How long after a filling can I eat?
After a white (composite) filling, which is hardened with a curing light, you can usually eat as soon as the local anaesthetic wears off, often within a few hours. A silver (amalgam) filling is usually given about 24 hours before hard chewing, and a temporary filling between root-canal visits needs soft food on the other side. At Creative Arts in Dubai, your dentist tells you which filling you have and how long to wait.

How long after a filling can I eat? Timings by treatment
Typical advice for each kind of filling. Always follow the instructions your own dentist gives, because they know the size and depth of the filling and how the tooth was before treatment.
| Treatment | When you can eat | First 24 hours | Avoid until told otherwise |
|---|---|---|---|
| White (composite) filling | Once the numbness has gone; the filling is hard straight away | Normal food, chewing gently if the tooth is tender | Biting very hard objects with the new filling |
| Glass-ionomer filling | Once numb feeling has gone; soft food first | Avoid very hard or sticky food on that side | Hard or sticky food for about a day |
| Silver (amalgam) filling | Soft food once numbness has gone | Chew on the other side while it fully sets | Hard chewing on that tooth for about 24 hours |
| Temporary filling (between root-canal visits) | Once numbness has gone | Soft food on the other side | Sticky, chewy and hard food on that tooth until the final restoration |
| Root canal, then permanent filling or crown | Once numbness has gone | Soft food; the tooth is often tender to bite for a few days | Biting hard on the tooth until a crown is fitted, if one is planned |
Numbness from a lower-jaw injection usually lasts longer than from an upper one. Wait until normal feeling returns to your lip, cheek and tongue.
Why is the numbness the real reason to wait?
Modern white fillings are set hard with a blue curing light before you leave the chair, so the filling itself does not need time. What needs time is the local anaesthetic. While your lip, cheek or tongue is numb, you cannot feel how hard you are biting or how hot something is. People, and especially children, can chew the inside of their cheek or lip without noticing, and the swelling and ulcer that follow often hurt more than the filling ever did. The NHS advises taking care not to injure the numb area until the anaesthetic has fully worn off.
Numbness from an upper tooth injection often fades within a couple of hours; a lower-jaw injection, which numbs a nerve supplying half of the lip and tongue, usually lasts longer. Our guide on how long dental numbness lasts covers the typical times and what to do if it lasts much longer than expected.
While you are still numb, it is generally fine to drink cool or room-temperature water carefully. Leave hot drinks, soup and chewing until feeling returns.
Can I drink coffee or tea after a filling?
Yes, once the numbness has gone. The two practical points are temperature and sensitivity. While you are numb, a hot drink can scald your lip or tongue without you noticing. After that, a freshly filled tooth can be sensitive to hot and cold for a few days or even a few weeks, especially after a deep filling, so lukewarm drinks are often more comfortable at first. Our guide to sensitivity after a filling explains what is normal and when it suggests the bite needs adjusting.
If you take sugar in your coffee or tea, the usual advice about frequent sugary drinks still applies: sipping them through the day keeps the mouth acidic and works against the tooth you have just had repaired. And if you are wondering whether to brush straight after, our guide on brushing after eating explains why waiting a little after acidic drinks is wiser.
When can I chew on a root-canal tooth?
A tooth that has just had root canal treatment is often tender to bite on for a few days. That comes from the tissues around the root tip, not from the filling, and usually settles with over-the-counter pain relief as directed on the pack. The American Association of Endodontists advises avoiding biting hard on the tooth until it has been restored, because a root-treated tooth, especially a back tooth, is more brittle and can crack.
In practice that means:
- Between visits, the tooth has a temporary filling. Eat soft food on the other side, and avoid sticky sweets, chewing gum, nuts and hard bread on that tooth.
- After the final filling, normal eating can usually resume once tenderness settles, but a back tooth waiting for a crown is still at risk of splitting, so keep hard foods to the other side.
- After the crown, the tooth can be used normally.
Delaying the crown for months is one of the commonest reasons root-treated teeth break; our guide to crowns after a root canal explains why, and our guide on what to do if a root-canal tooth breaks covers the options if it happens.
Lost your temporary filling?
A temporary is meant to seal the tooth between visits, and losing it lets food and bacteria into the canals. Call the clinic during opening hours, 10:00 to 20:00 daily, to have it replaced. Pharmacy temporary kits can protect the tooth briefly but are not a substitute.
What can I eat after a filling or root canal?
For the first day after a deep filling, a temporary filling or a root canal, choose foods that need little chewing and are not too hot or cold:
- Eggs, yoghurt, labneh and soft cheese.
- Rice, pasta, soft bread and porridge.
- Soups and stews served warm rather than hot.
- Hummus, mutabbal, soft beans and lentils.
- Flaked fish, minced or slow-cooked meat.
- Ripe banana, avocado and soft cooked vegetables.
Foods worth avoiding on the treated side until the dentist says otherwise include nuts, seeds, hard bread crusts, ice, toffee and other sticky sweets, chewing gum and very crunchy snacks. If you grind or clench your teeth, mention it: heavy night-time forces can crack a new filling or a root-treated tooth.

Root canal treatmentWhen should you call the dentist after eating?
Some discomfort is normal; these are not, and are worth a call to the clinic during opening hours:
- The bite feels high or the filled tooth hits first when you close. A small adjustment usually fixes the soreness this causes.
- Sharp pain when you bite, or pain when you release, which can mean a high spot or a crack.
- Pain that is getting worse after a few days rather than better, or that throbs on its own, especially after a deep filling close to the nerve.
- A piece of filling has come away or the tooth feels rough or sharp; our guide on what to do if a filling falls out explains how to protect it.
- After a root canal, pain or pressure lasting more than a few days, swelling, or an uneven bite.
Go to a hospital emergency department if there is facial swelling with fever, swelling spreading towards the eye or neck, or difficulty breathing or swallowing. For general pain patterns after treatment, see our guide to pain after a root canal.
Eating after a filling: tips for children
Children are the group most likely to bite a numb lip or cheek, often out of curiosity. Keep them on drinks only until feeling has returned, distract them from touching or chewing the area, and check the lip for a white, swollen patch afterwards, which is usually a bite injury that heals in days. If your child is anxious about the numb feeling, tell them in advance what to expect. Our fillings page explains how fillings are done for children and adults, and our guide to pharmacy temporary filling kits covers what they can and cannot do while you wait for an appointment.
