I have loads of composite fillings and a few amalgam fillings. I would like to whiten my teeth, but wondered if that is possible with all the fillings? On a separate note, would it be possible to switch out the amalgam fillings? If so, should I do that before or after the whitening?
Let’s start with the amalgam fillings. You can switch them out. However, it requires a special procedure to ensure you don’t swallow or inhale any mercury or mercury vapors. I would only do that with a mercury-free dentist who knows how to do a sanitary amalgam removal. Mercury is toxic so you do not want to risk any ingestion.
If the amalgam fillings are leaky, I would switch them out before getting your teeth whitened. Otherwise, the teeth will be sensitive during the teeth whitening. If they are not leaky, you can do it either way.
Teeth whitening will not impact your fillings. However, it will not whiten them either. If any of them are visible, you will want to do the whitening first, and then have the composite filling replaced afterward to match the new whiter color. Just be certain to give it a week or two between the whitening and the replacement so the color has time to settle.
