Do Dental Crowns Make Your Breath Smell?

Dental crowns are a common restorative solution for damaged or weakened teeth, restoring their shape, size, strength, and appearance. While beneficial, some individuals express concern about whether these restorations might cause an unpleasant breath odor. This article explores the link between dental crowns and breath freshness.

Crowns and Odor: Understanding the Link

Dental crowns, typically made from materials like porcelain or metal alloys, do not inherently produce bad breath. When properly placed, a crown covers and protects the underlying tooth, integrating seamlessly with the rest of the mouth. However, issues with the crown or oral hygiene practices around it can contribute to unpleasant odors. It is often conditions around or beneath the crown, rather than the crown material itself, that lead to breath concerns.

Specific Reasons for Bad Breath Around Crowns

Poorly Fitting Crowns

Bad breath often stems from a poorly fitting crown. If the crown does not fit snugly, gaps can form where it meets the gum line. These spaces trap food particles and oral bacteria, providing a breeding ground for odor-producing microorganisms. This leads to plaque buildup and persistent odor.

Decay Under the Crown

New decay underneath the crown is another cause of odor. Bacteria can penetrate through tiny gaps or compromised seals at the crown’s margin. Once under the crown, these bacteria can cause new cavities to form. This decay creates an environment where odor-producing bacteria thrive, leading to an unpleasant smell.

Gum Inflammation or Disease

Gum inflammation or disease around the crowned tooth also contributes to bad breath. If a crown is not properly contoured or oral hygiene is neglected, it can irritate the surrounding gum tissue. This irritation can progress to gingivitis or periodontitis. Both conditions involve bacterial accumulation and inflammation, releasing volatile sulfur compounds.

Food Traps and Cleaning Challenges

Challenges with cleaning around the crown can lead to food traps. Crown contours might create areas where food particles get stuck, even with diligent brushing. If not effectively removed, they decompose and attract odor-causing bacteria. This localized bacterial activity can produce an unpleasant smell.

Pre-existing Issues or Excess Cement

Pre-existing dental issues that led to crown placement might not be fully resolved. An infection not cleared before crowning, or underlying gum issues, might persist. Additionally, excess dental cement left from the procedure can attract bacteria, causing an unpleasant taste and smell.

Maintaining Fresh Breath with Dental Crowns

Oral Hygiene

Maintaining fresh breath requires diligent oral hygiene. Brush twice daily with fluoride toothpaste, focusing on the crown’s gum line to remove food particles and plaque. Floss daily to clean between teeth and around the crown. Interdental brushes or a water flosser can further enhance cleaning.

Regular Dental Visits

Regular dental check-ups and professional cleanings are important. These visits allow a dentist to examine the crown for signs of poor fit, decay, or gum irritation. Early detection prevents issues from escalating and contributing to persistent bad breath. Professional cleanings also remove stubborn plaque and tartar buildup.

Consult Your Dentist

If bad breath persists despite thorough home care, consult a dentist. A professional can diagnose the specific cause, such as an ill-fitting crown, decay, or gum disease. Addressing the underlying issue, which might involve adjusting or replacing the crown, treating decay, or managing gum disease, is key to resolving the odor.

Dietary Considerations

Dietary choices influence oral health and breath freshness. Limit sugary and acidic foods to reduce bacterial growth. Avoid hard or sticky foods to prevent crown damage. Staying hydrated stimulates saliva production, naturally cleansing the mouth and washing away odor-causing bacteria.
