Health One or more missing teeth can have a significant effect on the appearance and functionality of your smile. Many people who are missing teeth are too self-conscious to smile. Additionally, tooth loss can lead to a variety of dental health problems including changes in your bite, shifting of your teeth, TMJ Disorder, speech impediments, an increased risk of periodontal disease and a greater chance for developing tooth decay. When a tooth is severely damaged or missing, dental restorations are necessary to preserve your dental health. A dental crown is designed to save an existing tooth, while a dental bridge replaces missing teeth. Not only do these restorations improve your dental health, but also dental crowns and bridges closely resemble your natural teeth. Both crowns and most bridges are fixed prosthetic devices. The Low-down on Dental Crowns When a tooth is heavily decayed, it is more likely to fracture and lose considerable tooth substance. The greater risk is that a fracture line may go below the margin of the gum, which makes restoration more difficult, or near impossible. Dental crowns are synthetic caps, usually made of tooth-colored porcelain, placed on the top of a tooth to improve function and appearance. Crowns can also be used to attach bridges, cover implants, prevent a cracked tooth from becoming worse, or to restore an existing filling is in jeopardy of becoming loose or dislocated. In addition, crowns can serve an aesthetic use, and are applied when a discolored or stained tooth needs to be restored to its natural appearance. A tooth must be resized to accommodate a crown. A cast is made of the existing tooth and an impression is created, which is sent to a special lab that manufactures a custom-designed crown. In some cases, a temporary crown may be applied until the permanent crown is ready. With proper care, a good quality crown can last up to eight years or longer. It is very important to floss in the area of the crown to avoid excess plaque or collection of debris around the restoration. Behaviors such as jaw clenching or bruxism can significantly shorten the life of your crown, in addition to eating brittle foods, ice or hard candy. Close the Gap with Dental Bridges Dental bridges are natural-looking dental appliances that can replace a section of missing teeth. Since they are custom made, bridges are barely noticeable and can restore the natural contour of your teeth as well as the proper bite relationship between upper and lower teeth. A bridge may be recommended if you are missing one or more teeth. Gaps left behind by missing teeth will eventually cause the remaining teeth to rotate or shift into the empty spaces, resulting in a bad bite. The imbalance that is caused by missing teeth can also lead to gum disease and temporomandibular joint (TMJ) disorders. If you have damaged or missing teeth, it is recommended that you visit your Port St. Lucie dentist for further consultation on the best procedure for restoration. Dental crowns and bridges are not for everyone, but making a visit to your dentist the first step to fully restoring your smile. About the Author: 相关的主题文章:
