Tooth pain is never something to ignore. While some minor sensitivity may not be a cause for concern, persistent pain, swelling, or discomfort could indicate a serious problem. One of the most common reasons for prolonged tooth pain is an infection deep inside the tooth. When the inner pulp of a tooth becomes inflamed or infected, a root canal may be the best way to save it. As a family dentist serving Mount Prospect, I see patients who avoid treatment because they fear a root canal will be painful. The truth is that modern root canals are highly effective and often provide immediate relief. Delaying necessary treatment can lead to serious complications, including tooth loss and infection spreading to other parts of the body.

Persistent Tooth Pain

Ongoing tooth pain is one of the clearest signs that a root canal might be necessary. If the pain lingers after eating or drinking, especially when consuming hot or cold items, the nerve inside the tooth may be inflamed. Pain that worsens over time rather than improving is another warning sign. The discomfort may be constant or come in waves, but if it does not go away, the problem will not resolve on its own.

Sensitivity To Hot And Cold

A tooth that reacts strongly to temperature changes could have nerve damage. Brief sensitivity is common, but if the discomfort lingers for more than a few seconds, it could indicate that the tooth’s pulp is compromised. The pain might start mild and become more intense, signaling an infection inside the tooth.

Swollen Gums Around The Affected Tooth

Swelling around a specific tooth may be a sign of deep infection. If the gums appear red, tender, or puffy near the affected tooth, an abscess may have formed. In some cases, a small pimple-like bump may appear near the tooth, which is a clear indication of an infection. The swelling might come and go, but that does not mean the problem has gone away.

Deep Decay Or A Cracked Tooth

When decay reaches the inner layers of a tooth, a filling is often not enough to repair the damage. A cracked tooth can also allow bacteria to reach the pulp, causing an infection. Even if there is no immediate pain, a deep cavity or visible crack should be treated before the damage worsens. If bacteria have already spread inside the tooth, a root canal may be necessary to prevent further problems.

Discoloration Of The Tooth

A tooth that has turned gray or darker than the surrounding teeth may be a sign of internal damage. This often happens when the nerve inside the tooth has died due to trauma or decay. Unlike surface stains from coffee or smoking, this type of discoloration comes from inside the tooth and requires professional treatment.

Why Ignoring These Signs Can Lead To Bigger Problems

Some people try to ignore tooth pain, hoping it will go away. Unfortunately, an infected tooth does not heal on its own. Left untreated, the infection can spread to the jaw, sinuses, or bloodstream, leading to serious health issues. A root canal removes the infected tissue and seals the tooth to prevent further damage.

Delaying treatment can also mean more invasive procedures later. If the infection progresses too far, the tooth may need to be extracted, requiring a dental implant or bridge to replace it. A root canal is a safe and effective way to save a tooth and restore comfort.

Frequently Asked Questions About Root Canals

How Do I Know If I Need A Root Canal Or Just A Filling?

A small cavity can often be treated with a filling, but if the decay reaches the inner pulp of the tooth, a root canal is necessary. If you experience persistent pain, swelling, or sensitivity that does not improve, a root canal may be required. X-rays and a dental exam help determine the best treatment option.

Will A Root Canal Hurt?

Many people worry about pain during a root canal, but the procedure is designed to relieve pain, not cause it. With modern anesthesia, the process is no more uncomfortable than getting a filling. Most patients feel significant relief once the infected tissue is removed.

How Long Does A Root Canal Take?

Most root canals can be completed in one or two appointments. The first visit involves removing the infected tissue and cleaning the inside of the tooth. A second visit may be needed to place a permanent crown, which protects the tooth from further damage.

What Happens If I Don’t Get A Root Canal?

Ignoring an infection inside a tooth can lead to severe pain, abscess formation, and even tooth loss. The infection can spread to other parts of the body, increasing the risk of serious health complications. In many cases, extracting the tooth becomes the only option if a root canal is not performed in time.

How Long Does A Root Canal Last?

With proper care, a root canal-treated tooth can last a lifetime. A crown is usually placed over the tooth to provide strength and protection. Regular brushing, flossing, and dental checkups help ensure long-term success.

Can I Eat After A Root Canal?

It is best to wait until the numbness wears off before eating. Soft foods are recommended for the first day or two. Avoid chewing on the treated tooth until a permanent crown is placed to prevent damage.

How Much Does A Root Canal Cost?

The cost of a root canal varies depending on the complexity of the case and whether a crown is needed. Most dental insurance plans cover part of the procedure. During a consultation, I provide a cost estimate and discuss payment options.

Will My Tooth Feel Different After A Root Canal?

Once the infection is removed, the pain and sensitivity should be gone. The tooth may feel slightly different because the nerve has been removed, but it will function normally. A crown helps restore strength and appearance.
