Some foods that can cause toothaches include;

1)Acidic foods:
These foods can erode tooth enamel, causing sensitivity and pain. Examples include citrus fruits, tomatoes, tomato juice, vinegar, and sauerkraut.

2)Sugary foods:
Consuming too much sugar can damage oral health.

3)Hard candies and ice:
Crunching on these hard substances can wear down tooth enamel and expose the dentin layer.

4)Hot and cold beverages:
Sudden temperature changes can cause the enamel to expand and contract, leading to cracks and chips.

5)Starchy foods:
These foods can stick to teeth and lead to plaque build-up and tooth decay.

6)Nuts:
Nuts can contain added sugar, especially when roasted or sweet chili varieties.

7)Dried fruit:
Many dried fruits, like raisins, figs, dates, and prunes, are sticky and can cling to teeth.

To prevent toothaches, you can;
a)Brush your teeth with fluoride toothpaste twice a day.
b)Cut down on sugary foods and drinks.
c)Have regular dental checkups.

If you have a toothache that lasts more than a couple of days, you should consult a dentist.
