The motivation behind a patient's decision to whiten their teeth might seem rather self-explanatory, as everyone aspires to achieve a bright, white smile. However, each patient’s circumstances vary, and they might choose to whiten their teeth for various reasons:

Discoloration

Tooth whitening can counteract discoloration caused by tartar, plaque, or other oral health factors. A diet featuring stain-causing products like coffee, tea, or wine can also be addressed with a whitening solution.

Significant Events

Whether it is anniversaries, birthdays, weddings, or job interviews, teeth whitening can enhance your smile and leave a memorable first impression.

Offset the Aging Process

As you age, tooth enamel tends to wear down, inviting discoloration and other oral concerns. A reliable teeth whitening product can help preserve a healthy, lovely smile.

Improve Self-Confidence

Discoloration can dampen your confidence, but you can restore it with a whitening solution.

Treatment Overview at Home

At-home tooth whitening options contain 3 to 20 percent peroxide, either as carbamide or hydrogen peroxide. The timing of application is crucial; longer application times result in whiter teeth, but higher peroxide percentages should be used for shorter durations to avoid dehydrating the teeth and increasing sensitivity. Before using any teeth whitening solution, consult our dentist to determine the best course of action.

Strips and Gels

These peroxide-based products are typically applied directly to the teeth once or twice daily for up to two weeks. The results can last for about four months. Crest 3D Whitestrips, which are dentist-approved and affordable, are a popular choice.

Tooth Bleaching Systems

This method uses a tray resembling a mouthguard filled with peroxide-based bleaching gel or paste, worn for one to several hours daily for up to four weeks. These systems can be purchased over-the-counter or custom-fitted by our dentists at Woo Dental in Newmarket.

Whitening Toothpastes

Whitening toothpastes contain chemicals or polishing agents that remove stains without using a bleaching agent. They are affordable and can brighten teeth by one shade but are limited to surface stains and should not replace professional cleanings or whitening treatments.



Treatment Overview from a Dental Office

Dentists use tooth-whitening solutions with 15 to 43 percent peroxide, a much stronger mix than over-the-counter kits. They may use heat, light, or both to accelerate the whitening process. Achieving the best results, often multiple shades lighter, typically requires dental appointments lasting 30 to 60 minutes. Some dentists can complete the procedure in a single two-hour session.

Noteworthy Side Effects

While teeth whitening is generally safe and risk-free, there are a couple of minor side effects to be aware of, such as temporary tooth sensitivity and slight gum irritation. It's important to note that these effects are typically mild and temporary, and can easily be managed with proper care and communication with your dental professional. In rare cases, some individuals may experience increased sensitivity to hot or cold temperatures, but this usually subsides quickly. Ultimately, the vast majority of people who undergo teeth whitening procedures have a positive and successful experience with no significant complications.

Tooth Sensitivity

Your teeth may become extra sensitive after the first or second treatment. If this sensitivity persists, your dentist can prescribe products containing potassium nitrate and sodium fluoride gel to alleviate discomfort.

Irritated Gums

Gingival irritation may occur due to contact with the whitening solution, but this side effect usually fades after treatments.

Who Cannot Whiten Their Teeth?

Certain patients are not suitable candidates for teeth whitening. Children under 16, who have larger pulp chambers, might experience irritation from whitening solutions. Patients with allergies, particularly to peroxide, and those with sensitivities should consult their dentist. Individuals with multiple restorations like fillings, crowns, or dental bonding might not be ideal candidates, as restorations do not respond to whitening and can result in an asymmetrical appearance. Pregnant and lactating women are also discouraged from whitening their teeth.

Which Option Is Ideal for You?

Choosing the right tooth whitening treatment is a matter of preference and budget. Some patients may have fewer options based on their dental condition. Not all tooth discolorations respond equally to bleaching. With the guidance of a dentist, patients can identify the cause of discoloration and determine if bleaching is practical. Patients with root canal treatments, fillings, crowns, or dark stains on anterior teeth should approach whitening cautiously. Regardless of the choice, remember that teeth whitening is not permanent. Moderation is key, and occasional whitening treatments can help maintain a bright smile.



Teeth whitening solutions have evolved significantly, offering both at-home and in-office options to suit various needs and preferences.
