Uncomfortable sensation in teeth is commonly experienced as sensitivity, tingling, mild pain, or discomfort while eating, drinking or continuously all the time or even breathing cold air with mouth. It may be temporary or persistent depending on the cause. It usually indicates irritation of the tooth nerves or enamel damage. If ignored, it can lead to bigger dental issues. Early care and proper hygiene can help manage and prevent it.
