If you have never had a cavity, good for you. Cavities are very common, especially in young people that eat and drink excess amounts of sugar and don’t practice proper dental hygiene. A cavity is simply a hole in your tooth. Bacteria eats away at the tooth’s surface causing severe decay and damages the tooth’s structure. Thankfully, the cure is simple in the form of fillings.
Fillings as the name suggest, just fill up the hole that is in your tooth. Fillings are necessary because they prevent the bacteria, which can cause severe decay and protects the inner pulp from bacteria. If you allow decay to continue, the inner pulp can become exposed to bacteria which can be extremely painful. In this case, the only remedy left for is to consider root canal therapy.
Composite fillings, or tooth-colored fillings, use a type of resin to restore decayed teeth. Composite fillings are also used for cosmetic enhancements, like repairing chipped teeth or to reshape disfigured teeth.
