Fillings restore full health and functionality to a tooth effectively. Dental filling procedures are most commonly used to treat cavities, but they’re also used to repair teeth that have been worn down over time.
What is a dental filling
A filling is a way to restore a tooth damaged by decay back to its normal function and shape.
When a dentist gives you a filling, he or she first removes the decayed tooth material, cleans the affected area, and then fills the cleaned out cavity with a filling material.
By closing off spaces where bacteria can enter, a filling also helps prevent further decay.
Most dentists make today’s fillings from composite resin.
Many dentists still use silver amalgam and glass ionomer fillings, too.
Materials used for fillings include gold, porcelain, a composite resin (tooth-colored fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).
When to get dental fillings?
Most people need at least one tooth filling in their lifetime, mainly because of cavities.
A cavity is a hole left behind after tooth decay destroys part of a tooth.
The cavity in the tooth still contains the bacteria that created it. Left unchecked, this decay will continue to spread and damage the tooth.
Removing the decay prevents further damage, but it doesn’t fix the damage to the tooth that already occurred.
That’s where fillings come in; by restoring the strength and integrity of the tooth and prevent decay from re-entering the vulnerable area.
