ZOOM! Teeth Whitening FAQs

ZOOM! is a teeth whitening process that lightens discoloration of enamel and dentin.

There are many causes. The most common include aging and the consumption of staining substances such as coffee, tea, sodas, tobacco, red wine, etc. During the formation of teeth, consumption of tetracycline, certain antibiotics, or excessive fluoride may also cause tooth discoloration.

Almost anyone! However, teeth whitening may not be as effective for some as it is for others. We can determine if you are a viable candidate for ZOOM! Teeth Whitening through a thorough oral exam, including a teeth shade assessment.

More people whiten their teeth than you might imagine. A bright, sparkling smile can make a big difference for your overall appearance. The ZOOM! Teeth Whitening System makes it easier and faster than ever before.

Yes, extensive research and clinical studies indicate that whitening teeth under the supervision of a dentist is safe. In fact, many dentists consider teeth whitening the safest cosmetic dental procedure available. As with any teeth whitening product, ZOOM! Teeth Whitening is not recommended for children under 13 years of age and pregnant or lactating women.

By following some simple post teeth whitening care instructions, your teeth will always be lighter than they were before. To keep your teeth looking their best, we recommend flossing, brushing twice daily, and the occasional touch-up with ZOOM! take-home gel. These are professional formula products designed specifically to keep your teeth their brightest. They are available through our office.

Yes! Over-the-counter teeth whitening strips, brush-on gels, and toothpastes take weeks or months to whiten your teeth just a few shades. ZOOM! is clinically proven to whiten your teeth in 45 minutes. Only a dentist can get your teeth white this fast.

General FAQs

We are happy to process and file insurance claims for most dental insurance providers, and we always work with patients to fully understand their coverage, out of pocket expenses, and financing options as part of the treatment planning process.

We accept payment in cash and major credit cards. If you need extensive or long-term care, we offer CareCredit® to help you finance your treatment. In most cases, qualified applicants are able to receive low or no interest financing through CareCredit®.

Many of the patients we see each year experience some level of dental fear or anxiety. It’s perfectly normal. We work hard to help patients feel welcome and relaxed throughout treatment, but for those patients who need a little extra help relaxing, we offer dental sedation. Ask about your sedative options during your next visit.
At Oak Hill Dental, digital dental x-rays cut your radiation exposure by up to 90 percent and create high resolution digital images for improved diagnostics. These images make it easy for us to zoom in and highlight certain areas, which we can then show you so you can better understand our recommended treatment plan. If you are pregnant or believe you may be pregnant please let our dental staff know.
If you have a dental emergency, you should call our office as soon as possible. We make emergencies a priority, and we are happy to work you into the schedule. If your emergency occurs outside of business hours, call our office for Dr. Cantu’s emergency phone number.

Nearly anyone who is missing one or more teeth, and desires a superior, long-lasting aesthetic result is a good candidate for dental implants. However, patients must have enough bone to support and stabilize the implant. Some individuals who have suffered bone loss as a result of gum disease or another condition may need bone grafting before a dental implant can be placed successfully. Call our office today to book your complimentary implant consultation.

The American Academy of Pediatric Dentistry recommends children have their first dental exam at 12 months. Children begin erupting their primary, or “baby” teeth, around 6 months of age, and therefore should be seen by a dentist soon after in order to detect problems early. We make each experience a positive one so your child will develop a good relationship with Dr. Cantu and our team.

In general, it is recommended that you receive a teeth cleaning and check-up once every six months for preventative care. If you have a high risk for dental disease you might need to visit every three or four months, or more. Dr. Cantu will advise you on how often you should visit, based on the health of your teeth and gums.
