After a white (composite) filling you can usually eat as soon as the numbness has worn off, because the material is set hard during the appointment. After a silver (amalgam) filling it is best to wait around 24 hours before chewing anything hard on that side, since it takes longer to reach full strength.
Key takeaways
- White composite fillings are cured hard on the spot, so the main thing to wait for is the numbness to fade, usually one to a few hours.
- Silver amalgam fillings set more slowly. Avoid hard or chewy food on that side for about 24 hours.
- Wait until feeling returns before eating, to avoid biting your cheek, lip, or tongue.
- Mild sensitivity to hot, cold, or biting for a few days is normal. A bite that feels high or pain that builds should be checked.
White fillings versus silver fillings
The type of filling decides how long to wait before eating normally.
| Filling type | When it is set | When you can eat |
|---|---|---|
| White composite | Hardened with a curing light during the visit | Once numbness wears off; soft foods first |
| Silver amalgam | Sets over several hours, full strength by about 24 hours | Soft foods once numb wears off; avoid hard chewing for 24 hours |
Most fillings placed today are tooth-coloured composite, so for many people the wait is simply about the anaesthetic. Our guide on how long dental numbness lasts explains that timing.
Why waiting for numbness matters
Eating while your mouth is still numb is the most common way people hurt themselves after a filling. You can bite your cheek, lip, or tongue without feeling it, or burn yourself on hot food or drink. Waiting until normal sensation returns, usually one to three hours, avoids this. Take particular care with children.
What to eat in the first day
For the first day, gentle foods are kind to a freshly filled tooth.
- Good choices: yoghurt, eggs, soup that is warm not hot, mashed vegetables, pasta, soft fruit, and smoothies.
- Go easy on: very hot or very cold food and drink, which can trigger sensitivity.
- Avoid for a day: hard foods such as nuts and crusty bread, sticky foods such as toffee and chewing gum, and chewy lollies, all of which stress a new filling.
Chewing on the opposite side for the first day gives the tooth an easy start.
Sensitivity after a filling
It is normal for a filled tooth to be a little sensitive to cold, pressure, or sweetness for a few days, and sometimes up to a couple of weeks, as the tooth settles. This usually eases on its own. Using a toothpaste for sensitive teeth and avoiding extremes of temperature can help in the meantime. Our guide on sensitive teeth covers what helps and why. Sensitivity that gets worse rather than better, or sharp pain on biting, should be checked.
When to contact your dentist
- The bite feels high or uneven. If the filling feels like it hits first when you close, it may need a small adjustment. This is quick to fix and worth doing, since a high filling can cause ongoing ache.
- Pain builds instead of settling, or you get throbbing or spontaneous pain, which can signal the nerve is irritated. Our guide on reversible versus irreversible pulpitis explains the difference.
- The filling feels rough, cracked, or comes out. If a filling falls out, our guide on what to do if a filling falls out has the first steps.
Protecting the filling long term
A filling repairs a tooth, but the habits that caused the decay still matter. Cutting back on frequent sugar and acid, brushing twice a day, and cleaning between the teeth all protect the tooth and your other teeth. Our guide on the best and worst foods and drinks for teeth is a useful next read, and regular check-ups and x-rays catch new decay early.
Frequently asked questions
How long after a white filling can I eat?
Usually as soon as the numbness wears off, since composite is set hard during the appointment. Start with soft foods and chew on the other side for the first day.
Do I really need to wait 24 hours after a silver filling?
Avoid hard chewing on that side for about 24 hours while amalgam reaches full strength. Soft foods once the numbness fades are fine.
Why is my filled tooth sensitive to cold?
Mild cold sensitivity for a few days to a couple of weeks is common as the tooth settles. It usually fades. If it worsens, have it checked.
Can I drink coffee after a filling?
Wait until the numbness has gone so you do not burn yourself, and let it cool a little if the tooth is sensitive to heat.
My filling feels too tall when I bite. Is that normal?
A filling that feels high needs a small adjustment. It is a quick fix, so contact your dentist rather than living with it.
