Key Takeaways
- Composite fillings set under a curing light, so you can eat once the anaesthetic wears off.
- Metal fillings need about 24 hours to harden.
- Mild tenderness and sensitivity are common for a few days.
- Persistent pain, a lost filling, or a bite that won’t settle are reasons to call your dentist.
- Soft, non-sticky foods protect a new filling in its first days.
Immediate Aftercare Following Dental Fillings
The numbness from your dental filling fades within a few hours of your appointment. Wait until it wears off before eating or drinking, so you don’t bite your cheek, tongue, or lip without noticing. Your tooth may feel different for the first day as it settles into your bite.
Understanding Post-Filling Sensations
Tingling, mild tenderness, and a change in how your bite feels are common in the first 24 to 48 hours. These sensations mean the tooth is adjusting, not that something has gone wrong. If your bite still feels high or uneven after a day or two, your dentist can check and adjust it. Read more about bite imbalance after a filling if it doesn’t settle on its own.
Composite resin needs less drilling than older filling materials, so more of your natural tooth stays intact. That’s one reason aftercare for composite fillings tends to be simpler than for older materials.
Managing Initial Discomfort
Mild soreness after the anaesthetic wears off is common in the first day or two. Over-the-counter pain relief such as ibuprofen can ease discomfort and swelling. Check with your dentist first if you have an existing health condition or take other medication.
Sensitivity to hot and cold is also common, and a desensitising toothpaste can help in the meantime. If sensitivity carries on for more than a week or two, book a check-up with Casa Dental, or read our guide to tooth sensitivity after a filling for a full breakdown of causes and treatment.
Navigating Eating and Drinking After Dental Work
When you can eat again depends on the type of filling you received.
Timelines for Eating Based on Tooth Filling Type
Composite fillings set under a curing light during your appointment, so you can eat as soon as the anaesthetic wears off. Metal (amalgam) fillings take about 24 hours to harden, so avoid chewing on that side of your mouth until then.
Start with soft foods such as mashed potato, scrambled eggs, yoghurt, or soup. These put little pressure on a new filling while it settles in.
Foods That May Cause Complications
Hard, sticky, and chewy foods can crack or dislodge a new filling. Steer clear of nuts, ice, caramel, and chewing gum for the first few days.
Acidic foods and drinks, such as citrus fruit and fizzy drinks, can irritate a tooth that’s still settling. Extreme temperatures, hot coffee or iced drinks, can trigger sharp sensitivity while any numbness is wearing off.
Alcohol can irritate the treated area and slow healing on the first day. Hold off until any numbness and tenderness have passed.
Caring for Your Teeth After Fillings
Good oral hygiene protects a new filling from decay and keeps it in place.
Dental Hygiene Practices Post-Filling
Brush with a soft-bristled toothbrush and use light pressure around the filled tooth. Chew on the opposite side of your mouth for the first day if the area still feels tender.
Floss as usual, guiding the thread between teeth instead of snapping it into place. This protects the edge of the filling from chipping.
Natural Remedies: A Soothing Alternative?
A warm salt water rinse can ease mild swelling and keep the area clean. Dissolve half a teaspoon of salt in a cup of warm water and rinse for 30 seconds, a few times a day.
This isn’t a substitute for medication if pain is more than mild. If discomfort doesn’t ease, contact Casa Dental for a check-up.
When to Contact Your Dentist After a Filling
A few signs point to a problem rather than normal healing:
- Pain that gets worse, or lasts beyond a week or two, instead of easing
- A filling that feels loose, or one that comes out
- A visible crack or chip in the filling
- Swelling, or a bad taste that doesn’t go away
- A bite that still feels uneven after a few days
Any of these are reasons to book a check-up rather than wait it out. In rare cases, ongoing pain after a filling means the tooth needs a root canal instead. Our guide to the difference between a cavity filling and a root canal explains when that’s likely and what the treatment involves.
If your filling comes out, avoid chewing on that tooth and call your dental clinic as soon as you can. Leaving the tooth exposed for too long raises the risk of further decay.
Healing Well After Your Filling
Aftercare for a filling is short: mind what you eat for the first day, brush with care, and watch for the signs above. Most patients are back to normal within a day or two, with no special routine needed after that.

Frequently Asked Questions
What should I do after a dental filling?
Avoid eating until the anaesthetic wears off, stick to soft foods for the first day, and brush with a light touch around the treated tooth. Mild sensitivity is common in the first few days.
Can I eat right after a filling?
If you had a composite (tooth-coloured) filling, yes, once the numbness wears off. Metal fillings need about 24 hours to harden, so avoid chewing on that tooth until then.
What's the best way to manage pain after a filling?
Over-the-counter pain relief such as ibuprofen can help with discomfort and swelling. Speak to your dentist if pain persists beyond a few days or feels severe.
Can I smoke after a dental filling?
It’s best to avoid smoking for at least 24 hours. Smoking can slow healing and stain a composite filling early on.
Can I drink alcohol after a filling?
Hold off on alcohol until any numbness has worn off, so you don’t injure your mouth without realising it. Alcohol can also irritate the treated area while it’s still settling.
Can I exercise after a filling?
Light activity is fine once the anaesthetic wears off. Ease off if you feel discomfort, and give the tooth more time to settle.
Can I brush my teeth after a filling?
Yes, brush as normal with a light touch around the treated tooth. Wait until any numbness has worn off first, so you don’t injure your cheek or gum by accident.
