How Do I Know If I Need a Root Canal?
If you are feeling sharp, lingering pain in your tooth, it could mean the nerve is affected and a root canal is necessary. However, if the discomfort is mild and associated with a cavity, a filling may be sufficient.
This blog will guide you through the differences between root canals and fillings, explain how dentists decide between them, and what you should expect if you need one.
What Goes On in Your Tooth?
Your tooth is composed of three layers: the pulp, which houses blood vessels and nerves, the softer dentin below, and the hard outer enamel. When decay (a cavity) or a crack in the tooth reaches the dentin, it causes mild pain or sensitivity. This usually calls for a filling.
However, if the damage goes deeper into the pulp, bacteria can infect it, leading to severe pain, swelling, and the need for a root canal.
Root Canal vs. Filling: How to Tell?
A dentist determines whether you need a root canal or a filling based on how deep the decay has reached and whether the pulp is infected.
When a Filling is Enough
If the decay is limited to the enamel or dentin, a filling will clean out the cavity and seal the tooth to prevent further damage.
The Need for a Root Canal
If you have mild discomfort when eating sweets, you may just need a filling. But if you wake up with a throbbing toothache that doesn’t stop, it’s likely the pulp is infected, and a root canal is required.
Root Canal or Crown or Both?
Many patients ask: “Do I need a crown or a root canal?” When decay or cracks weaken a tooth, a crown covers and shields it. But putting a crown on won’t fix the issue if the pulp is infected.
If a house has a leaky roof, you can’t just put a new roof on top of the damage. You have to fix the problem underneath first. That’s what a root canal does before a crown is placed.
Is Root Canal Treatment Painful?
This is a common concern, but modern root canal treatments are much less painful than people think. Most patients say that the pain leading up to the procedure (from the infection) is worse than the actual root canal.
Local anesthesia makes the procedure virtually pain-free, and most people feel only mild soreness afterward, similar to what you might feel after a filling.
Root Canal Treatment Side Effects
Like any dental procedure, root canal therapy is generally safe and effective, but it can have some short-term side effects.
1. Mild Discomfort and Soreness
Following a root canal, it’s normal to feel mild pain or soreness around the treated tooth and surrounding gum tissue.
This discomfort usually occurs because the area was worked on and the tissues are healing, and the soreness may feel similar to what you get after a filling or tooth extraction.
2. Slight Swelling and Tenderness
Swelling is your body’s natural response to healing and usually occurs around the gum near the treated tooth. You might also notice some tenderness when chewing or touching the area.
The swelling should be minimal and go away within a few days.
3. Transient Sensitivity of the Teeth
For a brief period following the surgery, the treated tooth may occasionally feel sensitive to hot or cold conditions. This sensitivity happens because the surrounding tissues are still healing.
Sensitivity usually decreases gradually and disappears within a week or two.
To prevent discomfort, stay away from extremely hot or cold meals and beverages at this time.
4. Potential Tingling or Numbness
Because local anesthesia is used during the root canal, you may experience numbness or tingling in your lip, tongue, or cheek that can last for a few hours after treatment. This is typical and should go away entirely.
5. Rare Side Effects: Persistent Pain or Infection
Rarely, the infection could recur, or the tooth might not heal correctly. This can cause:
- Persistent or worsening pain
- Swelling that doesn’t go away
- Development of an abscess (a pus-filled infection)
How Long Does a Root Canal Take?
The majority of root canal procedures can be completed in one or two visits, depending on the number of roots and the complexity of the infection. Each visit lasts between sixty and ninety minutes on average.
When Must You Take Action? To what extent is a root canal urgent?
Untreated root canal infections can result in abscesses, spread to the jawbone, and can create major health problems if germs get into the blood.
Don’t delay if you experience ongoing discomfort, swelling, or a lump on your gums close to the tooth.
Root Canal Before and After
Before a root canal, you might experience severe tooth pain, swelling, and an unpleasant taste from a possible abscess.
After the treatment, the pain stops, the tooth is cleaned and sealed, and a crown restores its function and appearance.

How urgent is a root canal infection?
Root canal infections can spread quickly and become serious. Seek dental care as soon as you notice severe tooth pain or swelling.
Will a root canal prolong the tooth’s life?
Yes, a tooth can last a lifetime after a successful root canal, especially if restored with a crown and good oral hygiene.
