Picture of Teeth Whitening
Many teeth-whitening systems are available, including whitening toothpastes, over-the-counter gels, rinses, strips, and trays, and whitening agents obtained from a dentist. Teeth whitening is ideal for people who have healthy, unrestored teeth (no fillings) and gums. Individuals with yellow tones to their teeth respond best.
