Signs a Cracked or Worn Tooth Needs a Crown
Most people don't wake up one morning knowing they need a crown. It creeps up. A tooth gets a little sensitive to cold, then it's fine for three weeks, then one day a piece of a granola bar makes you wince and you stop chewing on that side without even deciding to.
That avoidance is the real signal. Ask yourself which side you chew on. If you already know the answer, your mouth has been protecting that tooth for a while.
Here's what we look for when someone comes in describing that pattern:
- A quick jolt of pain when you bite down and then let go. That release pain is the classic sign of a crack flexing open.
- Cold sensitivity that lingers longer than a few seconds after the cold is gone.
- A rough edge you can feel with your tongue, or a chip you noticed after biting something hard.
- An old large filling with dark lines spreading out from its edges into the tooth.
- A tooth that's had a root canal and has no crown on it yet.
That last one matters more than people expect. A back tooth after a root canal is hollow and brittle, and it takes a lot of force every time you chew. We see those fracture straight down the middle when the crown gets put off too long, and once a crack runs below the gumline the tooth usually can't be saved.
Nine times out of ten, the person telling us "it only hurts sometimes" has a crack. Not decay. A crack.
So if a tooth has been on your mind for a month, that's your answer. Getting it looked at while it's still intact is a much smaller visit than rebuilding it after it breaks.
