Cavities, or tooth decay, are common dental issues that can lead to more serious problems if ignored. Knowing the early signs of cavities can help you address them before they worsen. Here’s how you can tell if you might have a cavity and the steps you should take.
Early Sensitivity: Pay Attention to Discomfort
One of the first signs of a cavity is increased sensitivity in your teeth, especially to hot, cold, or sweet foods and drinks. This happens when the enamel, the protective layer of your teeth, starts to wear down, exposing the sensitive inner layers.
Persistent Toothache
A persistent toothache, whether it’s a dull ache or sharp pain, is a clear indicator that something is wrong. Don’t ignore toothaches that come and go without an obvious cause—they could be signs of significant decay that need attention.
Visible Changes
Inspect your teeth regularly for visible signs of cavities, such as small holes or pits. These are common in hard-to-reach areas like between your teeth or on the chewing surfaces. Also, watch for sudden discoloration, like white, brown, or black spots, which can indicate decay.
Bad Breath and Unpleasant Taste
Pain During Chewing
Pain or discomfort when chewing or biting may suggest that a cavity has progressed deeper into your tooth, affecting the nerve. This type of pain typically indicates more advanced decay which may require a root canal to repair.
Gum Symptoms
While swollen or bleeding gums are more commonly associated with gum disease, they can also signal cavities. Decay near the gum line is most likely to affect gum health. If you notice these symptoms along with other signs of decay, it’s time to see your dentist.
What To Do Next
If you suspect you have a cavity, take action promptly to prevent further damage:
- Make a Dental Appointment: Schedule a visit with your dentist for an examination and treatment.
- Improve Your Oral Care: Brush twice daily with fluoride toothpaste, floss regularly, and consider using mouthwash to reduce plaque.
- Watch Your Diet: Limit sugary and acidic foods and drinks that can contribute to tooth decay.
- Regular Check-ups: Maintain regular dental check-ups to catch cavities early and keep your teeth healthy.
