Zahn Bleaching

The importance of dental aesthetics for patients has greatly increased in recent years.

The development of simple, fast, and safe bleaching methods has strengthened this trend.

By now, many people recognize that one can make a better impression with well-kept, white teeth, both in their professional and private lives. Even a hearty laugh is only half as nice if your teeth are yellow and unsightly. Over the years, various bleaching methods have been developed. With vital teeth, the most common methods are office and home bleaching.

In-Office Bleaching:

This is done directly at the dentist’s practice. An approx. 38% bleaching gel is used and the procedure takes about an hour.

Home Bleaching:

In this case, a splint is prepared. The patient fills the splint at home with an approx. 20 % bleaching gel and wears it approx. 7-10 days for at least one hour every day or during the night.

In case of dead (root canal treated) teeth in the anterior region that have turned gray, “internal bleaching” can be done. In this case, the old root filling is partially removed, the tooth is filled with bleaching gel and the tooth is closed again. The gel can remain in the tooth for up to three days and thus whiten the tooth from the inside out. This procedure may be repeated as needed. Once the desired result has been achieved, the root canal is rinsed well.

Contraindications to bleaching:

  • Very sensitive teeth
  • Exposed tooth necks
  • Periodontitis
  • Leaking fillings

 

Chances of Success:

Patients are interested in a permanent bleaching result. However, a precise prognosis of the result is hardly possible. In most cases, a good whitening result about 1-2 color shades lighter than the original color can be achieved. In the long term, 63% of patients can count on whitening results lasting two to three years and 42% can count on positive long-term results lasting up to seven years (Leonard 2000). Smoking or frequently drinking coffee, tea, or red wine may negatively influence the result.
