The filling is used to restore the teeth to their normal shape, appearance and function by filling the cavities caused by the cavities. Crack sealants are of great value in the prevention of tooth corrosion because they fill the natural pits and cracks of the most common back (molar) teeth that are corroded by teeth.

Filling

Fillings are more common in molars (rear teeth) with a higher rate of caries. Properly clean your teeth and maintain a healthy diet can eliminate the need for filling your teeth. Regular dental health checks will ensure that any problems are identified and treated early.

Types of filling materials used by dentists may include:

• Tooth color filling
• Dental amalgam (silver)

Other forms of dental restoration, such as gold or ceramic crowns, are an expensive alternative to amalgam and tooth color filling materials.

White filling

Tooth color (white) fillings have been used for the beauty of anterior teeth for many years. Recent improvements in posterior filling materials mean that these materials are now cheaper and are widely used as a substitute for dental amalgam.

Silver filling (dental amalgam)

Dental amalgam ("silver filling") is an inexpensive, durable material commonly used to fill teeth. Modern dental amalgam is a metal alloy, usually composed of mercury, silver and tin, containing small amounts of copper and zinc.

The chewing surface of the molar contains natural pits and grooves (cracks) where caries occur most often. The toothbrush bristles are too large to reach into some of these areas. Thoroughly clean and dry your teeth before applying the sealant. The liquid sealant is placed on the surface of the tooth and flows into the pits and cracks. The liquid is then irradiated with ultraviolet light. The pits and cracks are now sealed, the tooth surface is smooth and easy to keep clean.
