I had porcelain veneers 10 weeks ago and I still have pain in my teeth. How long does it takes to feel normal again? (photos)

Hi Sally,
Thank you for your detailed explanation.  Tooth sensitivity in veneered teeth often times has to do with the amount of tooth reduction that is done.  Some teeth need more reduction than other teeth, especially when the bite is being corrected.
Reductions in the first layer of tooth structure (enamel) typically do not cause any sensitivity.  The second layer of tooth structure (dentin) is comprised of many microscopic canals or tubules that terminate at the pulpal tissue inside the root where nerves and blood vessels reside. Part of the adhesive procedure involves placement of an acidic solution that could contribute to sensitivity.  The veneer cement can also cause sensitivity.
Over time, the tooth builds more dentin tissue from inside the pulp.  This internal protection reduces the sensitivity.
It is normal if the sensitivity to cold you are experiencing remains for a few months.  Typically the sensitivity will become markedly improved after about six months, if not sooner.
If you are still experiencing sensitivity to cold after six months, go back for a checkup.
In the meantime, if you experiencing sensitivity to biting or your tooth feels high, go for an adjustment.
I wish you well.
All the best,
