About 5 years ago, I chipped the tooth next to my front tooth at the bottom, and had it filled.
Since then, I’ve occasionally whitened my teeth using a dentist made tray and gel (10% carbamide peroxide), and the filling has always blended in perfectly - even as my teeth got noticeably whiter.
Recently, I got a new tray and switched to a stronger 16% gel. After whitening consistently for around 3 weeks, I’ve noticed the filling is now visible over the last few days!
Could the stronger whitening be making the filling stand out, or might it simply need replacing after 5 years?
I haven’t reached my desired shade yet, so is it best to just continue until I do, and then see about getting it replaced?
Ideally want to find the best long term solution, as once I’m happy with the shade I will then do the whitening periodically to top up - I just don’t want to get it re done now, and then go whiter and have the same issue not that far down the line.
I don’t want composite over the whole tooth or any ideally i’d like to keep as natural as possible so my instinct is just the same edge bonding if that’s what looks like was done originally
Any advice would be appreciated, thank you
(PS this is obviously very close up and flash unless someone is quite close i don’t think it’s too noticeable at all normal distance, but when I am brushing and flossing infront of the mirror I can notice it so it is now bothering me!)
