Fracture of the filling – split of the filling
It is a sad thing to say but human body can sometimes cause trouble. Teeth are not an exception. When something goes wrong with the tooth it is necessary to treat or restore it. Filling is a method of restoration of teeth used to treat defects usually caused by caries
. Some time ago metal (amalgam) and concrete fillings made of powder and water were widely used in dentistry. Some time ago they were replaced by chemically hardened fillings. Such fillings are a mixture of 2 pastes. Such mixture is used as a filling material. Nowadays even more effective materials are used. Light-hardened fillings are widely used in modern dentistry. Such fillings are also called gel-hardened or photopolymer. Such fillings are hardened under the influence of a special stomatological lamp.
Fillings are used to eliminate defects of teeth caused by caries. Though modern fillings are rather durable they will have to be replaced after some period of time. Analysts claim that dentists spend half of their time replacing old fillings for new ones.
There are 2 most widespread reasons why people have to replace their old fillings. The first one is split of the edge of the filling. The second one is recurrent caries
. These problems seem to be not very dangerous but it is worth mentioning that the more often you replace fillings the less effective they turn out to be.
Most dentists confess that when they replace the filling they use the same filling material that was used the first time. The thing is that the second filling will have the same defects and shortcomings as the first one. When the dentist replaces the filling, the size of dental cavity increases by 0,2-0,5mm. It makes the base of the filling (healthy dental tissues) weaker. It means that the new filling will serve for a shorter period of time and will be less durable. Eventually there are very few cases when teeth can be restored with the help of a new filling. In most cases endodontic (orthopedic) treatment will be more effective. Moreover, artificial dental crowns can be used. Though these methods of treatment are more painstaking than ordinary filling they turn out to be more effective in cases when the first filling fall out. Do not insist on replacing the filling as it can finally cause dedentition.
