Reasons a dentist keeps the tooth

Incineration

A dentist usually places an extracted tooth into a sealed bio-medical bag because it retains the patient's oral tissue and blood, which are potentially infectious materials. Bio-medical waste services remove the bags from dental offices and bring them to facilities to incinerate their contents.

Recycling

If a general dentist pulls a tooth with a filling containing metal, it is necessary to send it to a recycling facility before incineration. Burning a tooth before removing the filling poses a risk of contaminating the air with mercury found in the metal. The metal can be repurposed after it is removed.

Training

Sometimes, dentists send extracted teeth to universities and other institutions where dental students and colleagues receive training. Extracted teeth can help students studying dental diseases and procedures because they present real case studies and practice models.

Research

A general dentist may want to attend seminars and take workshops to learn about new and updated techniques for patient services. By sending extracted teeth to dental laboratories and research facilities, a dentist can help ensure an adequate supply of models to test the efficacy of new procedures before they are recommended and taught.

Reasons a patient keeps the tooth

Patients may want to keep extracted teeth for various reasons. Before releasing a tooth to a patient, a dentist must thoroughly clean it to remove traces of bacteria and tissue.

Sale

Some individuals who have extracted teeth with metal fillings or gold crowns may wish to deliver them to scrap metal collectors who reuse the material. These services will reimburse individuals according to the amount of retrievable metal. Teeth containing gold crowns are particularly desirable.

Sentiment

There are many reasons why patients have sentimental attachments to extracted teeth. Although this mostly occurs with baby teeth, adults may occasionally attach a particular meaning to a tooth, making it a desirable memento.

Bragging rights

Some patients are intrigued by the removal of teeth from their mouths and want to show them to others. Impacted wisdom teeth are usually large, creating a sense of astonishment that some people feel compelled to share.

Projects

A few patients get creative with extracted teeth, using them as display objects, jewelry, or incorporating them into art projects. Although this is not an appealing route for most persons, it does happen. A general dentist must take great care to sanitize the tooth and instruct the patient about its proper handling before releasing it.
