After a filling, some sensitivity to cold and a little tenderness when biting is normal and usually settles within a few days to a couple of weeks. What’s not normal is sharp pain that lingers or worsens, a bite that feels high or “off” for more than a few days, or throbbing, spontaneous pain — those are worth a quick call. Knowing the difference saves you worry and helps you act at the right time.
Here’s a clear guide to what to expect after a filling, and the signs that mean you should get in touch.
Right after the appointment
If you had a local anaesthetic, your lip, cheek or tongue may stay numb for one to three hours. Avoid chewing on that side until the numbness fully wears off, because it’s easy to bite your cheek or tongue without feeling it — take particular care with children. Tooth-coloured (composite) fillings are set hard straight away, so you can eat once the numbness goes, though it’s sensible to start gently.
What’s normal in the first days
- Mild sensitivity to cold, and sometimes sweet, for a few days up to a couple of weeks
- Slight tenderness when biting on the tooth as it settles
- Gum tenderness around the area where we worked
- A tooth that feels ‘different’ or that your tongue keeps finding
These usually fade steadily. A desensitising or sensitive-teeth toothpaste can help in the meantime, and most people find the tooth feels completely normal within two to three weeks.
What’s not normal — call us
Get in touch if you have sharp pain that lingers well after the cold or hot is removed, pain that is getting worse rather than better after a few days, throbbing or spontaneous pain (especially at night), or a bite that still feels high or uneven after two or three days. A filling that feels rough, has a sharp edge, or has come out or chipped also needs a look. None of these are emergencies in most cases, but they’re easily fixed and shouldn’t be ignored.
The high-bite problem
If a new filling sits even fractionally too high, you hit it first every time you close, which can cause lingering soreness and sensitivity that won’t settle on its own. This is common, simple to fix, and not a reflection of anything going wrong — a quick bite adjustment that takes a few minutes usually resolves it. If your bite feels off for more than a couple of days, don’t tough it out; a small adjustment makes a big difference and protects the tooth from being overloaded.
Looking after the filling long term
Fillings last longest with the same habits that prevent decay in the first place: brush twice daily with fluoride toothpaste, clean between the teeth, limit frequent sugary or acidic snacks, and wear a night guard if you grind. Keep up regular check-ups so we can spot any wear, leakage or new decay around the edges early. No filling is permanent, but well-cared-for fillings can last many years.
When to book a review
If sensitivity is worsening, pain is keeping you up, or the bite still feels wrong after a few days, call us and we’ll review the tooth — usually a small, quick fix. Patients across Winmalee, Springwood and the Blue Mountains can call for advice or book a review whenever something doesn’t feel right after a filling.
FAQs
Q: Is it normal for a tooth to be sensitive after a filling?
A: Yes. Mild sensitivity to cold and some tenderness when biting is normal for a few days and up to a couple of weeks. It should steadily improve. Sharp, lingering or worsening pain is not normal — call us.
Q: How long should pain after a filling last?
A: Mild sensitivity usually settles within days to two or three weeks. If pain is increasing, throbbing, or lasts beyond that, book a review so we can check the bite and the tooth.
Q: Why does my bite feel high after a filling?
A: The filling may be sitting fractionally too high, so you hit it first when you close. It’s common and quickly fixed with a small bite adjustment. Don’t put up with it for more than a couple of days.
Q: When can I eat after a filling?
A: With a tooth-coloured filling you can eat once any numbness wears off, as it’s set hard immediately. Wait for full sensation to return so you don’t bite your cheek or tongue, and start gently.
Q: Can a filling fall out?
A: Occasionally a filling can chip or come loose, especially older ones or with heavy biting and grinding. If that happens, it’s not usually an emergency, but book a review to have it repaired.
Q: What if the pain is severe or throbbing?
A: Throbbing, spontaneous or worsening pain can mean the nerve is irritated or inflamed and needs assessment. Call us — sometimes the tooth settles, and sometimes it needs further treatment such as root canal therapy.
