"However, there will be times when your teeth color canâ¤™t be improved by makeup, particularly under bright lights. Likewise, while watching what you eat and drink is good in keeping stains away, they do little to restore the natural whiteness of teeth that may have been lost for a number of reasons. For North San Antonio locals, there is simply no substitute for Blanco dental services like those provided by Dr. Jairo Chavez, DDS, in regaining the brightness of teeth.With professional teeth whitening, you can restore your beautiful, confident smile. The dentist can prescribe mouth trays with whitening gels, or employ technologically advanced tools like lasers. These methods are highly safe and are much more effective than unsupervised, over-the-counter alternatives."
