Biological dentists make an effort to operate their practices with non-toxic methods and supplies. They also seek to cleanse the body and mouth through a more herbal & nutritional aproach, particularly when exposed from any past toxins that may have been introduced from past dental procedures.

The idea is to resolve some of the problems that could be troubling the patients health by assisting the body's detoxification processes. The goal of biological dentists is to aid the body's inherent capacity for self-healing.

The four most significant sources of potential toxin exposure can come from: lesions within the jaw bone, metal fillings, fluoride, and root canals.

1. What are Lesions within the jaw bone?                                                                                 Lesions within the jaw bone are a major problem that biological dentists hope to address. These tiny holes in the jaw bone are typically the result of a previous tooth extraction that wasn't done correctly, or didn't heal well, or both. They are frequently discovered where wisdom teeth have been extracted. These holes can become filled with fatty cells, bacteria, fungi and infections. They might cause an infection, which would damage the nearby bone. Biological dentists strive to restore and clean the area by getting rid of the germs, dead cells, and other toxins.
2. Fluoride toxins
   Many dentists have long relied on fluoride treatments and rinses. However, a lot of biological dentists do not like the use of fluoride, due to the fact that fluoride is neither a mineral found in teeth nor a nutrient that may in any way aid in body function.
3. Toxic fillings
   You know, those "silver" metal fillings. They contain only a very small amount of silver, if any at all. They may also be harmful as about half of the mercury used to make metal fillings is coupled with copper, tin, and that trace amount of silver. Mercury is a heavy metal that can harm the body in various ways, particularly the brain. Because of this, biological dentists not only avoid using metal fillings, but prefer to see them removed from patients mouths. Therefore, one of the primary goals of biological dentistry is the removal and replacement of metal fillings. 
4. Root Canal Extractions
   A root canal is a procedure used to prevent the extraction of a damaged or unhealthy tooth. Conventional dentistry reach the tooth's root many layers deep inside your tooth, below the enamel and dentin, hence the term "root canal." The pulp is removed, and the space in the root is filled. The Mayo Clinic and a well-known dentist originally warned about the risks of root canals as early as 1910, these are still often performed more than a century later. Biological dentists however will not execute them and will often suggest different and nontoxic options.
