Cracked teeth are one of the most common reasons people visit their dentist between regular checkups. Cracked teeth occur most frequently in patients over the age of forty. Although many cracks are minor and require minimal treatment, some are more severe and may require root canal treatment to save the tooth from extraction.
The Importance of Root Canal Treatment
Root canal treatment is an important dental procedure that can save a damaged or infected tooth from extraction. This treatment involves removing the damaged pulp and nerve from the tooth, cleaning and disinfecting the root canal space within the root, and filling it with a special material to prevent further infection. Here are some of the key reasons why root canal treatment might be necessary:
- Preservation of Natural Teeth. Root canal treatment allows you to keep your natural tooth rather than undergo extraction. Losing a tooth can lead to various dental issues, including misalignment of surrounding teeth, bone loss in the jaw, and difficulty chewing and speaking.
- Pain Relief. Root canal treatment can relieve the severe pain that often accompanies an inflamed or infected tooth. Removing the damaged pulp or nerve eliminates the pain source, allowing you to use the tooth for comfortable chewing.
- Prevention of Further Dental Issues. If a damaged or infected tooth is left untreated, it can lead to more serious dental issues such as abscesses, gum disease, or bone loss. Root canal treatment can prevent these issues by removing the damaged tissue and preventing more severe infection.
- A Cost-Effective Solution. In many cases, root canal treatment is a more cost-effective solution than tooth extraction and replacement with a dental implant or bridge. While the initial cost of root canal treatment may be higher than extraction, the long-term benefits and savings can be significant.
Causes of a Cracked Tooth
Cracks in teeth can range from minor ones that are not visible to the naked eye to severe fractures that expose the nerve and cause pain. The causes of cracked teeth include:
- Biting and Chewing Hard Foods. Eating hard foods such as ice, hard candy, or popcorn kernels can create cracks. Additionally, biting your nails, using your teeth to open bottles or packages, or chewing on other nonfood objects, places you at a higher risk of developing cracked teeth.
- Trauma to the Face or Mouth. Trauma during contact sports, falls, or a car accident can result in tiny hairline cracks or severely fractured teeth.
- Clenching and Grinding Teeth. If you grind or clench your teeth, you put excess pressure on them, which can cause cracks. This is a common problem for people under stress or anxiety. Over time, clenching and grinding can also wear down your teeth, making them more prone to cracking.
- Large Fillings and Tooth Decay. A large filling or cavity in your tooth can weaken its structure and make it more prone to cracking.
- Temperature Changes. Consuming hot or cold foods and drinks can cause your teeth to expand or contract, which makes your teeth more susceptible to cracks.
- Age. As you age, your teeth can become more brittle and more prone to cracking. This is a natural process that occurs due to changes in the composition of your teeth over time.
- Improper Bite. An improper bite can cause your teeth to wear down unevenly, leading to cracks. This can be caused by genetics, missing teeth, or other dental issues.
Solutions for a Cracked Tooth
If you have a cracked tooth, seeking treatment as soon as possible is vital to prevent further damage or infection. Several treatment options are available depending on the crack's severity and the tooth's location. Here are some typical solutions for a cracked tooth:
- Bonding. Dental bonding involves applying a tooth-colored resin to the tooth's surface to repair cracks. Bonding can improve the appearance of the tooth and prevent further damage.
- Crowns. Dental crowns are recommended for more severe cracks affecting the tooth's structure. A crown is placed over the entire tooth to protect it from further damage and restore its shape and function. Crowns can be made of porcelain, metal, or a combination of both.
- Onlays. Dental onlays are similar to crowns but are typically used when the crack is located on the top surface of the tooth. Onlays are made of porcelain or composite resin and are designed to fit the tooth's shape to protect it from further damage.
- Extraction. In some cases, if the crack is too severe and cannot be repaired, the tooth may need to be extracted. This is typically a last resort and is only recommended if other solutions are not possible.
Cracked Teeth and Root Canal Treatment
A cracked tooth can cause pain, sensitivity, swelling, and other dental issues due to inflamed or infected dental pulp. Sometimes, a cracked tooth may require root canal treatment to save the tooth and prevent further damage or infection. Here are some situations where a cracked tooth may require root canal treatment:
- Deep Cracks. If the crack extends into the pulp or nerve of the tooth, it will require root canal treatment to relieve pain and prevent severe infection.
- Large Fillings. A tooth with a large filling is prone to developing a crack that often affects the pulp. In addition, because the large filling compromises the tooth’s structure, it is also at risk of fracture and extraction if there is no early treatment.
- Severe Pain. Some cracks cause mild symptoms initially but worsen as the crack extends deeper into the tooth. Treating the crack during its early stages can often prevent the need for root canal treatment.
- Vertical Cracks. If the crack is vertical and extends into the tooth's root, it will likely require root canal treatment to save the tooth.
- Repeated Dental Work. If your tooth has had multiple fillings or other dental work in the past, it may be weaker and more prone to cracking. Due to chronic pulp inflammation, root canal treatment is more common in these cases.
- Fractured Cusps. If a portion of the tooth's cusps has fractured, it may require root canal treatment to remove the dental pulp and restore the tooth to its natural function.
- Trauma. Trauma to the face or mouth often causes deep cracks or fractures that increase the chance of root canal treatment to treat any damage to the pulp or nerve of the tooth.
