Let us first understand what dental amalgam filling is and what is composite filling. The silver filling is a mixture of mercury, silver, copper, and tin. Mercury works as a catalyst to combine all the metals into a strong and durable substance. The dentist uses these filling because these are easy to work with and more durable. The cost of silver filling is considerably less than that of cosmetic filling.

The resin-based composite filling is the natural teeth colored substance which is a combination of acrylic resin and glass and plastic. These aesthetically natural fillings are not suitable for back teeth molars since those are rigorously used in chewing and has tremendous wear and tear.

Benefit and drawbacks of cosmetic filling are:

• They are more appealing in appearance than amalgam filling. Since it matches the teeth color, one need not be conscious about the look when they smile or open their mouth.
• The teeth enamel is preserved. No excessive drilling or grinding is required. In fact, most of such processes do not require anesthesia as well. Therefore, the teeth structure is preserved.
• Usually, the filling process is done in a single sitting, unlike other dental procedures which require multiple sittings. The material also hardens up in seconds enabling the patient to eat anything within few hours of the procedure.
• It restricts the cavity to spread into other teeth and hence helps in dental health.
• It can be reworked easily and fast. The refilling of the cavity can be done conveniently. Also, the cost of this process Is comparatively less than other dental procedures and is usually covered by medical insurance.

• You may experience tooth sensitivity post such procedure
• These composite filling are more expensive than amalgam filling.
• These fillings can discolor or stain due to exposure to tea, coffee, wine, etc. which may look weird.
• They tend to wear out faster than silver fillings and require extra care. Thus, are not suitable for molars.
• They can deteriorate due to extensive exposure to alcohol.

The general procedure of filling in composite filling involves
1. Dentist chooses the resin color which would match to your tooth color.
2. Next, the surface of the tooth is drilled to get clarity of extending of the cavity. Then a conditioning liquid is applied.
3. Now resin substance is applied to the affected area, and ultraviolet light or laser is used to harden the substance instantly.
4. Once the filling sets completely, the dentist shapes the teeth and polish it to match its sheen with that of other teeth, so that it looks as natural as possible.
