“I Wish My Teeth Were Brighter… What Are My Options?”

What is Teeth Whitening and How Can My Dentist Help?

Having stained, discolored teeth can be a challenge, especially when it comes to your confidence in your smile. Brushing your teeth can help you to remove surface-level stains, but stains that exist deeper within the tooth will need heftier treatment. Although there are many different over-the-counter options for teeth whitening, consulting with your dentist is always a good first step so that you know which products and professional treatments will work effectively and safely for you.

Tooth discoloration is a perfectly normal part of life. There are generally two types of teeth stains– the first are extrinsic, or external, and exist on the surface of the enamel. The second type is intrinsic, or internal, and these exist within the dentin and deeper layers of the tooth. Although avoiding stain-causing factors can be an effective way to stop stains from forming in the first place, you may need some professional help if your stains are deep-set or don’t respond to over-the-counter treatments.

What is Teeth Whitening and How Can My Dentist Help?

Food and Drink

Drinks like coffee, red wine, and dark soda are famous for causing teeth stains. However, there are plenty of other foods and drinks that can stain your teeth over time. It can be hard to avoid these sometimes, so making sure to rinse your mouth and brush regularly can help reduce stains from this food and beverages.


Tobacco, both smoking and chewing tobacco can cause substantial yellowing of the teeth with regular use. This is usually the result of a combination of tar and nicotine, and it can make your teeth yellow in a very short period of time. There are many reasons to quit smoking and avoid tobacco, and your smile is one of them.

Poor Oral Care Habits

Without regular brushing or flossing, it’s much easier for stains to set in and cause long-term discoloration. Regular brushing can not only prevent decay by removing harmful foods and bacteria from your teeth, but it can prevent them from causing stains over time.

Trauma or Medical Conditions

Some medical conditions can cause tooth discoloration by affecting the proper development of your enamel when you’re young. Additionally, trauma or injury to your teeth can result in discoloration. This means that even the best at-home care and lifestyle changes won’t achieve the results you want. In these cases, veneers and internal bleaching are necessary to mask stains.


Simply put, your teeth can become discolored as a result of aging. This is usually compounded by existing stains and the process of enamel breakdown as you age. There is also a process of reparative dentin deposition which causes the nerve space to shrink, creating an illusion of grayer tooth shade.

“I have been Dr. Chern’s patient for several years now and I have no intention of ever finding another dentist. When you find an amazing dentist, you stick with them. She’s honest, professional, and knows what she’s doing. Her staff is just as amazing.”

– David K.

The Zoom Bleaching Process and What to Expect


Dr. Chern will take a look at your teeth and assess what kind of whitening process will be best for you. She’ll also take pictures so that you can track your progress as your treatment unfolds. This is the best time to discuss your smile goals with Dr. Chern who can recommend your best options for cosmetic dentistry. We offer Zoom in-office teeth whitening as well as custom take-home trays to help you get your ideal results. Both are pain-free options to whiten and brighten your teeth safely with little to no issues with sensitivity.


Teeth whitening works best on clean teeth. Dr. Chern will perform a cleaning of the enamel that ensures you get the best results. Then, she’ll gently pumice your teeth to remove surface stains and apply a vitamin E balm to protect your lips during the whitening process. Your mouth will be isolated with retractors and a liquid dam to protect your lips and gums from the peroxide.


A hydrogen peroxide-based Zoom Gel is carefully applied to your teeth. This gel can work on stains deep in the tooth’s structure without affecting its health with the help of a specialized, light-based Zoom machine aimed at the teeth. The whitening process takes about 15 minutes, and you can relax, listen to music, or watch your favorite show during this time.

Repeated Treatments

You’ll receive about 3-4 applications of Zoom Gel depending on the level of whitening you’d like to achieve. Between applications, Dr. Chern will examine your teeth and make sure the treatment is working as planned, as well as track your progress and any issues with sensitivity.

Caring for Your Teeth After Whitening

Dr. Chern will give you detailed instructions on how to maintain your Zoom whitening results. The first 24-48 hours are the key to the success of Zoom whitening. General rules are:

  • Eating a healthy diet (avoiding sugary drinks and drinks that can stain your teeth)
  • Avoiding pigmented foods and beverages
  • Brushing your teeth twice daily for 2 minutes with a soft or electric toothbrush
  • Floss every day or use a water flosser (Waterpik)

Additionally, you can use our professional at-home treatment systems to touch up your results as needed– and to manage any stains that may form in the future to prevent them from becoming more permanent. Zoom whitening results last 9 months to 2 years depending on lifestyle choices. We recommend Zoom treatments yearly as part of your oral wellness maintenance routine.
