But didn't you say in an earlier post that you had bonding on the teeth that was removed for some reason? If so, the enamel is probably not as smooth allowing stain an easier place to attach.
Only on the central incisors (the dentist "corrected" their misaligned height instead of telling me to get braces, LOL). But the staining is everywhere. I now do wonder if it's due to enamel loss due to braces.
4 weeks since my in-office whitening and they look like hardly anything has been done. I do have a take home kit. I plan to use it one night a month and maybe see a dental hygienist more often (once every 2-3 months maybe). But TBH I sort of stopped caring. I started drinking wine again. I may even start drinking tea again after a 2 year break. Looking back on it, I wonder how the hell I tolerated braces for almost 20 months (albeit only 13 months of upper braces).
