6 Obvious Signs That You May Need a Root Canal

Root canals are usually needed when the nerve of a tooth becomes infected. This can happen because of decay, a crack in the tooth, or an injury. The infection can cause severe pain, and if it’s not treated, it can spread to other parts of the body. There are several signs that you may need a root canal, and you should be aware of them. Here are some of them.

Persistent Pain

If the pain in your tooth is constant and you can’t get it to go away, this is a sign that it’s time to make an appointment with a dentist. Some people try to ignore the pain, hoping that it will eventually go away. However, this isn’t a good idea because the infection will only get worse.

Swollen or Tender Gums 

Swollen and tender gums are a clear sign that you have an infection. If the pain you’re feeling is coming from inside your mouth, it’s time to see a dentist. Swollen gums can also indicate an infection in other parts of your body, such as your nose or throat. Tender skin around the gum line is another sign that you have an infection.

Sensitivity to Hot or Cold

If you’re feeling pain or sensitivity when you bite down or eat hot foods and drinks, it’s a good idea to visit a dentist to see if you might need a root canal. Sometimes cold sensitivity can mean different things, but if you have a tooth that doesn’t respond well to heat, that’s usually a sign that something is wrong.

Tooth Discoloration

Discoloration of your teeth usually means you have a cavity, although it could also be caused by other factors like certain medications, smoking, and certain foods and drinks. If your teeth start to change color, you should see a dentist and get them checked out.

If you notice your tooth is starting to look a little darker than normal, that’s often a sign that you might need a root canal. This is because the nerve inside the tooth can die, which can cause the tooth to discolor.

Pain While Eating

If you notice that your tooth is sensitive when you touch it or when you eat, it’s essential to make an appointment with your dentist right away. This could indicate severe tooth decay or nerve damage, both of which require professional treatment. If the sensitivity persists over time and doesn’t go away when you stop eating, it’s likely that a root canal will be necessary to save the tooth.

Cracked or Chipped Tooth

If you have a cracked or chipped tooth, then it’s not something you should just leave alone and ignore. A damaged tooth can not only cause pain and discomfort, but it can also lead to further damage and even tooth loss. Depending on the severity of the crack or chip, your dentist may be able to fix it with a filling or dental bonding. However, if the damage is more extensive, you may need a root canal or even surgery.


These are just some of the common signs that a root canal may be needed to get rid of all those symptoms. If you are experiencing any of these symptoms, you better schedule a consultation with a dentist right away. A root canal may be necessary to preserve the health of your teeth.
