Adverse Effects of Excessive Tooth-Brushing on Oral Health

Adverse Effects of Excessive Tooth-Brushing on Oral Health
03 August 2023

Maintaining optimal oral hygiene practices is essential for preserving dental health, with regular tooth-brushing being a fundamental component. However, excessive and improper tooth-brushing can have detrimental effects on the oral cavity. This blog aims to elucidate the potential risks associated with over-brushing, substantiated by empirical evidence from academic and medical literature.

Enamel Erosion
Excessive tooth-brushing, characterised by vigorous brushing or use of firm-bristled toothbrushes, is correlated with enamel erosion. The abrasive action of over-brushing compromises the integrity of tooth enamel, rendering teeth more susceptible to caries and heightened sensitivity.

Gum Recession
Aggressive brushing and increased frequency can instigate gingival recession. The application of excessive force to gingival tissues leads to its displacement, thereby exposing the tooth roots and augmenting the risk of dentinal hypersensitivity and periodontal pathologies.

Irritation and Hemorrhage of Gingival Tissue
Excessive tooth-brushing, characterised by forceful brushing or frequent brushing sessions, may incite inflammation and hemorrhage of the gingival tissue. Physiologically healthy gingiva should not exhibit bleeding during routine oral hygiene practices.

Perturbation of Oral Microbiome
The oral cavity harbours a complex ecosystem of microorganisms collectively known as the oral microbiome. Overbrushing has the potential to disrupt the microbial balance, fostering an overgrowth of pathogenic bacteria.

Heightened Risk of Dental Abrasion
Frequent and forceful tooth-brushing contributes to dental abrasion, characterised by the loss of tooth structure due to mechanical friction during brushing. The repetitive scrubbing motion, particularly in conjunction with abrasive toothpaste formulations, culminates in the gradual erosion of tooth surfaces.
While regular tooth-brushing is crucial for maintaining oral health, it is imperative to strike a balance and avoid over-brushing. Vigorous or frequent brushing can lead to enamel erosion, gum recession, gingival irritation and bleeding, disruption of the oral microbiome, and an increased risk of dental abrasion. 
Dental professionals should advocate a standardised oral hygiene regimen that includes gentle brushing techniques with a soft-bristled toothbrush, emphasising the importance of regular dental check-ups for comprehensive monitoring of oral health status.
