what can it mean if your tooth hurts to cold things
Tooth sensitivity is caused when the outside of teeth, or the hard enamel, wears down or gums recede and the tiny tubes in the tooth dentin become exposed. Each of those tiny tubes contains a lot of nerve endings, and when theyâre left open, it can hurt when you put hot or cold things in your mouth. A lot. âWhat causes the enamel to wear away?â Most often, tooth enamel wears away due to eating of too many acidic foods or drinks, excessive acid reflux, brushing too hard, or by clenching or grinding.
