Curious to learn about teeth whitening? Below you’ll find answers to some of the most common questions we get asked at SF Dental.

Does teeth whitening damage my teeth?

No, modern teeth whitening solutions are perfectly safe and will not damage your tooth enamel or existing dental restorations.

I have crowns or veneers. Will teeth whitening change their color as well?

No, teeth whitening agents only affect your natural teeth. If you’re looking to go many shades whiter than your existing color, you may need to consider separate treatment for your existing restorations. Ask your dentist about the options.

Are teeth whitening agents toxic?

Not when used properly. Most of the substances used to whiten teeth are chemicals that are produced naturally by your body, including carbamide peroxide and hydrogen peroxide. However, the old saying “the dose makes the poison” applies. When used properly, teeth whitening agents are not toxic. But you can get too much of a good thing. That’s why you should conduct teeth whitening under the supervision of a dentist.

Does whitening toothpaste work?

These toothpastes will clean off surface stains, but they won’t change the color of your teeth. They are most useful as an upkeep routine after you’ve had your teeth professionally whitened.

How long will the whitening last?

It depends on the type of whitening treatment you choose and what kinds of food you eat. If you regularly consume teeth-staining substances like coffee or red wine, your whitening will not last as long. Generally speaking, patients who want to keep their original whiteness will need to come back for a touch-up treatment periodically. This might be as frequently as every six months, but it’s more usual for patients to go a year or two between whitenings.

Will my teeth become permanently sensitive?

No, any sensitivity from teeth whitening typically resolves within a few days.
