Root canals involve cleaning out the decay in your tooth's core. As you well know, cavities can worsen over time if you fail to address them. You'll find the bacteria eating away the enamel until it gets to the dental pulp and root as well. 

Once the cavities reach these sensitive areas, you may not handle the sensitivity, pain, and discomfort well. If it gets to that, you might require a root canal. But how can you tell whether a root canal procedure is necessary? Well, be on the lookout for these telltale signs.

Persistent Toothache

If your tooth is badly decayed, you'll always be in pain. Of course, you can take painkillers to alleviate the pain, but the pain always comes back. Sometimes the painkillers won't even work, and you should see a dentist when it gets to that. 

While at the dentist's office, describe how the pain manifests itself. Does it hit you like a wave? Does it get worse when you lay down? Answering these questions will help the dentist determine if a root canal procedure is necessary.

Increased Sensitivity

Increased sensitivity around one tooth is a thing you shouldn't ignore. You can easily tell that your tooth has a problem if it feels sensitive when drinking cold or hot fluids. This sensitivity can cause sharp pain whenever the tooth comes into contact with hot or cold drinks. If the sensitivity persists or becomes worse, you might require a root canal to fix it. Without this procedure, you'll have a hard time eating or drinking.

Swollen Gums

Are your gums swelling without any reason? Well, there is a likelihood you have a tooth infection that needs to be addressed. While brushing or flossing too hard can result in swollen gums, the inflammation will disappear within a few days. 

However, if the swelling results from an infection, it's less likely to disappear. Besides, the gums will be tender to the touch. If the swollen gums prove to be a problem, your dentist might recommend a root canal.

Tooth Discoloration

In most cases, your teeth will get stained because of smoking, drinking coffee, and other beverages. Surprisingly, your tooth can also become discolored because of nerve damage. A dead or dying tooth will change its color from white to yellow, black, gray, or light brown. So, if you notice any discoloration on one of your teeth, you should have a dentist conduct a root canal procedure immediately. 

Other telltale signs include:

• Dental abscess
• Gum pain
• Pain while eating
• Chipped or cracked tooth
• Deep decay
