Dental fillings became a standard for treating carious lesions or chipped teeth. Types of dental fillings differ in their composition, structure, hardening speed, and, of course, strength. But rarely do people think about what material these products are made of and what types of fillings exist today. Dr.Regina at Cedar Park Dental Wellness will help you choose the most suitable filling, which will last a long time, and it will entirely imitate your dental tissue.
Replacement of amalgam fillings.
Today metal fillings made of amalgam are no longer in fashion. More and more dentists refuse to place them for many good reasons, such as low aesthetics, poor adhesion, discoloration of the tooth, the complexity of installation, metal taste in the mouth, the high toxicity of mercury, high thermal conductivity, and so on. The most commonly used amalgam is a silver amalgam that consists of mercury, silver, tin, zinc, etc.
Why tooth-colored composite fillings?
Cracks or caries are common causes of toothache. An amalgam filling is essentially a piece of silver that closes a cavity in a tooth. Because of the physical properties, such a filling begins to act like a wedge when biting onto the tooth. Therefore, if the amalgam filling is large enough, there is a high risk of breaking the tooth wall.
The adhesion of the amalgam fillings to the cavity walls is exclusively mechanical, while modern composite fillings have another type of bonding - chemical adhesion. The risk of loss of a composite filling is practically zero.
The chewing force, which is transmitted to the hard tissue when biting, spreads more evenly over the tooth with a composite filling, minimizing the risk of cracks or chips.
Composite fillings imitate the natural color of the teeth entirely; therefore, they are more aesthetic.
