Can You Eat After Getting A Cavity Filled? Everything You Need To Know

By Dr Anthony Hua
Have you ever found yourself hungry right after a dental appointment, wondering if it’s okay to eat after getting a cavity filled? It’s a common question that many patients have and understanding the dos and don’ts can make a significant difference in your recovery and comfort. In this blog, we’ll explore everything you need to know about eating after a cavity filling, offering you practical tips and guidelines to follow.

Understanding the Cavity Filling Procedure

When a cavity is present, the dentist usually removes the decayed portion of the tooth and fills the area with a material such as composite resin, amalgam, gold or porcelain. This procedure aims to restore the tooth’s function, shape and appearance while helping to prevent further decay.

Can You Eat Normally After a Cavity Filling?

The simple answer is that it depends. After a cavity filling, your mouth might still be numb from the anaesthetic used during the procedure. Eating right away can be tricky because you might accidentally bite your tongue, cheek or lip without realising it. It might be a good idea to wait until the numbness wears off before eating. This waiting period can vary, but it usually lasts between one and three hours.

How Long Do You Have to Wait to Eat After a Cavity Filling?

For many, the pressing question is, “How long do you have to wait to eat after a cavity filling?” The answer depends on the type of filling you received. For composite fillings, which harden quickly under a special light, you might be able to eat as soon as the numbness wears off. For amalgam (silver) fillings, it might be a good idea to wait at least 24 hours before chewing on that side of your mouth to allow the filling to set properly.

Resting after a cavity filling might not be necessary for everyone but taking it easy can help you avoid inadvertently harming the filling. If you feel any discomfort or sensitivity, it might be helpful to rest and avoid strenuous activities until you feel better.

What are the Dos and Don’ts After a Tooth Filling?

Here are some helpful tips to follow after getting a cavity filled:


  • Eat soft foods: You can opt for soups, mashed potatoes, smoothies and yoghurt until the numbness wears off.
  • Maintain oral hygiene: It’s advisable to brush and floss regularly, but be gentle around the filled tooth.
  • Monitor for discomfort: Some sensitivity can be expected, but if you notice severe pain or discomfort, consider reaching out to your dentist.


  • Avoid hard and sticky foods: These might damage the filling or cause discomfort.
  • Don’t chew immediately: Waiting until the numbness subsides can help prevent accidental bites.
  • Avoid hot or cold foods and drinks: Extreme temperatures might cause sensitivity and discomfort in the filled tooth.
