Dental caries is a disease that occurs when the enamel and dentin are destroyed by the action of acid (from food or plaque) and forms a cavity.
Once the enamel is penetrated, the cavity progresses faster through dentin and reaches the pulp, causing inflammation and infection. Fillings are the most common treatment of cavities. The dentist will remove the entire affected area and fill the cavity with a tooth colored material.
Traditional amalgam fillings have been used for over a century. They resisted very well but the disadvantage is that they are unaesthetic and can be seen when you smile or laugh.
Composite fillings may be an alternative in many situations. Over time, technology has advanced and now composites have gained much better properties, becoming more resistant over time and more compatible with dental tissue. Composite colors can be mixed to obtain natural color of the tooth, so that in most cases, fillings become invisible.
Therapeutic process to achieve physiognomic fillings is as follows: if there is tooth caries first clean the cavity with a milling until it remains only the healthy structure of tooth. If cleaned cavity is close to the pulp chamber (nerve), then a material called calcium hydroxide is added to achieve protection at this level. After the cavity is prepared, washed, degreased (using a sponge with alcohol or oxygenated water), is dried (with the spray from unit) and a gel is applied – phosphoric acid to create retention (microscopic channels) in tooth structure. This acid after a few seconds is rinsed, we dry the mouth again and apply adhesive solution -the bonding (substance that sticks the fill to the root). This bonding is photopolymerized with ultraviolet lamp (light blue).
In the end the composite material is added which will mold on the missing tooth area. Finally the filling is both molded and photopolymerized , so that all the material submitted to become harder. They can be molded and finished to create as much as possible, the natural look of tooth.
With composite fillings you can smile without leaving any clue that you have been to the dentist.
