You have just had a dental crown placed. Some discomfort is expected. But how do you know whether the pain you are feeling is part of normal healing, or a sign that something needs attention?
This guide explains the common causes of post-crown pain, which symptoms are routine, and when you should contact your dentist.
Normal Sensitivity After Crown Placement
When a tooth is prepared for a crown, the outer structure is reshaped to make room for the restoration. This process, while performed under local anaesthetic, involves removing tooth structure close to the nerve. The nerve inside the tooth can become temporarily irritated.
Normal post-crown sensitivity typically involves:
- Mild aching for the first few days as the anaesthetic wears off
- Sensitivity to cold drinks and foods for one to two weeks
- Tenderness when biting on the new crown, particularly in the first week
- Minor gum soreness around the crown margin
This sensitivity generally resolves on its own. Over-the-counter pain relief such as ibuprofen or paracetamol can help manage discomfort during this period.
Problem 1: The Bite Is Too High
This is the most common cause of persistent pain after crown placement and the easiest to fix.
If the crown sits even a fraction of a millimetre too high, your tooth absorbs excessive force every time you close your mouth or chew. This creates a bruised feeling in the ligament around the tooth root. The pain often worsens throughout the day as you use the tooth more.
How to tell: the crowned tooth feels like it hits first when you close your teeth together, or chewing on that side produces a sharp or aching sensation.
If a high bite is confirmed, a clinician may adjust the contact after checking the crown and tooth. Appointment time and symptom response vary; persistent pain can have another cause and needs reassessment rather than repeated adjustment by assumption.
At Ivy Dental, bite adjustments after crown placement are part of the crown process and are included in your treatment.
Problem 2: Nerve Inflammation (Pulpitis)
If the original decay or damage extended close to the tooth nerve, the preparation process can push an already stressed nerve past its tolerance. This is called pulpitis, and it comes in two forms:
Reversible pulpitis: The nerve is inflamed but recovering. Symptoms include sharp sensitivity to cold that fades within a few seconds. This typically resolves within a few weeks without treatment.
Irreversible pulpitis: The nerve is damaged beyond recovery. Symptoms include spontaneous throbbing pain (not triggered by eating or drinking), pain that wakes you at night, lingering pain after cold or heat exposure (lasting more than 30 seconds), and pain that is not relieved by over-the-counter medication.
If your symptoms suggest irreversible pulpitis, root canal treatment may be needed. The crown is either removed and replaced afterward, or in some cases, the root canal can be performed through the crown by creating an access hole in the top.
Problem 3: The Crown Margin Is Open or Irritating the Gum
A well-fitting crown should sit flush against the tooth at the gum line. If the margin is slightly open or rough, it can trap plaque and irritate the surrounding gum tissue.
Signs of a margin issue:
- Persistent gum soreness or redness around the crown
- A catch when you floss around the crown
- An unpleasant taste or smell from the area
- Visible gap between crown and tooth
If caught early, this may be polished or adjusted. If the fit is significantly off, the crown may need to be remade. Discuss this with your dentist at your follow-up appointment.
Problem 4: Cracked Tooth Under the Crown
In rare cases, the tooth underneath may have an undetected crack that was not visible during preparation. Cracks can cause sharp pain on biting, particularly when releasing bite pressure. This is a tricky diagnosis because cracks do not always show on X-rays.
Your dentist may test for a crack by having you bite on a cotton roll or using a special bite stick on different parts of the crown. Treatment depends on the severity and location of the crack.
Problem 5: Referred Pain or Adjacent Issues
Sometimes the pain you attribute to your new crown is coming from a neighbouring tooth. The proximity of teeth can make it difficult to localise pain accurately, particularly in the back of the mouth.
Your dentist will test surrounding teeth as part of the assessment. This is another reason a review appointment matters rather than assuming the crowned tooth is at fault.
Book a review if your crown pain has not improved after two weeks. Call Ivy Dental on (07) 3266 7120.
When Pain After a Crown Is an Emergency
Contact your dentist urgently or visit the emergency clinic if:
- You develop swelling in your face, gum, or jaw
- Pain is severe and uncontrolled by over-the-counter medication
- You have a fever alongside dental pain
- The crown has come off completely and the exposed tooth is sensitive
How to Manage Mild Crown Pain at Home
While waiting for your review appointment or during the normal healing period:
- If over-the-counter pain relief is suitable for you, follow the product label. Ask a pharmacist or clinician before combining medicines.
- Avoid very hot or very cold foods and drinks on the affected side
- Chew on the opposite side for the first few days
- Use a desensitising toothpaste containing potassium nitrate or stannous fluoride
- Avoid sticky or very hard foods that could dislodge or stress the new crown
The Ivy Dental Approach to Crown Follow-Up
At Ivy Dental, every crown placement includes a follow-up review. We check the bite, assess the gum response, and confirm you are comfortable with the restoration. If adjustments are needed, we handle them promptly.
Our Everton Park and Nundah clinics are open seven days. If your crown is causing concern, call us on (07) 3266 7120 to explain the symptoms and ask whether an earlier assessment is appropriate and available.
