Porcelain crowns improve aesthetics and chewing function. However, some people experience gingivitis after getting porcelain crowns, with symptoms like soft tissue swelling and bad breath. Understanding the causes and proper treatment will help you effectively protect your oral health.
Signs of Gingivitis after Porcelain Crowns
Porcelain crowns are a popular aesthetic restoration and chewing function improvement solution today. However, if not properly cared for, the gum area around the porcelain crown can become inflamed, seriously affecting facial structure, aesthetics, and even leading to jawbone loss.
Below are the signs of gingivitis after porcelain crowns that you need to pay special attention to:

Swollen, Red Gums Around Porcelain Crowns
Inflamed gums will appear bright red or dark red, swollen, and sensitive to touch. This is the earliest sign that the gum tissue is reacting to irritation, which could be due to bacteria, incompatible crown material, or poor hygiene.
Bleeding Gums When Brushing or Flossing
Bleeding gums are a common symptom when the gums are in a more severe stage of inflammation. If this condition recurs daily, you need to visit a dentist for examination as it may have progressed to periodontitis.

Persistent Bad Breath Despite Good Hygiene
Bad breath is a clear sign of plaque and bacteria accumulation causing gingivitis. The bad odor can spread when speaking, affecting confidence in communication and daily life.

Gum Pain and Sensitivity after Porcelain Crowns When Chewing or Biting
Gingivitis around porcelain crowns can cause pain and discomfort when chewing, and even a feeling of being stuck or obstructed when eating. This significantly affects chewing function.
Pus Around the Tooth Root or Crown
When the gums are severely inflamed, bacteria can penetrate deep into the soft tissue, leading to pus discharge. This is a warning sign that you might be experiencing a dental abscess – a dangerous complication of gingivitis after porcelain crowns that requires immediate treatment.

Receding Gums, Exposed Tooth Roots
Gum recession exposes the tooth neck, creating conditions for bacteria accumulation. If this condition persists, it not only causes sensitivity but also affects the aesthetics of your smile and increases the risk of loose or lost teeth.
Bitter Taste or Unpleasant Odor in the Mouth
A bitter taste or strange odor in the mouth is a consequence of bacterial decomposition in the inflamed gum area. This is a sign of progressing infection that should not be overlooked.
Causes of Gingivitis Due to Porcelain Crowns
Gingivitis around porcelain crowns is a fairly common condition that can stem from various causes. Among them, poor oral hygiene, ill-fitting crowns, excessive dental cement, or placing the crown too deep below the gum line are common factors causing gum irritation and infection. Additionally, some cases may involve sensitivity to crown materials or adhesives, leading to gum swelling, redness, and even progression to gum disease if not treated early. Detailed causes:
Poor Oral Hygiene
Not brushing and flossing correctly will lead to plaque and bacteria accumulation around the crown, causing gum inflammation and infection.
Ill-Fitting Crowns
When a porcelain crown does not fit snugly on the natural tooth, gaps will create conditions for bacteria to grow, easily causing gum irritation and gingivitis around the crown.
Excess Dental Cement
Using too much adhesive causes excess cement to overflow onto the gum line, leading to prolonged irritation and the risk of gingivitis.
Crown Placement Too Deep Below the Gum Line
When a porcelain crown is placed too deep under the gum, the gum is easily irritated, causing redness, swelling, and an increased risk of gum infection.
Sensitivity to Crown Material or Adhesives
Some individuals may react to the chemical components in crown materials or adhesives, causing gum irritation, gingivitis around the crown, or prolonged gum swelling.
Rough or Irregular Crown Margins
Rough or uneven crown margins easily trap food debris, creating conditions for plaque and bacteria to grow, leading to gingivitis.
Tooth Decay Beneath the Crown
If a natural tooth beneath the crown develops decay and is not detected in time, bacteria will spread, causing gingivitis, pain, and even deep-seated infection.

Effective and Safe Treatment for Gingivitis After Porcelain Crowns
Gingivitis after porcelain crowns is not an uncommon problem, affecting oral health, aesthetics, and chewing function. To prevent complications such as prolonged inflammation or alveolar bone loss, you should promptly visit a reputable dental clinic for examination and timely treatment if you notice signs of swelling, pain, bleeding, bad breath, etc.
Mild Gingivitis Treatment at Home
If gingivitis is still mild, you can apply some supportive home remedies:
Rinsing with warm salt water: This is a simple way to clean the oral cavity, eliminate bacteria, and effectively reduce swelling and pain.
Using betel leaves: Betel leaves have natural antibacterial properties. You can crush the leaves, boil them with water, let it cool, and then use it as a daily mouthwash. Additionally, you can apply it directly to the inflamed gum area to quickly soothe symptoms.
Non-Invasive Treatment with Pain Relievers
When gingivitis after porcelain crowns is not yet severe, a dentist may recommend non-invasive at-home treatment. Specifically, patients can use pain relievers such as Acetaminophen or Ibuprofen to reduce inflammation and pain. However, it is crucial to strictly follow the dentist’s professional instructions, avoiding self-medication and incorrect dosages to ensure oral health and prevent unwanted irritation.
Non-Invasive Treatment by Recrowning Porcelain Teeth
In cases where medication is no longer effective, the dentist may recommend recrowning the porcelain teeth. When the new restoration is performed correctly, the porcelain crown will fit snugly around the tooth, eliminating gaps that cause inflammation, thereby stabilizing the gums and preventing further issues. This is a non-invasive solution that helps preserve natural gum tissue to the maximum extent.
Invasive Treatment with Dental Surgery
If gingivitis progresses severely or shows signs of prolonged gum inflammation, invasive treatment measures are necessary to completely eliminate the inflammatory foci.
– Gingivectomy:
This method is often applied when alveolar bone loss occurs, leading to prolonged swollen gum tissue. The dentist will clean the inflamed gum area, then partially remove gum tissue to limit contact between the gum and the porcelain crown, thereby reducing irritation and preventing re-inflammation.
– Gum Grafting:
In more severe cases, when the biological width is compromised, intervention with a minor gum grafting surgery is necessary. The dentist will remove the old porcelain crown, proceed with biological width regeneration, and then wait approximately 20–30 days for the gum tissue to recover. Once the tissue is stable, a new porcelain crown will be placed, ensuring harmony and preventing the risk of recurrent infection.
In some cases, if home treatment methods are ineffective, the dentist will recommend recrowning the porcelain teeth to completely resolve the inflammation.
