How long should tooth pain last after getting a crown?

The process of getting a crown involves a few steps, one of which is getting a temporary crown. A temporary crown is a protective layer that is placed for the time till the permanent crown gets fabricated in the lab.

It is normal for a tooth to be sore/ sensitive for the first 24-48 hours after getting a temporary or a permanent crown.

This can be due to high points, food lodgment, post-operative effects of local anesthesia, pressure of a foreign material, or irritation of the gums due to dental cement. 

Pain After Permanent Crown Placement: Causes and Relief

High points are generally adjusted immediately after the crown procedure. When an anesthetic is used during the crown procedure, its numbing effects can last for a few hours.

During this time, the lips or cheeks are more prone to burn, bite or get ulcers and cause pain/sensitivity before the numbing waives off.

There may also be some bruising and inflammation at the site of the anesthetic injection shortly after the dental crown procedure, particularly on the lower jaw. This should go away spontaneously without the need for treatment.

If you are currently at home dealing with an aching crown, one of these seven issues is likely the culprit:

1. Natural Tissue Trauma (Sore Gums)

The tooth under the crown is surrounded by sensitive ligaments, bone, and gum tissue. During the procedure, the dentist must drill and shape the tooth to fit the crown. This process naturally irritates the surrounding tissue.

• The Symptom: A dull, generalized ache and tender, swollen gums.
• The Solution: This is normal and fades within 3 to 4 days.

2. A "High" Bite

This is the most common reason for crown pain. If the crown is even a micro-millimeter too tall, it hits your opposite teeth before the rest of your mouth closes. This puts immense, isolated pressure on the single tooth root.

• The Symptom: A sharp, localized pain precisely when you bite down or chew food.
• The Solution: Visit your dentist. They will use a piece of articulating paper to find the high spot and gently polish it down.

3. Nerve Inflammation (Pulpitis)

If your crown was placed over a live tooth (meaning you did not have a root canal first), the nerve inside the tooth (the pulp) might have become inflamed from the drilling process or the cement.

• The Symptom: Severe sensitivity to hot or cold temperatures that lingers for minutes, or a throbbing pain that happens even when you are not eating.
• The Solution: If the inflammation is mild, it will heal on its own. If it is severe and irreversible, you will likely need a root canal.

4. Teeth Grinding (Bruxism)

If you chronically clench or grind your teeth in your sleep, you are putting massive, unnatural pressure on your new crown.

• The Symptom: Waking up with a sore jaw, a headache, and aching pain around the crowned tooth.
• The Solution: Your dentist can fabricate a custom night guard for you to wear while you sleep.

5. Poor Crown Fit or Cement Leakage

If the crown does not fit perfectly against your natural gumline, or if the dental cement has slightly washed out, microscopic gaps are left behind.

• The Symptom: Severe sensitivity, especially to sugary foods, or a bad taste in your mouth.
• The Solution: The dentist will need to re-cement the crown or, in rare cases, have a new crown fabricated to ensure a tight seal.

6. Recurrent Decay Under the Crown

A crown cannot get a cavity, but the natural tooth stump underneath it certainly can. If bacteria breach the seal of an older crown, rot can begin at the gumline.

• The Symptom: Localized pain, sensitivity, and sometimes a foul odor around the tooth.
• The Solution: The crown must be removed, the decay treated, and a new crown placed.

7. A Fractured Tooth

If the natural tooth beneath the crown develops a hairline crack—often from chewing on hard foods or ice—it can expose the inner pulp.

• The Symptom: Sharp pain specifically upon releasing a bite.
• The Solution: Depending on the severity of the crack, the tooth may need a root canal, or in worst cases, an extraction.

If the pain continues beyond several weeks or it is severe, it may be necessary to seek dental advice to investigate the situation. While it is normal for the crown to feel strange as patients get used to the feel of it in their mouth, in some cases the crown may need some adjustment to properly fit the shape of the mouth. 

Every mouth heals differently, but here is a general timeline to help you gauge whether your pain is normal or abnormal.

If you are waiting a few days to see if the pain subsides, or if you are waiting for a dental appointment, you can safely manage the discomfort at home:

• Over-the-Counter Painkillers: Ibuprofen (Advil) or Acetaminophen (Tylenol) are excellent for reducing both pain and tissue inflammation.
• Warm Saltwater Rinses: Dissolve half a teaspoon of salt in a glass of warm water. Swish gently for 30 seconds to reduce gum inflammation and kill bacteria.
• Chew on the Other Side: Give the tooth a break. Eat soft foods (like yogurt, soup, and mashed potatoes) and chew exclusively on the opposite side of your mouth.
• Desensitizing Toothpaste: Use a toothpaste designed for sensitive teeth (containing potassium nitrate) and brush gently around the gumline.
• Avoid Extreme Temperatures: Skip the ice water and the piping hot coffee until the nerve settles down.

Do not try to tough it out if the pain changes from an annoyance to an agony. You should immediately call your Whistle Partner Clinic if you experience:

• Pain that persists throughout the night and prevents you from sleeping.
• A pimple-like bump (abscess) forming on the gums near the crown.
• Visible swelling in your gums, cheek, or jaw.
• The crown feels physically loose or wiggles when you touch it.
• A sudden, persistently foul taste or smell coming from the tooth.
• These are classic signs of an infection or irreversible nerve damage. They will not go away on their own.

Pain after a crown is usually just the tooth settling down after the trauma of being reshaped. In the vast majority of cases, it resolves within a week. But if the pain lingers, throbs, or spreads, do not wait it out. Dental crowns are meant to protect your smile, not punish you.

If your crown does not feel right, trust your gut. Book an appointment at your nearest Whistle Partner clinic today. A simple five-minute bite adjustment could be all that stands between you and a pain-free smile.
