Dental Crowns In Glyfada
A dental crown is a tooth-shaped case that is placed over a tooth - to restore shape and size and improve its appearance. Crowns, when bonded in place, completely enclose the entire visible portion of a tooth that is above the gum line.
Why do you need them?
A crown may be needed in the following cases:
- Για να προστατέψετε ένα αδύναμο δόντι (για παράδειγμα, από τη φθορά) από το σπάσιμο ή από το ράγισμα
- To restore an already broken tooth or a tooth that has been severely damaged
- To cover and support a tooth with a large filling when there is not much tooth
- To hold a dental bridge in place
- To cover deformed or discolored teeth
- To cover a dental implant
- To make an aesthetic modification
Types of dental crowns
- Permanent crowns can be made of stainless steel, gold or other metal alloy, porcelain fused with metal, or ceramic material.
- Stainless steel crowns are prefabricated crowns that are used on permanent teeth mainly as a temporary measure. The crown protects the tooth or the filling while the permanent crown will be made of another material.
- The metals used in the crowns include alloys high in gold or platinum or alloys of base metals (for example cobalt-chromium and nickel-chromium alloys). Metal hoops are resistant to biting and chewing forces and are likely to withstand wear as much as possible. Also, metal hoops rarely crack or break. The metallic color - and the high price of gold - is the main disadvantage.
- Porcelain crowns can be combined with your own natural teeth. However, with this type of crown, more damage occurs to the opposing teeth compared to metal crowns. The porcelain section may also crack or break. Porcelain and metal crowns look more like normal teeth. However, sometimes the metal under the porcelain of the rim can appear as a dark line, especially on the gum line and even more so if your gums recede. Crowns can be a good choice for front or back teeth as well as large bridges where metal is essential for durability.
- All-ceramic crowns provide better natural color matching than any other type of rim and may be more suitable for people with metal allergies. Ceramic crowns can be used for front and rear teeth.
- Temporary versus permanent. Temporary crowns can be made at your dentist's office, while most permanent crowns are usually made in the dental laboratory. Temporary crowns are usually made of acrylic material and can be used as a temporary restoration until the permanent crown is made by the laboratory.
Before and After
What is the Process?
Preparing a tooth for a dental crown usually requires two visits to the dentist - the first step involves examining and preparing the tooth, the second visit involves placing the permanent crown.
First Visit
- At the first visit to prepare a crown, your dentist may take a few x-rays to check the roots of the tooth receiving the crown and the surrounding bones. If the tooth has extensive caries or if there is a risk of infection or injury to the tooth pulp, endodontic treatment can be done first.
- Before the crown procedure begins, your dentist will anesthetize the tooth and the gums around the tooth. The crown-receiving tooth is then prepared along the chewing surface and the ribs to make room for the crown. The amount removed depends on the type of hoop used. If, on the other hand, a large area of the tooth is missing (due to caries or damage), the dentist will use filling material to build the tooth to support the crown.
- After preparing the tooth, your dentist will usually use a material to make the tooth imprint to receive the crown. Tooth prints above and below the tooth to receive the dental crown will also be made to make sure the crown will not affect your bite.
- The impressions are sent to a dental laboratory where the tooth case - crown will be made. The crown is usually returned to your dentist within two to three weeks. If the crown is made of porcelain, your dentist will also choose the color that best matches the color of the neighboring teeth. During this first visit, your dentist will make a temporary crown to cover and protect the prepared tooth while the crown is being made. Temporary hoops are usually made of acrylic and held in place using temporary glue.
Second Visit
During the second visit, your dentist will remove the temporary crown and check the fit and color of the permanent crown. Local anesthetic will be used and the new crown will be glued with permanent glue.
How to take care of them?
Because temporary crowns are a temporary solution until the tooth case is ready - most dentists recommend the following:
- Avoid sticky foods (for example, chewing gum, candies), which have the ability to peel off and pull the rim.
- Do not use the side of your mouth with the temporary rim. Move most of the chewing to the other side of the mouth.
- Avoid chewing hard foods (such as raw vegetables), which could break or break the temporary.
- Pull instead of flossing when brushing between your teeth to avoid pulling on the temporary crown.
Possible Issues
Sensitivity
Your tooth may become sensitive immediately after the procedure as the anesthesia begins to decrease. If the crowned tooth still has a living nerve, you may be sensitive to the cold or the hot. Your dentist may recommend brushing your teeth with toothpaste specifically for sensitive teeth. The pain or tenderness that occurs when you usually bite means that the crown is too high on the tooth. If this happens, call your dentist.
Cracked Crowns
Crowns can sometimes crack. If the crack is small, a composite resin can be used to repair it with the rim remaining in your mouth. This is usually a temporary solution. If the crack is extensive, the rim may need to be replaced.
Loose Crowns
Sometimes the glue dissolves from under the rim. Not only does this allow the crown to loosen, it allows bacteria to seep in and cause decay in the remaining tooth. If you feel a crown is loose, contact your dentist.
Detached Crown
Sometimes the crowns come off. Reasons include the caries of the underlying tooth and the dissolution of the glue used to place the crown. If your crown comes off, contact your dentist immediately. He will give you specific instructions on how to take care of your tooth and crown until he sees you. Your dentist may be able to put the crown back in place. If not, a new hoop will need to be made.
Allergic Reaction
Because the metals used to make the crowns are usually a mixture of metals, an allergic reaction to the metals or porcelain used in the crowns may occur, but this is extremely rare.
Dark line on the tooth next to the gum line
A dark line next to the gum line of the tooth with the crown is normal, especially if you have a porcelain crown - fused with metal. This dark line is simply the metal of the hoop pointing inward. Although not a problem in itself, the dark line is aesthetically unacceptable and your dentist may need to replace the crown with another.
How long do they last?
On average, dental crowns last between 5 and 15 years. The lifespan of a crown depends on the amount of wear exposed, how well you follow your oral hygiene instructions and personal habits related to your mouth (you should avoid habits such as grinding or clenching your teeth, chewing ice, biting your fingers , or use your teeth to open packages or bottles).
Does a tooth with a crown require special care?
While a crowned tooth does not require special care, remember that just because a tooth is crowned does not mean that the tooth is protected from wear or gingivitis. Therefore, continue to have good oral hygiene habits, including brushing your teeth at least twice a day and flossing daily - and rinsing with antibacterial mouthwash at least once a day.
