Your Beautiful Smile - Should You Consider Replacing Amalgam (silver) Fillings?

Recently, the National Dental Practice-Based Research Network conducted a 24-month study to evaluate the long-term effects of amalgam and resin-based composite restorations. For decades, many dentists were leery of using composite resin for restorations, claiming that they often left open contact areas, pits and voids, tooth preparation margins and postoperative tooth sensitivity. However, there were problems with amalgam as well, including “difficulty in making tight contact areas, over-carving potential, overhanging amalgam material and postoperative sensitivity”. (Ref. 1)

Dental amalgam consists of a combination of mercury, silver, tin and copper. As a result, the finished product’s silvery color fails to take on the natural aesthetics of a living tooth. The closer the amalgam is to the front of the mouth, the more noticeable the silver color can be. Although many people have shown concern about the risks in mercury, it poses no threat when combined with the other dental material. (Ref. 2)

In the study, there was no conclusive evidence that favored the longevity of either resin-based composites, which blend in with the natural tooth and are more pleasing to the eye, or amalgam fillings. Instead, the variables that determined restorative longevity include age, sex, number and size of surfaces, and practice workload. Researchers suggest that clinicians should try to recognize risk factors on an individual basis in order to promote longevity. (Ref. 3)

While Dr. Palani would suggest replacing the silver amalgam with the more aesthetically-pleasing composite filling, the most desirable answer is to prevent the need for any fillings with daily brushing, flossing and routine cleanings. Our goal is to help our patients prevent the need for restorative care with professional exams and cleanings; providing you with a true Beautiful Smile!

5 Ways to Improve Your Smile!

Improve Your Smile in 5 Ways!

Cosmetic dentistry offers many options for people who are unhappy with their smile. There are five main ways to improve your smile for a natural and beautiful effect.

1 - Composite bonding: Using tooth colored composite material, your dentist can apply this to the surface of the tooth to repair chipped, broken, discolored, or decayed teeth.

2 - Composite fillings: These fillings are tooth colored and require less tooth removal than traditional silver (amalgam) fillings. Many people choose to have their amalgam (silver) fillings replaced with composite for a more natural look.

3 - Dental Veneers: Composite or porcelain veneers are adhesively bonded to the anterior (front) of the tooth to repair chips and cracks, or to correct severe tooth discoloration. 

4 - Teeth Whitening: Our teeth often become stained from smoking, foods, and poor oral hygiene. Using specialized whitening bleach either in the office or a lower-strength product at home, lightening your teeth can take years off your smile.

5 - Smile Makeover: These involved a comprehensive assessment of your oral health and your smile goals to improve your overall appearance. During a smile makeover, several dental procedures may be required to achieve the look you want.
