Brushing with toothpaste is important for several reasons. First and foremost, a toothpaste and a correct brushing action work to remove plaque, a sticky, harmful film of bacteria that grows on your teeth that causes cavities, gum disease and eventual tooth loss if not controlled. Second, toothpaste contains fluoride, which makes the entire tooth structure more resistant to decay and promotes remineralization, which aids in repairing early decay before the damage can even be seen. Third, special ingredients in toothpaste help to clean and polish the teeth and remove stains over time. Fourth, toothpastes help freshen breath and leave your mouth with a clean feeling.
How much toothpaste?
Contrary to what toothpaste commercials show, the amount of paste or gel needed on your brush for effective cleaning does not have to be a heaping amount. Simply squeeze a pea-sized dab of paste on the top half of your brush. If you brush correctly, holding the toothbrush at a 45-degree angle and brush inside, outside and between your teeth, the paste should foam enough to cover all of your teeth. Children under age 6, however, should be given a very small, baby pea-sized dab of toothpaste on their brush.
What type of toothpaste?
As long as your toothpaste contains fluoride, the brand you buy really does not matter, neither does whether or not it is in paste, gel or even powder form, or containing a certain flavor. All fluoride toothpastes work effectively to fight plaque and cavities and clean and polish tooth enamel. Your toothpaste brand should bear the ADA (American Dental Association) seal of approval on the container, which means that adequate evidence of safety and efficacy have been demonstrated in controlled, clinical trials

What is Dental Amalgam (Silver Fillings)?
Most people recognize dental amalgams as silver fillings. Dental amalgam is a mixture of mercury, silver, tin and copper. Mercury, which makes up about 50 percent of the compound, is used to bind the metals together and to provide a strong, hard, durable filling. After years of research, mercury has been found to be the only element that will bind these metals together in such a way that can be easily manipulated into a tooth cavity.
The main concern with most patients is of the mercury element in amalgam fillings. Mercury in dental amalgam is not poisonous. When mercury is combined with other materials in dental amalgam, its chemical nature changes, so it is essentially harmless. The amount of mercury released in the mouth under the pressure of chewing and grinding is extremely small and no cause for alarm. In fact, it is less than what patients are exposed to in food, air and water. Claims of diseases caused by mercury in amalgams have not been proven scientifically.
Dental amalgam has withstood the test of time, which is why it is the material of choice. It has a 150-year proven track record and is still one of the safest, durable and least expensive materials used to a fill a cavity. Alternatives to amalgam, such as cast gold restorations, porcelain and composite resins are more costly. Gold and porcelain restorations take longer to make and can require two dental appointments. Composite resins, or white fillings, are aesthetically appealing but require a longer time to place the restoration.
