I just published a new blog on the Accord Dental website about something we see a lot in practice: patients assuming tooth bleaching is a simple, harmless cosmetic procedure that works for everyone.

In reality, there are some clear situations where whitening is *not* a good idea and can actually make things worse.

In the post, I cover:

* When tooth bleaching should be avoided (e.g., untreated decay, cracked teeth, gum disease, significant enamel loss, lots of anterior restorations, pregnancy/breastfeeding, younger patients, etc.)
* Common side effects like sensitivity, gingival irritation, and enamel changes
* Why certain types of deep intrinsic staining (tetracycline, severe fluorosis, trauma‑related discoloration) don’t respond predictably to bleaching
* Safer alternatives such as microabrasion, bonding, veneers, and focusing on treating sensitivity or gum issues first
* Why a proper exam and diagnosis matter before you decide to whiten

The write‑up is aimed at patients, but I tried to keep it evidence‑based and referenced (CDA position statement, FDI policy statement, literature reviews on bleaching effects, AAPD guidance, etc.).

If you’re thinking about whitening, or you have questions about whether you’re a good candidate, this might be a useful overview!
