Teeth Whitening (Bleaching) Side Effects
Pain and tooth sensitivity are common. Occasionally, discoloration or bleaching of the gums can occur.
Who shouldn't use it: People with sensitive teeth and gums may think twice about having their teeth bleached. Neither at-home nor in-office bleaching treatments will whiten teeth with caps, crowns, or veneers.
Drawbacks: Teeth bleaching won't tackle discolorations that stem from the inside of your teeth (intrinsic stains). These types affect your tooth's dentin - the inner layer - and are most often the result of genetics and antibiotics like tetracycline.
Recovery Time For Teeth Whitening (Bleaching)
Pain lasts a day or two. Increased sensitivity usually fades after a week. You won't be housebound, but you might have to lay off very hot or cold food and drink for a few days.
After care for teeth whitening (bleaching): After teeth bleaching, it may be best to avoid cigarettes, coffee, tea, and wine for about 24 to 48 hours for best results.
