In case you have sensitive teeth plan a visit to your dental lab. Pain in your teeth drinking cold drinks or when eating hot meals might be indicative of serious dental problems, you could have a hole, nerve inflammation, or nerve irritation. These are dental problems you don't wish to ignore.
Wash after eating sticky foods. Foods like caramel and taffy can stick to the top of the teeth. This can be very destructive to your teeth. Ensure that you thoroughly wash away the residue when possible. Additionally, you may want to reduce your usage of these types of foods.
