how to fix gap between crown and gum

A gap between your crown and gum line is a common dental problem that can lead to various complications if left untreated. This space, often referred to as a crown margin gap, allows bacteria and food particles to accumulate, potentially causing gum irritation, decay, and even tooth loss. This comprehensive guide explores the causes, consequences, and effective solutions for fixing this issue.

What Causes a Gap Between Crown and Gum?

Several factors can contribute to the development of a gap between a crown and the gum line. Understanding these causes is the first step towards effective treatment.

  • Gum Recession: As gums recede due to periodontal disease (gum disease), age, or aggressive brushing, the underlying crown margin becomes exposed, creating a gap.
  • Poor Crown Fit: An improperly fitted crown, either due to inadequate preparation of the tooth or inaccurate laboratory fabrication, can leave a space between the crown and the gum.
  • Cement Degradation: Over time, the dental cement used to secure the crown can degrade, leading to a loosening of the crown and the subsequent creation of a gap.
  • Wear and Tear: Normal wear and tear on teeth and crowns can contribute to the formation of gaps.
  • Changes in the Tooth's Structure: Changes in the tooth's structure, possibly due to injury or decay, can also result in a gap.

What are the Consequences of an Unfixed Gap?

Ignoring a gap between your crown and gum can lead to several serious dental problems:

  • Gum Inflammation (Gingivitis): Bacteria trapped in the gap can inflame the gums, causing redness, swelling, and bleeding.
  • Periodontal Disease: Persistent inflammation can progress to periodontal disease, leading to bone loss and potentially tooth loss.
  • Tooth Decay (Caries): Bacteria and food particles in the gap can cause decay around the crown margin and even affect the underlying tooth.
  • Crown Failure: The gap can weaken the crown's bond to the tooth, ultimately leading to crown failure and the need for replacement.
  • Sensitivity: The exposed tooth structure might lead to increased sensitivity to hot and cold temperatures.

How is a Gap Between Crown and Gum Fixed?

The treatment approach for a crown margin gap depends on the underlying cause and severity of the problem. Your dentist will determine the best course of action after a thorough examination.

1. Recontouring the Crown Margin:

In some cases, the dentist might be able to re-contour the crown margin to better fit the gum line. This often involves removing a small amount of the crown material to create a better seal.

2. Crown Replacement:

If the gap is significant or the crown is significantly damaged, replacement is often necessary. This involves removing the old crown and creating a new one that fits properly. Modern materials and techniques lead to more accurate and durable crowns.

3. Gum Grafting:

If gum recession is the primary cause of the gap, a gum graft might be recommended. This procedure involves taking tissue from another area of the mouth and grafting it onto the affected area to cover the exposed crown margin.

4. Periodontal Treatment:

If gum disease is contributing to the gap, addressing the underlying infection is crucial. This may involve scaling and root planing (deep cleaning) to remove plaque and tartar from beneath the gums.

How Can I Prevent a Gap Between Crown and Gum?

Regular dental checkups and proper oral hygiene are key to preventing gaps between crowns and gums.

  • Maintain excellent oral hygiene: Brush twice daily using fluoride toothpaste, floss daily, and use an antiseptic mouthwash.
  • Regular dental checkups: Visit your dentist for routine checkups and cleanings at least twice a year. This allows early detection and timely treatment of any developing issues.
  • Avoid harmful habits: Limit consumption of sugary and acidic foods and beverages, which can contribute to gum disease.

What is the Cost of Fixing a Gap Between Crown and Gum?

The cost of fixing a gap between a crown and gum varies widely depending on the treatment required, the location, and the dentist's fees. A simple re-contouring might be less expensive, while a crown replacement or gum graft can be significantly more costly. It's best to consult with your dentist for a personalized cost estimate.

Frequently Asked Questions (FAQ)

Does a gap between a crown and gum always need to be fixed?

Not always. Small gaps may not require immediate treatment, but it's essential to monitor the situation closely. Regular dental checkups are crucial to assess whether the gap is worsening or causing any problems.

How long does it take to fix a gap between a crown and gum?

The time required varies greatly depending on the chosen treatment. Simple re-contouring might take only one visit, while a crown replacement or gum graft may require multiple appointments over several weeks.

Will insurance cover the cost of fixing a gap between a crown and gum?

Coverage varies depending on your insurance plan. It's best to contact your insurance provider directly to determine your coverage for the specific procedure recommended by your dentist.

By understanding the causes, consequences, and solutions for a gap between a crown and gum, you can take proactive steps to maintain optimal oral health and prevent potential complications. Regular dental visits are crucial for early detection and timely intervention to avoid more extensive and costly procedures. Remember to consult your dentist for a proper diagnosis and personalized treatment plan.
