Is your tooth throbbing with pain, or are you constantly reaching for the ice pack after eating something cold? These might not just be minor annoyances; they could be signs that your tooth is in trouble and in need of serious care. If left untreated, these issues can escalate into a serious infection, and before you know it, a root canal might be your best option to save your tooth. But how do you know if you need one?
In this blog, we’re going to walk you through the 5 clear signs you might need a root canal, helping you spot the early warning signs before the problem gets worse.
1. Persistent Tooth Pain
Chronic tooth pain is one of the most obvious signs that it’s time for a root canal. If it hurts no matter what you do, and is even more painful when something is placed on the tooth (like during chewing), it usually means the tooth infection is deep enough to reach the tooth’s inner pulp.
The pain may even come and go. You may think it is gone, and then it is back stronger than ever. If the pain is paired with swelling or a fever, the infection may have progressed. This makes the root canal more necessary. Â
How do you know when to get a root canal? If pain relief is a routine activity of yours, it’s time to go to the dentist. This is a sure sign that you are headed towards a more complicated dental procedure if the pain is ignorable and the damage is more severe.
2. Sensitivity to Hot and Cold
Tooth sensitivity is a common issue, but when it lingers long after you’ve eaten or drunk something hot or cold, it could be one of the root canal signs. Tooth sensitivity root canal can manifest as sharp, intense pain triggered by something as simple as a sip of hot tea or an ice cream cone.
If the pain lasts more than a few seconds or doesn’t go away after the temperature stimulus is removed, it could indicate that the nerve inside the tooth is infected. This is a key root canal infection symptom, suggesting that the tooth pulp (which houses nerves and blood vessels) is under attack by bacteria.
If you’re experiencing this kind of sensitivity, don’t just brush it off. The longer you wait, the worse the infection can get.
3. Swollen or Tender Gums
Your tooth may be infected if the gums surrounding the tooth are swollen, sensitive, and appear slightly red. Out of all the signs that indicate an infected tooth, this is the most common. Your body is always trying to keep you notified when there is a problem, and it is doing it right now.
In some situations, there might be a small pimple-like bump on the gums that may even drain a pus-like fluid. This indication of infection becomes especially severe when there is also pain and fever. This may require a root canal to save the infected tooth from spreading the infection to even more parts of your mouth.
These signs should not be ignored. Infection can spread, and if the tooth structure is compromised, you may require a root canal.
4. Tooth Discoloration
Have you noticed that a particular tooth is turning a darker shade compared to the rest? While this could be a result of staining, it might also be a sign of tooth decay root canal. A darkened tooth can occur when the pulp inside the tooth becomes infected and begins to die, leading to changes in the color of the enamel.
This discoloration isn’t something that will simply go away on its own. If left untreated, the infection could worsen, leading to more severe issues like tooth loss. A root canal infection is often the best solution to prevent further damage and keep the tooth in place.
If you’re concerned about the color of your tooth, especially if you’ve also been experiencing other symptoms like pain or swelling, it’s best to consult your dentist right away.
5. A Recurring Pimple on the Gums
Don’t ignore recurring gum pimples or abscesses when you have reason to believe you might need a root canal. A pimple on your gum may mean that there is an infected root canal, causing a pocket of infected pus to build up. A pus bump may form on your gum as pressure from the infection causes the pus pocket to drain.
A pimple on your gum may seem like a minor issue, but it actually indicates an infection that is much deeper in the tooth. Leaving an infection this severe unaddressed can spread to other areas of your mouth, or even worse, your bloodstream. If left untreated, the infection can spread and cause serious health complications.
What Happens During a Root Canal?
If you’re showing any of these root canal signs, your dentist will likely recommend the procedure. During a root canal, the dentist removes the infected pulp, cleans the inside of the tooth, and fills it with a special material to seal it. The tooth is then restored with a crown to ensure it functions like a natural tooth.
While the idea of a root canal might sound intimidating, the procedure itself is often no more painful than getting a routine filling, thanks to local anesthesia. Most people report feeling much better after the procedure, with pain significantly reduced or completely gone.
When Should You See a Dentist?
If you’ve been experiencing any of the symptoms mentioned above—persistent pain, tooth sensitivity, gum tenderness, discoloration, or recurring pimples—it’s time to schedule an appointment with your dentist. The earlier you address these tooth infection signs, the better the chances of saving the tooth and preventing further complications.
Ignoring the root canal infection symptoms can lead to more severe issues like tooth loss or the spread of infection, so it’s important to take action early. Your dentist will be able to assess your condition and recommend the best course of action.
