Next, the dentist will then place a bonding compound or a veneer directly on the tooth (or teeth, as the case may be). Afterwards, the dentist may use a drill or laser to sculpt and shape the sides of the new tooth and the existing one. This will become the perfect new bonded tooth that will form part in the shaping of that picture-perfect smile. Studies in the United States show that people who have great sets of teeth and pleasant faces are more trusted by others. They appear to be more honest, warm and more engaging compared to people who do not have great smiles. One reason for this is perhaps on the act of smiling. People who do not have a great set of teeth will feel self-conscious when they smile compared to those who can smile freely and easily. They are also used in restoring any cracked or fractured teeth in case where the damage is not that severe requiring a dental crown restorative procedure. Inlays and onlays today are usually made from porcelain, composite resin and sometimes the good old gold. Like all the other cosmetic dental procedures today, fillings for inlays and onlays can be made from tooth-colored materials and are often used to replace metal fillings. There are also some types of devices that are designed to correct improper TMJ conditions. For instance, a bite guard will have to be worn at night when sleeping to effectively curtail unnecessary grinding of the teeth. In some cases, orthotics has been proven to be effective in gradually treating TMJ disorder. Costs of dental veneers vary sharply depending on the fees of the cosmetic dentist, the skills (technical and artistic) on the ceramist who makes the veneers, and the place where you want your procedure. (Clinics in urban areas charge more.) Porcelain veneers which can last for 10 to 15 years may cost $900 to $2,500 per tooth. Ordinary dentistry just seeks to make sure that we have a set of fully-functioning teeth that we can use to chew our food. It makes sure that we do not have cavities and teeth that are rotting away. It emphasizes good hygiene and nothing else. But with cosmetic dentistry, the emphasis is different. Like cosmetic surgery, the emphasis is on the way we appear to other people.
