TOOTH SENSITIVITY: Although uncommon, some people can experience some tooth sensitivity during the first 24 – 48 hours after the whitening treatment. People with existing sensitivity, recently cracked teeth, micro-cracks, open cavities, leaking fillings, or other dental conditions that cause sensitivity may find that these conditions increase or prolong tooth sensitivity after the treatment. If you experience tooth sensitivity after the treatment, you can use SensodyneTM toothpaste to ease the discomfort. Brush your teeth with this toothpaste until tooth sensitivity goes away. If you have tooth sensitivity do not begin with your touch-up pen treatment at home. Wait until the sensitivity goes away and then begin with the home treatment.
BLANCHING: Sometimes the gums will turn white and possibly even sting a little, particularly with a professional teeth whitening treatment. This is called blanching and is very temporary. Rinse well and apply some vitamin e to the irritated gum area (optional). Gums should return to normal within 5-20 minutes.
COLOR REGRESSION: After the treatment, it is natural for teeth color to regress somewhat over time. This is normal and should be very gradual, but it can be accelerated by exposing the teeth to various staining agents, such as coffee, tea, tobacco, red wine, colas, citrus drinks and fruits, etc. Do not eat or drink anything except water for the first hour after the treatment because the gel opens the pores of the enamel and makes the teeth very vulnerable to staining agents. If you purchased a touch-up pen or a take-home kit (which is highly recommended in order to avoid color regression) be aware that the pores of your enamel will remain open for as long as you use it so you should refrain from staining agents till you stop using the pen. You can resume your normal habits 24 hours after you conclude the touch-up pen treatment. Also, be aware that drinks and food are not the only things that can stain our teeth when the pores are open; lipstick, for example, can stain too. Do NOT apply lipstick soon after whitening your teeth.
ALLERGIC REACTION: Some people are allergic to peroxide but are not aware of it. If you had the treatment done and a few hours or a day later you have blisters on your lips, you are probably having an allergic reaction. If severe, call your doctor right away, otherwise buy liquid vitamin E in any drugstore and apply it to the blister until it goes away. It generally goes away within a couple of days by itself.
