Will have to update this post soon.
According to Dentalblogs , the Philadelphia City Council is set to vote on the Mercury in Dentistry Bill which (if it passes) will require dentists to inform patients about the mercury content (50%) of amalgam fillings and that it could be hazardous to their health.
Some research indicates that amalgams with mercury (in excess, probably) can cause hair discoloration, hair loss, gum disease, migraines, memory loss, anxiety, mental lethargy, chronic fatigue, eczema, asthma, kidney disease, backaches, arthritis, and hormone problems. Not to mention Alzheimer�s disease, Parkinson�s disease, MS, ad other neurological disorders, DNA damage, and many others.
So why still use amalgam? It�s less expensive compared to aesthetic restorations. The ADA has already deemed amalgams as safe. But to be on the safe side, many dentists have voluntarily chosen to place only composite resin fillings because of their aesthetic appearance and safety issues.
Governments in Maine, New Hampshire, and California are also considering similar laws.
Amalgam, mercury, safety

A new dental implant procedure called the hybridge is a new technology pioneered by doctors to give people with a lot of missing teeth a good reason to smile about.
The procedure consists of teeth removal and the fastening a row of resin dentures to several mental implants. It appears to be very cost effective granted that the patient has a �mouthful of problems.� The procedure is also speedier than its other counterparts � try completing the whole process from a whole year to merely three weeks. The idea behind the procedure has been brewing for many years but it has only been recently that the actual process itself was formulated.
�It can be cost-prohibitive when you’re dealing with someone who has a full mouth of problems and they feel implants are too costly for them. This is a great way to do it fast and cost effective.�
Prices start at $15,000 to $20,000 dollars which amounts to half the cost of dental implants with porcelain crowns and bridges. Not bad, huh?
Up to now, the idea is still under patent consideration but the actual goal is to market the procedure nationally.
