Tooth reshaping is a cosmetic procedure that deals with subtle changes to the teeth, including correcting imperfections or problems like slight overlapping, irregularly shaped teeth and small chips.
Tooth adjusting or dental contouring, is a cosmetic dentistry technique that removes small amounts of tooth enamel in order to change the shape, length, or surface of one or more teeth. Even a millimetre of reduction in the right places can really improve the appearance of your smile. Tooth adjusting is performed using polishing instruments and abrasion techniques. A sanding instrument is used to artfully adjust imperfections on the surface of the teeth, and sandpaper-like strips may be used to contour the sides of the teeth, before the they are smoothed and polished.
Bonding is the application of a tooth-coloured composite resin (plastic) to repair a decayed, chipped, fractured or discoloured tooth. Unlike veneers, which are made in a laboratory, bonding can be done in a single visit. Bonding is often used to correct minor imperfections such as closing small spaces between the teeth, making the teeth look longer or changing the shape or colour of teeth.
The procedure is simple and usually requires very little or no reduction to the natural tooth structure. First, the dentist will select a composite resin shade to match the colour of the surrounding teeth, then etch the tooth to roughen the surface. Once the tooth is ready, the dentist will apply the resin and mould and smooth it until the desired shape is reached. From here, the resin is hardened with a special light. The dentist will then further trim and shape the tooth, polishing the surface to match the rest of your teeth.
Success of dental bonding is determined, in part, on the location of the restoration on the tooth. If the bonding is on the very edge of your tooth, it most likely won’t last as long because of biting forces and the types of food you are biting into. Chewy, hard or crunchy foods will weaken the bonding quickly or cause fractures. Composite veneers will also tend to stain over time and the rate at which this will happen will depend upon your dietary and oral hygiene habits. Bonding can last 4 to 8 years on average, depending on your bite, diet and oral hygiene habits
Porcelain veneers can be thought of as shells bonded to the smiling surface of the teeth. This is similar to dental bonding, however is made in the lab due to the firing needed of the ceramic.
Porcelain is significantly stronger and more aesthetic than plastic fillings. This means that they are often considered as more of a long term option. Additionally, they also provide increased strength to the teeth they are bonded to for a longer lasting smile.
