The Gap Between Your Dental Crown And Gums: How To Fix It?


Have you noticed a small gap between your dental crown and gum line? If so, you’re not alone. Many people experience this issue without realizing it until discomfort, sensitivity, or even bad breath becomes a concern. A properly fitted dental crown should sit snugly against the gum, but sometimes gaps can form due to various reasons, potentially leading to serious oral health problems.
Ignoring this gap can lead to complications such as trapped food particles, bacterial buildup, and even gum disease. Fortunately, modern dentistry has successful ways to fix this issue and restore your oral health. In this article, we’ll explore the causes of the gap behind your dental crown, how to detect it, and most importantly, what you can do to fix it.
What Causes the Gap Between Crown and Gum?
For several reasons, your gum and crow make gaps, so it is crucial to understand the root cause, which can help you prevent future dental problems.
1. Receding Gums
A gap between your dental crown and gum often happens because of gum recession. This means your gums start pulling away from the tooth, leaving the root exposed and creating an open space. Several factors can lead to this, including :
- Poor oral hygiene leads to gum disease
- Aggressive brushing, which wears down gum tissue
- Aging, as gums naturally recede over time
- Smoking, which reduces blood flow to the gums
2. Poorly Fitted Crown
If a crown is not properly fitted during placement, it may not sit flush against the gum line. This can happen due to:
- Improper impressions are taken before crown fabrication
- Changes in gum structure after crown placement
- Poor bonding, causing the crown to shift slightly
3. Natural Wear and Tear
Over time, a crown can wear down, especially if you grind your teeth or put excessive pressure on it while chewing. This gradual deterioration can cause small gaps to develop between the crown and gum.
4. Tooth Decay Under the Crown
If bacteria accumulate under the crown due to inadequate oral hygiene, decay can occur beneath the crown. As the decay progresses, the natural tooth structure beneath the crown may shrink, leading to a noticeable gap.
5. Crown Loosening or Dislodging
A crown can loosen over time due to daily wear, clenching, or improper bite alignment. When this happens, the gap becomes more noticeable, increasing the risk of bacterial buildup.
Detecting the Gap: Signs and Symptoms
Not sure if you have a gap between your crown and gum? Here are some signs to look out for:
1. Sensitivity to Hot and Cold
If you feel a sharp sensation when consuming hot or cold foods, it could indicate that your tooth’s root is exposed due to a gap.
2. Food Getting Stuck
A gap can trap food particles, making it difficult to clean the area properly. If you frequently find food caught near your crown, this might be a sign of an issue.
3. Bad Breath or Unpleasant Taste
A gap allows bacteria to accumulate, leading to bad breath or an unpleasant taste in your mouth. If you notice persistent bad breath despite brushing and flossing, the gap may be the cause.
4. Visible Space Between Crown and Gum
Stand in front of a mirror and inspect your crown closely. If you notice a visible space between your crown and gum line, it’s time to take action.
5. Gum Inflammation or Bleeding
Gaps between the crown and gum can irritate the soft tissue, leading to redness, swelling, and bleeding when brushing or flossing.
How to Fix the Gap Between Crown and Gum?
Once you’ve detected a gap, the next step is to fix it. Here are some solutions:
1. Dental Crown Replacement
If the gap is significant or the crown is old and worn, replacing it may be the best option. Your dentist will remove the existing crown, clean the area, and place a new, properly fitted crown to ensure a snug fit.
2. Gum Grafting for Receding Gums
If gum recession is the cause, a gum graft may be necessary. This procedure involves taking healthy gum tissue from another part of the mouth and attaching it to the affected area to close the gap.
3. Dental Bonding to Close Small Gaps
For minor gaps, dental bonding can be a quick fix. Your dentist will apply a tooth-colored resin material to fill the space and smooth out the transition between the crown and gum.
4. Deep Cleaning and Improved Oral Hygiene
If bacteria and plaque buildup are contributing to the problem, a deep cleaning can help. Scaling and root planing remove harmful deposits, promoting gum health and preventing further recession.
5. Adjusting the Crown Placement
In some cases, the dentist may be able to adjust the crown rather than replace it. If the gap is due to minor shifting, the crown can sometimes be repositioned to fit more securely.
Avoiding Bad Habits That Worsen Gaps
Prevent further gum recession by:
- Using a soft-bristled toothbrush to avoid aggressive brushing
- Flossing gently and correctly
- Wearing a nightguard if you grind your teeth
- Scheduling regular dental checkups to monitor crown health
Preventing Future Gaps After Crown Placement
Once your gap is fixed, you’ll want to prevent it from happening again. Follow these tips:
- Maintain Proper Oral Hygiene: Brush twice daily, floss regularly, and use antibacterial mouthwash to keep your gums and teeth healthy.
- Visit Your Dentist Regularly: Routine dental checkups help identify and address potential issues before they worsen.
- Monitor Gum Health: If you feel your teeth getting sensitive and notice any signs of gum recession, see your dentist immediately.
- Avoid Hard or Sticky Foods: Biting into hard foods can put pressure on your crown, causing it to shift or loosen over time.
A small gap between your dental crown and gum might not signal a big oral issue, but it can lead to serious issues if ignored. Whether caused by gum recession, a loose crown, or everyday wear, addressing it early is crucial. If you notice a gap, don’t wait—visit your restorative dentist to ensure a proper fit and protect your oral health.
Home Care and Maintenance Tips
If you notice a gap but can’t see a dentist right away, or if you’ve just had the issue professionally addressed, here are some home care tips to help manage and prevent further problems:
- Maintain Good Oral Hygiene: Brush twice a day and floss daily, especially around the crowned tooth. Consider using a water flosser to gently remove trapped food particles.
- Use Antibacterial Mouthwash: This can help reduce bacteria around the gumline and minimize inflammation.
- Avoid Sticky Foods: Sticky or hard foods can dislodge crowns or worsen gaps. Stick to a soft, balanced diet until the issue is resolved.
- Inspect the Area Regularly: Keep an eye on changes in color, swelling, or bleeding around the crowned tooth.
- Apply Saltwater Rinses: Rinsing your mouth with warm saltwater can soothe gum irritation and help maintain a healthy oral environment.
When to See a Dentist?
While some minor gaps might not seem urgent, here are signs you should seek dental care promptly:
- Persistent Pain or Sensitivity: This may signal underlying decay or gum infection.
- Bleeding Gums Around the Crown: This could indicate inflammation or early gum disease.
- Bad Breath or Unpleasant Taste: Bacteria trapped in the gap can cause halitosis.
- Visible Gap or Crown Movement: If your crown feels loose or looks shifted, see your dentist before it worsens.
- Food Trapping: If food frequently gets stuck in the gap, it could cause decay or infection.
Timely intervention can save your crown and protect the surrounding teeth and gums from more complex procedures in the future.
