How long does tooth bleaching last?

One of the methods is tooth bleaching. Keep in touch with StrAIberry to know all about tooth bleaching and how long it lasts.

 

What is tooth bleaching?

Bleaching is one of the teeth whitening methods that help remove yellow stains without shaving the tooth surface. This method cannot completely change the color of the teeth, but it makes them relatively brighter. A small number of people have clear and white teeth. Teeth may change color over time and by growing older. Also, food particles and some drinks such as tea, coffee, raspberries, and all colored foods change the tooth color. Smoking can also cause teeth to turn yellow. Some people may also have spots under the surface of the teeth that may come from the use of certain antibiotics or small cracks in the teeth. In addition, several people have congenitally dull teeth, and bleaching can help them have whiter teeth.

 

Intrinsic stains versus extrinsic stains

Keep in mind that the degree and type of discoloration or stain of your teeth play important role in the method used for tooth bleaching. There are two types of tooth stains:

Intrinsic (internal): Caused by aging, trauma, infection, and medication. These deep internal stains are more difficult to remove, but a proper treatment method will be efficient in wiping them out.

Extrinsic (external): Caused by food, cigarette smoke, and beverages. Most bleaches only work on exterior stains.

Methods used for bleaching

In general, there are two methods for bleaching, Home Bleaching, and Office Bleaching. For both means, you should first talk to a dentist. It is better to have regular visits for oral care and do tooth bleaching if your dentist recommends.

  • Office Bleaching

In the chairside bleaching method, which is performed in the clinic, a high concentration of bleaching agents is placed on the teeth. The agents are usually highly-concentrated hydrogen peroxide or carbamide peroxide.

However, if the agent is not used properly and the doctor is not skilled enough, it may cause allergies in the gums and teeth, which will disappear after a short time.

Before using the bleaching agent, the dentist applies protective gels on the gums. Therefore, no bleaching agent touches the gum. There are different devices for activating bleaching gels, such as laser, plasma arc, LED, etc.

It is noteworthy to know that the type of bleaching agent determines the durability, not the device used for its activation. If you maintain good oral hygiene, a chairside (or in-office) procedure should provide long-lasting results for 1 to 3 years.

  • Home Bleaching

Tooth bleaching methods are designed to reduce stains, not remove them. If you maintain proper oral habits and keep your teeth clean, home products and dental procedures will be more durable.

  1. Whitening toothpaste

If you use whitening toothpaste twice a day, you will notice a change in color within 2 to 6 weeks. This method can last 3 to 4 months. You can also use this toothpaste on a weekly basis. The ingredients of this type of toothpaste play a major role. These materials include the following:

  • Clean water
  • Carbamide peroxide
  • Mild abrasives

But keep in mind that some people are sensitive to whitening toothpaste and after a while, their gums become inflamed. Also, using them for a long time makes the tooth enamel thinner and not only does not ameliorate the tooth appearance but also damages it.

The degree of whiteness created by the use of white toothpaste varies according to its ingredient. Abrasives, for example, remove only surface stains, but peroxide provides higher degrees of tooth whitening.

 

  1. Whitening mouthwash

It takes up to 3 months to see the effect of using mouthwash in tooth bleaching. These solutions usually contain hydrogen peroxide, and their daily use can eliminate low levels of surface stains. Of course, these washing solutions show their effectiveness when used to complement other treatments and alone do not have much effect.

Complications of tooth bleaching

The active ingredients in teeth whitening can cause allergies in the teeth and gums, which are usually not long-lasting. Prolonged use of any bleach with peroxide or abrasives may Cause discomfort for some people.

There is also the possibility of more severe side effects, which include:

  • Burning and irritation of the gums:

    This is more likely to occur in case of using a gel tray at home or office tooth bleaching. But if you completely cover your gums before treatment, you can decrease the risk. This condition is short term and causes no serious damage.

  • Gum whitening: The gums may turn white and lose their color for a short time.
  • Gastrointestinal irritation or discomfort: Of course, this cannot be considered a direct side effect of tooth bleaching. Swallowing a whitening product can cause a slight burning sensation in the throat or stomach ache.

In addition, some people experience pain during or after teeth whitening. In some cases, bleaching gels may enter tooth cavities or cracks on the surface and cause severe pain. If you encounter these cases, be sure to contact your doctor.
