Teeth whitening
Teeth whitening can give your teeth a brighter and fresher appearance. Discoloration can be caused by, among other things, coffee, tea, red wine, tobacco, colorful foods, or natural variations in tooth color.
At Bergen Dental Clinic, we always evaluate your teeth before whitening to ensure that the treatment is performed safely and gently.

In brief
Teeth whitening can give you a brighter smile in a controlled and safe way.
Before teeth whitening, you should have your teeth examined by a dentist. This is important to check your dental health, fillings, crowns, gums, and any sensitivity.
We also recommend thoroughly cleaning your teeth before whitening. In some cases, Airflow may be appropriate before the whitening process begins.
At-Home Teeth Whitening
For at-home teeth whitening, we create custom-fitted whitening trays that fit your teeth. The trays ensure that the whitening gel makes good contact with your teeth while reducing the risk of the gel coming into contact with your gums.
You'll receive clear instructions on how to use the trays, how much gel to apply, and how long the treatment should last.

- The rails can be reused later if needed
- The treatment is performed under the supervision of a dentist
- The result can be natural and even
Before Teeth Whitening
Before teeth whitening, your dentist must evaluate your teeth. This is to prevent complications and ensure that whitening is right for you.
You should also consider whether you need a dental cleaning or Airflow treatment before your treatment begins.
The dentist will explain which type of whitening is best for you, and you'll receive information about the expected cost before treatment begins.
After teeth whitening
After teeth whitening, you should avoid colored beverages and foods for a while. This includes, for example, coffee, tea, red wine, soda, and strongly colored foods.
It may also be a good idea to use fluoride mouthwash or fluoride toothpaste if your dentist recommends it.
Some people may experience temporary sensitivity after whitening. This usually goes away.
In-Office Teeth Whitening
In some cases, in-office teeth whitening may be an option. This procedure is performed at the dental office using a whitening agent and light to activate the treatment.
In-office teeth whitening can provide quick results, but your dentist will always assess first whether this is suitable for your teeth.
Is teeth whitening harmful to your teeth?
Teeth whitening is generally safe when performed following an evaluation and under the guidance of a dentist.
The bleaching agent used breaks down into water and oxygen. However, the treatment may cause temporary sensitivity or irritation of the gums if too much gel is used or if the treatment is not followed correctly.
You should not whiten your teeth if:
- You are pregnant or breastfeeding
- You are under 18 years of age
- You have untreated cavities or gum problems
- You have large, visible fillings or crowns in your smile
- You have very sensitive teeth
- The dentist believes that teeth whitening isn't the right choice right now
Fillings and crowns are not bleached. If you have visible fillings or crowns, it may be necessary to plan for this before treatment begins.
Cost of Teeth Whitening
The price depends on which type of teeth whitening is right for you and whether you need an examination or a cleaning first.
You will always receive clear information about the price before treatment begins.
