Biological vs. conventional dentistry: what really sets them apart?

It is not just "mercury-free dentistry"

If you have found your way here, you have probably heard about biological dentistry and are wondering how it actually differs from a conventional dental practice. The short answer is that it is not simply about avoiding one toxic material -- it is a fundamentally different way of understanding the relationship between your mouth and your overall health.

Let us go through it point by point.

Philosophy: the tooth vs. the patient

Conventional dentistry focuses on the tooth as an isolated unit: there is a cavity, it gets filled; there is an infection, a root canal is performed; a tooth is missing, an implant is placed. The goal is to solve the local problem as efficiently as possible.

Biological dentistry starts from a different premise: the mouth is part of the whole body. A dental problem can have systemic repercussions, and a systemic disease can have its origin in the mouth. Treatment does not end when the tooth stops hurting -- the aim is to ensure that the treatment itself does not create a new toxic or immunological burden for the patient.

Materials: verified biocompatibility

In conventional dentistry, materials are chosen for clinical efficacy and cost. Mercury amalgam fillings, titanium alloys containing vanadium and aluminium, BPA-containing composites, and metal-ceramic crowns are all commonly used. If a material fulfils its mechanical function, it is considered suitable.

In biological dentistry, verified biocompatibility is required in addition to clinical efficacy. This means ceramic materials (zirconia) instead of metals, BPA-free composites, and the use of tests such as the MELISA Test to verify that the chosen material will not trigger an immune reaction in that specific patient.

Diagnosis: beyond the X-ray

A conventional practice diagnoses primarily through visual examination and radiography. If no pathology is visible on the X-ray, the area is generally considered problem-free.

Biological dentistry incorporates additional investigations: material biocompatibility analysis, assessment of interference fields (chronic silent infection foci), evaluation of the relationship between oral pathology and systemic symptoms, and coordination with other healthcare professionals when needed.

Treating infections: preserve vs. restore health

When faced with a tooth with infected pulp, conventional dentistry will perform a root canal to preserve the tooth. It is a predictable treatment with good short-term success rates.

Biological dentistry can also perform root canals when it is the best option, but evaluates each case with additional variables: could the root-canal-treated tooth become a chronic infection focus? Does the patient have autoimmune or systemic conditions that could be aggravated? If extraction is the better option, it is carried out using a biological surgery protocol that includes cavitational curettage, ozone therapy, and subsequent rehabilitation with ceramic materials.

Prevention: hygiene vs. holistic approach

Conventional prevention is based on oral hygiene, fluoridation, and regular check-ups. It is effective for preventing cavities and periodontal disease.

Biological prevention includes the above (with fluoridation replaced by alternatives) and adds a nutritional focus, identification of toxic habits, evaluation of the impact of previous dental materials, and collaboration with other specialists to address the systemic causes of oral pathology.

Which is better?

This is not about one being "good" and the other "bad." Conventional dentistry solves dental problems effectively and affordably. Biological dentistry offers a broader approach that can be especially valuable for patients with material sensitivities, autoimmune conditions, chronic systemic symptoms, or simply those who want dental care that considers the impact of every treatment on overall health.

At Bio Salud Dental, we have been practising biological dentistry for over 30 years. It is not a trend -- it is a conviction grounded in clinical experience and the accumulated evidence on the relationship between oral health and systemic health.
