This is why a cosmetic dentistry procedure can involve a lot of extraction especially if you teeth are too many and the space inside the mouth is too cramped for all your teeth. It can also involve braces and elastic bands and sometimes, replacing the whole teeth with a fake one that is inserted into the gums. Some are downright good and natural-looking you cannot tell the difference. Today s technology has made it so that there are now individual ways to fix, repair, mend and restore teeth, with each one tailor-fitted to the damage. Crowns and tooth cracks Dental crowns are the latest ways of fixing teeth cracks. An example would be the case of simple dental fillings. In the old days, dental fillings are made of gold, amalgam and other materials that leave dark spots on the teeth. Today, you may choose the color of your dental fillings made of porcelain or composite materials that match the color of your natural teeth. Depending on the extent of the treatment, there might be a need for anesthetic injections. Next, the dentist roughens the existing tooth for the resin to adhere properly. He will then apply a gentle phosphoric acid solution on the tooth s surface (which does not hurt) and removes it after 15 seconds. 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. Onlays help conserve more tooth structure because they require minimal removal of tooth surface during the bonding process. Benefits The biggest benefit for both inlays and onlays is avoiding the need for more extensive treatments using expensive dental crowns, dental bridges or dental implants. Unlike old metal fillings, inlays and onlays do not expand or contract in contact with hot or cold foods.
