Amalgam Safety

FDA confirms Dental Amalgam Safety
Dental amalgam has been used by dentist for more than a century and currently remains a viable treatment option. Questions have been raised regarding the safe practice of using dental amalgam due to to presence of mercury in the material, but major U.S. and international science and health institutes have maintained that it is safe and effective material for use in dental restoration. On July 28th, 2009, the U.S. food and drug
administration on (FDA) issued a final ruling which stated that dental amalgam is a Class II (moderate risk) dental device. This classification places dental amalgam in the same class as gold and composite (white) fillings.

Your Guide to Cracked Teeth
With their more sophisticated procedures, dentist are helping people keep their teeth longer. Because people are living longer and more stressful lives, they are exposing their teeth to many more years of crack-inducing habits, such as clenching, grinding, and chewing on hard objects. These habits make our teeth more susceptible to cracks.
Why does a Cracked Tooth Hurt?
To understand why a cracked tooth hurts, it helps to know something about the anatomy of the tooth: Inside the tooth, under the white enamel and a hard layer called the dentin, is the inner soft tissue called the pulp. The pulp contains blood vessels, nerves, and connective tissue. When the outer tissues of the tooth are cracked, chewing can cause movement of the pieces, and the pulp can become irritated. When biting pressure is released, the crack can close quickly,resulting in a momentary, sharp pain. Irritation of the dental pulp can be repeated many times by chewing. Eventually the pulp will become damaged to the point that it can no longer heal itself. The tooth will not only hurt when chewing but also may become sensitive to temperature extremes. In time, a cracked tooth may begin to hurt all by itself. Extensive cracks can lead to infection of the pulp tissue, which can spread to the bone and gum tissue surrounding the tooth.

Why do I sometimes have pain after a filling?

The answer is "pulpitis".  Pulpitis is a condition in which the dental pulp (nerve) becomes inflamed.  Symptoms include increased sensitivity to hot, cold, sweet, and even routine chewing.  Anti-inflammatories, such as Advil or Motrin, help relieve the symptoms.
