Signs a Tooth Needs a Crown
Most people don't notice a crown problem all at once. They notice something small. Maybe a tooth twinges when you chew on one side. Maybe your tongue keeps finding a rough edge that wasn't there last month. These are the signs that tend to point toward a crown.
- Pain when you bite down or let go. A quick, sharp pain that shows up when you release a bite can mean a crack in the tooth. Cracks are often too thin to see in a mirror. A crown holds the tooth together so the crack doesn't spread.
- A large filling that's cracking or wearing out. Big fillings leave less natural tooth around them. Over time, the tooth walls can get thin and weak. When there isn't enough tooth left to hold a new filling, a crown covers and protects what's there.
- A broken or badly chipped tooth. If a corner or cusp breaks off a back tooth, a filling may not have enough to grab onto. A crown rebuilds the shape so you can chew normally again.
- A back tooth that's had a root canal. A root canal saves the tooth, but molars and premolars take a lot of chewing force. A crown is often placed afterward to help keep the treated tooth from cracking.
- Teeth that are worn down flat. Grinding or clenching can wear teeth short over the years. When a tooth has lost a lot of height, a crown can bring it back.
- Decay that's too big for a filling. A cavity that has spread through much of the tooth may need more coverage than a filling can give.
Crowns also come up in a couple of other cases. An implant needs a crown on top to work like a tooth, and that falls under implant restoration. A tooth that's badly misshapen or stained can sometimes be covered with a crown, too, though veneers or bonding may fit better for front teeth.
Not every tooth problem means a crown. A small cavity is usually fixed with a filling. A minor chip on a front tooth can often be smoothed or repaired with cosmetic bonding. Cold sensitivity that comes and goes may have nothing to do with the tooth's strength. A crown makes sense when the tooth needs protection, not just a patch.
The hard part is that two teeth can feel the same and need very different things. A sore bite might be a crack, a high filling, or a gum issue. That's why an exam matters more than any checklist. At our office, Dr. Thum can look at the tooth, tell you what's going on, and explain whether a crown is the right repair or whether something simpler will do the job.
