Signs You Have A Cavity And Need To See Our Houston Dentist

Cavities, also known as tooth decay or dental caries, are actually fairly common. They are places in the tooth that have been permanently damaged. This damage causes your tooth to develop holes in it. Those holes are what we refer to as cavities. Dental caries can develop due to a number of reasons, but there are ways to prevent cavities. However, this dental blog will discuss some signs that indicate you or your child may have cavities. 

Signs You’re Experiencing Tooth Decay

The signs relating to cavities may differ from case to case, simply because they affect patients differently. Some have severe cavities while others have smaller ones that may not seem as evident.


A toothache is one of the clearest, earliest signs that someone has a cavity, especially if the ache is random and sticks around for some time without any known cause. Keep in mind though that toothaches, though a characteristic of a toothache, can also be due to other concerns, such as impacted wisdom teeth, a missing filling, or an infection. It’s best that you contact us immediately so we can see you as soon as possible.


It can be hard to tell the difference between a toothache and tooth sensitivity, but we typically describe a toothache as a sensation that doesn't go away on its own. Tooth sensitivity, on the other hand, usually manifests as a sensation that causes you to twinge or cringe in response due to its strange discomfort. Sensitivity is usually triggered by something and isn’t persistent like a toothache would be. For example, if you have a sensitive tooth, it might cause you to feel discomfort immediately after eating or drinking something too hot or too cold. Eating citrus fruit may also trigger an uncomfortable response, but it will go away shortly after. Although tooth sensitivity could be a good indicator of a cavity, it may also result from gum recession or gingivitis, so we will recommend a closer dental examination with our Houston dentist.

Visible Holes In Your Teeth

The most obvious sign that you or your child has a severe cavity is your tooth exhibiting a clearly visible hole or pit, usually blackish or brownish in color.
