What Happens If You Ignore a Cracked Tooth?

What happens if you ignore a cracked tooth blog

It's easy to put off a dental visit. Life gets busy, and if something doesn't hurt, we often assume it isn't a problem. This mindset is particularly risky when it comes to a cracked tooth. You might notice a small line on your molar after biting down on something hard, or perhaps you feel a flicker of pain that comes and goes. We often tell ourselves it’s nothing, but ignoring a crack, no matter how small it seems, can lead to serious and complex dental issues. The structure of your tooth is compromised, creating an open door for bacteria.

Postponing a visit to our office allows the problem to escalate. A simple issue that we could have addressed with conservative treatment can evolve into a situation requiring more extensive procedures. We want to help you understand the significant risks associated with ignoring a cracked tooth. Addressing it early saves you discomfort, time, and money in the long run. Proper, timely treatment of cracked teeth is key to preserving your natural teeth and maintaining your oral health.

The Crack Can Worsen and Spread

When a tooth cracks, it loses its structural integrity. Think of it like a small crack in a car's windshield; at first, it might be a minor blemish, but with time and pressure, it inevitably spreads. The daily forces of chewing and biting place immense pressure on your teeth. Every meal and every clenched jaw puts stress on the compromised tooth, encouraging the crack to grow longer and deeper.

A small, superficial crack might only affect the outer enamel. We can often treat this type of crack simply. However, if you ignore it, the fracture can extend into the dentin, the sensitive layer beneath the enamel. From there, it can travel all the way to the pulp, which is the soft inner core containing the tooth's nerves and blood vessels. Once the crack reaches the pulp, the situation becomes much more serious. In some cases, the crack can even extend below the gumline and into the tooth root, which can put the entire tooth at risk of being lost.

You Risk Developing a Painful Infection

A crack in a tooth is more than just a structural problem; it’s a pathway for bacteria to invade the inner sanctums of your tooth. Your mouth is home to millions of bacteria, and while many are harmless, some can cause serious infections. A crack provides these harmful bacteria with direct access to the dentin and, eventually, the pulp.

From Discomfort to Abscess

When bacteria reach the pulp, the tissue becomes inflamed and infected. This condition, known as pulpitis, often causes significant pain, sensitivity to hot and cold temperatures, and discomfort while chewing. If you leave this infection untreated, the pulp will die, and the bacteria will continue to multiply. This can lead to the formation of a pocket of pus at the root tip, called an abscess. An abscess is a severe infection that can cause throbbing pain, swelling in your gums and face, and a persistent bad taste in your mouth. At this stage, the infection can spread to the jawbone and even other parts of your body, posing a serious threat to your overall health.

You Could Lose the Tooth Entirely

The ultimate consequence of ignoring a cracked tooth is losing it. While we always prioritize saving your natural teeth, a crack that is left to progress can cause damage so severe that extraction becomes the only viable option. Our ability to save a cracked tooth depends heavily on the location, direction, and extent of the fracture.

When Other Options Need Consideration

If a crack extends below the gumline and splits the tooth into two separate pieces, it is typically considered non-restorable. This is known as a split tooth. Similarly, a vertical root fracture, where the crack begins in the root and moves upward, often necessitates extraction because we cannot effectively seal the fracture to prevent infection. Losing a tooth affects more than just your smile; it can impact your ability to chew correctly, cause adjacent teeth to shift out of alignment, and lead to bone loss in your jaw. While dental implants and bridges are excellent replacement options, we believe preserving your natural tooth is always the best course of action. Prompt evaluation allows us to intervene before the damage becomes irreversible.

Don't Wait for the Pain

We understand the temptation to wait, but when it comes to a cracked tooth, time is not on your side. What begins as a minor issue can quickly spiral into a painful, complicated, and expensive problem. By seeking an evaluation as soon as you suspect a crack, you give us the best possible chance to save your tooth with conservative and effective treatment. Protecting your oral health is an investment in your overall well-being. If you notice a line on your tooth or experience sharp pain when biting, don't ignore it. Let us help you keep your smile healthy and complete.

Frequently Asked Questions About Cracked Teeth Treatment

How do you know if a tooth crack is severe?

A severe crack often causes symptoms like pain when chewing, sudden sensitivity to hot or cold temperatures, or discomfort that comes and goes. Visually, you might not see much, as many cracks are microscopic or hidden below the gumline. If the pain persists or you notice swelling in the gums near the tooth, the crack has likely allowed bacteria to infect the pulp, a serious condition requiring immediate attention. The only definitive way to know the severity is through a professional dental examination, which may include X-rays and other diagnostic tools.

What happens if a cracked tooth gets infected?

If a cracked tooth becomes infected, bacteria have entered the soft pulp tissue inside the tooth, leading to inflammation and pain. Left untreated, this infection will cause the pulp to die and can lead to an abscess, which is a pocket of pus that forms at the tooth's root. Symptoms of an abscess include severe, throbbing pain, swelling of the gums and face, and sometimes a fever. This infection can spread to the jawbone and other areas of the body, becoming a systemic health risk. To resolve the infection and save the tooth, endodontic treatment, such as a root canal, is typically necessary.
