Anyone can get a whiter smile. Consulting with a dental professional would defiantly benefit you. If you had a bad experience in the past I would recommend interviewing several dentists to find one that will make you feel comfortable. Many dentists will offer a free dental consult. If it has been a while since you have had a dental checkup and cleaning you should try that first. You will be surprised the amount of stain on your teeth that can be cleaned off by a hygienist. After that your whitening will be more effective and the doctor can give you several options to whiten your teeth.
