Amalgam vs Composite Fillings: Essential Things To Know

By Elite Dental Group

There are two different kinds of materials available for dental fillings, composite resin and amalgam. Both of which are useful for preventing cavities and the spread of decay. But it can be difficult to decide which material to use for a filling. Some people may think that it doesn't matter which filling is used, but it does hold importance. First, we will talk about the pros and cons of each material to decide which is best for you. 

Amalgam Fillings

Amalgam can be described as a mixture of metals that is very popular and efficient for dental fillings. Sometimes it is called silver amalgam but it actually contains a combination of metals like silver, tin, mercury, and copper and there can be a small amount of palladium, indium, and zinc. This kind of filling is less expensive compared with other materials. It is very durable and considered as a superior choice for a filling when there are cavities or issues with the back teeth. 

One of the advantages of amalgam is that it hardens quickly and becomes beneficial in the areas that are problematic to keep dry during placement, like below the gum line. This kind of filling is great for kids because it takes less time than a tooth-colored filling. Many people are getting amalgam fillings every day. But there are some drawbacks to these fillings, this can cause tooth sensitivity. Along with that, they are more noticeable as they are large, and some silver spots may be seen.

It has been said that amalgam fillings can weaken the natural tooth and in time the tooth may break, shatter or split in half. Another disadvantage is that amalgam fillings can lead to some potential health risks that can range from autoimmune disease to even cancer. Along with health issues, a person may have allergies if they are sensitive to metals. After the procedure of amalgam fillings, the patient will have to follow a variety of instructions from the dentist to avoid certain types of foods and drinks.

Composite Fillings

They are also known as tooth-colored fillings that can repair a tooth that has been affected by fractures, cracks, decay, etc. The area that has been decayed or affected will be removed and composite filling will replace it. Along with amalgam fillings, this kind of filling is also widely used in modern dentistry. Since they are tooth-colored, they have a close resemblance to a person's existing teeth and is more aesthetically pleasing for front-facing teeth or teeth that are very visible. 

If a person has decayed teeth, worn teeth, chipped teeth, cracked teeth, or needs spaces closed between the teeth, composite fillings can be implemented. The dentist will numb the part of your mouth and remove the decay as needed. After that, the area will be cleaned and prepared carefully before the new filling is inserted. If the decay is present near the tooth’s nerve, the dentist may use a special medication for added protection. Then, a composite filling will be placed, shaped, and polished, restoring the tooth of the patient to its original shape and function.

The patient may experience some sensitivity to hot and cold foods and drinks when the filling is first placed. This may occur until the mouth gets used to the new filling. The cost of composite fillings can be more costly than other options. It also has a shorter lifespan and will last for about five to eight years. This procedure will take longer because the oral health practitioner will have to prepare the tooth. After that, the dentist will mix the solution of composite resin to create the correct shade and then place it in the tooth. Then there will be a bonding process to stick the material to the tooth.

Things To Consider When Getting A Material For Dental Filling

In order to determine which type of material is your best option, you can discuss this with your dentist. Along with that, the location of the filling is another thing to discuss. Remember, having cavities affects the material and process that will be used. The choice of a dental filling also depends on the size of the cavity. If the patient has larger cavities, the dentist will have to use a stronger material for the filling so that it will work as the stabilizer of the tooth.

Also, you should discuss your dental history with the dentist and anything that might affect the procedure. Lastly, try to remember that the best dental filling is no dental filling. If a person takes proper care of their dental hygiene, they should not need a dental filling. Brushing and flossing are two important ways to prevent cavities from occurring. You should also visit the dentist about twice a year for a checkup. Try to eat a balanced diet and make sure to rinse your mouth especially after eating something sugary or sticky. Read More.
