Did you know that you could have a cracked tooth and not even know it? While some are very visible, others are hidden beneath the surface, only causing occasional discomfort. When left untreated, however, a crack can worsen over time and threaten the health of the entire tooth. 

Here is a look at how endodontists diagnose and treat cracked teeth. 

What Causes a Cracked Tooth?

Teeth are incredibly strong, but cracks can still happen for a variety of reasons, including: 

  • Biting down on hard foods or objects
  • Grinding teeth or clenching the jaw
  • Natural wear and tear with aging
  • Large fillings or previous dental work
  • Trauma or injury to the mouth

You may recognize these things when they happen, or you may not even think twice. It is not unusual for patients to not realize that their tooth is cracked. For others, the immediate pain may be felt, or a gradual discomfort that comes and goes. 

How Do I Know If I Have a Cracked Tooth?

It can help to understand the common symptoms of a cracked tooth since it isn’t always noticeable. And while pain and discomfort can be present, they are not the only signs to look out for. 

Pain while chewing and biting, sensitivity to hot and cold temperatures, swelling or irritation around the affected tooth, and intermittent pain that is difficult to pinpoint are all symptoms of a cracked tooth. 

Remember, you may not even know your tooth is cracked. Yet, even the smallest cracks can allow bacteria to enter the tooth and cause inflammation or infection within the pulp. Seeking treatment for cracked teeth early will give you the greatest chance of saving the natural tooth before the damage becomes more severe.

How Endodontists Make a Diagnosis

Specialized care is often necessary to diagnose and address a cracked tooth, especially since they require more than just a standard visual exam. Many cracks are too small to see with the naked eye or may be found below the gumline. Endodontists know this and use advanced diagnostic technology to accurately identify cracks and determine the best course of treatment. 

One of the most valuable tools includes a CBCT (3-D) imaging machine. This system provides highly detailed views of the tooth and its surrounding structures to help them detect fractures that traditional X-rays miss. 

Aside from this, endodontists will take into consideration the patient's symptoms, dental history, bite patterns, tooth sensitivity, and signs of inflammation or infection. Specialized microscopic tools can be used to examine the tooth more closely and uncover subtle cracks. 

How are Cracked Teeth Treated? 

An endodontist always strives to save a natural tooth. And doing this is rather easy since there are many treatment options available. The key is determining the right treatment option, taking into account the size, location, and severity of the crack.

Endodontic microsurgery involves minimally invasive procedures performed under microscopes for precision. It effectively repairs damaged teeth and surrounding tissues, and saves patients from having to deal with a missing tooth and all that comes with it. 

Dental crowns are another option to restore the functionality and integrity of a cracked tooth. And, root canal therapy may be necessary if there is infection in the pulp area. Extraction is always a last resort. 

Routine dental care and acting swiftly when something doesn’t feel right can ensure you maintain a healthy smile today and in the future. 

Frequently Asked Questions

Can a cracked tooth heal on its own? 

No, a cracked tooth cannot repair itself. Professional treatment is necessary to keep the crack from expanding. 

Does every cracked tooth need a root canal? 

No. Some minor cracks can be treated with a crown alone. A root canal is only needed if the crack reaches the pulp or causes infection. 

How do I know if my tooth is cracked? 

Symptoms like pain while chewing, temperature sensitivity, or discomfort that comes and goes are all warning signs. Routine dental care and an evaluation by an endodontist can confirm the diagnosis. 

Is treatment for a cracked tooth painful?

No. With advanced techniques and anesthesia, patients can remain comfortable throughout their treatment. 

What happens if I ignore a cracked tooth? 

Untreated cracks can worsen over time, potentially causing infection, severe pain, or tooth loss.
