What problem may arise if crowns cause an impingement on gums?

When crowns cause an impingement on the gums, the primary concern is gum health issues. This impingement can lead to inflammation of the gingiva, a condition known as gingivitis. The gum tissues can become irritated, resulting in symptoms like redness, swelling, and tenderness. If this condition persists, it may lead to more severe periodontal issues such as periodontitis, which can jeopardize not only gum health but also the supporting structures of the teeth.

Inadequate fit or design of crowns can disrupt the natural contour of the gum tissue, causing pockets to form where plaque and bacteria can accumulate, further worsening the situation. Therefore, addressing and ensuring proper crown placement is essential for maintaining the health of the periodontal tissues.
