A temporary dental crown acts as a temporary cap for a tooth prepared for a permanent restoration. This is a necessary step, ensuring the underlying tooth structure remains safe from damage and sensitivity while the permanent crown is being fabricated in a dental lab. Unlike permanent crowns, which are designed for long-term durability, the temporary version is not built to withstand the full force of normal chewing. It is secured with a temporary cement that allows for easy removal by the dentist later.
Understanding Temporary Crown Vulnerability
Temporary crowns are made from less durable materials, such as acrylic or composite resin, making them weaker than the final porcelain or metal crown. This material choice allows for quick fabrication or easy modification, but it leaves the crown susceptible to fracture. The crown’s primary function is to maintain the space between adjacent teeth and prevent the prepared tooth from shifting, which is important for the fit of the permanent restoration.
The temporary cement used to hold the crown in place is another point of vulnerability. Dentists use a cement that offers a balance of retention and easy removal. This cement is intentionally designed to be weaker than the permanent bonding agent, meaning it can break down or lose its hold when subjected to excessive force or sticky substances. This combination of a softer material and a weaker adhesive means the temporary crown is not meant for heavy chewing.
Specific Risks of Eating a Burger
A burger presents risks to a temporary crown due to the mechanics of eating it. The first major risk is dislodgement, often caused by the sticky or doughy nature of the bun and certain toppings. As the bread is chewed, it adheres firmly to the crown’s surface and can pull it off the tooth, overcoming the weak temporary cement bond.
The second risk is a fracture of the temporary acrylic material. Biting into a thick burger, especially one with tough or dense meat, requires a significant compressive force. This force, applied to the crown, can exceed the material’s structural limit, causing it to chip or crack. Finally, the wide opening of the mouth required to take a large bite of a stacked burger can introduce shearing forces that strain the temporary cement bond, potentially loosening the crown even before the chewing process begins.
Techniques for Safe Eating
To safely enjoy a challenging meal like a burger, cut the burger into small, manageable, bite-sized pieces before attempting to eat it. This practice eliminates the high compressive and shearing forces associated with taking a large initial bite. You must then chew every piece exclusively on the side of your mouth opposite the temporary crown.
By keeping all chewing forces away from the crowned tooth, you protect the temporary material and its adhesive bond. Also, avoid toppings that are particularly sticky or hard, such as caramelizing sauces or crunchy additions like pickles, as these can either pull the crown off or cause it to crack. Ensure the food is at a moderate temperature, as extreme heat or cold can increase tooth sensitivity and potentially weaken the temporary cement holding the crown.
Immediate Action If the Crown Comes Loose
If your temporary crown comes loose, act quickly to protect the underlying tooth, which is now exposed. Carefully retrieve the crown from your mouth to prevent swallowing. After rinsing the crown gently with warm water, contact your dental office immediately to schedule an appointment for re-cementing.
While waiting, you can attempt a temporary fix to protect the exposed tooth and reduce sensitivity. If the crown is intact, clean the inside and attempt to re-seat it using over-the-counter temporary dental cement, denture adhesive, or petroleum jelly. If the prepared tooth is sharp or causing irritation, covering it with dental wax can help protect the cheek and tongue until the dentist can reattach the crown.
