Tooth sensitivity is a common concern that often presents as discomfort during brushing. In Santa Monica, patients frequently describe a sharp or transient pain when using a toothbrush or when exposed to cold water.
The underlying mechanism usually involves exposed dentin. When enamel is worn down or when gingival recession occurs, the dentinal tubules become more accessible to external stimuli. This can make even routine brushing feel uncomfortable.
We tend to see several contributing factors. Aggressive brushing technique is one of the most common. Patients who use hard bristle brushes or apply excessive pressure may inadvertently cause enamel abrasion and gum recession.
Dietary habits also play a role. Acidic foods and beverages can contribute to enamel erosion over time. Additionally, conditions such as bruxism can accelerate wear, further increasing sensitivity.
From a management standpoint, the first step is modifying technique. Switching to a soft bristle toothbrush and using gentle, controlled motions can significantly reduce discomfort. Desensitizing toothpaste can also help by blocking the transmission of stimuli through the dentinal tubules.
In cases where recession is more advanced, in-office treatments such as fluoride varnishes or bonding agents may be indicated. These approaches help protect exposed areas and reduce sensitivity.
Persistent sensitivity should always be evaluated more closely. While many cases are related to dentin exposure, we also need to rule out caries, cracked teeth, or failing restorations.
Our Santa Monica dentist encourages patients to address sensitivity early, which allows us to intervene before the issue progresses. With proper diagnosis and management, most patients can return to comfortable, effective brushing habits.
