If you have a damaged tooth, bonding could be a good solution to restore it. At our office, we can use dental bonding to repair decayed, chipped, fractured, or discoloured teeth. Unlike veneers, which are custom-made in a dental laboratory, bonding can be completed in one dental visit.
Dental bonding is one of the easiest and most economical cosmetic dental procedures. It utilizes a composite resin that is shaped and polished to match the surrounding teeth. Often, bonding is used for cosmetic purposes, such as to improve the appearance of a discoloured or chipped tooth. It can also be used to change the shape or size of the teeth, closing spaces between teeth or making them appear longer. It can also be used as a cosmetic alternative to amalgam (metal) fillings, or to protect a portion of an exposed tooth root that has resulted from gum recession.
Bonding does not require any special preparation or anesthesia (unless the bonding is being used to fill a decayed tooth). Your dentist will first choose the composite resin colour that matches the colour of your tooth most closely. He or she will then slightly etch the surface of the tooth to roughen it; this helps the bonding material to adhere better to the tooth surface. A conditioning liquid will be used to coat the tooth lightly. This further helps the bonding material to adhere. The bonding is applied as a tooth-coloured, putty-like resin. It will be molded and smoothed until it is the desired shape and size, then hardened with an ultraviolet light or laser. Once it has been hardened, your dentist will trim and shape it, then polish it until the bond matches the look of the neighbouring teeth. The entire procedure takes about 30 minutes to an hour to complete (for one tooth; additional teeth may require separate appointments).
It should be noted that, once you’ve completed your bonding procedure, it’s recommended that you avoid tea, coffee, cigarette smoke, and other substances that can stain the resin. Additionally, because the composite resin is not as strong as natural teeth, you should be careful not to bite your nails or chew on pen caps or pens. Bonding may need to be replaced eventually.
