In-Office Teeth Whitening Side Effects
Pain and tooth sensitivity are common, though not all patients experience side effects. If teeth do become sensitive, the sensation should dull within 24 hours. Very 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. Bleaching treatments cannot be used to 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 In-Office Teeth Whitening
Teeth may be slightly sensitive for up to 24 hours. You won't be housebound, but you might have to lay off very hot or cold food and drink if you do experience increased sensitivity.
After care for in-office teeth whitening: After teeth bleaching, it may be best to avoid cigarettes, coffee, tea, and wine for up to 24 hours for best results.
