What Happens During Tooth Whitening?

During tooth whitening, a safe bleaching agent is applied to your teeth to break down stains and discoloration. The process begins with a thorough cleaning to remove plaque and debris. Then, a protective barrier is placed on your gums to shield them from the whitening solution. The whitening gel is applied to your teeth, often activated by a special light to enhance results. This process typically lasts about 30 to 60 minutes, depending on the desired level of whiteness. After treatment, you’ll notice a brighter, more radiant smile. It’s a quick and effective way to boost your confidence! Laser whitening, also known as power whitening, is another type of teeth whitening system that a dentist can provide. A bleaching product is painted onto your teeth and then a light or laser is shone on them to activate the whitening. Laser whitening takes about an hour.

What Causes Tooth Staining?

Tooth staining is caused by consuming certain foods and drinks like coffee and tea, smoking, poor dental hygiene, aging, and certain medications, leading to discoloration.

Age

Tooth color darkens with age due to wear and stains. Teens see quick whitening results; twenties need more effort; forties require maintenance; fifties face stubborn stains.

Starting Color

We are all equipped with an inborn tooth color that ranges from yellow-brownish to greenish-grey, and intensifies over time. Yellow-brown is generally more responsive to bleaching than green-grey.

Translucency and Thinness

Genetic traits affect tooth translucency. Opaque, thick teeth appear lighter and respond well to bleaching. Transparent teeth, especially front ones, lack pigment and resist whitening.

Eating Habits

Regular consumption of dark foods and drinks stains teeth, while acidic foods erode enamel, making yellow dentin more visible over time.

Smoking Habits

Nicotine stains teeth with brown deposits that penetrate the tooth structure, leading to intrinsic discoloration over time, affecting the natural tooth color.

Drugs / Chemicals

Tetracycline during tooth formation causes stubborn gray or brown stains. Excessive fluoride leads to fluorosis, marked by faint white marks and mottling on teeth.
