The visible part of a tooth, otherwise known as the crown, is only a small portion of the living system. The crown is made up of enamel, the hardest substance found within the body. It is bone that has been enriched with large percentages of calcium. That's why people who drink lots of milk or take calcium supplements have strong bones and teeth. The enamel is thickest at the crown, and thinnest near the roots of the teeth. Throughout your life you end up having 2 completely different sets of teeth. The initial set is the baby teeth (deciduous teeth) that eventually fall out. They are whiter, softer, and less sturdy than adult teeth. Hence, they tend to wear out much faster than permanent teeth, but they also fall out to make room for them. Making sure that there's enough space in the vacancy caused by a lost baby tooth is important for healthy adult teeth. New developments include the implantation of artificial teeth or binding posts into the gums or jawbone; antibiotic fiber for periodontal disease; root canal surgery, a procedure that ameliorates pain while permitting teeth to remain in place; and nearly painless lasers to repair dental cavities, usually making local anesthesia unnecessary.
Dental implants are fixtures of titanium which are surgically screwed into your jaw bone. The implant is an anchor for a naturally-appearing false tooth or a set of false teeth. The success rate of dental implants depends on where the implants are placed and their purpose. They are typically best placed in the front portion of your lower jaw. If you're missing one tooth or all of your teeth, implants may well be for you. So long as you have enough bone in the area of the missing tooth to facilitate the anchorage of the implants, this procedure can yield terrific results. If you don't have enough bone for this purpose, a bone graft may be necessary. If you have a small dental bridge or partial dentures (removable type), implants will be a welcome alternative. Implants are an alternative to a fixed bridge. The implant will last a lifetime, but the crown on top of it will last ten to fifteen years. If you're missing one tooth or all of your teeth, implants may well be for you. So long as you have enough bone in the area of the missing tooth to facilitate the anchorage of the implants, this procedure can yield terrific results. If you don't have enough bone for this purpose, a bone graft may be necessary. A procedure of building up the bone is known as Bone Grafting. Bone grafting is common with dental implants. The bone that is used is one of three types. The preferred bone to use is taken from other areas of your mouth or collected in a suction device as the drilling of the sites for dental implants occurs. Sometimes bone is taken from areas such as a hip (this requires an orthopedic surgeon and an operating room). The third source for needed bone is a synthetic type. This is the least preferred type of bone to be used for this procedure.
If you have a cavity in a tooth, broken fillings, mercury fillings, or amalgam fillings, this type of dental filling is well worth discussing with your dentist. Mercury fillings or amalgam fillings can easily be removed and replaced with far more attractive colored fillings. These fillings actually strengthen your tooth beyond the level it had with the amalgam fillings. Composite resins may also be used to enhance the appearance of any tooth, which is a tooth bonding procedure. The composite resin will strengthen and enhance the natural tooth structure as it does with use as a dental filling. Your dentist will give you a local anesthetic to numb the area. The dentist then prepares an access to the decayed area of the tooth and removes the decayed portions. This is accomplished with traditional drills, micro air abrasion or even with a dental laser. With a composite filling, your dentist will preserve more of the natural tooth as the composite resin can be bonded to the tooth in thin layers. If your tooth's decayed area is close to a nerve, a special liner will be used to protect the nerve.
Dentures are removable replacements for missing teeth typically made out of an acrylic resin which at times incorporate porcelain or metal for additional structural support. The setting up dentures procedure begins with a wax bite impression of your mouth that will give your dentist exacting measurements. A try-on appointment will fine tunes color, shape, and custom-fit. After your final dentures are fabricated, they will be placed and informed of their required care. The main component of dentures is acrylic resin molded over the top of various combinations and paterns of metal. In oreder to use dentures all of the teeth in the top or bottom or both top and bottom of the mouth are removed. It is recomended that after the removal of the necessary teeth that the patient wait at least a month to have the dentures fit to the mouth. The waiting period allows for proper healing in the mouth to take place.
