Tooth bonding

Tooth bonding is a single visit procedure and it is reffered to the application of a tooth-coloured resin material using adhesives and a high intensity curing light. Tooth bonding is one of the most simple procedures of the cosmetic dentistry and it is used as a treatment method in various clinical conditions.

Those wishing to have a beautiful and bright smile as well as healthy teeth need to be informed and have the slightest idea about what the tooth restoration means.

There are several clinical conditions that dental bonding is considered to fix. They refer to the following dental issues:

  • To repair decayed teeth (composite resins are used to fill cavities);

  • To repair chipped or cracked teeth;

  • To improve the appearance of discolored teeth;

  • To close spaces between teeth;

  • To make teeth look longer;

  • To change the shape of teeth;

  • As a cosmetic alternative to amalgam fillings;

  • To protect a portion of the tooth’s root that has been exposed when gums recede.

Advantages and disadvantages of dental bonding

Unless multiple teeth are involved, it can be done in a single visit. Compared to veneers, crowns and metal fillings it does not require a lot of tooth enamel removal. When talking about the repairing of decayed teeth, the removal of enamel or dentin depends on the destruction level of the tooth. The procedures that include dental bonding, in most cases do not require anesthesia. Composite bonding is more aesthetical compared to metal fillings. It is much less likely to produce additional cracking than a metal filling. It provides a natural and a healthy look.

Because the bonding material is not as strong as your real teeth it can not last forever. There are vicious habits, such as: chewing on pens, biting on fingernails, bruxism (teeth grinding), etc. that might chip the material. In such cases bonding needs to be repaired. It is also not as strong as other restorative procedures, such as the construction of crowns or veneers. The composite resin material is porous and therefore excessive coffee, tea, and cola consumption, as well as smoking cigarettes will usually discolor the composite.

The bonding technique

The doctor will use a shade guide in order to select the composite resin color that best matches the natural tooth color. Once the color is chosen, the doctor will apply a mild etching solution to the tooth in order to create microscopic gaps in the enamel or dentin structure. These gaps create a rough surface that allows a better bonding of the composite resin. Afterwards, the tooth will be coated with a conditioning liquid which will also help the material to adhere to the tooth. The resin is then applied, sculpted to fit the tooth, hardened with an ultraviolet light or laser and last but not least important it is polished. The procedure usually lasts between 1 and 2 hours.
