Do you experience tooth sensitivity to hot or cold that resolves quickly, so you forget about it? Or have you noticed discoloration in a tooth? Did you know that these may be signs of tooth decay? 

The good news is that a dental filling can typically treat a cavity if we spot it early. Here are some early signs of tooth decay in Garland, TX, that may also be signs you need a dental filling.

Understanding Tooth Decay

To help reduce tooth decay, it's important to understand how it works. 

Sugar is the fuel for the bacteria in your mouth that cause tooth decay. When your sugar intake is high, these bacteria are more likely to harm your teeth. The bacteria take in the sugar and then produce acid as a byproduct. The acid strips away tooth enamel and promotes decay and cavities. 

When we spot it early, tooth decay treatment in Garland is often as simple as a dental filling. Dr. Jung is your trusted dentist for cavities in Garland.
