Why Does My Crown Hurt When I Put Pressure On?
Tucson, AZ

Dental crowns are designed to restore damaged or weakened teeth, providing strength, stability, and a natural appearance. So, if your dental crown hurts when you bite down or apply pressure, it’s a sign that something isn’t quite right. While mild discomfort can occur shortly after getting a crown, persistent or sharp pain requires attention from your dentist. In this blog, we’ll explain why your crown might hurt under pressure, what the possible causes are, and how your dentist can help relieve your discomfort.

Understanding Why a Crown Might Hurt

Dental crowns cover the visible part of a tooth, protecting it from further damage or decay. When a crown is properly fitted and the underlying tooth is healthy, it shouldn’t cause pain. However, pain or discomfort while chewing, biting, or even applying light pressure can indicate several underlying issues — from bite misalignment to nerve irritation or infection.

Let’s look at the most common causes in detail.

1. The Crown Is Too High

One of the most common reasons for pain when applying pressure is an improperly fitted crown. If the crown is slightly too high, it may interfere with your bite alignment. This means that when you close your mouth or chew, the crowned tooth contacts the opposing tooth before the others, creating excess pressure on that single tooth.

Symptoms:

• Pain or soreness when biting down
• Sensitivity when eating hard or chewy foods
• Jaw discomfort or headaches due to uneven bite pressure

Solution:
Your dentist can adjust the crown by reshaping its surface to align it with your bite properly. This is usually a quick and painless procedure.

2. Tooth Nerve Irritation or Inflammation

Even though the crown itself is artificial, the tooth beneath it still has a living nerve. If this nerve becomes irritated — due to decay, a deep filling, or trauma during the crown placement — it can cause pain when pressure is applied.

Symptoms:

• Sharp pain when chewing
• Sensitivity to hot or cold foods
• Throbbing pain that worsens at night

Solution:
Your dentist may take X-rays to check for inflammation or infection inside the tooth. In some cases, a root canal treatment might be needed to remove the affected nerve tissue and eliminate pain.

3. Gum Recession or Irritation

If your gums recede around the crown, part of the tooth root may become exposed. This exposed area is sensitive and can cause pain or tenderness when you bite down. Gum inflammation from poor oral hygiene or ill-fitting crowns can also contribute to discomfort.

Symptoms:

• Tender gums around the crown
• Sensitivity near the gumline
• Swelling or redness in the surrounding tissue

Solution:
Improving your oral hygiene, using a soft-bristled toothbrush, and visiting professional cleaning experts can help. In more severe cases, gum treatment or crown replacement may be needed.

4. Infection Under the Crown

Sometimes, an infection can develop beneath a crown if bacteria enter through tiny gaps between the crown and the tooth. This can occur if the crown doesn’t seal properly or if there was undetected decay before placement.

Symptoms:

• Constant, throbbing pain
• Swelling or pus near the tooth
• Pain that worsens when chewing or pressing on the crown

Solution:
An infected tooth may require root canal therapy to remove the bacteria and preserve the crown. In some cases, the crown may need to be removed to treat the underlying tooth.

5. Cracked Tooth Under the Crown

Even with a protective crown, the tooth underneath can still crack, especially if it has been weakened by previous fillings or trauma. A crack can lead to pain when chewing or applying pressure, as the fracture flexes and irritates the nerve.

Symptoms:

• Pain when biting or releasing pressure
• Discomfort that comes and goes
• Sensitivity to temperature changes

Solution:
A cracked tooth may require a root canal or, in severe cases, extraction. Your doctor will evaluate the damage using X-rays or other imaging tools.

6. Bruxism (Teeth Grinding)

If you grind or clench your teeth — especially at night — you’re putting extra stress on your crown and surrounding teeth. Over time, this pressure can cause the crown or the underlying tooth to become sore or even damaged.

Symptoms:

• Pain or soreness in multiple teeth
• Jaw or facial muscle discomfort
• Worn or chipped crown surface

Solution:
Wearing a custom nightguard can help protect your teeth and crowns from grinding pressure while you sleep.

7. Recent Crown Placement Sensitivity

After getting a new crown, it’s normal to experience mild sensitivity or soreness for a few days. The tissues around your tooth may need time to heal from the dental procedure, and your bite might feel slightly off until you adjust.

Symptoms:

• Mild discomfort when chewing
• Temporary sensitivity to pressure or temperature
• Fading pain within a few days

Solution:
If the pain persists for more than a week or worsens, visit your dentist to ensure a proper fit and proper healing.

When to See Your Dentist

Pain when applying pressure should never be ignored, especially if it persists for more than a few days. Early diagnosis can prevent complications such as infection or nerve damage. Your dentist will likely perform a bite test, X-ray, and a clinical examination to identify the cause and provide the right treatment.

How to Prevent Crown Pain

While some causes of crown pain are unavoidable, most discomfort can be prevented with proper dental care and mindful habits. A dental crown is an investment in your oral health, so protecting it is essential to ensure it lasts for many years. Here’s how to keep your crown — and the tooth beneath it — pain-free and healthy:

1. Maintain Excellent Oral Hygiene

Even though a crown covers your tooth, decay can still form at the gumline where the crown meets your natural tooth. Brush twice daily with fluoride toothpaste and use dental floss or interdental brushes to clean around the crown. Keeping your gums and surrounding teeth healthy reduces the risk of infection and inflammation.

2. Use a Soft-Bristled Toothbrush

A hard-bristled brush can irritate your gums or scratch the surface of your crown. Opt for a soft-bristled toothbrush and gentle brushing motions to clean effectively without damaging your dental work.

3. Avoid Hard or Sticky Foods

Chewing on hard foods like ice, nuts, or hard candies can crack or loosen a crown. Similarly, sticky foods such as caramel or taffy can pull the crown out of place. Try to chew these foods with the opposite side of your mouth or avoid them entirely.

4. Address Teeth Grinding (Bruxism)

If you grind or clench your teeth, especially at night, you put extra pressure on your crown. Over time, this can lead to cracks, pain, or crown failure. Ask your dentist about a custom nightguard to protect your teeth and reduce strain.

5. Schedule Regular Dental Checkups

Routine dental visits allow your dentist to monitor your crown’s fit and condition. Professional cleanings also help remove plaque buildup that can cause gum disease or decay near the crown margins. Regular checkups mean small issues can be caught before they cause pain.

6. Avoid Using Teeth as Tools

Never use your teeth to open packages, bite your nails, or hold objects. These habits can place unnecessary pressure on your crown and cause chips or fractures.

7. Follow Post-Crown Care Instructions

After receiving a new crown, follow your dentist’s care guidelines carefully. This includes avoiding certain foods immediately after placement, managing sensitivity with desensitizing toothpaste, and returning for follow-up adjustments if needed.

8. Pay Attention to Early Signs of Discomfort

If you notice minor sensitivity or discomfort when chewing, don’t ignore it. Early intervention can prevent a minor issue from escalating into a major repair. The sooner you visit your dentist, the easier and less expensive it is to fix the issue.

Conclusion

If your crown hurts when you put pressure on it, it’s often a sign that something is wrong — but the good news is, most causes are treatable. Whether it’s a high bite, nerve irritation, or an infection beneath the crown, your dentist can diagnose the issue and provide the right solution. Don’t ignore persistent pain; visit your dental office for a professional evaluation to protect your smile and restore comfort.
