Does Teeth Whitening Gel Corrode Dental Implants?

I have 4 dental implants that I got in 2017. At the time, my main concern was to replace my missing teeth because 3 of the 4 could be seen when I smiled. Now my implant crowns are discolored, and I want them whitened. I stopped smoking to get dental implants, paid thousands of dollars for them, and now they are darkening. Why would this happen? I know bleaching gel is safe for my natural teeth, but will it corrode my dental implants? Is there some way to protect the crowns when I whiten my teeth? Thank you. Nathan from Atlantic City, NJ

Nathan,

Thank you for contacting us. Dr. Lim would need to examine your crowns to determine why they are darkening, but we will answer your question about teeth bleaching gel and dental crowns.

Teeth bleaching gel will not whiten dental implant crowns

Teeth whitening gel does not corrode dental implants. The bleaching gel will not affect the implants, nor will it whiten your implant crowns. The main ingredient in the bleaching gel is carbamide peroxide, which is safe for your teeth and dental implants. But there are a few things to keep in mind.

  • Your dental implant crowns are ceramic. Ceramic is colorfast, and not even professional bleaching from a dentist can lighten the crowns.
  • If your dental implant crowns are visible when you smile, they will look even darker after you whiten your teeth.
  • If you want your implant crowns to match the color of your natural teeth, after you bleach your teeth, you will need new crowns.
  • The implant root forms, or screws, do not require replacement—just the crowns on them.

Consult with a Skilled Cosmetic Dentist

Dental crowns should not darken within a few years if you take care of them. Perhaps the crowns’ surfaces are faulty or damaged. We recommend scheduling an appointment with a skilled cosmetic dentist to examine your crowns. Also, a cosmetic dentist will discuss your goals for whitening your teeth and getting implant crowns to match.
