### Common Symptoms of Cavities and Prevention Tips Cavities, also known as tooth decay, can cause a variety of symptoms. Here are some of the most common signs that you might have a cavity: 1. **Sensitivity to Hot, Cold, or Sweet Foods**: If you feel a lingering sensitivity after consuming hot, cold, or sweet foods, it could be a sign of a cavity. This happens because the enamel on your tooth is wearing away, exposing the dentin underneath. 2. **Toothache**: An ongoing ache in one or more of your teeth can indicate a cavity. This pain might come on suddenly or be triggered by something you eat. 3. **Discoloration**: Stains on your tooth may first appear as white spots. As the decay progresses, these stains can turn brown, black, or white. 4. **Visible Holes or Pits**: If you notice a hole or pit in your tooth, it's a clear sign of tooth decay. Some holes might not be visible but can still cause pain or sensitivity. ### Prevention Tips Preventing cavities is crucial for maintaining good oral health. Here are some tips to help you avoid tooth decay: 1. **Brush and Floss Regularly**: Brushing your teeth twice a day and flossing daily can help remove plaque, which is a sticky film of bacteria that forms on your teeth. 2. **Use Fluoride Toothpaste**: Fluoride helps to strengthen tooth enamel and can prevent cavities. Make sure to use a toothpaste that contains fluoride. 3. **Regular Dental Check-ups**: Visiting your dentist every six months for a check-up and cleaning can help catch cavities early and prevent them from getting worse. 4. **Limit Sugary Foods and Drinks**: Sugary foods and drinks can contribute to tooth decay. Try to limit your intake of sweets and opt for healthier snacks. 5. **Drink Plenty of Water**: Drinking water helps to wash away food particles and bacteria from your mouth, reducing the risk of cavities. If you notice any signs of a cavity, such as sensitivity, pain, discoloration, or holes in your teeth, make an appointment with your dentist as soon as possible. Early treatment can prevent more serious dental issues down the line.
