Amalgam is a commonly used dental material to treat and fill cavities. This has much to do with strength and durability; it is also the most inexpensive type of tooth filling compared to other options such as gold, composite or porcelain. Dental amalgam is made of an equal amount of elemental liquid mercury and an alloy powder containing silver, copper, tin and usually a small amount of zinc. However, due to an increasing emphasis on keeping smiles metal-free for health and aesthetic reasons, today fewer dentists recommend dental amalgam fillings as optimal dental treatment.
When a tooth is too damaged to support a tooth filling, but not damaged enough for a dental crown, you end up somewhere in between. Capping a damaged tooth unnecessarily with a dental crown removes more tooth structure than needed. But a large filling can weaken the remaining structure of the tooth, causing the tooth to break, crack, or eventually need a root canal.
When your are faced with the choice between a large tooth filling or a dental crown, do you save money now and risk major dental problems down the line or undergo possibly an unwanted dental treatment? Dental onlays fall somewhere in between dental fillings and dental crowns. Onlays restore large cavities without having to use a crown.
A porcelain onlay is similar to a dental crown in that it is designed to restore a tooth that is broken down so much that a filling is not enough to fix it. If too much of the tooth is missing, the tooth could fracture. A porcelain onlay covers most or all of the chewing surface of the tooth and strengthens it so it won't fracture.
A crown is a type of dental restoration which completely caps or encircles a tooth or dental implant. Crowns are often needed when a large cavity threatens the ongoing health of a tooth. They are typically bonded to the tooth using a dental dental cement. Crowns can be made from many materials. Crowns are often used to improve the strength or appearance of teeth. While arguably beneficial to dental health, the procedure and materials can be relatively expensive.
Tartar control toothpaste cannot remove previous tartar build up. Only a trained dentist or dental hygienist can scrape away the hardened calcium above and below the gumline. What this toothpaste does is halt the progress of the destructive chemicals responsible for the creation of tartar. The tartar cycle begins with food. When food particles are allowed to remain on the teeth after eating, bacteria begins to feed on them. These living organisms excrete acids that leech out calcium from the tooth enamel. A process called demineralization. Eventually, this process creates cavities and fissures in the tooth. This compound of calcium and acid combines with oxygen to form a substance called calcium phosphate. Calcium phosphate tends to bond with existing enamel along the gumline and work its way up the tooth. This is the hard, yellowish material that must be scraped away with metal tools. Calcium phosphate will continue to form as long as the cycle of acid production and demineralization remains unchecked. Brushing with regular toothpaste removes the acid deposits and food particles, but the tartar will remain.
The most important item to look for when choosing a toothpaste is naturally occurring mineral. It's use has been instrumental in the dramatic drop in tooth decay and cavity occurrence that has taken place over the past 50 years. Bacteria in your mouth feed on sugars and starches that remain on your teeth after eating. Fluoride helps protect your teeth from the acid that is released when this happens. It does this in two ways. First, fluoride makes your
Toothpaste is available in paste, gel or powder form. Despite the many toothpastes that exist, there are some ingredients common to most varieties. These include: Abrasive agents; Scratchy materials, including calcium carbonate and silicates, help remove food, bacteria, and some stains from teeth. Flavoring; Artificial sweeteners, including saccharin, are often added to improve taste. Humectants for moisture retention: Paste and gels formulations often contain substances like glycerol to prevent paste from drying out. Thickeners: Agents that add thickness to the toothpaste, including gums and gooey molecules found in some seaweeds help achieve and maintain proper toothpaste texture. Detergents: the suds you see when brushing, these are created from detergents like sodium lauryl sulfate.
