What Happens If You Ignore a Tooth Infection?

A tooth infection is more than just a toothache. Without treatment, the infection can continue to spread, causing increasing pain, damage to the tooth and surrounding bone, and in some cases, more serious health complications. Prompt treatment often provides the best opportunity to save the tooth.

What Is a Tooth Infection?

A tooth infection occurs when bacteria enter the inner portion of the tooth, called the pulp.

This commonly happens because of:

• Deep tooth decay
• A cracked or broken tooth
• Trauma to the tooth
• A leaking filling or crown

Once bacteria reach the pulp, the tissue inside the tooth can become infected.

Can a Tooth Infection Go Away on Its Own?

Unfortunately, no.

Unlike some minor illnesses, an infected tooth does not typically heal without dental treatment.

The infection may temporarily become less painful if the nerve inside the tooth dies, but the bacteria usually remain.

Without treatment, the infection often continues to spread into the bone surrounding the tooth.

What Symptoms Can Develop?

As the infection progresses, you may experience:

• Persistent tooth pain
• Pain when biting or chewing
• Sensitivity to hot or cold
• Swelling of the gums or face
• A pimple-like bump on the gums (dental abscess)
• A bad taste or drainage in the mouth

Some infected teeth cause very little discomfort, which is one reason regular dental examinations are important.

What Happens to the Tooth?

Without treatment, the infection can destroy the pulp inside the tooth.

Over time, the tooth may become:

• Increasingly weakened
• More susceptible to fracture
• Less likely to be restored successfully

The longer treatment is delayed, the greater the chance the tooth may no longer be salvageable.

Can a Tooth Infection Damage the Bone?

Yes.

As bacteria spread beyond the root tip, they can destroy the bone supporting the tooth.

Bone loss may:

• Reduce the support around the tooth
• Make future treatment more complicated
• Affect neighboring teeth in severe cases

Early treatment helps limit this damage.

Can a Tooth Infection Spread?

It can.

Most tooth infections remain localized around the affected tooth, especially when evaluated and treated promptly.

However, if left untreated, an infection can spread into the surrounding tissues of the face and jaw. In rare cases, untreated dental infections can become serious medical emergencies requiring hospitalization.

Fortunately, prompt dental treatment greatly reduces this risk.

Can the Tooth Still Be Saved?

Often, yes.

Many infected teeth can be successfully treated with root canal therapy if the tooth is evaluated before extensive damage occurs.

However, if the infection or structural damage becomes too severe, extraction may become the better long-term option.

This is why early evaluation is so important.

How Is a Tooth Infection Treated?

Treatment depends on the condition of the tooth.

Options may include:

• Root canal treatment to remove the infection and preserve the tooth
• A dental crown to protect the restored tooth
• Tooth extraction if the tooth cannot be predictably saved

If swelling is present, additional treatment may also be necessary.

Our Total Oral Health Approach

At Total Dentistry, our goal is to preserve natural teeth whenever possible.

When you have a tooth infection, we don’t simply focus on relieving the pain. We evaluate why the infection developed, whether the tooth can be predictably restored, and what treatment offers the best long-term outcome.

Early diagnosis often allows for more conservative treatment and increases the likelihood that your natural tooth can be saved.

The Bottom Line

Ignoring a tooth infection usually allows the problem to worsen over time.

Early treatment can often eliminate the infection, relieve discomfort, and preserve your natural tooth before more extensive damage occurs.

If you’re experiencing tooth pain, swelling, or think you may have a tooth infection, contact Total Dentistry as soon as possible. Prompt evaluation can help determine the cause of the infection and the best treatment for your long-term oral health.
