An old dental crown does not need replacing just because it has been in your mouth for ten or fifteen years. However, a loose fit, new discomfort or changes around the gumline can mean it needs attention. Here are six signs your dental crown may need replacing, and what to check before a small problem becomes harder to treat.<\/p>\n\n\n\n

1. Your Crown Feels Loose or Moves When You Chew<\/h2>\n\n\n\n

A crown should stay securely in place when you eat and speak. If it rocks, clicks or shifts under pressure, the cement holding it may have weakened, or the tooth underneath may have changed.<\/p>\n\n\n\n

Do not test it by pulling or repeatedly moving it. Arrange a dental appointment promptly, because a loose crown can allow food and bacteria underneath and may eventually come off.<\/p>\n\n\n\n

Recementing may be possible if the crown and tooth remain healthy. However, the dentist must first establish why it became loose.<\/p>\n\n\n\n

If the crown falls out, keep it in a clean container and bring it to your dentist. Never use household glue to stick it back in place.<\/p>\n\n\n\n

2. You Can See a Crack, Chip or Worn Edge<\/h2>\n\n\n\n

Look for a new rough patch, a piece of ceramic missing or a sharp edge that catches your tongue. Even a small chip may affect comfort, and a deeper fracture can weaken the restoration.<\/p>\n\n\n\n

Not every damaged crown must be replaced. A dentist might smooth a minor rough area or repair selected surface damage, while a major crack may require a new crown.<\/p>\n\n\n\n

Crowns with a porcelain outer layer can sometimes chip while their underlying structure remains intact. Your dentist will check whether the damage affects the crown’s strength, appearance or ability to protect the tooth.<\/p>\n\n\n\n

Until it is examined, avoid biting hard foods directly on the damaged crown.<\/p>\n\n\n\n

3. The Crowned Tooth Has Started to Hurt<\/h2>\n\n\n\n

New sensitivity to cold, pain when biting or a persistent ache deserves attention. The cause could be decay near the crown edge, a crack in the supporting tooth, irritation inside the tooth or a problem with your bite.<\/p>\n\n\n\n

Pain does not automatically mean the crown has failed, and a tooth with a previous root canal can still develop an infection. An examination and, when appropriate, an X-ray help identify what needs treating.<\/p>\n\n\n\n

Seek urgent dental care for severe pain, fever or facial swelling. If swelling affects swallowing or breathing, seek emergency medical help immediately rather than planning dental travel.<\/p>\n\n\n\n

4. Food Keeps Getting Trapped Around One Crown<\/h2>\n\n\n\n

Does food regularly catch beside a crown even though it did not before? A contact point between teeth may have changed, or the crown edge may no longer fit as well as it should.<\/p>\n\n\n\n

Persistent bad taste or an unpleasant smell from the same area also deserves investigation. These changes do not prove there is decay, but bacteria and food can collect where cleaning is difficult.<\/p>\n\n\n\n

Sometimes the problem comes from a neighbouring tooth rather than the crown itself. The dentist needs to examine the entire contact area and check for decay beneath the crown edge.<\/p>\n\n\n\n

Depending on the findings, the solution may involve an adjustment, treatment of the affected tooth or a replacement restoration.<\/p>\n\n\n\n

5. The Gum Around the Crown Bleeds or Looks Different<\/h2>\n\n\n\n

Redness, tenderness, bleeding while brushing or a gumline that has receded can suggest a problem around an older restoration. Sometimes plaque is the main cause; in other cases, a poorly fitting edge makes cleaning more difficult.<\/p>\n\n\n\n

Do not assume replacing the crown alone will solve gum disease. The dentist should check the gums and address inflammation before deciding whether the restoration itself needs changing.<\/p>\n\n\n\n

6. Your Old Crown No Longer Matches Your Smile<\/h2>\n\n\n\n

A crown may look more yellow than neighbouring teeth, or its shape may seem out of place after years of changes to your smile. This can be a reasonable reason to ask about an aesthetic replacement, even if the crown still functions well.<\/p>\n\n\n\n

A grey or dark line near the gum does not always mean decay. Some older metal-ceramic crowns show a metal edge when the gum recedes; our article on dark lines around old dental crowns<\/a> explains the different causes.<\/p>\n\n\n\n

Whitening treatments do not change the colour of an existing ceramic crown. If you want a more balanced shade across your smile, discuss how replacement crowns would match your natural teeth.<\/p>\n\n\n\n
