Teeth Whitening Now you can achieve whiter teeth with our tooth whitening treatments. Dr. St. Germain begins the procedure by taking an impression of your teeth. Using this impression, he then develops soft "trays" or molds of your teeth. At home you add a gel or peroxide to the trays and wear them for a half hour per day. Your teeth should be visibly whiter in approximately two weeks. Whether you're getting married and want a beautiful smile for your big day or you're in your 40s or 50s and want to look younger, teeth whitening can give you the smile you've always wanted. Call Dr. St. Germain's office today to find out if you're a candidate for our teeth whitening procedure.
