Is it a good idea to replace Amalgam fillings with composite?

Even if you brush twice a day and get routine dental cleanings, cavities can still occur. If you’re between the ages of 25 and 45 and do have fillings, they are probably amalgam.

Dental amalgam is a metal that’s used to fill in large cavities, usually in the back teeth. While there’s no scientifically proven evidence that you should remove amalgam, there are a few reasons why you may want to consider replacing them with composite-based fillings.

Your Filling is Loose

If you’ve had your fillings for a long time, it’s possible for them to come loose. If this happens, bacteria can get inside your teeth and cause an infection. If you feel like your filling is loose, you need to see your dentist as soon as possible and have it replaced.

Keep in mind that composite fillings actually bond to teeth making them stronger and less likely to loosen or crack over time. In addition, composite fillings may also reduce tooth sensitivity, something that’s seen quite often in patients with older amalgam fillings.

Possible Allergic Reaction

If you suffer from sensitivities or allergies, amalgam may not be suitable for you. Since amalgam fillings are a mixture of mercury silver and tin, it might best to replace them with composite-based fillings. Speak to your dentist about what type of fillings would be best.

Aesthetics

If you’re not comfortable smiling because of your amalgam fillings, replacing them is a viable option. Composite fillings are usually invisible to the naked eye, which means they’re not noticeable when you talk or laugh.

Longevity

Both amalgam and composite fillings are long-lasting. The difference between the two is that amalgam can last 10 to 15 years whereas composite filling may only last five to 10 years. That’s not saying that amalgam fillings are better than composites. In the end, it’s a matter of preference as well as the depth of the cavity and its location.

Final Thoughts on Fillings

If you’re concerned about your amalgam fillings, talk to your dentist. Depending on your dental picture and the extent of your cavities, they’ll determine the best way to treat your fillings.