This section of our cosmetic dentistry information site provides you with some background into dental veneers, both composite veneers and porcelain veneers. Dental veneers, sometimes called tooth veneers, can be used to correct both color and shape problems. There are several corrections that you can make to the color of your teeth as well as the shape of your teeth! Some of the causes of tooth discoloration are staining, aging, chemical damage, disease, medication, and genetics. Dental Veneers (Tooth Veneers) are used to correct both the color and the shape of teeth. While no alternative to veneers will create the exact same effect, there are some popular procedures that may seem worthwhile. Crowns, while more expensive, also act to cover the tooth with a protective coating. For individuals who simply want to brighten their teeth, many clinics now offer tooth bleaching, though this is a much less permanent procedure.
Bonding is a composite resin filling placed in the back teeth as well as the front teeth. Composites are the solution for restoring decayed teeth, making cosmetic improvements and even changing the color of your teeth or the reshaping of teeth. Bonding will lighten any stains you may have, close up minor gaps and can be used to correct crooked teeth. The resin comes in many shades so that we can match it to your natural teeth. Due to the layers involved, this procedure will take slightly longer than traditional silver fillings because multiple layers of the bonding material are applied. Typically bonding takes an hour to two hours depending on your particular case. You are good candidate for tooth bonding, if you have close, small gaps between your front teeth, or if you have chipped or cracked teeth, you may be a candidate for bonding. Bonding is also used for patients who have discolored teeth, uneven teeth, gum recession or tooth decay. Bonding material is porous, so smokers will find that their bonding will yellow. If you think you are a candidate for bonding, discuss it with your dentist.
Tooth reshaping, or tooth sculpting, is a safe and conservative way to improve your smile. Teeth may become weaker if large amounts of enamel are removed, tooth reshaping should be limited to minor changes or combined with veneers or bonding for the best smile. The cosmetic dentist will mark your teeth with a pencil prior to performing the procedure. This helps the cosmetic dentist in their sculpting process. As your cosmetic dentist sculpts the tooth, imperfections are artfully eliminating or minimized. A sanding drill or laser may be used to remove small amounts of surface enamel gradually. Abrasive strips are then moved back and forth between your teeth to shape the actual sides of your teeth. Then the teeth are smoothed and polished. Usually anesthetic is not needed. Teeth contouring and reshaping usually takes one to three visits. Contouring teeth may also help correct small problems with bite. It is common for bonding to be combined with tooth reshaping to achieve a beautiful smile. There are actually several ways to change the appearance of your teeth. Many times these various procedures are combined in different ways to deliver that smile of your dreams.
As we age, many of us find ourselves with teeth that are no longer structurally sound. Root canals, lost fillings, decay below a filling, chipping and cracking of the enamel are all things that can lead to large scale defects in a tooth's surface. When the entire surface of the tooth is a problem, but the root system is intact, a crown might be just what the dentist orders. Grinding your teeth, an improper bite, age, fillings and tooth decay can all be contributing factors in the wearing down, cracking or breakage of your teeth. Dental crowns cover the entire visible surface of your affected tooth and add strength, durability and tooth stability. In other instances, crowns are used to replace a actual missing tooth. These crowns are anchored to the teeth on either side, with a bridge section connecting the two crowns. Instead of bridges, single tooth dental implants may be used that eliminate the need for supporting the crowns. There are basically three types of crowns, those made of gold, ceramic crowns and ceramic-veneered gold crowns. Gold and metal-ceramic crowns are extremely durable and are normally used in molars, where the forces from chewing and grinding are most prevalent. Ceramic crowns are used primarily for front teeth, since they can best resemble the natural tooth color.
Teeth straightening is accomplished with a number of different procedures and is usually done on children and adolescents when their permanent teeth begin growing in. Crooked teeth, crowded teeth, and even overbites and underbites can be treated with various teeth straightening techniques. While considered a cosmetic procedure, some people require teeth straightening in order for their teeth to be aligned in such a way that chewing is possible. Severe overbites and underbites can result in serious consequences over time, and even overly crowded teeth can mean health problems for the mouth. The most common method of teeth straightening remains standard orthodontic braces. Archwires, springs, and rubberbands apply pressure to the individual teeth by means of brackets that are glued onto their surface. Regular visits are required to the orthodontist in order to tighten wires as needed and make other adjustments. At each visit, the wires will be tightened slightly to renew pressure and push them toward their intended position. Additional wires, rubberbands, and headgear may be prescribed to help move the teeth into their ideal position as quickly as possible. When the teeth have all been repositioned, the brackets will be removed and a retainer must be worn to prevent relapse for some period of time.
