown over the tooth. The temporary crowns are created in the dentist office, the day of your first appointment. These temporary crowns serve as a temporary restoration until the permanent crown can be made in the dental laboratory. If a temporary crown comes off, come back to re-cement or try a temporary crown adhesive from the store. But, do not use unapproved glues such as super glue.
Permanent Dental Crown
Approximately two weeks after your first appointment, the temporary crown is removed and the permanent is put into place. The permanent crown is specifically custom made for your mouth by the dental lab.
How Long Do Dental Crowns And Last?
With proper care and maintenance, dental crowns can last up to 15 years (or even more).
The most important step you can take to ensure the longevity of your crown is to practice good oral hygiene. Also see your dentist regularly for checkups and professional cleanings and report any discomfort you may notice as soon as possible.
Dental Crown Contraindications
There are only several situations when a simple dental crown has a clear contraindication.
- General conditions that make anesthesia or tooth preparation inadvisable: Some serious conditions may restrain certain dental treatments. These include serious heart diseases, recent strokes, and others. These situations require a medical examination performed by the appropriate specialist.
- When the tooth can be restored with fillings or other restorations: When a tooth can be restored with other types of restorations that do not involve such an extensive preparation (such as composite fillings, inlays, onlays or veneers), it is pointless to prepare the tooth (by grinding) and thus destroy a significant amount of dental tissues.
What Are The Main Drawbacks?
Requires Tooth Preparation
If performed on natural teeth, dental crowns require irreversible tooth preparation (grinding or polishing). This operation leads to the loss of large amounts of healthy tooth tissue and sometimes even endodontic procedures that lead to tooth devitalization.
Dental crowns (especially porcelain or zirconia) entail a much higher cost compared to a filing. Nevertheless, a badly broken or decayed tooth needs to be strengthened with a crown because this cannot be done with a filling alone.
