A cracked tooth can be tricky. Sometimes it causes sharp pain when you bite, and other times it produces only an occasional twinge that comes and goes, making it easy to ignore. But a crack rarely heals on its own, and left untreated it can deepen, become infected, or lead to the loss of the tooth. The good news is that when a cracked tooth is caught early, it can usually be treated and saved. Here is how to recognize the symptoms and understand your treatment options, from the team at Infinite Dental Wellness in Glendale, CA.
What Causes a Tooth to Crack?
Teeth are remarkably strong, but they are not indestructible. Cracks can develop suddenly from an injury or gradually from everyday stress over time. Common causes include biting down on something hard, an accident or sports injury, large old fillings that weaken the tooth, chronic teeth grinding, and the natural wear that comes with age. Sudden temperature changes, such as eating something very hot followed by something cold, can also contribute to small cracks in already vulnerable teeth.
Teeth that have had significant dental work in the past are especially prone to cracking, because each repair leaves a little less natural tooth structure to absorb the force of chewing. People who clench or grind their teeth, often without realizing it, place enormous repeated pressure on their teeth night after night, which can slowly propagate a crack. Even something as ordinary as chewing on a pen or crunching ice can be the final stress that causes an already weakened tooth to crack.
Symptoms of a Cracked Tooth
Cracked tooth symptoms can be intermittent, which is part of what makes them confusing. The classic sign is pain when biting down or, more tellingly, a sharp pain when you release your bite. Watch for these warning signs:
- Sharp pain when chewing or biting, especially when you let go
- Sensitivity to hot, cold, or sweet foods and drinks
- Pain that comes and goes rather than staying constant
- Discomfort that is hard to pinpoint to one specific tooth
- Swelling of the gum around a particular tooth
- A tooth that suddenly feels rough or has a visible line
Why You Should Not Wait
Because the symptoms can be mild or come and go, many people delay seeing a dentist. Unfortunately, a small crack can grow with continued chewing pressure until it reaches the inner pulp, where it can cause infection and severe pain. At that point, more involved treatment is needed to save the tooth. Seeing your dentist early often means a simpler, more conservative repair, and it greatly improves the chances that your natural tooth can be saved rather than lost. A crack that is ignored long enough can also allow bacteria to enter the tooth, leading to an abscess that may require urgent care.
Types of Tooth Cracks
Not all cracks are the same, and the treatment depends on the type and depth of the crack. Some are minor and cosmetic, while others extend deep into the tooth. Common types include:
- Craze lines: tiny surface cracks in the enamel that are usually harmless
- Fractured cusp: a piece of the chewing surface breaks off, often around a filling
- Cracked tooth: a crack extends from the chewing surface toward the root
- Split tooth: a crack divides the tooth into distinct segments
- Vertical root fracture: a crack that begins at the root and moves upward
Treatment Options
Treatment is tailored to the severity and location of the crack. For minor chips and shallow cracks, dental bonding or a tooth-colored filling may be enough to restore the tooth. A more significant crack often calls for a dental crown, which caps the entire tooth, holds it together, and protects it from further damage. If a crack has reached the pulp and caused infection, root canal treatment can remove the damaged tissue and save the tooth, after which a crown is typically placed for protection. In cases where a tooth is split or fractured too deeply to save, tooth extraction may be necessary, and your dentist can discuss replacement options such as a bridge or denture afterward.
Because the right treatment depends so heavily on how deep the crack runs, an accurate diagnosis is the first and most important step. Your dentist may examine the tooth closely, take X-rays, and ask you to bite on a special tool to pinpoint the crack and judge its severity. From there, the goal is always to choose the most conservative treatment that will reliably save the tooth. Catching a crack early frequently makes the difference between a simple repair and a more involved procedure.
How to Protect Your Teeth From Cracks
While not every crack can be prevented, several simple habits dramatically lower your risk. Protecting your teeth from excessive force is the common thread, whether that force comes from grinding, sports, or hard foods. The following steps go a long way toward keeping your teeth intact:
- Avoid chewing ice, hard candy, and other very hard items.
- Wear a custom night guard if you grind or clench your teeth.
- Use a mouth guard during contact sports.
- Have worn or large old fillings evaluated before they weaken the tooth.
- Keep up with regular checkups so small cracks are caught and treated early.
Keep in mind that even with the best care, a cracked tooth that has been repaired needs ongoing attention to make sure it stays healthy and the crack does not progress. Your dentist will monitor the tooth at future visits to confirm the restoration is holding up well. If you suspect a cracked tooth, do not wait for it to get worse.
