A cracked tooth can be a distressing experience. It might happen while biting into something hard, after an accidental injury, or even as a result of grinding your teeth over time. Regardless of how it happens, a cracked tooth can cause discomfort, sensitivity, or even pain.
The good news is that there are solutions available to address this issue and restore your smile.
In this article, we’ll explore the causes of cracked teeth, how to identify if you have one, and most importantly, how to fix a cracked tooth using both professional dental treatments and natural remedies.
By the end, you’ll have a clear understanding of what steps to take to protect your teeth and maintain your oral health.
What Is a Cracked Tooth?
A cracked tooth refers to a fracture or break in the tooth structure. It can occur in different parts of the tooth, including the enamel (the hard outer layer), the dentin (the middle layer), or even deeper into the pulp where the nerves and blood vessels are located. Cracks can range from minor surface lines to more severe fractures that compromise the integrity of the tooth.
Cracked teeth often fall into these categories:
- Craze lines: Tiny cracks in the enamel that are usually harmless.
- Fractured cusp: A break around the chewing surface, often affecting molars.
- Cracks extending below the gumline: These are more severe and may require extraction.
- Split tooth: A tooth that has split into two distinct parts, often requiring extraction.
- Cracked tooth syndrome: A condition where cracks are difficult to detect but cause discomfort when chewing.
Cracked Tooth Toothache Causes
A cracked tooth can cause pain for a variety of reasons:
- Pressure sensitivity: Chewing or biting down puts pressure on the crack, irritating the nerves inside the tooth.
- Exposure to temperature changes: Hot or cold foods and drinks can irritate the exposed dentin or pulp, causing sharp pain.
- Bacterial invasion: If the crack allows bacteria to enter the inner layers of the tooth, it can lead to infection and inflammation, causing a toothache.
If you experience consistent discomfort or cracked tooth toothache, it’s essential to consult a dentist to assess the extent of the damage.

How to Fix a Cracked Tooth
Fixing a cracked tooth depends on the severity of the crack and its location. Here are some professional dental treatments commonly used to repair cracked teeth:
1. Dental Bonding
For minor cracks or chips, your dentist may use a tooth-colored resin to bond the cracked area. Dental bonding is a quick and affordable solution, ideal for fixing a cracked front tooth. The resin is applied, shaped, and hardened with a special light to blend seamlessly with your natural tooth.
2. Dental Crown
For more significant cracks, a dental crown may be needed. A crown is a custom-made cap that covers the entire tooth, providing strength and protection. Crowns are particularly effective for molars or teeth that experience heavy biting pressure.
3. Root Canal Therapy
If the crack extends into the pulp of the tooth and causes an infection, root canal therapy may be necessary. During this procedure, the infected pulp is removed, and the tooth is cleaned and sealed. A crown is often placed on the tooth after the root canal to restore its strength.
4. Dental Veneers
If a front tooth is cracked but the damage is primarily cosmetic, your dentist may recommend veneers. These thin, custom-made shells are bonded to the front surface of the tooth, concealing the crack and improving the tooth’s appearance.
5. Tooth Extraction
In severe cases where the crack extends below the gumline or splits the tooth completely, extraction may be the only option. Once the tooth is removed, your dentist can discuss replacement options, such as a dental implant or bridge.

How to Fix a Cracked Tooth Naturally
While professional dental treatment is the most reliable way to fix a cracked tooth, there are some natural remedies you can try to manage discomfort and protect the tooth until you see a dentist.
1. Saltwater Rinse
Rinse your mouth with warm salt water to reduce inflammation and clean the area. This can help prevent bacteria from entering the crack and causing infection.
2. Clove Oil
Clove oil is known for its natural pain-relieving and antibacterial properties. Apply a small amount of clove oil to the affected area with a cotton swab to alleviate discomfort.
3. Avoid Hard Foods
Avoid chewing on the side of the mouth with the cracked tooth, and stay away from hard, crunchy, or sticky foods that could worsen the crack.
4. Use a Cold Compress
If the cracked tooth is causing swelling or pain, apply a cold compress to the outside of your cheek for 10–15 minutes. This can help reduce inflammation and numb the area.
5. Maintain Good Oral Hygiene
Keep the cracked tooth clean by brushing gently with a soft-bristled toothbrush and using an alcohol-free mouthwash.
While these natural remedies can provide temporary relief, they are not a substitute for professional treatment. A dentist will be able to assess the extent of the damage and provide a long-term solution.
Cracked Tooth Syndrome: What You Need to Know
Cracked tooth syndrome refers to tiny cracks in a tooth that are difficult to detect, even on X-rays. These cracks can cause intermittent pain when chewing or biting, especially if the crack affects the inner structures of the tooth.
If you suspect you have cracked tooth syndrome, it’s important to consult your dentist. They may perform a bite test or use magnification tools to identify the crack and determine the best course of action.
How to Prevent Cracked Teeth
Preventing cracked teeth is always better than fixing them. Here are some tips to protect your teeth:
- Avoid biting hard objects: Don’t chew on ice, popcorn kernels, or hard candies.
- Wear a mouthguard: If you grind your teeth at night or play contact sports, use a custom-fitted mouthguard to protect your teeth.
- Practice good oral hygiene: Brush and floss regularly to keep your teeth strong and healthy.
- Address dental issues promptly: Treat cavities, gum disease, and other dental problems early to prevent them from weakening your teeth.
When to See a Dentist
If you suspect you have a cracked tooth, it’s essential to see a dentist as soon as possible. Delaying treatment can worsen the crack and lead to complications like infection or tooth loss.
Signs you should visit a dentist include:
- Persistent toothache or sensitivity.
- Sharp pain when chewing or biting.
- Visible cracks or chips in your tooth.
- Swelling or redness around the tooth.
