Regarding fire departments, what is the difference between a Battalion, Engine, and Ladder?
Lightning in one storm may be positively charged, the object it strikes will be negatively charged therefore attracting the lighting to it. Once the lighting has struck a negatively charged object, that object then becomes positively charged meaning the lightning is no longer attracted to it. Although lightning does strike places more than once, it's just a saying that lightning never strikes the same place twice.
Hello smoking is awful for staining teeth and fillings. Give that up and also certain foods and drinks are very bad for stains. Things such as coke and coffee, tea and dark coloured fruits and curry and red wine. Avoid harsh tooth pastes such as whitening ones as they can scratch the surface and then more stains can set in. Tooth paste from Colgate or Crest is good, normal type tooth paste. For your filling to stain so fast is not normal, unless you are living off curry and coffee and cups of tea all day. I have also read mouth washes with alcohol can weaken and scratch resin fillings too and shorten their life, but I use a mouth wash called Colgate Fluorigard and my dentist recommended it to me and my fillings are not stained that bad and some are over 10 years old. Is the filling surface smooth? It has to be smooth so stains cannot get onto it so easy. If you cannot give up drinks that stain, drink them through a straw which can help. Hope that helps.
