Sensitivity, pain and care after dental crowns: what's normal?
Sensitivity to hot and cold and slight gum tenderness are common in the first days after a crown and usually settle within a few days to a few weeks. A high bite, or pain that increases or throbs, should be checked.
What's normal after a crown
- Hot and cold sensitivity: Especially in vital teeth, this can last a few days to a few weeks.
- Gum tenderness: The gum is affected during preparation and impressions, so mild soreness for a few days is common.
- Feeling different: Your tongue takes a few days to adjust to new surfaces; speech may feel slightly different.
- Getting used to the look: Especially when many teeth are crowned, it can take time to get used to your new smile.
When should you contact the clinic?
| Symptom | Possible cause |
|---|---|
| That tooth hits first when you bite | High bite; fixed with a quick adjustment |
| Throbbing pain that wakes you at night | Nerve inflammation; root canal treatment may be needed |
| The crown is loose or has come off | Cement failure or a problem with the tooth underneath |
| Persistent bleeding or swelling at the gum line | Poor marginal fit or gum inflammation |
| Sensitivity that gets worse after weeks | Needs a detailed examination |
What to watch with temporary crowns
Temporary crowns, worn between the impression and the final crown, protect the tooth and maintain your appearance, but they aren't as strong as the final ones.
- Avoid sticky (chewing gum, toffee) and very hard foods.
- When flossing, slide the floss out sideways rather than pulling it up.
- If a temporary comes off, keep it and call the clinic; an uncovered tooth can shift if left too long.
How to protect your crowns
- Brush twice a day and floss or use interdental brushes daily
- Pay attention to cleaning the crown margins (where decay most often starts)
- A check-up and professional clean every six months
- A night guard if you grind
- Don't bite hard objects such as seeds, ice or pens
See our article on teeth grinding and types of dental crowns.
Can crowns cause odour or decay underneath?
Well-fitting, well-cleaned crowns shouldn't cause odour. Bad breath can be a sign of decay at the crown margin or gum inflammation. Read our guide to bleeding and receding gums, and if in doubt, book a check-up.
Frequently asked questions
How long does sensitivity last after a crown?
For most people it fades over a few days to two or three weeks. If it gets worse or turns into spontaneous pain, it needs checking.
Can I eat straight after a crown is fitted?
You can eat once the numbness has worn off. Depending on the cement used, you may be given extra advice for the first few hours.
Does sensitive toothpaste help?
Yes, toothpastes with potassium nitrate or similar ingredients can help reduce temporary sensitivity.
What should I do if a crown falls out?
Keep the crown and call the clinic. Don't try to glue it back yourself; both the tooth and the crown can be damaged.
