is tooth sensitivity normal

Tooth sensitivity is pretty common, you’re not alone in experiencing it. It happens when the softer parts of your teeth (like dentin) are exposed, usually due to erosion or receding gums. Regular activities like eating or drinking cold, hot, sweet, or acidic foods and drinks can trigger that sharp pain, as can cold air, so you’re noticing those triggers makes sense. A lot of people deal with this, but it’s important to understand what’s causing it for you specifically, in case it’s tied to a more serious issue. You took a solid first step by trying toothpaste made for sensitive teeth, but since you’re not seeing improvement, it’s a good idea to have a dentist check if there’s an underlying cause. Factors like tooth decay, worn fillings, or gum disease could be contributing, and it’s best to address these sooner rather than later. You asked about certain foods - yes, acidic foods and drinks can worsen the sensitivity, and you might want to cut back on those to see if it helps. Avoid brushing immediately after consuming acidic items, as the enamel can be more prone to damage right then. In terms of whether to see a dentist, given your symptoms have persisted, I’d recommend it. A professional can identify if there’s something specific needing treatment, or if alternate solutions might help. They can also guide you on techniques like proper brushing, which might alleviate the symptoms over time. Waiting it out could lead to additional wear or damage if there’s an underlying issue, so tackling it now is usually the best bet. Don’t feel like you’re overreacting; you’re taking sensible steps to protect your dental health.
