Do you have a chip or a fracture on your teeth? Dental bonding is the most cost-efficient manner of treating these kinds of dental imperfections. This procedure involves the use of composite resin material on the tooth, and then molding this material in order to improve the appearance of the tooth in question. But the question now is this — what is the science behind the dental bonding procedure?
Principle No. 1: Your dentist makes use of an acid agent in order to treat the dental enamel.
Your dental enamel is a very mineralized tissue which means that it resembles bone. Naturally, the enamel layer is a very tough material. The problem is that the composite resin material cannot adhere to the enamel layer of your teeth if it the surface is smooth. Hence, your dentist will have to etch the dental enamel layer with the use of an acidic enamel conditioner. Basically, what it “etching” means is to roughen the surface of the tooth to give a frosted appearance. Think about etching as the same manner wherein glass is etched in order to render color to the material.
Principle No. 2: Your dentist requires a bonding agent.
When the tooth has been etched, your dentist will then apply a liquid plastic substance which is more commonly known as the bonding agent for the composite resin material. The liquid material will be capable of seeping into the microscopic ridges and grooves which are found on the surface of the tooth. Once the dentist has applied a layer of the bonding agent on the surface of the tooth, a curing light is applied on the tooth so that the material can become locked with with the enamel tissues.
Principle No. 3: The composite resin material provides the needed bulk.
Basically, the bonding part of the dental bonding procedure has already been completed with the adhesion of the bonding agent with the enamel of the tooth. However, this isn’t enough to substantially change the appearance of your tooth. For this reason, your dentist would have to make use of composite resin material in order to add thickness to the tooth and change the appearance of the tooth. Just like with the bonding material, the composite resin has to be exposed to the curing light in order to ensure that the composite material bonds well with the rest of the tooth, increasing the resin’s durability and strength.
