My aviation Doctor - prob. the highest in his field said swallowing mercury isn't as bad as you think - most will pass out, causing no harm. That's why it's mad that the NHS has banned mercury thermometers.... On balance, it's the vapour that does the harm. If you have it your fillings then it is continually releasing vapour. Fact. Dentists who still give fillings with mercury in them seem to think mercury somehow changes when it's in teeth so it won't give off vapour and won't get into your body through your porous teeth!? So it's safe!? Ask any chemistry student/employee/dictionary!
Silver tooth fillings, or amalgams, are a mixture of mercury and an alloy of silver, tin, copper, and zinc. Mercury usually takes up about 50% of this mixture, thus making it toxic. There are safer alternatives, such as gold or porcelain, but these are weaker and more expensive than the conventional amalgams, so mercury is still favoured.
Some mercury is used in flourescent lamps, including CFLs. Many streetlights use mercury-vapor lamps. Many dentists still use mercury-silver amalgam to fill teeth. In the past it has been used in thermometer's or a means of closing circuits such as thermostats and tilt sensors. I am trying to help find a way to super-cool mercury to create a super-fluid that will power an anti-gravity electromagnetic torus. The problem is that mercury freezes solid it needs an anti freeze solution.
Mercury in every one of its compounds is extremely poisonous. It is still used in fluorescent lights, amalgam dental fillings, and some cosmetics.
Being the only metal which is liquid at room temperature mercury has some specialist uses: It is also used in barometers an manometers due to its high density. From this it has also become a way of measuring pressure in millimeters of mercury. It has also been used as liquid electrolyte for the production of chlorine and sodium hydroxide from the electrolysis of brine but is again being phased out in favor of safer alternatives. It is still sometimes used in electrical switches as a liquid contact. Mercury also used to be used as a component for dental amalgams for making fillings for teeth. This process has again been phase out due to health concerns but many people still have mercury containing fillings and crematoria are thought to emit about 5kg of mercury each year simply from dental fillings. The amalgam of 70% silver and 30% tin when mixed with mercury formed a pliable material that could be inserted into the tooth and the amalgam expanded as it dried to fill the entire cavity. However this amalgam has been replaced by a similar one made from 60% silver, 27% tin and 13% copper.
External Marketing, promoting your practice to potential prospects, is still a relatively new phenomenon for Dentists. It is still difficult for some Dentists to come to terms with the thought that it is acceptable to "advertise."
Yes. my doctor did.
yeah its just a little more difficult for the dentist to put them in.
no you can still get a cavity underneath the filling if you dont take care of them.
people say that she has had a hit with someone but still has fillings for Ashley cole so yes she does
awe. yes. the beautiful, handsome, Gerard Way does infact have fillings. He has a few in the bottom back of his mouth and a few on the top part of his mouth. oh well, hes still perfect. =]}
