Tooth enamel erosion: risk factors and processes of destruction


Regular exposure to acids reduces the hydrogen index of saliva below the critical level, triggering a rapid process of leaching minerals from the dental matrix. Hard fabrics lose their natural shine, thin out, and become covered with matte spots that resist home bleaching.
A non-carious lesion exposes sensitive dentin, causing acute pain when exposed to hot coffee or cold air. The absence of dental intervention leads to pathological erasure of the crowns and changes in bite.
Chemical and mechanical triggers
Regular consumption of carbonated drinks, freshly squeezed citrus juices and sports energy drinks containing orthophosphoric acid is a key factor in demineralization. The internal cause is often gastroenterological pathologies: reflux disease throws aggressive gastric juice into the oral cavity during sleep.
Hard brushes and highly abrasive pastes with an RDA index above 100 scratch softened enamel, accelerating tissue loss.
Aggressive factors of destruction of the surface layer:
- professional work in chemical plants with acid vapors;
- eating disorders accompanied by regular vomiting;
- nocturnal bruxism on the background of thinning of the protective barrier.
Taking iron preparations in the form of syrups and the constant resorption of ascorbic acid also change the acid-base balance not in favor of dental strength.
Symptoms at different stages of demineralization
The initial phase is painless: the crown simply loses its natural gloss, and barely noticeable chalky areas appear on the incisors. The progression of the pathology leads to the formation of smooth cup-shaped depressions on the frontal surface, exposing a yellowish layer of dentin.
The edges of the incisors become transparent and begin to crumble when biting off hard food like apples or nuts.
The clinical picture of a deep lesion includes:
- shooting pains during temperature changes;
- hyperesthesia when touching a toothbrush;
- visible shortening of the height of the clinical crown.
A decrease in the height of the bite overloads the temporomandibular joint, provoking clicks when opening the mouth and chronic pain of tension of the jaw muscles.
Remineralization protocols
Stopping the process begins with adjusting the diet: juices are drunk exclusively through a tube, and after taking acidic food, the mouth is rinsed with a solution of sodium fluoride. The dentist conducts a course of deep fluoridation, sealing microcracks with calcium-phosphate complexes using electrophoresis or individual mouthguards.
If more than a third of the enamel thickness is lost, conservative therapy is powerless, and the defects are covered with light-curing composites or ceramic veneers. Total prosthetics with zirconium dioxide crowns is used in advanced cases to restore the correct anatomy of the jaw and protect the pulp from inflammation.
