Signs that Indicate an Underlying Dental Cavity

Dental cavities are a common problem that affects people of all ages. These cavities are caused by the accumulation of plaque and bacteria on the teeth, which can lead to decay and erosion of the tooth enamel.

While cavities can often be treated with fillings, it's important to catch them early before they cause more significant damage. Let’s look at some of the signs that indicate an underlying dental cavity.


One of the most common signs of a dental cavity is a toothache. It can be a sharp or dull pain that occurs when you bite down or eat something sweet, hot, or cold.

The pain may be constant or intermittent, and it may get worse over time. If you're experiencing tooth pain, seeing your dentist as soon as possible is important.


Another common sign of a dental cavity is sensitivity in your teeth. Tooth sensitivity can occur when you eat or drink something hot, cold, or sweet. You may also experience sensitivity when you brush or floss your teeth. Sensitivity can be a sign that the enamel on your teeth has been weakened by decay and erosion.

Visible Holes or Pits

If you notice a hole or pit in your tooth, it's a sign that you may have a dental cavity. These holes can be visible to the naked eye or may be discovered during a dental exam. If you notice a hole or pit in your tooth, it's important to see your dentist immediately to prevent further damage.

Bad Breath

If you have bad breath that won't go away, it may be a sign of an underlying dental cavity. When bacteria and plaque accumulate on the teeth, they can produce a foul odor. If you have persistent bad breath, you should see your dentist to rule out any dental issues.


If you notice discoloration on your teeth, it may be a sign of a dental cavity. The discoloration may be white, brown, or black, and it may be visible on the tooth's surface or underneath the enamel. Discoloration can signify that the tooth has started to decay and may need to be treated by a dentist.

Swelling or Pus

If you notice swelling around your teeth, gums, or jawline, it could be a sign of a dental cavity that has progressed to an abscess. An abscess is a pocket of pus that forms when bacteria infect the tooth or gum.

You need to seek treatment for an abscessed tooth as soon as possible, as it can lead to serious complications if left untreated. The swelling may also be accompanied by pain, redness, and tenderness.

Sensitivity to Pressure

If you experience pain or sensitivity when biting down or applying pressure on a specific tooth, it could indicate the presence of a cavity. The pressure can cause the decay to spread further, resulting in more extensive damage to the tooth.

Visit a dentist as soon as possible to determine the cause of the sensitivity and prevent further damage.
