Dental crowns are a popular solution for many dental problems, such as broken or damaged teeth. However, some individuals may experience the frustrating issue of their dental crowns frequently falling out. This can be both inconvenient and costly, as it may require multiple trips to the dentist for re-cementing or replacement. In this article, we will explore the various reasons why dental crowns may fall out and discuss potential solutions to prevent this recurring issue.
1. Poor Fit
One of the primary reasons why dental crowns can fall out is due to a poor fit. A crown that does not fit properly may become loose and eventually dislodged. This may occur if the crown was not accurately measured and fabricated in the dental laboratory or if there have been changes in the tooth structure since the crown placement.
It is essential to ensure that your dentist has the necessary expertise and uses high-quality materials to create and place the crown. Additionally, regular dental check-ups are crucial to detect any changes in the tooth structure and address them promptly.
Price range: The cost of dental crowns varies depending on factors such as the material used (porcelain, metal, ceramic) and the location of the dental practice. On average, dental crowns can cost between $800 and $2,500 per tooth.
2. Dental Decay
Dental decay or cavities can also contribute to the frequent falling out of dental crowns. When a tooth affected by decay is capped with a crown, the underlying decay can progress without being detected. This ongoing decay weakens the tooth structure and compromises the integrity of the crown, leading to its eventual dislodgement.
Regular brushing, flossing, and dental visits are crucial to maintaining good oral hygiene and preventing dental decay. It is essential to address any signs of decay promptly before placing a dental crown to ensure its long-term success.
3. Grinding or Clenching Teeth
Habitual grinding or clenching of teeth, known as bruxism, can exert excessive force on dental crowns, causing them to become loose and fall out. Bruxism is often a result of stress or an abnormal bite.
To prevent the damage caused by bruxism and prolong the lifespan of dental crowns, your dentist may recommend a custom-made nightguard to be worn during sleep. This nightguard acts as a protective barrier and reduces the force applied to the crowns.
4. Trauma or Injury
A sudden impact or trauma to the mouth can dislodge dental crowns. Accidents, falls, or sports-related injuries can lead to the crown becoming loose or completely dislodged. In some cases, the underlying tooth may also be fractured or damaged, contributing to the crown's failure.
If you participate in activities with a higher risk of dental trauma, such as contact sports, it is advisable to wear a mouthguard to protect both your natural teeth and dental crowns.
5. Poor Oral Hygiene
Poor oral hygiene and neglecting regular dental care can significantly affect the longevity of dental crowns. When plaque and bacteria accumulate around the margins of the crown, it can lead to gum disease and bone loss. The weakening of the surrounding structures can cause the crown to loosen and eventually fall out.
It is essential to practice good oral hygiene habits, including brushing twice a day, flossing daily, and scheduling regular dental cleanings and check-ups. Proper oral care can help maintain the health of the gums and ensure the stability of dental crowns.
6. Insufficient Tooth Structure
In some cases, dental crowns can fail due to an insufficient amount of tooth structure to support them adequately. This can occur if a significant portion of the tooth has decayed or fractured, leaving minimal healthy tooth structure for the crown to bond to.
If there is insufficient tooth structure to support a crown, your dentist may recommend other restorative options such as dental implants or bridges.
7. Allergic Reactions
In rare cases, a patient may develop an allergic reaction to the materials used in the crown, such as metals or dental cement. Allergic responses can lead to gum inflammation, discomfort, and ultimately, the dislodgement of the crown.
If you suspect an allergic reaction to your dental crown, consult your dentist immediately for an evaluation and possible replacement of the crown with an alternative material.
8. Aging or Wear and Tear
Over time, dental crowns may weaken and wear down due to regular use and the natural aging process. The cement holding the crown in place can also deteriorate, leading to the crown becoming loose or dislodged.
If your dental crowns have been in place for a significant period, it is advisable to visit your dentist regularly for routine check-ups. They can assess the condition of the crowns and recommend any necessary repairs or replacements.
9. Poor Dental Habits
Certain habits, such as biting on hard objects like ice or using teeth as tools, can put excessive stress on dental crowns and cause them to fall out. Additionally, habits like nail-biting or chewing on pens can also contribute to the weakening of the crown and its eventual failure.
Breaking these habits and adopting healthier dental practices can prevent unnecessary stress on the crowns and help maintain their longevity. Avoid using your teeth for anything other than chewing food to minimize the risk of crown dislodgement.
10. Inadequate Dental Procedures
Occasionally, the failure of dental crowns can be attributed to inadequate dental procedures, such as improper bonding or the use of low-quality materials. Choosing an experienced and reputable dentist who follows proper protocols is crucial to the success and longevity of dental crowns.
It is essential to do thorough research and seek recommendations before undergoing any dental procedures, including crown placements. Discussing the procedure in detail with your dentist and addressing any concerns can help ensure a successful outcome.
