Teeth Whitening

Teeth whitening is a cosmetic dental procedure that is used to remove stains and discoloration from the teeth and to brighten their natural color. The process typically involves the use of a bleaching agent, such as hydrogen peroxide or carbamide peroxide, that is applied to the teeth in the form of a gel or a solution.

Why might you need it.

There are several reasons why a person may choose to undergo tooth whitening. Some common reasons include:

  1. Discolored or stained teeth: Teeth can become discolored or stained over time due to factors such as aging, smoking, certain medications, and consumption of dark-colored foods and drinks like coffee, tea, and red wine. Tooth whitening can help remove these stains and restore the natural color of your teeth.
  2. Special occasions: People may also choose to whiten their teeth for special occasions, such as weddings, job interviews, or reunions, to enhance their appearance and boost their confidence.
  3. Aesthetic reasons: Many people simply want to improve the appearance of their teeth and enhance their smile. Tooth whitening can be a safe and effective way to achieve this.

It is important to note that not everyone is a good candidate for tooth whitening. For example, if you have certain dental problems, such as gum disease or cavities, your dentist may recommend that you address those issues before undergoing a whitening treatment. Additionally, tooth whitening may not be effective for certain types of stains, such as those caused by certain medications or excessive fluoride exposure. It’s always best to consult with a dental professional to determine whether tooth whitening is right for you.

The Procedure

Tooth whitening procedures can vary depending on the method used. Here are some common steps involved in professional tooth whitening procedures:

  1. Dental examination: Before the whitening treatment, your dental professional will examine your teeth and gums to determine whether you are a good candidate for the procedure. They will also check for any dental issues that may need to be addressed first.
  2. Cleaning: The dental professional will clean your teeth to remove any surface debris and plaque, which can interfere with the whitening process.
  3. Isolation: A barrier or protective coating may be placed on your gums to prevent the whitening gel from coming into contact with them.
  4. Application of the whitening gel: The whitening gel, which contains a bleaching agent like hydrogen peroxide or carbamide peroxide, is applied to your teeth. This gel may be activated by a special light or laser.
  5. Multiple applications: The whitening gel may be reapplied multiple times during the treatment, depending on the method used.
  6. Final cleaning: Once the desired level of whiteness is achieved, your teeth will be rinsed and cleaned.

The entire process can take about 60 to 90 minutes, depending on the method used and the extent of discoloration. Some people may experience tooth sensitivity or gum irritation after the treatment, which is typically mild and temporary. Your dental professional may recommend ways to reduce any discomfort and provide aftercare instructions to help maintain your new, brighter smile.


Aftercare is an important aspect of tooth whitening, as it can help maintain the results of the treatment and keep your teeth healthy. Here are some tips for aftercare following a tooth whitening procedure:

  1. Avoid food and drinks that can stain your teeth: For the first few days after the procedure, it’s best to avoid dark-colored foods and drinks like coffee, tea, and red wine, as well as acidic foods and drinks like citrus fruits and juices.
  2. Practice good oral hygiene: Brush your teeth twice a day with a fluoride toothpaste, floss daily, and rinse with an antibacterial mouthwash to keep your teeth and gums healthy.
  3. Use sensitivity toothpaste: If you experience tooth sensitivity after the whitening treatment, your dental professional may recommend using a toothpaste specially formulated for sensitive teeth.
  4. Schedule regular dental check-ups: Regular dental check-ups can help detect any dental issues early on and prevent them from becoming more serious.
  5. Consider touch-up treatments: Depending on the method used, the results of tooth whitening may fade over time. Your dental professional may recommend touch-up treatments to maintain the brightness of your smile.

It’s important to follow any specific aftercare instructions provided by your dental professional, as they may vary depending on the method used and your individual needs. By following these aftercare tips, you can help maintain the results of your tooth whitening procedure and keep your smile looking bright and healthy.
