Have you ever been surprised to find out you had a cavity during a dental visit? While cavities on the outer surface of teeth are easy to spot, some can form deep inside, hidden from view. These “hollow” teeth may not show visible signs right away—but your body often sends subtle warnings.

Unexplained Sensitivity or Pain

If your tooth suddenly becomes sensitive to hot or cold foods and drinks, it could be a sign that decay has reached the inner layers of the tooth. This happens when temperature changes affect the exposed nerves inside the cavity.

However, not all sensitivity means there’s decay—some people naturally have sensitive teeth. But if the discomfort appears suddenly or worsens over time, it’s best to have it checked by your dentist. Pain after eating sweet or sour foods can also signal a cavity forming inside your tooth.

Unpleasant Breath or Taste in Your Mouth

A cavity forms when part of your tooth structure starts to decay. That decay can trap food particles and bacteria, leading to bad breath or a persistent unpleasant taste in your mouth. If you notice these symptoms and can’t trace them back to something you ate, you may be dealing with hidden tooth decay.

Be Proactive About Your Dental Health

Even when cavities aren’t visible, they can cause significant damage if left untreated. Regular dental checkups allow your dentist to use X-rays and professional examination tools to detect hidden decay early—before it turns into a painful or costly problem.

By paying attention to early warning signs like sensitivity, bad breath, and sudden discomfort, you can catch tooth decay in its early stages and protect your oral health. Schedule a checkup today and keep your smile healthy from the inside out.
