Cracked Fractured and Worn Teeth:

With any problem in life, ideally we want to solve the cause of the problem, not just treat the result or outcome. This is true for dentistry as well. As a dentist I have much success treating my Charlotte NC area patients because I always try to solve the cause of the problem, not just the symptom. Naturally when a tooth breaks we need to fix it with a filling or some other dental treatment. But we need to look deeper and figure out why it broke in the first place. Often times we can trays the problem back to an unbalanced bite. The following pictures reveal damaged teeth. The damage in all these cases was an unbalanced bite. All this damage started long before the teeth actually broke or before the fracture lines became obvious. They all started out as microscopic fractures caused by an unbalanced bite which then propagated to more obvious fractures and cracks. 

The following are worn teeth. Excessively worn teeth are unattractive and make a person seem older as well. More importantly, worn teeth loss the outer enamel layer which exposes the softer more vulnerable dentin. Dentin is more vulnerable to damage than enamel.

Wear:

In materials science, wear is erosion or sideways displacement of material from its "derivative" and original position on a solid surface performed by the action of another surface.

Wear is related to interactions between surfaces and more specifically the removal and deformation of material on a surface as a result of mechanical action of the opposite surface. The need for relative motion between two surfaces and initial mechanical contact between asperities is an important distinction between mechanical wear compared to other processes with similar outcomes.

The definition of wear may include loss of dimension from plastic deformation if it is originated at the interface between two sliding surfaces.

However, plastic deformation such as yield stress is excluded from the wear definition if it doesn't incorporates a relative sliding motion and contact against another surface despite the possibility for material removal, because it then lacks the relative sliding action of another surface.

Impact wear is in reality a short sliding motion where two solid bodies interact at an exceptional short time interval. Previously due to the fast execution, the contact found in impact wear was referred to as an impulse contact by the nomenclature. Impulse can be described as a mathematical model of a synthesised average on the energy transport between two travelling solids in opposite converging contact. Cavitation wear is a form of wear where the erosive medium or counter-body is a fluid.

Corrosion may be included in wear phenomenons, but the damage is amplified and performed by chemical reactions rather than mechanical action.

Wear can also be defined as a process where interaction between two surfaces or bounding faces of solids within the working environment results in dimensional loss of one solid, with or without any actual decoupling and loss of material. Aspects of the working environment which affect wear include loads and features such as unidirectional sliding, reciprocating, rolling, and impact loads, speed, temperature, but also different types of counter-bodies such as solid, liquid or gas and type of contact ranging between single phase or multiphase, in which the last multiphase may combine liquid with solid particles and gas bubbles.

Fracture:

A fracture is the (local) separation of an object or material into two, or more, pieces under the action of stress.

The word fracture is often applied to bones of living creatures (that is, a bone fracture), or to crystals or crystalline materials, such as gemstones or metal. Sometimes, in crystalline materials, individual crystals fracture without the body actually separating into two or more pieces. Depending on the substance which is fractured, a fracture reduces strength (most substances) or inhibits transmission of light (optical crystals).

Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture.

In modern materials science, fracture mechanics is an important tool in improving the mechanical performance of materials and components. It applies the physics of stress and strain, in particular the theories of elasticity and plasticity, to the microscopic crystallographic defects found in real materials in order to predict the macroscopic mechanical failure of bodies. Fractography is widely used with fracture mechanics to understand the causes of failures and also verify the theoretical failure predictions with real life failures.

Stress:

In continuum mechanics, stress is a measure of the internal forces acting within a deformable body. Quantitatively, it is a measure of the average force per unit area of a surface within the body on which internal forces act. These internal forces are a reaction to external forces applied on the body. Because the loaded deformable body is assumed to behave as a continuum, these internal forces are distributed continuously within the volume of the material body, and result in deformation of the body's shape. Beyond certain limits of material strength, this can lead to a permanent shape change or structural failure.

Deformation:

Deformation in continuum mechanics is the transformation of a body from a reference configuration to a current configuration.] A configuration is a set containing the positions of all particles of the body.

Strain:

A strain is a normalized measure of deformation representing the displacement between particles in the body relative to a reference length.
