Options for tooth whitening in San Francisco

Dr. Leo Arellano at Leo Arellano DDS PC Explaining Teeth Whitening Options

People have appreciated the beauty of a brilliant white smile throughout history. Evidence has been found of primitive teeth whitening procedures used in ancient Greece and Rome thousands of years ago. These ancient societies used ingredients such as wine or urine. Thankfully, modern science discovered the benefits of peroxide based bleaching formulas.

In today’s image conscious society, a beautiful white smile is valued more than ever. There are also more formulas and methods for whitening than ever. Over the counter products, such as toothpastes and mouth rinses, yield unsatisfactory, if any, results. Commercially available strips and trays are slightly more effective, though they are much weaker than professional strength formulas. There is also a significant risk of burning soft tissues or causing tooth sensitivity when treatment is not supervised by a dental professional.

In office bleaching procedures, or custom trays from a dentist, are considered superior in safety, speed, effectiveness, and lasting results. There are many brands of professional teeth whitening. Dr. Leo Arellano offers several options, selected for their exquisite results and high level of customer satisfaction. Each has unique advantages, and the best choice is different for every individual.


The unique formula of Opalescence includes fluoride and potassium nitrate, which improves the health, as well as appearance, of teeth. These ingredients strengthen the enamel, and help prevent decay. In-office Opalescence treatment takes about an hour, and does not require the use of lights.

A take home version of Opalescence whitening is also available. It is gentle and effective, containing potassium fluoride to minimize sensitivity. Three strengths are available to meet the individual needs of each patient.
