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. 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 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. While there is no medical need to whiten teeth, it is a procedure that can have a big impact on a person's self-esteem. Severely yellowed or discolored teeth can make a person self-conscious and reluctant to smile. Some types of tooth discoloration are difficult to whiten and treat. Teeth that have been subjected to trauma may darken significantly, and resist any bleaching procedure. Some medications affect young children when their teeth are first forming and may also be nearly impossible to treat. Dentists will be able to tell what situations may result in bleach-resistant discoloration, and provide advice on how effective various treatments may be. In cases of extreme discoloration that cannot be subjected to common teeth whitening procedures, porcelain veneers applied to the teeth may be an alternative solution. Your cosmetic dentist will make an impression of the tooth and a dental laboratory will create the crown. You will typically leave the office with a temporary crown to wear while the permanent crown is being made - this takes about two weeks. The permanent crown is then cemented onto your tooth. Typically, only two visits are required for this part of the procedure. Often, a preliminary restoration of your tooth may be needed before a crown can be placed. To stabilize your tooth, a filling must first be put in place prior to placing a crown due to the loss of original tooth structure. Tooth crowns usually last ten to fifteen years.
