Can a New Crown Help Prevent Food Trapping and Gum Disease? - Dentistry

Braces and Gingivitis


I had a root canal treatment on my second-to-last molar and received a crown.
I often experience food getting stuck in the gaps of that tooth, especially with chicken, which leads to gingivitis.
Doctor, if I were to redo the crown, would it help reduce the food getting stuck in the gaps?

Hello: I suggest that you first visit a dentist to check if the food impaction is caused by your dentures.
If there are cavities or periodontal disease in the gaps between your teeth, it could also lead to enlarged spaces.
It's important to confirm the cause first; if it is indeed due to the dental crown, then it should be redone.

When it comes to dental health, particularly regarding food trapping and gum disease, the design and fit of dental crowns (or caps) play a crucial role. If you've had a root canal treatment and subsequently received a crown, it's essential to ensure that the crown fits properly. A poorly fitting crown can create gaps that allow food particles to become trapped, leading to irritation and inflammation of the gums, which can ultimately result in gum disease.

In your case, where you are experiencing food trapping, especially with certain foods like chicken, it may indicate that the crown does not fit as snugly as it should. This can happen for various reasons, including the crown being slightly too large, not adequately contoured to the natural shape of your tooth, or the underlying tooth structure changing after the root canal treatment. If food is consistently getting stuck in the gaps, it can lead to plaque buildup, which can cause gingivitis or more severe periodontal disease if not addressed.

Redoing the crown could potentially resolve the issue if the new crown is designed and fitted correctly. A well-made crown should have smooth contours that mimic the natural tooth, minimizing any spaces where food can become trapped. Additionally, a new crown can be designed to better align with your bite, which can also help reduce the likelihood of food getting stuck.

It's also important to consider other factors that contribute to gum health. Regular dental check-ups and cleanings are essential, as your dentist can help remove any plaque or tartar buildup that may occur due to food trapping. Good oral hygiene practices at home, including brushing twice a day and flossing daily, are crucial in preventing gum disease. If food trapping continues to be a problem, your dentist may recommend additional measures, such as using an interdental brush or water flosser to help clean those hard-to-reach areas.

In summary, if you are experiencing persistent food trapping around your crown, it is advisable to consult your dentist about the possibility of remaking the crown. A properly fitted crown can significantly reduce food trapping and help maintain gum health, ultimately preventing gum disease. Additionally, maintaining good oral hygiene and regular dental visits will further support your dental health.
