Dental hypersensitivity affects 45 million adults in the United States and 10 million are chronically affected with sensitive teeth. Tooth sensitivity is any degree of tooth discomfort after eating cold or hot foods or liquids or even breathing cold air. This problem often happens when gums recede and/or cementum is not presence. The gum tissue acts like a protective blanket to cover the roots of the teeth. As the gums recede the underlying tooth roots are exposed. They are not covered by hard enamel. Thousands of tiny dentinal tubules or channels leading to the tooth’s never center or pulp of the tooth are than exposed. These tubules allow more stimuli like heat, cold or pressure to reach the nerve in the tooth and cause pain.
