why do you get caps on your teeth
A is a -shaped "cap" that is placed over a -- to cover the to restore its shape and size, strength, and improve its appearance. The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line. Why Is a Dental Crown Needed? A To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth
To restore an already To hold a To cover a For children, a crown may be used on primary (baby) teeth in order to: Save a tooth that has been so damaged by decay that it can't support a filling. Protect the teeth of a child at high risk for tooth decay, especially when a child has difficulty keeping up with daily oral hygiene. Decrease the frequency of general anesthesia for children unable because of age, behavior, or medical history to fully cooperate with the requirements of proper. In such cases, a pediatric dentist is likely to recommend a stainless steel crown. What Types of Crowns Are Available? Permanent crowns can be made from stainless steel, all metal (such as gold or another alloy), porcelain-fused-to-metal, all resin, or all ceramic.
Stainless steel crowns are prefabricated crowns that are used on permanent teeth primarily as a temporary measure. The crown protects the tooth or filling while a permanent crown is made from another material. For children, a stainless steel crown is commonly used to fit over a primary tooth that's been prepared to fit it. The crown covers the entire tooth and protects it from further decay. When the primary tooth comes out to make room for the permanent tooth, the crown comes out naturally with it. In general, stainless steel crowns are used for children's teeth because they don't require multiple dental visits to put in place and so are more cost- effective than custom-made crowns and prophylactic needed to protect a tooth without a crown. Metals used in crowns include alloys that have a high content of gold or platinum, or base-metal alloys (for example, cobalt- and nickel-chromium alloys). Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down. Also, metal crowns rarely chip or break. The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight molars.
Porcelain-fused-to-metal dental 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. The crown's porcelain portion can also chip or break off. Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth. However, sometimes the metal underlying the crown's porcelain can show through as a dark line, especially at the gum line and even more so if your gums recede. These crowns can be a good choice for front or back teethPas well as long bridges where the metal is needed for strength. All-resin dental crowns are less expensive than other crown types. However, they wear down over time and are more prone to than porcelain-fused-to-metal crowns. P All-ceramic or all-porcelain dental crowns provide better natural color match than any other crown type and may be more suitable for people with metal. All-ceramic crowns can be used for front and back teeth. Temporary versus permanent. Temporary crowns can be made in your dentist's office, whereas most permanent crowns are made in a dental laboratory.
Typically, temporary crowns are made of an acrylic-based material or stainless steel and can be used as a temporary restoration until a permanent crown is constructed by a lab. Your dentist may recommend that you undergo a dental crown procedure for one of several reasons: you have a particularly weak tooth that needs to be held together or requires a bridge; you have a tooth that is extremely discolored; or you wish to have a crown placed for cosmetic reasons. There are several types of that can be used, including ceramic, porcelain, resin, and stainless steel (cosmetic crowns are usually made of porcelain or ceramic). Since, according to the American Dental Association (ADA), there are pros and cons for each type, you should have your dentist address your specific situation and make a recommendation on which is best for your tooth. The procedure for installing a dental crown normally takes two separate dentist visits. At your first appointment, your dentist will examine the tooth to make sure that it can support a crown, then begin filing it down to prepare for the crown.
Alternatively, if the tooth is, your dentist may need to fill it in to make it large enough to properly receive the crown. According to the Cleveland Clinic, after the tooth is filed or filled to the proper shape, your practitioner will take an impression of the tooth, as well as those surrounding it, and send it away to a dental lab, so the permanent crown can be made accordingly. By the end of this first visit, your tooth will have a new temporary crown that protects it until the final crown is ready to be permanently placed. When the permanent crown is ready, you will have your second visit. At this appointment, the temporary crown is removed, after which the dentist will position and fasten the new crown to the tooth with a special adhesive. Once your dental crown procedure is complete, it may take some getting used to before the permanent crown feels normal in your mouth; however, after a little time has passed, the crown should look, function, and feel like a regular tooth. If you have any questions about your crown after your procedure, be sure to talk to your dentist.
