Understanding Tooth Sensitivity
Tooth sensitivity is one of the most common complaints dental hygienists hear. It typically presents as a sharp, brief pain triggered by hot or cold foods and drinks, sweet or acidic foods, cold air, or even brushing. The discomfort occurs when the inner layer of the tooth, called dentine, becomes exposed due to gum recession, enamel erosion, or worn enamel. Exposed dentine contains tiny channels that lead directly to the nerve, making the tooth more reactive to changes in temperature or pressure.
Professional Desensitizing at A Cleaner Smile
Our hygienists use professional-grade desensitizing agents applied directly to the affected teeth to block the channels in exposed dentine and reduce the nerve’s reaction to external stimuli. This treatment is significantly more effective than over-the-counter sensitivity toothpaste because it delivers a higher concentration of active ingredients directly where they are needed. Desensitizing treatment is typically performed at the end of your hygiene appointment and takes only a few minutes.
When Is Desensitizing Recommended?
If you have been avoiding hot or cold foods because of tooth pain, or if brushing near the gumline causes regular discomfort, desensitizing treatment is worth discussing with your hygienist. It is also commonly recommended following scaling appointments where gum tissue may be temporarily more sensitive. For patients who experience sensitivity across multiple teeth, your hygienist may also recommend reviewing your diet and brushing technique, as acidic foods and aggressive brushing are two of the most common causes of enamel wear and sensitivity.
