From black to white - replace amalgam filling.
Amalgam has been used filling as dental material for cavities for the past 150 years. It's also called silver filling, mercury filling and black filling. Even though it doesn't look nice cosmetically, scientific researches show that it's safe as dental material. It only needs to be replaced when it has defects, cracks, or decays.

Fix a broken tooth.
When a tooth breaks to the gum line, it may be extremely difficult to fix it and that's why an extraction is often recommended.

A better filling makes you feel better.
Symptoms: Tooth felt sensitive. Food got impacted between teeth. Problems: Defective filling with marginal leakage and open contact between teeth. If it had been left un-treated, it would have caused decays on the tooth and the adjacent tooth, gum inflammation and infection because of food impaction. We replaced the old filling. On x-ray, it showed that the new filling achieved tight contact with good margin. No more food impaction - a better filling makes you feel better.

In some cases, it may require orthodontic treatment (braces) to close the gaps between teeth. However, in some not severe cases, simple composite bonding can be an easy, quick and much more affordable option. It's also very conservative compared to traditional veneers . #Compositebonding

Close the gap.
Right central incisor missing. Gap between right lateral incisor and left central incisor. Orthodontics to create space and dental implant for missing incisor would be the best treatment option. But this less expensive and quicker treatment of composite buildup to close the gap was the patient's choice - still pretty good result. #Compositebonding
