Issues Related to Dental Crowns and Dental Floss


Hello Doctor, thank you for taking the time to respond and provide answers.
I previously underwent a root canal treatment, and I had a post and crown placed.
Recently, while using dental floss, I noticed that it gets caught near the crown, making it feel like the floss cannot be pulled out smoothly and is getting stuck on the crown.
I’m worried that if I pull too hard, I might dislodge the entire crown.
However, this issue does not happen every time; it only occurs at specific angles.

Question 1: Can the crown be dislodged if I pull hard on the dental floss? (Is the crown that easy to come off?)
Question 2: If the crown does come off, what should I do immediately?
Question 3: If the crown comes off, can I still eat? (I’m concerned about not being able to get to the dentist immediately to have it reattached...)
Question 4: If the crown comes off and I go to the dentist, will there be additional costs involved?
Thank you for your patience and assistance, I appreciate it.

Hello: 1.
It is possible that if you are concerned about it falling out, you can gently pull the dental floss out from the side after inserting it, avoiding any vertical up-and-down motions.
2.
Teeth that have already undergone root canal treatment should not be a major concern.
3.
Just avoid eating hard foods.
4.
You can return to your original clinic, and there should be no charges; however, if you go to another clinic, there may be a fee for adhesive materials.

Dear Patient,
Thank you for reaching out with your concerns regarding dental crowns and flossing issues. It’s important to address these matters to ensure your oral health remains optimal. Let’s break down your questions and provide some clarity.


Question 1: Can a dental crown come off if I pull too hard on the dental floss?
Dental crowns are designed to be securely bonded to the underlying tooth structure. However, if the crown was not properly fitted or if there is decay or damage to the tooth beneath, it may be more susceptible to coming loose. Generally, flossing should not cause a crown to come off if done gently and correctly. If you feel resistance while flossing, it’s advisable to avoid pulling too hard. Instead, try to gently maneuver the floss around the crown without forcing it.


Question 2: What should I do if my dental crown falls off?
If your dental crown does come off, the first step is to retrieve it if possible. Rinse it gently with water to clean it. Avoid using any adhesives or superglue to reattach it yourself, as this can lead to further complications. Instead, contact your dentist immediately to schedule an appointment. They will be able to assess the situation and determine whether the crown can be re-cemented or if a new crown is necessary.


Question 3: Can I eat if my dental crown has fallen off?
If your crown has come off, it’s best to avoid eating on that side of your mouth until you can see your dentist. Eating can expose the underlying tooth to bacteria and food particles, which could lead to further decay or infection. If you must eat, opt for soft foods and avoid sticky or hard items that could aggravate the situation.


Question 4: Will I incur additional costs if my dental crown falls off and I need to visit the dentist?
The costs associated with re-cementing a crown can vary depending on your dentist's office and your specific dental plan. If the crown was recently placed and is still under warranty or guarantee from the dentist, there may be no additional charge. However, if the crown has been in place for a while or if there are complications, there may be fees for the consultation and any necessary procedures. It’s best to discuss this with your dental office beforehand to understand any potential costs.


Additional Considerations:
1. Flossing Technique: Ensure you are using the correct technique when flossing around your crown. Gently slide the floss between your teeth and around the crown without forcing it. If you consistently experience issues, consider discussing this with your dentist, who may recommend alternative cleaning methods, such as interdental brushes.

2. Regular Check-ups: Regular dental check-ups are crucial for maintaining the integrity of your crowns and overall oral health. Your dentist can monitor the condition of your crowns and the underlying teeth, addressing any issues before they become significant problems.

3. Oral Hygiene: Maintaining good oral hygiene is essential. Continue to brush twice a day and floss daily, being careful around your crowns. Using an antibacterial mouthwash can also help reduce plaque buildup.

4. Sensitivity: If you experience sensitivity or discomfort around the crown, it’s important to inform your dentist. This could indicate an underlying issue that needs to be addressed.

In conclusion, while dental crowns are generally secure, it’s essential to handle them with care during your oral hygiene routine. If you have any further concerns or if the situation worsens, do not hesitate to reach out to your dentist for guidance. Your oral health is paramount, and addressing these issues promptly will help ensure a healthy smile.
