Teeth whitening can be achieved by two basic methods. At home teeth whitening or in office teeth whitening. First the patient must understand how whitening works and what to expect. The two methods are further explained at the end of this paragraph.

Teeth whitening should always be done under the supervision of a professional with professional products. It is not advised to buy off market materials from the internet. Those products are not regulated by a professional or guaranteed to be made of quality materials.

Teeth whitening will only whiten natural tooth structure. Porcelain crowns/bridges/implants and plastic/resin fillings will not be whitened with any tooth whitening gel/material.

The natural color of the teeth comes from deep within the tooth. Not on the surface. Surface stains from food, coffee, smoking, etcetera can easily be cleaned with a professional cleaning. After a professional cleaning you will see the natural color of the teeth.

Teeth are composed of 3 basic layers. The nerve on the inside, the enamel on the outside and a cushioning layer in between the enamel and the nerve called the dentin. The enamel on the outside is actually transparent. This means the color of the teeth that you see in the mirror is actually the color of the dentin underneath. The middle layer called dentin has a natural yellow color to it. It is one of the few parts of the tooth that regenerates its-self over a lifetime. Over time it lays down more and more layers of dentin in an effort to protect the nerve from outside forces in the mouth. As it lays down more and more layers the teeth naturally become more yellow. That is why our teeth become more yellow the older we get. It is also why children’s teeth appear to be so white. They have much less dentin.

In order to whiten teeth the gel must be allowed to reach the layer of dentin. When the whitening gel is placed on the teeth it opens the pores of the tooth and allows the gel to reach the layer of dentin underneath. The whitening gel works in the layer of dentin and the teeth appear whiter as a result. The teeth can become sensitive during whitening treatment due to the fact that the pores are open, allowing the tooth to “feel” more. Closing of the pores is an extremely important step in the whitening process. Closing the pores eases dental sensitivity after whitening. It also “seals” the tooth, locking in the desired whitening and not allowing dark stains to re-enter the dentin. Professional whitening by a dental professional ensures that all proper steps are taken to insure beautiful results with minimal sensitivity.

Whitening toothpastes should never be used. They do not whiten the teeth even though their marketing can be deceiving. Whitening toothpastes can remove surface stains from smoking, coffee, tea, etcetera. However they do so by using abrasive silicate beads which actually make micro scratches in the teeth. The silicate beads scrub off the surface stain but in the process make small scratches which actually absorb more stain the next time you ingest something dark. The micro scratches in the teeth can also open the pores and cause sensitivity. They do not reach the under layer of dentin which is where the natural color of the teeth come from.

Whitening results and length of whitening varies by patient. It depends on each persons individual body chemistry, personal habits and rate of dentin deposition. Some people only need to whiten once every five years and some people need to whiten every six months to achieve the same level of whiteness.  You should choose your method of whitening according to your personal needs. Whitening has been safely performed since the 1980’s and does not damage the teeth when performed correctly by a professional.

At home teeth whitening can be achieved two ways.

  1. professional whitening strips can be purchased from a reputable dental hygiene office. They are disposable one time use strips with a professional strength whitening gel infused into them. They are worn for one hour per day for about 10 days or until the desired level of whitening is achieved. The strips must be purchased new each time at an average cost of CHF 350.- / per 10 day treatment.
  2. A mold of the teeth is made and sent to a laboratory to fabricate custom plastic whitening trays. Once the plastic teeth molds come back from the lab the patient comes to the office to check the fit of the custom trays. At that appointment the patient is provided with the trays, professional whitening gel and instructions. The patient then wears the trays at home for one hour per day for 10 days or until they have achieved the desired whitening. The initial cost is more because of the laboratory costs. (Approximately CHF 450.-) however it is more cost effective for someone who must whiten more frequently. Once the patient has the custom trays she/he must only purchase the whitening gel to fill the trays for future whitening. The cost of the gel refills are about CHF 30.- per syringe and 2-3 syringes are needed for 7-10 days of whitening.

    In office whitening-

    - is performed in the dental setting.  After a professional cleaning a higher strength whitening gel is placed on the teeth. The gel works in the layer of dentin to rapidly whiten the teeth. This treatment is ideal for patients who do not have the patience for at home whitening or for people who have an important event coming up and need treatment quickly. The high strength gel should only be applied and monitored by a dental professional. The average cost of in office whitening is CHF 500.-.

    Patients who have very dark teeth or who want the “Hollywood Smile” can combine the in office and at home whitening methods to achieve the whitest result. Not everyone requires a combination of methods and whitening is often achieved by using only one method.

    Sensitivity to cold is the most common side effect of whitening due to the open pores. This usually disappears after the whitening treatment is completed and the pores are closed. Although, sensitivity can linger for a short time after whitening is completed and the pores are closed. Each person is different. However, it usually resolves on it’s own quickly following treatment.

    All whitening treatments should be followed up with a treatment to close the pores at the end of whitening.

    A professional cleaning should be performed in combination with and prior to any whitening treatment. This removes any biological materials that would interfere with the absorption of the whitening gel. This allows for the best and brightest results. In this practice whitening will only be performed following a professional cleaning.
