Fill your teeth with radiation

 

The composites now in use are initially paste-shaped and are called optical composites because they begin to harden in the presence of light. Composites are a mixture of materials called monomers, which harden in the presence of light and become a hard material called a polymer. As mentioned, these composites are in the form of a paste that the dentist can easily place in the cut cavity on the tooth and shape it as desired. It then polymerizes it using light to make it stiff.

 

The light used today to harden composites is the blue spectrum of visible light. So despite what some people mistakenly call a laser or ultraviolet, this light is the same as visible light. This light has a penetration power of about 2 mm of the composite. So the dentist should apply the composite layer by layer on the tooth and shine blue light for about 20 to 30 seconds each time to harden each layer and then apply the next layer. If the composite does not receive enough light, the material will not harden well and there is a possibility of breakage in the repair as well as discoloration and discoloration in the future. After the composite hardens, the dentist uses special tools and brushes to polish the surface to make it beautiful and shiny. Because there are so many different colors of composite, the dentist chooses the color that most closely resembles the color of the primary tooth.

 

Composite restorations should be checked annually by a dentist so that in the event of any repair defect, the tooth can be restored to prevent secondary caries. Another advantage of composite, in addition to beauty, is that this material has the ability to stick to tooth tissue using the arrangements used by the dentist. This eliminates the need for the dentist to cut the tooth too much (unlike amalgam, which requires more tissue to be cut from the tooth to prevent the restoration from separating from the tooth). Therefore, by using composites, more tissue of the tooth can be preserved. In addition to repairing caries, composite is used to repair broken front teeth, close interdental spaces, correct malformed teeth, and orthodontics to attach fixed orthodontic wires.

 

The important thing when working with composite is that the desired tooth and its surroundings should be as dry as possible to ensure maximum adhesion of the composite to the tooth. The dentist does this using cotton and strong suctions, and the patient must cooperate with the dentist at this stage. Composites are generally used in front teeth, because the issue of beauty in these teeth is very important. Today, new composites have been introduced to the market that are more robust and can also be used to fill posterior teeth.
