Teeth Bonding in Winchester VA

Purpose of Teeth Bonding

Teeth bonding is a process which a dental filling, crown, or restoration is attached to the tooth, in order to be retained in place and not become dislodged while you are eating, chewing, etc. This process involves special techniques and materials, designed to enhance the bond to the tooth structure.

Types of Teeth Bonds

There are generally three main categories when it comes to bonding, depending on the method which the filling or crown is attached to the tooth:

  1. Mechanical bonding: Where the design of the tooth is altered, by creating a special locking mechanism in the tooth, with which the restoration interlocks, and it’s movement is prevented. Example of that is creating a groove in the tooth, into a small projection that the crown fits, creating a sort of key and lock mechanism and holding the crown in place.
 A Variation of this technique is called Micro-Mechanical bonding, where a special acid is used to create a roughness of the tooth surface, then a fluid called bonding agent is applied to the tooth, creating a bridge between the tooth and the filling material. This occurs with tooth-colored fillings (also known as dental composite).
  2. Chemical Bonding: Where the filling binds chemically to the tooth structure. The chemical bond is created through exchange of minerals like calcium and phosphate between the tooth and the filling material. This occurs with fillings such as glass ionomer and Zinc Polycarboxylate fillings.
  3. Chemico-Mechanical Bonding: is generally a mixture of the two techniques, where the tooth structure is altered to create the interlocking area, and the material itself binds chemically to the tooth structure. This technique is used mainly when the destruction is severe, requiring an extra method for keeping the filling in place.

Prior Bonding Failure

If a filling or crown detaches from the tooth, did the bonding fail? In most cases that is correct. If a crown or filling is detached from the tooth, it means that the bonding mechanism failed, and in this case Dr. Haynie will either attempt to identify the problem and fix it, or change the technique of bonding. However, if a restoration fails, it is not always due to failure of bonding. There are times when part of the restoration or the tooth breaks off and that specific restoration had failed. In some cases a patient may eat prohibited food that is hard and causing the filling or crown to move.

Selecting the Best Technique

At our Winchester dental office, Dr. Haynie can help you in the choice of which type of bonding technique to use, this may also depend on the case presented. For example, if the cavity or decay is minimal, there is sufficient tooth structure to create the locking mechanisms for the mechanical type, but if the tooth is severely destructed, creating these locking mechanisms can cause complications, such as exposure of the pulp (or nerve) or fracture of the tooth, and therefore the chemical type is preferred.
