Teeth Whitening (Bleaching)

Teeth whitening is a cosmetic dental procedure that addresses discoloration on the surface or within the tooth enamel. The goal of this treatment is to lighten the natural tooth color, typically aiming to make the teeth at least two shades whiter. The process is individualized, as the natural shade of a person’s teeth may not be fully white due to genetic factors.

What Is Teeth Whitening (Bleaching)?

Teeth whitening (also known as bleaching) is a widely popular cosmetic treatment, especially during smile design procedures. Both men and women commonly opt for this procedure to enhance their smile, and it can be done as a standalone treatment for those seeking a brighter appearance.

How Is Teeth Whitening (Bleaching) Done?

Teeth whitening can be performed using two main approaches: internal whitening and external whitening. The appropriate method depends on the tooth’s current structure and color.

Steps:

1. Initial Cleaning: First, any surface stains or tartar buildup is removed, preparing the teeth for whitening.

2. Polishing: The outer surfaces of the teeth are polished to ensure they are smooth and ready for the whitening agent.

3. Shade Selection: The dentist determines the desired tooth color, takes photos, and confirms the patient’s approval before applying the whitening agent.

4. Application: A whitening gel is applied to the teeth, activated by light, heat, or laser, depending on the chosen method.

5. Duration: The treatment typically takes about 45 minutes. Multiple short sessions (15-20 minutes each) may be needed in one appointment.

Methods of Teeth Whitening (Bleaching)

1. At-Home Whitening: Custom whitening trays are made, and the patient applies a whitening gel for several hours, usually overnight.

2. In-Office Whitening: This technique uses laser, heat, or light sources to activate the whitening gel applied to the teeth. It typically lasts about one hour, delivering immediate results.

3. Combined Whitening: A combination of both in-office and at-home treatments may be used for optimal results.

Are There Any Side Effects of Teeth Whitening (Bleaching)?

While whitening gels may cause slight enamel wear or tooth sensitivity, these effects are generally minimal. Sensitivity often resolves within 24 hours. Other rare side effects include:

• Enamel softening

• Sensitivity to temperature (hot and cold)

• Possible minor burns to gums or lips from the gel

• Temporary opacity or discoloration (which typically resolves as teeth rehydrate)

These effects are generally temporary and mild when applied by a skilled dentist.

Why Do People Need Teeth Whitening (Bleaching)?

Teeth whitening is commonly sought for:

• Genetic factors causing yellow or grayish teeth

• Staining from food, beverages (like coffee, tea), or smoking

• Aesthetic concerns leading to a desire for a more vibrant smile, often as part of a smile design procedure.

Even individuals with otherwise well-aligned teeth may seek whitening for a brighter, more youthful appearance.

Will Sensitivity Occur After Whitening (Bleaching)?

Minor tooth sensitivity is common after whitening, particularly within the first 24 hours. This sensitivity is usually temporary and resolves quickly. Some patients may also feel discomfort when consuming hot or cold beverages, but it typically disappears after the initial 24-hour period.

Does Teeth Whitening (Bleaching) Harm Tooth Structure?

Teeth whitening treatments do not damage the tooth structure when performed correctly. The enamel is naturally durable and resistant to wear. Modern whitening treatments are gentle on the enamel, and when conducted by an experienced professional, the risk of damage is minimal.

How Do Teeth Lose Their White Appearance?

Over time, teeth may lose their brightness due to exposure to staining agents like coffee, tea, or smoking. Without regular care, plaque and stains can accumulate in the porous enamel, darkening the tooth color. Professional whitening treatments can effectively address deeper stains, restoring a natural white appearance.

Teeth Whitening (Bleaching) Centers

While many clinics now offer teeth whitening services, it’s important to choose a reputable clinic with experienced professionals. Researching a clinic’s credentials, the expertise of its dentists, and reviews from previous patients can help ensure high-quality treatment and optimal results.
