Dental crowns are designed to protect damaged teeth, restore function, and improve appearance. For most patients, crowns feel natural and comfortable once healing is complete.
But what happens when you start feeling pain under a crown—days, months, or even years later?
If you’re experiencing discomfort, sensitivity, or pressure under a crowned tooth, it’s important not to ignore it. Pain under a crown usually means something is happening beneath the surface, and early treatment can prevent bigger problems.
Let’s break down the most common causes of crown pain, what symptoms to watch for, and when to see your dentist.
Is It Normal to Have Pain After Getting a Crown?
Mild sensitivity after a crown placement can be normal, especially during the first few days. Your tooth and surrounding tissues may feel slightly irritated from the procedure.
However, pain that is:
- sharp
- worsening
- persistent
- throbbing
- painful while biting
is not considered normal and should be checked.
Common Reasons for Pain Under a Crown
- The Crown Is Too High (Bite Misalignment)
One of the most common reasons for pain after crown placement is a crown that sits slightly too high.
Even a tiny difference in height can cause pressure when you bite down, leading to:
- soreness
- jaw discomfort
- sensitivity when chewing
- pain that feels worse while eating
This is usually easy to fix. Your dentist can adjust the bite so your crown fits correctly.
- Tooth Decay Under the Crown
Many people assume a crowned tooth can’t get cavities—but that’s a myth.
A crown covers the tooth, but bacteria can still enter at the gumline if there’s:
- a gap
- worn cement
- plaque buildup
- poor flossing habits
Decay under a crown can cause:
- sensitivity
- pain while chewing
- bad taste
- swelling around the tooth
If caught early, the crown may be replaced. If decay reaches the nerve, a root canal may be needed.
- Nerve Irritation or Inflammation (Pulpitis)
Sometimes the tooth nerve becomes irritated after crown preparation. This is more common when the tooth had deep decay or a large filling before the crown.
Signs of nerve irritation include:
- lingering sensitivity to hot or cold
- spontaneous throbbing pain
- discomfort that worsens at night
If the nerve inflammation becomes severe or irreversible, root canal treatment may be necessary.
- Infection or Abscess Under the Crown
If bacteria reach the inner part of the tooth, it can lead to infection. This can happen if the tooth was already compromised or decay developed under the crown.
Symptoms may include:
- severe throbbing pain
- swelling near the gums
- pus or drainage
- fever
- pain spreading to the jaw or ear
This is considered urgent and should be treated immediately.
- A Cracked Tooth Under the Crown
Even with a crown, the natural tooth underneath can still crack—especially if you grind your teeth or bite down on something hard.
A crack can cause:
- sharp pain when chewing
- pain that comes and goes
- sensitivity to cold
- discomfort that feels unpredictable
Cracked teeth are serious and may require crown replacement, root canal therapy, or in severe cases, extraction.
- Gum Recession Around the Crown
Over time, gums may recede, exposing the tooth root near the crown margin. This can cause sensitivity and discomfort.
Signs include:
- sensitivity to cold drinks
- visible gum recession
- discomfort while brushing
In some cases, gum recession also exposes crown edges, increasing the risk of decay.
- Cement Washout or Loose Crown
If the crown becomes loose or the cement wears down, bacteria can enter underneath, leading to irritation and decay.
Symptoms may include:
- pain when biting
- crown feeling “wiggly”
- food getting stuck around the crown
- discomfort that worsens over time
A loose crown should be fixed quickly to prevent further damage.
- Teeth Grinding (Bruxism)
If you grind your teeth at night, your crown may be under constant pressure. This can cause pain and soreness around the crowned tooth.
Grinding can also lead to:
- crown fractures
- cracked tooth underneath
- jaw pain
- headaches
A night guard is often recommended to protect your crown and teeth.
How to Tell What Type of Crown Pain You Have
Different symptoms often point to different causes.
Pain when biting down
Often linked to:
- high crown
- cracked tooth
- loose crown
Sensitivity to cold that goes away quickly
Often linked to:
- gum recession
- minor irritation
Lingering sensitivity to hot or cold
Often linked to:
- nerve inflammation
- possible need for root canal
Throbbing pain or swelling
Often linked to:
- infection or abscess
Pain that comes and goes
Often linked to:
- cracked tooth
- grinding
Only a dental exam and X-ray can confirm the real cause.
What Should You Do If You Have Pain Under a Crown?
If you feel pain under a crown, here’s what you should do:
- avoid chewing hard foods on that side
- avoid very hot or cold foods if sensitive
- keep the area clean with gentle brushing and flossing
- use over-the-counter pain relief if needed
- schedule a dental appointment as soon as possible
Waiting too long can allow decay or infection to spread.
Can Pain Under a Crown Go Away on Its Own?
Sometimes mild sensitivity may fade, especially after a new crown. But pain that lasts more than a week or worsens should never be ignored.
If the cause is decay, infection, or a cracked tooth, the problem will not heal without treatment.
How Dentists Treat Pain Under a Crown
Treatment depends on the cause. Your dentist may recommend:
- bite adjustment (if crown is too high)
- replacing the crown (if decay or poor fit exists)
- root canal treatment (if nerve is infected or inflamed)
- antibiotics (if infection is present, along with dental treatment)
- crown re-cementation (if crown is loose)
- extraction (only if tooth cannot be saved)
The sooner you visit, the more likely the tooth can be saved.
When Crown Pain Is an Emergency
Seek urgent dental care if you experience:
- facial swelling
- fever
- severe throbbing pain
- pus or gum boil near the tooth
- difficulty chewing or swallowing
- crown suddenly falling off with pain
These signs may indicate infection, which can spread quickly if untreated.
Pain Under a Crown Is a Warning Sign
A crown is meant to protect your tooth—not cause discomfort. If you’re feeling pain under a crown, it usually means something is happening beneath it, such as decay, bite issues, nerve inflammation, or infection.
The good news is that most crown problems are treatable, especially when caught early.
Don’t ignore the pain—your tooth may be trying to tell you something.
