Why Do Teeth Stain?
Teeth stain due to food and drinks like coffee, tea, and red wine, tobacco use, ageing, certain medications, and poor dental hygiene. Stains can be surface-level or deep within the tooth enamel.
Professional vs At-Home Whitening
Professional whitening done at the dental clinic produces faster and more dramatic results. At-home kits with custom trays from your dentist are also effective. Over-the-counter products are less powerful and take longer to show results.
The Whitening Process
In-office whitening typically takes about 60 to 90 minutes. A protective barrier is placed on gums, whitening gel is applied to teeth, and a special light may be used to activate the gel. Most patients see results of two to eight shades whiter.
Is It Safe?
Professional teeth whitening supervised by a dentist is safe. Temporary tooth sensitivity and gum irritation are the most common side effects, which subside within a few days. People with sensitive teeth should inform their dentist before treatment.
Maintaining Your Results
Avoid staining foods and drinks for 48 hours after whitening. Brush twice daily, floss regularly, and use a whitening toothpaste. Touch-up treatments every six to twelve months help maintain your bright smile.
