When people refer to a “root canal falling out,” they typically mean the temporary filling or the permanent dental restoration, such as a crown, that was placed after the root canal procedure. If this protective covering becomes dislodged, it exposes the treated tooth, making prompt attention important to prevent complications.
Immediate Steps to Take
If a crown or filling dislodges, carefully retrieve the piece and store it in a clean container, as your dentist may be able to re-cement it. Immediately rinse your mouth with warm water or a saltwater solution to clean the area and help reduce bacteria.
To manage any discomfort, over-the-counter pain relievers like acetaminophen or ibuprofen can be used. Avoid consuming very hot or cold foods and drinks, as the exposed tooth may be sensitive to temperature changes. For temporary protection, apply dental wax or sugar-free gum to cover the area. Over-the-counter dental cement, available at pharmacies, can also temporarily secure the crown or fill the space, but always follow product instructions. These measures are temporary, so avoid chewing on the affected side of your mouth.
When to See Your Dentist
Contacting a dentist as soon as possible is important, even if there is no immediate pain. The exposed tooth is vulnerable to further damage and infection, as contaminants from food and saliva can enter, potentially leading to more complex dental problems, including reinfection. A dislodged crown is generally considered a dental emergency, warranting prompt professional attention.
Signs that indicate a more urgent situation include severe pain, swelling around the tooth, or difficulty eating. When you contact your dentist, inform them if the crown or filling is intact, if you are experiencing pain, and if you have used any temporary dental cement. Remember to bring the dislodged crown or filling to your dental appointment, as the dentist will need to inspect it.
Common Reasons for Dislodgement
Several factors can lead to a crown or filling becoming dislodged after a root canal procedure. New decay developing under the crown or filling is a common cause, as it can weaken the tooth structure and compromise the bond holding the restoration in place. The tooth treated with a root canal can also become more fragile due to the removal of the internal pulp, which may increase its susceptibility to fractures and dislodgement.
Everyday wear and tear, such as chewing forces or an improper bite, can gradually loosen the crown or filling over time. Physical trauma or a sudden blow to the mouth can directly dislodge a dental restoration. The dental cement used to bond the crown or filling to the tooth can weaken or wash away over time, leading to a compromised seal. An initial improper fit of the crown can also contribute to its eventual dislodgement.
Long-Term Solutions and Prevention
At your dental appointment, the dentist will assess the tooth and the dislodged restoration. If the crown is intact and the underlying tooth structure is healthy, the dentist may be able to re-cement the existing crown. If the crown is damaged, or if there is significant decay or insufficient tooth structure, a new crown will likely be fabricated. In severe instances where the tooth is extensively compromised, root canal retreatment or even extraction might be considered as a last resort.
Preventing future dislodgement involves consistent oral care and mindful habits. Maintaining good oral hygiene through regular brushing and flossing, particularly around the crown and gumline, helps prevent decay that can undermine the restoration. Regular dental check-ups are important for early detection of any issues with the crown or the underlying tooth. Avoiding hard, sticky, or chewy foods can reduce stress on the dental work. If you grind your teeth, discussing a custom night guard with your dentist can help protect your dental restorations from excessive forces.
