I am about to have a crown placed on one of my teeth. It occurred to me I should probably touch up my teeth whitening. My dentist said that was fine and gave me some trays and opalescence. What he couldn’t tell me was how long to do the touch-ups each day and for how many days. Do you have any advice for me on that?
There is no definitive answer that fits every person when it comes to whitening touch-ups. However, I can give you some general guidelines. First, I’d ask you how white your teeth were when you first had your teeth whitening done. I’d also want to know if you were happy with that shade. If that is the case, then I’d work back toward that shade.
The great thing about whitening with trays is the amount of control you have over the results. How long you whiten in total is until you get the results you want. The results are much more dramatic in the beginning and then the whitening slows down. As to how long each day will depend on your level of sensitivity. If you are able to tolerate it, sleeping with the trays will give you the biggest bang for your buck each day. Your saliva slows down at night, which will keep the gel on your teeth longer, making it more effective.
One thing I will say is to give it two weeks after you finish before you have your porcelain crown made. For a short amount of time after you are done your teeth will still be releasing oxygen bubbles. You’ll want that to calm down before having the crown’s color finalized
I will admit to a tiny bit of concern that the dentist doing your dental crown doesn’t seem able to answer these basic cosmetic questions. You may want to ask to see some before and after images of porcelain crowns he’s done, especially on front teeth.
