Known as the Direct Dental Restorative, a filling is used to restore decayed part of a tooth which can be done in a single visit and will be the main topic of this article. We will provide you information on Indirect Dental Restorations in the subsequent article.
Dental Fillings
You can select from amalgam, resin ionomers, glass ionomers and resin composite fillings. You may want to confer all these alternatives with your family dentist before making the decision. You can get the best recommendations according to the form and treatment of the particular tooth in consideration.
Nowadays, you have several options available that may perhaps be a great development since there has been a slight controversy concerning amalgam fillings. The Food and Drugs Administration has considered the quantity of mercury in amalgam fillings harmless and non-toxic for patients six and above however, they have re-classed the filling as a Class II medical plan. This places the amalgam fillings at a “medium risk” phase, subsequently opening the door for stricter safety measures and more study.
Amalgam fillings are utilized in approximately a third of every dental restorative procedure. This application has been used for over a century. It is still widely used today because it’s durable and affordable. The mixture of elemental mercury, tin, silver, copper and probably some other metallic elements are the components in these fillings. It is deemed that the amalgamation of these metals stabilize and cause the mercury non-toxic. Amalgam fillings can resist very heavy chewing loads, hence are frequently placed in molars where chewing pressure is greatest.
More often than not, this filling is acceptably tolerable unless a patient develops an allergic reaction which is very rare. There can be roughly temporary sensitivity to cold and heat with a newly-placed filling and if this condition continues you should inform your dentist. Other drawbacks of amalgam fillings are, your dentist may need to take away more tooth construction to house an amalgam filling compared to other kinds of fillings and they aren’t as natural looking as the other restorative fillings.
When the chewing load will not affect the composition of this recuperative or the tooth, glass and resin ionomers are used. Oftentimes they are used when an amalgam filling would be unattractive and needless they are colored materials. Ionomers are made of either acrylic acids or fine glass powders or in case of resin ionomers, acrylic acids glass and acrylic.
Ionomers are often applied between teeth or upon the roots of teeth. Less tooth constructions are needed to be removed compared to an amalgam filling. Also glass ionomers can produce a little amount of fluoride for patients who have high risk for tooth decay.
Ionomers are used as fillings in primary teeth in children as well, if in a rare situation a restoration is necessitated.
One of the major disadvantages of ionomers is that they are actually used for small areas only and not in areas exposed to heavy chewing pressures because they have a lesser resistance to breakage.
Sporadically identified as filled resins or merely composites, these restoratives are a resin filler combined with a glass or quartz materials. Composite fillings are used when the areas of the removed decay are mid-sized or small.
Composites require less tooth material to be removed for the filling. The reality that the composite filling can be joined to the tooth with cement or be “bonded” is the explanation for this. Composite fillings have better resistance to fracture and can endure average chewing pressure. The materials and bonding agents for composite restoratives are both improving rapidly.
This kind of restorative has few challenges to be considered. One is that it needs little more time than an amalgam and the place to be filled has to be delicately kept dry and thoroughly clean. Second, is that composites are also a little subject to staining or yellowing with wear and tear. You may possibly need to ensure your dental insurance pays this type of restorative nevertheless it is increasingly accepted as it becomes more popular. The fact that it’s becoming more popular is just partly because of the aesthetic features as concerns about the mercury content in amalgam are the other reasons. In general, the cost is modest but not as cheap as amalgam fillings.
In conclusion, the types of direct dental restoratives or what all call “fillings” which can be performed in one appointment setting are:
Amalgam fillings are typically the most inexpensive and most commonly covered by insurance plans. They are used for filling big areas and can resist heavy chewing loads. Be conscious that it requires a more general removal of dental structures as compared to the other restoratives and new studies show that they are unsafe for children below six and not advised for pregnant and lactating women. More studies are desired to verify hazard to the general population.
Ionomers are for small usually noticeable areas of the teeth that are not exposed to heavy chewing stress. They blend with teeth in color and so are barely noticeable and are occasionally used for primary teeth of young children.
Composites, like the ionomers are formed with a blend of white resin and glass or other tooth-like substances. They are used normally for small to moderate fillings and don’t require as much tooth structure removed for restoration but are not used in very large areas because they will not take as much pressure as amalgam restorations. Whereas they are gaining popularity, a number of insurance plans do not cover this type of restoration and they are a bit more expensive.
