Teeth Whitening

Professional teeth whitening uses peroxide-based bleaching agents to break down compounds that cause discoloration in natural teeth. As these compounds change, your teeth can appear lighter and brighter without reshaping the tooth or covering it with a restoration.

At Polaris Dentistry, our cosmetic dentistry options include Zoom Whitening and custom take-home whitening trays. Each approach offers different benefits depending on your preferred timeline, starting tooth shade, and sensitivity.

• In-office whitening: Professional whitening treatments performed at the dental office offer a convenient option for patients who want to see results sooner.
• Custom take-home trays: Dentist-guided whitening trays allow you to gradually brighten your teeth at home according to a recommended schedule.

Some whitening systems use a special light, while others rely on the whitening gel alone. A light doesn’t automatically guarantee better results. The whitening agent, treatment method, and condition of your teeth all play important roles.

During your consultation, Dr. Dhawan will evaluate your smile and help determine which whitening approach is appropriate for your needs.

Professional teeth whitening can improve many types of discoloration, but not every stain responds the same way. Yellowish teeth often respond more favorably than gray discoloration or staining associated with certain medications.

Common causes of tooth discoloration include:

• Coffee and tea: Dark pigments can gradually stain teeth, especially with frequent consumption.
• Tobacco: Smoking and other tobacco products can leave persistent yellow or brown stains.
• Aging: Changes in enamel and the underlying dentin can make teeth appear darker over time.
• Certain medications: Some medications can cause discoloration that may be more difficult to treat with traditional whitening.
• Food and beverages: Red wine and deeply colored foods can contribute to staining.

It’s also important to distinguish between surface stains and deeper discoloration. A professional dental cleaning may remove some surface buildup, while whitening treatments can address certain stains within natural tooth structure.

Keep in mind that crowns, veneers, and tooth-colored fillings do not respond to whitening gel the way natural teeth do. If you have visible dental restorations, Dr. Dhawan can explain whether whitening might create noticeable differences in shade.

A single tooth that has become unusually dark may also need an examination to rule out injury or another dental concern. Identifying the cause of discoloration helps us recommend the right next step.

Your whitening experience begins with an evaluation of your teeth and gums. At Polaris Dentistry, we want you to understand your options and feel comfortable with your treatment plan before moving forward.

During your consultation, Dr. Dhawan will discuss your whitening goals, review any history of sensitivity, and examine your teeth for concerns that could affect treatment. If you have cavities, gum inflammation, or another oral health issue, those conditions may need attention before whitening begins.

Once your teeth and gums are ready, we’ll explain the recommended whitening method and what you can expect.

For in-office whitening, the dental team takes steps to protect your gums before applying the whitening product. Treatment timing depends on the system used and your individual needs.

If custom take-home trays are recommended, we’ll explain how to apply the gel, how long to wear the trays, and how often to use them. Following these instructions helps reduce unnecessary irritation.

Whitening results vary from person to person. Your natural tooth shade, the type of discoloration, and your response to treatment all influence how much lighter your teeth may become.

Professional teeth whitening is generally considered safe when used appropriately, but temporary tooth sensitivity and gum irritation are possible side effects.

Some patients notice brief discomfort when drinking something cold or breathing in cool air. Others may experience mild gum irritation if whitening gel comes into contact with soft tissues.

If you already have sensitive teeth, let us know before beginning treatment. Dr. Dhawan can help determine whether whitening is appropriate and discuss ways to manage discomfort.

Depending on your needs, recommendations may include:

• Using toothpaste formulated for sensitive teeth.
• Adjusting the timing or frequency of whitening sessions.
• Taking a break between treatments if sensitivity develops.
• Following the recommended gel quantity and application instructions.

Using extra whitening gel or leaving products on longer than directed won’t necessarily produce better results. It can increase irritation instead.

If you develop significant or persistent pain, stop whitening and contact our office. Discomfort shouldn’t be something you have to push through to achieve a brighter smile.

Professional teeth whitening results can last for months or longer, but the duration varies. Your diet, oral hygiene habits, tobacco use, and natural tooth color can all affect how quickly stains return.

Whitening doesn’t permanently prevent discoloration. Fortunately, a few everyday habits can help maintain your results while supporting your overall oral health.

• Brush twice daily: Use fluoride toothpaste and a soft-bristled toothbrush to remove plaque and maintain healthy teeth.
• Clean between your teeth daily: Flossing or using another interdental cleaner helps remove buildup in areas your toothbrush can’t reach.
• Rinse with water after staining drinks: Water can help wash away some pigments after coffee, tea, or red wine.
• Avoid tobacco: Tobacco contributes to staining and increases your risk of other oral health problems.
• Maintain regular dental visits: Routine exams and cleanings help keep your smile healthy and address surface buildup.

Your regular dental exams and cleanings also provide opportunities to discuss changes in your tooth shade.

If your teeth begin looking darker again, ask us whether a whitening touch-up makes sense. Avoid combining several whitening products or increasing treatment frequency without professional guidance.

Is professional teeth whitening better than whitening strips?

Professional whitening offers the benefit of dental supervision and treatment recommendations tailored to your teeth and gums. Over-the-counter whitening strips can also lighten natural teeth, but they may not be suitable for all types of discoloration or sensitivity concerns. A dental evaluation can help you choose an appropriate option.

Can I whiten my teeth if I have crowns or fillings?

Yes, whitening may still be an option if you have crowns or fillings, but these restorations won’t change color with whitening gel. This can create a noticeable difference between your natural teeth and existing dental work. Dr. Dhawan can help you understand what to expect before treatment.

How quickly will I see teeth whitening results?

The timeline depends on the whitening method, your starting tooth shade, and the type of staining. In-office whitening may produce noticeable changes after a visit, while take-home trays typically brighten teeth gradually over multiple applications. Individual results vary.

Does professional teeth whitening damage enamel?

When performed or supervised appropriately, peroxide-based whitening is generally considered safe for healthy teeth. However, improper or excessive use can increase sensitivity and irritate gums. A dental evaluation and proper application help reduce these risks.

How often should I whiten my teeth?

There’s no single schedule that works for everyone. Some patients maintain their preferred shade for an extended period, while others may benefit from occasional touch-ups. Your dentist can recommend a schedule based on your dental health, whitening history, and goals.

A brighter smile starts with understanding your options. Whether years of coffee stains have changed your tooth color or you’re hoping to refresh your appearance before an upcoming event, professional teeth whitening may help you achieve the look you want.
