First, all teeth whitening products contain peroxide, but the concentration of the peroxides varies widely. High concentrations of peroxide can cause burning of the gums and soft tissue in the mouth and throat, and cause sensitivity on the teeth.Why do you need consult before whitening?
To identify the cause of the discoloration, caries, trauma (non-vital), medication (minocycline), resorption and make sure there is no contraindication for whitening.If I have sensitive teeth, what options do I have?
Patients with sensitive teeth, receding gums, or with defective restorations should consult with their dentist prior to using a tooth whitening system. Sensitivity from using a tooth whitening agent is usually temporary and disappears within 1-3 days of stopping treatment. However, we would recommend using a lower percentage whitening gel for a shorter period of time.
Another option is to use desensitizer agent gel (potassium nitrate) before or after each whitening session. This agent works fast to alleviate discomfort in 20-30 minutes.Can you whiten teeth faster with chairside bleaching?
Yes. In-office bleaching or chairside whitening agents use much stronger concentration to deliver rapid results. Opalescence Boost is a 38% hydrogen peroxide gel that is carefully applied by a dental professional to give your teeth a dramatic "whitening boost" in less than an hour. You would then continue your whitening treatment with a take home Touch-up kit.How long does it take to achieve the desired results?
Typically, a whitening treatment will take 7-14 days, depending on the degree of staining of the teeth, the location of the staining (enamel or dentin), and the concentration of the active ingredient in the tooth whitening gel. Yellow and brown staining will disappear fastest on about 10-14 days. Blue/gray staining could take 2-4 weeks, and tetracycline stains could take up to several months to disappear as they are usually deeply embedded within the tooth.How long does whitening last?
Bleaching results are usually stable, but your nutrition and lifestyle habits may dictate additional bleaching treatments. A touch-up now and again is easily done with home bleaching agents.Why dentist supervised whitening vs over the counter products?
